Installing the A6828A Adapter
Overview of Installation Steps
Overview of Installation Steps
Here is a high-level view of the steps for installing the A6828A HBA:
Step 1. Review the recommendations for performance (see “Performance
Tuning” on page 11).
Step 2. Ensure that you have all the materials you will need (see “Preparing for
Installation” on page 12).
Step 3. Determine what you need to do (if anything) to configure auto
termination for the A6828A adapter (see “Auto Termination” on page 37).
Change the jumper position (see “Using the Jumper for Controlling Auto
If you do not need to change the position of the jumper, go to step 4.
•
•
SCSI ID (see “SCSI IDs” on page 25).
Maximum data transfer rate (see “Maximum Data Transfer Rate” on
page 27).
•
•
Bus width (see “Bus Width” on page 39).
Before setting the SCSI ID, Maximum data transfer rate, and Bus width
parameters through Boot Control Handler (BCH) menus, ensure that the
HP-UX system supports setting of these parameters in the BCH menus
(see Table 2-2 on page 22).
Step 7. Install the c8xxSCSI driver from the latest HP-UX bundle or HP IT
See “Installing the SCSI Driver” on page 50.

Installing the A6828A Adapter
Overview of Installation Steps
Step 8. If you will be using a disk array in a multi-host environment, ensure that
you have a LUN 0 configured (see “Configuring LUN 0” on page 52).
Step 9. Verify the installation (see “Verifying Installation” on page 55).

Installing the A6828A Adapter
Performance Tuning
Performance Tuning
To get the best performance from the A6828A adapter, HP recommends
the following things:
•
Increase the number specified for the scsi_max_qdepthkernel
tunable parameter:
— HP-UX 11.0: scsi_max_qdepthis a static tunable that you can
change in SAM (“Kernel Configuration” screen → “Configurable
Parameters” screen). Note that because this is a static tunable,
you will need to reboot the system after changing its value.
— HP-UX 11i: scsi_max_qdepthis a dynamic tunable; therefore,
no system reboot is needed to change the parameter’s value. See
“SCSI Queue Depth Management” in the HP-UX 11i Release
Notes for more information about this tunable.
If you see “queue full” messages in the /var/adm/syslog.logfile,
you can avoid those messages by reducing the value for
scsi_max_qdepth.
•
•
Install the A6828A adapter in a PCI4X or PCI2X slot in the HP-UX
system.
Do not put any Single Ended (SE) SCSI devices on the same SCSI
bus as Low Voltage Differential (LVD) SCSI devices. Doing this
changes the entire bus to SE, which limits the bus to Ultra SCSI (40
MB/s).
•
consider giving those devices the higher priorities on the bus (SCSI
ID 7 is usually assigned to the HBA). See “SCSI IDs” on page 25 for
more information.
•
•
Ensure to set the adapter’s maximum data transfer rate to the
correct rate (see “Maximum Data Transfer Rate” on page 27 for more
information).
Ensure to have the correct SCSI hardware configuration. Domain
Validation can detect some configuration problems (see “Domain
Validation” on page 98).

Installing the A6828A Adapter
Preparing for Installation
Preparing for Installation
Installation of the A6828A adapter requires disassembly of some system
components. Before beginning the installation, see the HP-UX system’s
manual for detailed instructions about installing host bus adapters in
the PCI slots.
To install the HBA, you need the following:
ꢀ
ꢀ
ꢀ
One HP A6828A SCSI HBA
One grounding (ESD) kit (shipped with A6828A)
Any other tools needed for installing components in the HP-UX
system (for example, screwdrivers); see the system’s documentation.
NOTE
The maximum number of SCSI HBAs you can install in any HP-UX
system is equal to the maximum number of corresponding card slots in
the system. For example, if a system has four PCI card slots, you can
install four SCSI PCI HBAs in that system, assuming that all the PCI
card slots are empty.
Check the latest SCSI support matrix for systems that support the
under the Networking and Communications section.

This section contains information on installing the A6828A HBA in an
HP-UX system (including Online Addition and Replacement [OLAR]).
WARNING
CAUTION
The installation procedures in this section require opening the
computer cabinet, which might expose you to high-energy
(high-amperage) circuits and sharp edges in the equipment
chassis. Ensure to remove all rings, watches, and other jewelry
before opening the cabinet.
The A6828A adapter contains electronic components that can easily be
damaged by small amount of static electricity. To avoid damage, follow
these guidelines:
•
Store the adapter in its antistatic plastic bag until you are ready to
install it.
•
•
Work in a static-free area, if possible.
Handle the adapter by the edges only. Do not touch electronic
components or electrical traces.
•
•
•
If you must lay the adapter down, place it on a non-conductive mat or
surface.
Use the ESD kit that is provided with the adapter. Follow the
instructions included with the kit.
Use a suitable ground—any exposed metal surface on the system
chassis.
Before beginning the installation, and without removing the adapter
from its antistatic bag, inspect the adapter for any signs of obvious
damage, such as chipped or loose components. Contact Hewlett-Packard
if the adapter is damaged.
Install the A6828A HBA in your HP-UX system according to the
documentation for the system.

NOTE
As stated earlier, although the A6828A HBA is supported on only 64-bit
HP-UX 11.0 and 11i, you can install the adapter in either a 32-bit or
slot, to get maximum performance. However, you can install the adapter
in a PCI2X, PCI1X, or shared PCI slot, if necessary.
When you have finished installing the A6828A HBA, go to section
“Connecting External SCSI Peripherals” on page 19.
Online Addition and Replacement—HP-UX 11i Only
Online Addition and Replacement (OLAR) is the ability of a PCI
host bus adapter to be replaced in or added to an HP-UX system
designed to support this feature, without the need for completely
shutting down and then rebooting the system or adversely affecting
other system components. The system hardware uses the per-slot power
control combined with OS support to enable this feature.
Check the latest SCSI support matrix that contains information on the
HP-UX systems that support OLAR of the A6828A adapter. The support
Communications section.
IMPORTANT
Certain “classes” of hardware are not intended for access by users. At
this time, this includes superdome systems. HP recommends that these
systems be opened by a qualified HP engineer only. Failure to observe
this requirement can invalidate any support agreement or warranty to
which the owner might otherwise be entitled.
You can add or replace an OLAR-compatible adapter in either of the
following ways:
•
•
Using the SAM utility.
Issuing command-line commands, through rad, that refer to the
c8xxOLAR script (/usr/sbin/olard.d/c8xx).

HP recommends that you use SAM instead of the radcommand to
perform OLAR procedures. This is because for the most part, SAM
prevents you from performing OLAR procedures that would adversely
affect other areas of the system. This is not true when you use the rad
command.
For detailed information on using either of these two procedures, see
Configuring HP-UX For Peripherals. You can order that document from
Hewlett-Packard, or you can view, download, and print it from

IMPORTANT
In many cases, other interface adapters and slots within the system are
dependent on the target adapter. For example, if the target adapter is a
multiple-channel adapter, suspending or deleting drivers for the target
adapter slot also suspends individual drivers for the multiple hardware
paths on that adapter.

Installing the A6828A Adapter
During an adapter replacement operation, SAM performs a Critical
Resource Analysis (CRA), which checks all channels on the target
adapter for critical resources that will be temporarily unavailable while
the adapter is shut down.
Planning and Preparation
As mentioned earlier, for the most part, SAM prevents you from
performing OLAR procedures that would adversly affect other areas of
the HP-UX system. See Configuring HP-UX For Peripherals for detailed
information.
Critical Resources
Replacing an adapter that is still operating can have adverse
consequences. As power to the slot must be off when the old adapter is
removed and the new adapter is inserted, you must consider the effects
of shutting down the adapter’s functions.
This is particularly important if no online failover or backup adapter to
pick up those functions is installed. For example:
•
Which mass storage devices will be temporarily disconnected when
the adapter is shut down?
•
Will a critical networking connection be lost?
A critical resource is one that would cause a system crash or prevent the
operation from completing successfully if the resources were temporarily
suspended or disconnected. For example, if the SCSI adapter to be
replaced connects to the unmirrored root disk or swap space, the system
will crash when the adapter is shut down.
During an OLAR procedure, it is essential to check the targeted adapter
for critical resources, as well as the effects of existing disk mirrors and
other situations where an adapter’s functions can be taken over by
another adapter that will not be affected.
As mentioned earlier, SAM performs a thorough CRA automatically, and
presents options based on its findings. If you determine that critical
resources will be affected by the procedure, you can replace the adapter
when the system is offline. On the other hand, if you are required to take
an action immediately, you can use the radcommand to try an online
addition of a backup adapter and deletion of the target adapter.

Chapter 2
Installing the A6828A Adapter
Installing the A6828A Adapter
Adapter Compatibility
This section explains adapter compatibility considerations for
performing OLA and OLR.
Online Addition (OLA) You can add multiple adapters at the same
time. While adding an adapter online, the first issue you must resolve is
whether the new adapter is compatible with the system. Each
OLAR-capable PCI slot provides a set amount of power. The replacement
adapter cannot require more than the available power.
The adapter must also operate at the slot’s bus frequency. A PCI adapter
must run at any frequency lower than its maximum capability, but an
adapter that could operate at only 33 MHz would not work on a bus
running at 66 MHz. The SCSI A6828A HBA operates at 66MHz. The rad
command provides information on the bus frequency and power available
at a slot, as well as other slot-related data.
If your system has one or more slots that support OLAR, and you want to
use OLA to install the A6828A in one of those slots, install the adapter in
your HP-UX system according to the procedure described in the
“Managing PCI Cards with OLAR” chapter of the Configuring HP-UX
Peripherals manual.
After you add a new A6828A adapter, SAM tries to locate the SCSI c8xx
driver. If SAM is unable to locate the driver, you cannot use the new
adapter until you install the driver (remember that driver installation
requires a system reboot). If SAM locates the driver, it determines
whether the new adapter is functional. If the adapter is not functional,
SAM displays an error message.
Online Replacement (OLR) While replacing an interface adapter
online, the replacement adapter must be identical to the adapter being
replaced, or at least be able to operate using the same driver as the
replaced adapter. This is referred to as like-for-like replacement and
should be adhered to, because using a similar but not identical adapter
can cause unpredictable results.
For example, a newer version of the target adapter that is identical to the
older adapter in terms of hardware might contain an updated firmware
version that could potentially conflict with the current driver. In
addition, the old adapter and new adapter must have the same PCI
identifiers (subsystem ID and device ID).
Chapter 2
17
Installing the A6828A Adapter
Installing the A6828A Adapter
The PCI specification allows a single physical adapter to contain more
than one channel. A single channel SCSI adapter cannot be replaced by a
dual channel adapter, even if the additional channel(s) on the adapter
are identical to the original SCSI adapter.
When the replacement adapter is added to the system, the appropriate
driver for that adapter must be configured in the kernel before beginning
the replacement operation. SAM ensures the correct driver is present.
(In most cases, the replacement adapter will be of the same type as an
adapter already in the system, and this requirement will be
automatically met.) Keep the following things in mind:
•
If the necessary driver is not present and the driver is a dynamically
loadable kernel module (DLKM), you can load it manually. See the
section “Dynamically Loadable Kernel Modules” in Configuring
HP-UX For Peripherals for more information.
•
If the driver is static and not configured in the kernel, then the
adapter cannot be added online. The adapter could be physically
inserted online, but no driver will claim it. Note that the SCSI c8xx
driver is a static driver.
If you have any question about the driver’s presence, or if you are not
certain that the replacement adapter is identical to the existing adapter,
you can use the ioscancommand together with the radcommand to
investigate.
SAM does not allow the A6828A HBA to be suspended in either of the
following situations:
•
•
If the adapter is being used (for example, if a file system is mounted).
If the CRA shows that a critical resource (for example, swap space or
the root file system) depends on the adapter.
After you replace an A6828A adapter online, SAM checks the
replacement adapter to make sure it is permitted, according to the
like-for-like rules. If the adapter is permitted, SAM automatically
activates it. If it is not permitted, SAM displays an error message.

Connecting External SCSI Peripherals
Connecting External SCSI Peripherals
The A6828A adapter is capable of communicating with Low Voltage
Differential (LVD) or Single Ended (SE) SCSI devices. LVD allows up to
12m cable lengths with multiple SCSI devices, or 25m point-to-point
connections.
IMPORTANT
As stated earlier in this chapter, do not mix LVD SCSI devices with SE
SCSI devices on the bus. If you do so, the entire SCSI bus will change to
SE. This will limit the bus performance to Ultra SCSI (40 MB/s).
Make all external SCSI bus connections to the A6828A adapter with
shielded, 68-pin LVD cables. The connectors on the cable are always
keyed to ensure proper mating.
NOTE
No cables or external terminators are shipped with the A6828A adapter.
Cables are usually shipped with the external SCSI devices, and you can
get external terminators for the A6828A HBA by ordering SCSI LVD/SE
terminator (HP product number C2370A).

When you have finished connecting the external devices, go to the next
section, “Specifying SCSI Parameters”.

Chapter 2
Installing the A6828A Adapter
Specifying SCSI Parameters
Specifying SCSI Parameters
To ensure proper operation of the A6828A adapter, the following SCSI
parameters that apply to the entire adapter must be configured correctly:
•
•
Maximum data transfer rate (SCSI rate)—see “Maximum Data
Transfer Rate” on page 27.
•
•
Auto termination state—see “Auto Termination” on page 37.
Bus width—see “Bus Width” on page 39.
NOTE
For some of these parameters, you can set the value through commands
in the Boot Console Handler (BCH) menus (on some HP-UX systems);
see Table 2-2 on page 22.
The BCH menus are displayed after the system has booted and before
the OS is running.
If the adapter is new, the SCSI driver uses a default setting suggested by
the system’s firmware, unless you specify a setting through the BCH
menus (if possible). This also happens if the slot in which you install the
adapter has no prior setting for a particular SCSI parameter
If the adapter is new and the slot does have a prior setting, the driver
uses that setting unless you change it through the BCH menus (if
possible).
If the adapter has been used in another slot or in a different system, you
must set the SCSI parameters for the adapter back to their default
values. This is because previously set values for the adapter cannot be
migrated to the new slot or system. See “Setting SCSI Parameters to
Default Values” on page 49 for the steps to follow.
Table 2-2 is a summary of the supported HP-UX systems and the SCSI
parameters you can set on each one. This table assumes that you have
correct version of PDC on the HP-UX system. To know about the correct

Chapter 2
Installing the A6828A Adapter
Specifying SCSI Parameters
SCSI IDs
You must assign a separate SCSI ID (0 through 15 for a 16-bit SCSI bus)
to the SCSI host bus adapter (HBA) and each SCSI device. The priority
of the device on the SCSI bus is determined by the SCSI ID of the device.
The order of SCSI ID priorities (from highest to lowest) is 7, 6, 5, 4, 3, 2,
1, 0, 15, 14, 13, 12, 11, 10, 9, and 8. A device with SCSI ID 7 has the
highest priority, and one with SCSI ID 8 has the lowest.
When you are assigning SCSI IDs, HP recommends you to give the SCSI
HBA higher priority than the other SCSI devices on the bus. SCSI ID 7 is
the preset SCSI ID for the A6828A SCSI HBA, thereby giving it the
highest priority on the SCSI bus. Set each of the other SCSI devices on
the bus to one of the remaining SCSI IDs.
In a multi-initiator (High Availability [HA]) configuration, multiple SCSI
HBAs are connected to the same SCSI bus. For such configuration, the
SCSI HBA that carries most of the traffic must be assigned a SCSI ID of
7 (highest priority). Later, you must change the SCSI ID of each of the
remaining SCSI HBAs on the bus from the preset setting (7) to the next
highest priority remaining SCSI IDs (for example, 6, 5, 4, and so on).
If you plan to boot your system from a hard disk drive on the SCSI bus,
you must assign that drive the next highest priority unassigned SCSI ID.
If there is only one SCSI HBA (SCSI ID = 7), the hard disk drive will be
assigned a SCSI ID of 6. If there are multiple SCSI HBAs, the hard disk
drive will be assigned the next highest priority SCSI ID available after
all of the SCSI HBAs have been assigned higher priority SCSI IDs.
Setting SCSI IDs
To set the SCSI ID of the A6828A HBA, see “Setting and Confirming
SCSI Parameters” on page 88.
The peripheral device SCSI IDs are usually set with jumpers or a switch
on the peripheral. Refer to the peripheral manufacturer’s instructions to
determine the ID of each device and how to change it.
IMPORTANT
You must not have duplicate SCSI IDs on a SCSI bus; the system may
hang or crash if you have duplicate SCSI IDs on the bus.
Chapter 2

Installing the A6828A Adapter
Specifying SCSI Parameters
Make necessary changes, if any, to the SCSI IDs and record the SCSI IDs
for future reference. To keep a record of the SCSI IDs, you can use

Installing the A6828A Adapter
Specifying SCSI Parameters
Maximum Data Transfer Rate
The firmware suggested default for the A6828A adapter’s maximum data
transfer rate is the adapter’s maximum speed (160 MB/s). The A6828A
can communicate with all LVD or SE devices that have speeds up to 160
MB/s. This includes the following speeds (synchronous communication
over a Wide bus):
•
•
•
•
Fast (20 MB/s)
Ultra (40 MB/s)
Ultra2 (80 MB/s)
Ultra160 (160 MB/s)
The actual transfer rate between the adapter and a SCSI device depends
on the transfer rate that was negotiated between the adapter and the
SCSI device. However, the actual rate will never be greater than the
maximum data transfer rate set for the adapter.
For example, if you set the A6828A’s maximum data transfer rate to
NOLIMIT(which is same as 160 MB/s, in this case), and then connect a
disk drive that has a maximum data transfer rate of Ultra2 (80 MB/s),
the actual transfer rate will be 80 MB/s.
TIP
HP recommends that you always set the A6828A’s maximum data
transfer rate to MAXor NOLIMIT(whichever is applicable to the system),
adapter and a specific SCSI device. Using MAXor NOLIMITallows the
adapter’s maximum transfer rate (160 MB/s) to be used.

Setting Maximum Data Transfer Rate for A6828A Host Bus
Adapter Installed in PA-RISC Based System
If the HP A6828A HBA is installed in a supported PA-RISC based
system, use the BCH menu to set the maximum data transfer rate.
The steps for setting the maximum data transfer rate through the BCH
menus (if you do not want to use the default suggested by the system’s
firmware) are mentioned later in this section.
NOTE
The following steps and examples are specific to an hp server rp7410.
Menus, command syntax, and responses might be slightly different on
other systems (for example, a maximum data transfer rate of Ultra2 is
not allowed on some HP-UX systems).
For command syntax and valid maximum data transfer rate values, HP
recommends you to use the online help for the scsicommand (type
help scsiwhen you are in the BCH “Service Menu”).
To display and optionally change the A6828A adapter’s maximum data
transfer rate in the BCH menus, perform the following steps:
Step 1. At the “Information Menu,” type fv(to display the PDC version). The
output is as follows:
FIRMWARE INFORMATION
Firmware Version:
15.3
To know about the correct PDC version information, see the latest SCSI
Communications section.
If you do not have a correct PDC version on your system, contact your HP
support representative.
Step 2. Determine the HBA’s path by performing the following steps:
a. If you are already at the “Main Menu,” type in(for “Information

right) digit is the channel number—0for channel A.
Step 3. Display (and optionally change) the HBA’s maximum data transfer rate
by performing the following steps:
a. If you are already at the “Main Menu,” type ser(for “Service Menu”);
go to step b.
If you are not at the “Main Menu,” type main(to return to the “Main

b. In the “Service Menu,” type the following command:
scsi path rate
where pathis the HBA’s path (from step 1).
Therefore, using the information for the HBA in the example in step
1, type the following:
scsi 0/0/10/0/0 rate
This displays the HBA’s maximum data transfer rate. The output is
as follows:

In this example, the HBA’s maximum data transfer rate is MAX

it allows the A6828A’s maximum data rate (160 MB/s) to be used.
30
Chapter 2
Installing the A6828A Adapter
Specifying SCSI Parameters
If you want to retain the maximum data transfer rate, type mainto go
back to the “Main Menu”.
If you want to change the data transfer rate (for example, to
troubleshoot communications between the adapter and an
Ultra-capable SCSI disk), go to step c.
c. If you are still in the “Service Menu,” type the following command:
scsi path rate new_data_rate
where, pathis the HBA’s path and new_data_rateis what you want
to change the HBA’s maximum data transfer rate to (ULTRA, for this
example).
Therefore, using the information for the HBA in step b, type the
following:
scsi 0/0/10/0/0 rate ultra
This changes the HBA’s maximum data transfer rate to ULTRA(40
MB/s).
To ensure that the data transfer rate has changed, you can repeat
step b to display the HBA’s transfer rate.
When your troubleshooting is complete, and you want to change the
adapter’s transfer rate back to MAX, go to step d.
d. If you are still in “Service Menu”, type the following command:
scsi path rate new_data_rate
where, pathis the HBA’s path and new_data_rateis what you want
to change the HBA’s maximum data transfer rate to (MAX, for this
example).
Therefore, using the information for the HBA in step c, type the
following:
scsi 0/0/10/0/0 rate nolimit
This changes the HBA’s maximum data transfer rate back to MAX(160
MB/s).
To ensure that the data transfer rate has changed, you can repeat
step b to display the HBA’s transfer rate.
When you are satisfied that the maximum data transfer rate is set
correctly, type mainto go back to the “Main Menu.”

When you configure the A6828A adapter’s auto termination parameter,
you specify the adapter’s role in the SCSI bus termination, because the
adapter might be a point of termination.
For more information on SCSI bus termination, including a tutorial, you
Controlling Auto Termination
You can control auto termination in the A6828A adapter (see “Using the
Jumper for Controlling Auto Termination” on page 38) depending upon
the HP-UX system in which the adapter is installed (see Table 2-2 on
page 22).

An external terminator might be required on the adapter, depending
on the SCSI bus configuration. If you need an external terminator for
the A6828A, use SCSI LVD/SE terminator (HP product number
C2370A).
Using the Jumper for Controlling Auto Termination
The A6828A adapter has one set of pins that control enabling and
disabling of the auto termination feature. The pins—labeled A_TERM
—are at the end of the HBA that is opposite to the bulkhead connectors.
Figure 1-1 on page 20 shows where the pin set is located on the adapter.
The default setting of the pin set on the A6828A HBA is the open
position (the jumper is on only one pin of its pin set). This is the auto
termination enabled state. In this state, the A6828A automatically
senses whether a cable from a powered SCSI device is attached and
provides the proper termination (depending on whether a powered device
is present).
To disable auto termination on the adapter, change the jumper from the
default open position to the shorted position (the jumper is on both pins
of the pin set). This is the auto termination disabled state.
The following Figure 2-2 shows the two jumper positions.

Bus Width
The firmware suggested default for the A6828A adapter’s bus width is
MAX(use the adapter’s maximum bus width [16 bits]). However, either of
these rates can be used for the A6828A:
•
•
8 bits (Narrow)
16 bits (Wide)
TIP
HP recommends you to always use the A6828A’s maximum bus width
(16 bits), unless you have Narrow (8-bit) devices on the bus and you are
experiencing problems with the connection.
You can set the A6828A’s bus width in one or two ways, depending on the
HP-UX system the adapter is installed in (refer to Table 2-2 on page 22).

Installing the A6828A Adapter
Specifying SCSI Parameters
Setting Bus Width for A6828A Host Bus Adapter Installed in
PA-RISC Based System
If the HP A6828A HBA is installed in a supported PA-RISC based
system, use the BCH menu to set the bus width.
The steps for setting the bus width through the BCH menus (if you do
not want to use the default suggested by the system’s firmware) are
given below.
NOTE
The following steps and examples are specific to HP server rp7410.
Menus, command syntax, and responses might be slightly different on
other systems.
For command syntax and valid bus width values, HP recommends you
to use the online help for the scsicommand (type help scsiwhen you
are in the BCH “Service Menu”).
To display and optionally change the A6828A adapter’s bus width in the
BCH menus, perform the following steps:
Step 1. Check the PDC (system firmware) version by performing the following
steps:
a. If you are already at the “Main Menu,” type in(for “Information
Menu”); go to step b.
If you are not at the “Main Menu,” type main(to return to the “Main
Menu”), type in(for “Information Menu”), and then go to step b.
b. At the “Information Menu,” type fv(to display the PDC version). The
output is as follows:
FIRMWARE INFORMATION
Firmware Version:
15.3
To know about the correct PDC version information, see the latest
Networking and Communications section.
If you do not have a correct PDC version on your system, contact your
HP support representative.

Chapter 2
Installing the A6828A Adapter
Specifying SCSI Parameters
Step 2. Determine the HBA’s path by doing the following:
a. If you are already at the “Main Menu,” type in(for “Information
Menu”); go to step b.
If you are not at the “Main Menu,” type main(to return to the “Main
Menu”), type in(for “Information Menu”), and then go to step b.
b. At the “Information Menu,” type io(to display I/O interface
information). The output is as follows:

In this example, the HBA’s path is 0/0/10/0/0(shown in bold in the
listing above, for highlighting purposes). Note that the last (farthest
right) digit is the channel number—0for channel A.
Step 3. Display (and optionally change) the HBA’s bus width by performing the
following steps:
a. If you are already at the “Main Menu,” type ser(for “Service Menu”);
go to step b.
If you are not at the “Main Menu,” type main(to return to the “Main
Menu”), type ser(for “Service Menu”), and then go to step b.
b. In the “Service Menu,” type the following command:
scsi path width
where, pathis the HBA’s path (from step 1).
Therefore, using the information for the HBA in the example in step
1, type the following:
scsi 0/0/10/0/0 width
This displays the HBA’s bus width. The output is as follows:

MAX
In this example, the HBA’s bus width is MAX(shown in bold in the
previous listing). As mentioned earlier, this is the firmware suggested
default setting.
If you want to retain the bus width, type mainto go back to the “Main
Menu”.
If you want to change the bus width (for example, because you have
Narrow devices on the SCSI bus and you are having problems with
the connection), go to step c.
c. If you are still in the “Service Menu,” type the following command:
scsi path width new_bus_width
where, pathis the HBA’s path and new_bus_widthis what you want
to set the HBA’s bus width to (8, for this example).
Therefore, using the information for the HBA in step b, type the
following:
scsi 6/0/4/0/0 width 8
This changes the HBA’s bus width to 8.
To ensure that the bus width has changed, you can repeat step b to
display the HBA’s bus width.
When you have fixed the problem with the connection, and you want
to change the adapter’s bus width back to MAX, go to step d.
d. If you are still in “Service Menu”, type the following command:
scsi path width new_bus_width
where, pathis the HBA’s path and new_bus_widthis what you want
to change the HBA’s bus width to (MAX, for this example).
Therefore, using the information for the HBA in step c above, type the
following:
scsi 0/0/10/0/0 width 0
This changes the HBA’s bus width back to MAX.
To ensure that the bus width has changed, you can repeat step b to
display the HBA’s bus width.

listing in the DRIVER NAMEcolumn.
In the preceding example, there are two versions of the LSI Logic
Ultra160 SCSI Driver. The <drvr_handle>designations that
correspond to the two LSI Logic Ultra SCSI Driversare 20and 21.
Step 3. Find the controller handle designation, <cntrl_handle>.
At the EFI Shell prompt, issue the drvcfg command as illustrated in
the following example:

Specifying SCSI Parameters
Setting SCSI Parameters to Default Values
You can set the SCSI parameters, except Auto Termination, for the
adapter to their default values through the BCH menus. The steps you
follow depend on the type of HP-UX system in which the adapter is
installed.
hp servers rp7410, rp8400, and superdome
On hp servers rp7410, rp8400, and superdome, set the SCSI parameters
to the default values by performing the following steps:
Step 1. If you are already at the “Main Menu,” type ser(for “Service Menu”); go
to step 2.
If you are not at the “Main Menu,” type main(to return to the “Main
Menu”), type ser(for “Service Menu”), and then go to step 2.
Step 2. In the “Service Menu,” type the following command:
scsi path default
where, pathis the HBA’s path. This sets all of the SCSI parameters for
the pathto their default values.
Step 3. Type mainto get back to the “Main Menu.”
All Other Servers
On all servers other than hp servers rp7410, rp8400, and superdome, set
the SCSI parameters to the default values by following the steps for
specifying each SCSI parameter (described earlier in this section).
You will need to know the default value—and how to specify it—for each
SCSI parameter. To know the valid SCSI parameter values, HP
recommends you to use the online help for the scsicommand (type
help scsiwhen you are in the BCH “Service Menu”).
Chapter 2
49
Installing the A6828A Adapter
Installing the SCSI Driver
Installing the SCSI Driver
On most of the supported HP-UX PA-RISC systems, the SCSI c720
driver is used with some of the SCSI interfaces. This driver is
automatically installed as part of the HP-UX 11.0 core OS and the
HP-UX 11i base Operating Environment (OE). Therefore, you do not
have to install it separately.
However, you must separately install the SCSI c8xxdriver, which is
used by the A6828A HBA in all the supported HP-UX systems. This
driver is available in the latest HP-UX bundle or at http://itrc.hp.com.
TIP
You should keep in mind that although the installation process installs
the c8xxdriver, it does not load the c8xxdriver into the HP-UX kernel
unless it detects one or more SCSI Ultra160 devices installed in the
HP-UX system. This is done to prevent the kernel from becoming
unnecessarily large.
Therefore, if Ultra160 devices (for example, a SCSI Ultra160 “add-in”
adapter [like the A6828A] or core I/O card) are already installed in the
HP-UX system, or if you will be installing an Ultra160 add-in adapter
later through OLA, you should install the c8xxdriver now. If no SCSI
Ultra160 devices are in the system, and you do not want to install any
Ultra160 add-in adapters later, do not install the c8xxdriver at this
time.
NOTE
You must install all patches before you install the bundle containing the
c8xxdriver.
The following is an overview of the steps you need to perform:
Step 1. Issue the swlistcommand to see which patches are already installed on
the system. You can get any patches you need to install from the HP IT
If you do not need to install any patches (other than the c8xxbundle), go

If you need to install one or more patches, go to step 2.
Step 2. Install any necessary patches.
Step 3. Follow the normal procedure to install the appropriate software bundle
for your HP-UX system’s OS or OE.
Step 4. Issue the swlistcommand to ensure that the necessary patches and the
c8xxdriver are present.
Step 5. Check to see if the c8xxdriver is loaded in the kernel by doing one of the
following two things:
•
Use SAM, as follows:
1. Select the “Kernel Configuration” icon.
2. Select the “Drivers” icon.
3. In the “Kernel Configuration” screen, check to see if the c8xx
driver is in the kernel.
•
what /stand/vmunix | grep scsi_c8xx.c
Check to see if the c8xxdriver is listed.
If the driver is in the kernel, go to the section, “Configuring LUN 0” on
page 52.
If the driver is not in the kernel, go to step 6.
Step 6. Load the c8xxdriver into the kernel through SAM:
a. Select the “Kernel Configuration” icon.
b. Select the “Drivers” icon.
c. In the “Kernel Configuration” screen, follow the normal steps for
loading the driver into the kernel (and building a new kernel).
NOTE
You need to reboot the system after completing these steps.
Once you have confirmed that the c8xxdriver is in the kernel, go to
section, “Configuring LUN 0” on page 52.

Configuring LUN 0
Configuring LUN 0
For a disk array that is in a multi-host environment, the SCSI standard
requires a LUN 0 in certain scenarios:
•
If the disk array is connected to the A6828A adapter, and you plan to
boot from that array, the disk array must be configured as LUN 0. Do
not configure the LUN with any LUN security (that is, do not restrict
access).
•
If the disk array is connected to an A6828A adapter installed in an
HP-UX system that is running from a separate boot disk, the disk
array must be configured with LUN 0; otherwise, the ioscan
command will not detect all of the LUNs present in the disk array.
Once you have determined that LUN 0—if it is required—is configured
correctly, go to the section, “Verifying Installation” on page 55.

Installing the A6828A Adapter
Verifying Installation
Verifying Installation
After installing the adapter and the c8xxdriver and attaching the
peripheral devices, verify that all the components are working by
performing the following steps:
Step 1. To verify that the adapter is correctly installed, issue the following
command:
ioscan -fnk
The applicable line in the ioscanoutput can have the following form:
ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6828-60101
The third column shows the hardware path of the PCI device/function
(shown in bold in the above example, for highlighting purposes). The
A6828A supports one PCI device/function (because it has only one
channel). In addition, since this is a single channel HBA, one line is
listed for channel A of the adapter (denoted by a 0as the last digit in the
hardware path).
Step 2. In the same line of the ioscanoutput, verify that the adapter is claimed
by the SCSI c8xxdriver by looking at the fifth column of information
(shown in bold in the example below, for highlighting purposes).
ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6828-60101
If the adapter is not claimed, see “If the A6828A Adapter is Not Claimed”
on page 86.
Step 3. In the same line of the ioscanoutput, verify that the SCSI driver and
adapter information are displayed (shown in bold in the example below,
for highlighting purposes).
ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6828-60101
In this example, the SCSI driver information is c8xx(name of the
driver), and the adapter information is as follows:
• SCSI C1010—The type of HBA (SCSI) and the type of Ultra160
controller (C1010).
Chapter 2
55
Installing the A6828A Adapter
Verifying Installation
• Ultra160—The HBA’s maximum data transfer rate. This can be
Ultra160, Ultra2, Ultra, Fast, or Async. You should keep the
following in mind:
rate set for the HBA.
— This is either the firmware default or the rate set through the
BCH menus, unless you attach an SE device, which causes the
entire bus to change to a transfer rate of Ultra (see “Performance
Tuning” on page 11).
• Wide—The HBA’s bus width. This can be Wideor Narrow.
• LVD—The HBA’s bus type. This can be LVDor Single-Ended. If no
bus type is shown, then the SCSI channel is disabled.
• A6828-60101—The HBA’s HP part number.
Step 4. In addition, in the ioscanoutput, the ctlline shows the adapter’s SCSI
ID in its hardware path (shown in bold in the example below, for
highlighting purposes).

Step 5. Verify that the devices you attached to the adapter are present in the
ioscanoutput. For example, a partial list may look like this:
disk 10 0/0/1/0/1.0.0 sdisk CLAIMED DEVICE
/dev/dsk/c1t0d0 /dev/rdsk/c1t0d0
disk 11 0/0/1/0/1.2.0 sdisk CLAIMED DEVICE

Installing the A6828A Adapter
Verifying Installation
TIP
When the system boots after installation, the insfcommand creates the
proper device files for the “ctl” interfaces (which are usually adapters)
and the SCSI devices attached to the A6828A adapter. Sometimes,
though, it does not create all of the needed device files.
One situation when this happens is when you attach SCSI disks to the
adapter after the system boots and the adapter is already installed in the
system.
In the ioscanoutput, if you see a SCSI device listed without the second
line, that means you are missing that device’s device files. To fix the
problem, issue the insf -ecommand, which creates all of the device
files.
For more information on the ioscancommand, see the ioscan(1M)man
page.

Installing the A6828A Adapter
Using the Extended Firmware Interface Flash Utility
Using the Extended Firmware Interface Flash
Utility
If you are installing the A6829A SCSI HBA in an Itanium-based
system, use the Extended Firmware Interface (EFI) flash utility to verify
the firmware version, or to flash and save firmware images onto the
A6829A HBA.
The EFI flash utility is supported on HP A6829A SCSI HBA, which is
based on the 53C1010 LSI Logic SCSI chip.
Features
The features of the EFI flash utility are as follows:
•
•
•
•
Supports HBA selection for updating the SCSI parameters.
Displays the firmware version on an HBA or in a firmware image file.
Supports a menu driven mode.
Allows you to flash the EFI option ROM images.
Description
This utility allows you to update the HBA flash memory with the LSI
Logic EFI driver. New versions of these images are released periodically.
Your HBA must have a flash memory to use this utility.
WARNING
Do not attempt to use this utility to flash any binaries other than
the EFI option ROM images.
The executable file name of the EFI utility is EFI8XXFL.EFI. This file,
and any firmware image files you need, must be stored on a diskette or
CD-ROM. These files must not be stored on a hard disk, because if the
flash fails, there is no way to recover these files. Moreover, the hard disk
may not be accessible.
58
Chapter 2
Installing the A6828A Adapter
Using the Extended Firmware Interface Flash Utility
The EFI utility should be executed from a diskette or CD-ROM. For EFI
based systems without a floppy diskette drive, burning the EFI utility
and other firmware images onto a CD-ROM allows proper execution, but
with reduced functionality. In such a situation, you will not be able to
save an image of the flash memory to the CD-ROM.
Preparation
While booting the EFI enabled systems, the diskette or CD-ROM
containing the EFI utility needs to be in the drive to allow device
mapping. The EFI utility and firmware image files are located in the root
directory or in a subdirectory on the diskette or CD-ROM.
Boot the system to the EFI shell prompt. The floppy diskette drive or
CD-ROM drive should appear in the list of mapped devices as fs0.
In systems with a floppy drive, type fs0at the EFI shell prompt to
change to this device.
Menu Driven Mode
If the EFI utility and firmware image files are located in the root
directory, enter the efi8xxflcommand at the prompt as illustrated
below; otherwise, move to the directory in which these files are located
and continue.

The main window allows you to choose the SCSI chip corresponding to
the path where you want to perform the selected tasks. Dual channel
cards display two entries (one for each SCSI chip) on this screen.
In the aforementioned example, the system has three HBAs - one each on
the 0x15, 0x3F, and 0x16buses. The HBA on bus 0x3Fis a dual-channel
HBA (func 0x00 and func 0x01) with flash memory part number
Am29F010. Since both the channels of a dual channel board share the
same flash memory, only one of the paths needs to be chosen. If separate
updates are performed through both the paths, the flash memory is not
affected.
NOTE
Each update overwrites the existing contents of the flash memory.
The segment value of the HBA corresponding to Choicenumber 5is
0x01. This indicates that the HBA resides on PCI segment 1. The other
HBAs reside on PCI segment 0, as the segment value for other HBAs is
0x00.
The SYMC1010following LSI Logic, Inc.indicates that the HBAs use
the 53C1010 LSI SCSI chip, which is supported by this EFI utility.
If a device does not contain an LSI Logic SCSI chip supported by the EFI
utility, the lines listing the chip numbers do not appear in the display.
The HP A6829A SCSI HBA is based on the LSI Logic 53C1010 SCSI
chip.

General Procedure
General Procedure
In general, perform the following steps to troubleshoot the A6828A
adapter:
Step 1. Check the connection.
Ensure that the correct cable is used, connected, and operating properly.
In addition, ensure that none of the connectors have any bent pins. If you
do not find any problems with the connection, go to step 2.
Step 2. Check SCSI bus compatibility.
Use the commands in the BCH menus to ensure that the data transfer
rates of the A6828A adapter and the attached devices are compatible
(see “Setting and Confirming SCSI Parameters” on page 70). If the
transfer rates of the adapter and attached devices are compatible, go to
step 3.
Step 3. Check the adapter.
Inspect the adapter to ensure that it is seated properly in the PCI slot. If
necessary, power down the system, reseat the adapter, and restart the
If a visual inspection of the adapter and cable does not reveal any
problems, or if an action taken as a result of the inspection does not
produce a working adapter, go to step 4.
Step 4. Run the Support Tools Manager (STM) diagnostics application (see
“Using Support Tools Manager (STM)” on page 85).
If diagnostics determine that the adapter is defective, you must replace
it. Contact your local Hewlett-Packard customer representative or call
the Hewlett-Packard Response Center.

Troubleshooting
Creating Missing Device Files
Creating Missing Device Files
When the system boots after installation, the insfcommand creates the
proper device files for the “ctl” interfaces (which are usually adapters)
and the SCSI devices attached to the A6828A adapter. Sometimes,
though, it does not create all of the needed device files. (One situation
where this happens is when you attach SCSI disks to the adapter after
the system boots [and the adapter is already installed in the system].)
The following is an example of what the output of the ioscancommand
might look like when you issue it to verify the A6828A installation (see
“Verifying Installation” on page 72):

In the ioscanoutput above, the second line shows the disks’ device files
(/dev/...[shown in bold in the example above, for highlighting
purposes]). If you see a disk (or other SCSI devices) listed without the
second line, that means you are missing that device’s device files. To fix
the problem, issue the insf -ecommand, which creates all of the device
files.

Troubleshooting
If the A6828A Adapter is Not Claimed
If the A6828A Adapter is Not Claimed
If the A6828A adapter is not claimed (it shows as “UNCLAIMED” in the
output from the ioscancommand), the most likely reason is that you
installed the c8xxdriver but did not install the required patches.
To fix this problem, perform the following steps:
Step 1. Confirm that the c8xxdriver has not claimed the A6828A adapter, by
issuing the following command:
ioscan -f
The applicable line in the ioscanoutput could look like this:
unknown -1 0/0/10/0/0
UNCLAIMED UNKNOWN
PCI SCSI (10000021)
In the example above, the pieces of information that are
abnormal—indicating an unclaimed adapter—are shown in bold, for
highlighting purposes. (To see what “normal” output could look like, see
“Verifying Installation” on page 72 or step 6 below.)
Step 2. Check to see if the c8xxdriver is loaded in the kernel, by doing one of the
following two things:
•
Use SAM, as follows:
1. Select the “Kernel Configuration” icon.
2. Select the “Drivers” icon.
3. On the “Kernel Configuration” screen, check to see if the c8xx
driver is in the kernel.
•
Issue the following command:
what /stand/vmunix | grep scsi_c8xx.c
Check to see if the c8xxdriver is listed.
If the driver is in the kernel but the A6828A adapter is still not claimed,
go to step 4.
If the driver is not in the kernel, go to step 3.
68
Chapter 3
Troubleshooting
If the A6828A Adapter is Not Claimed
Step 3. Load the c8xxdriver into the kernel through SAM by performing the
following steps:
a. Select the “Kernel Configuration” icon.
b. Select the “Drivers” icon.
c. In the “Kernel Configuration” screen, follow the normal steps for
loading the driver into the kernel (and building a new kernel).
Note that you will need to reboot the system as part of these steps.
Step 4. If the c8xxdriver is in the kernel but the A6828A adapter is still not
claimed, check the /var/adm/syslog.logfile for errors like these:
Jan 11 16:08:00 svt38 vmunix: SCSI: SIOP RAM address out of range
Jan 11 16:12:05 svt38 vmunix: init of hardware not successful. id=10000021 and
my_isc=24
If you encounter such errors, you must install the patches required for
the c8xxdriver. You can find information on the patches you need to
install in the following places: (1) the README file for the March 2002
(and later) HWE1100patch bundle (for HP-UX 11.0), and (2) the March
2002 (and later) HP-UX 11i Release Notes (for HP-UX 11i).
Step 5. Follow the normal procedure to install the required patches.
Note that you will need to reboot the system as part of these steps.
Step 6. After the system reboots, verify that the adapter is now claimed, by
issuing the following command:
ioscan -fnk
The applicable line in the ioscanoutput could look like this:
ext_bus 0 0/0/10/0/0 c8xx CLAIMED INTERFACE SCSI C1010 Ultra160 Wide LVD A6828-60101
In the example above, the pieces of information that are
normal—indicating a claimed adapter—are shown in bold, for
highlighting purposes.
If the A6828A adapter is claimed, you have fixed the problem.
If the adapter is still not claimed, repeat steps 2 through 6, as needed.

At the EFI Shell prompt, issue the drvcfg command as illustrated in
the following example:
Shell> drvcfg

From the output of the drvcfg command, look for the line(s) where the
NNin Drv[NN]is same as the <drvr_handle>for the driver(s) you are
using.
The 2nd column, Ctrl [NN], contains the corresponding
<cntrl_handle>, where NNis the controller handle. For example,
controller handle 1A, 1B, 1D, 1E, and 23correspond to driver handle 20,
and controller handle 22corresponds to driver handle 21.
Step 4. Once the driver handle and the controller handle are identified, the SCSI
parameters can be displayed and set for any driver and corresponding
controller (HBA) on the SCSI bus.
Enter the drvcfg -s <drvr_handle> <cntrl_handle> command at
EFI shell prompt. The Global Properties screen containing a list of the
controller (HBA) to which the controller handle corresponds is displayed;

Domain Validation
Domain Validation
Domain Validation provides a way to automatically detect, and if
necessary, compensate for hardware that is not performing to the
optimal level. It does this by reducing the data transfer rate and bus
width. This allows you to have data integrity even if data transfers
cannot occur at the maximum data transfer rate supported by the HBA.
If Domain Validation does reduce the rate and bus width, a message is
generated so that you can correct the problem.
Domain Validation is automatically enabled for all SCSI devices on the
bus, as long as you have set the HBA’s maximum data transfer rate to its
maximum speed (160 MB/s for the A6828A). See “Maximum Data
Transfer Rate” on page 45 for more information on setting the HBA’s
transfer rate.
TIP
If necessary, you can disable Domain Validation—if you want to do
diagnostics, for example—by lowering the transfer rate to less than
Ultra160 through the commands in the BCH menus (see “Maximum
Data Transfer Rate” on page 45).
Domain Validation runs each time the initiator device and target device
negotiate the transfer rate and bus width. A few things that can cause
this are as follows:
•
A protocol violation or some other exception condition occurs on the
SCSI bus.
•
A SCSI device is powered on and then I/O occurs to that device.
Things that Domain Validation might detect are as follows:
•
Incorrect or improper SCSI bus termination (for example, a missing
or bad terminator or an incorrect auto termination setting)
•
•
•
•
Incorrect hardware configuration
Cables with the wrong impedance
Major cable errors (for example, a broken wire within a cable)
SCSI device spacing problems
80
Chapter 3
Troubleshooting
Domain Validation
•
Path width errors (for example, a Narrow cable used with a Wide
SCSI device)
•
•
•
Damaged or marginal transceivers
Excessive cross talk
Excessive system noise
When Domain Validation determines that communication with the
target device is not possible at the maximum data transfer rate
supported by the HBA (Ultra160), it writes the following warning
message to the /var/adm/syslog.logfile:
SCSI:Ultra160 SCSI Adapter at hw_path: fallback occurred for
target target_ID. Possible causes are improper termination,
improper cabling, or malfunctioning hardware. Verify the
hardware at the next opportunity.
Later, it “falls back” (lowers the transfer rate and bus width) by one level,
according to Table 3-1 below.

NOTE
The number of entries in Table 3-1 above is subject to change. We are
providing it here to give you an example of how the fallback procedure
works.
As mentioned earlier, Domain Validation tests are run on all targets on
the SCSI bus, even those targets that do not have Ultra160 capabilities.
Therefore, the starting point in Table 3-1 depends on the parameters
that were negotiated for any particular target. In addition, since a SCSI
bus can contain up to 15 targets, different SCSI parameters might be in
effect at any one time on the bus (because Domain Validation is running
on all of the targets at the same time).
If a fallback does occur and you fix the problem with the target
hardware, you need to power cycle (power off and then power on) the
target hardware and then run ioscanwithout the -koption (you can
specify any other options, though). This restarts Domain Validation for
that target and restores the negotiated parameters to the highest
possible transfer rate and bus width. Next, look in the
/var/adm/syslog.logfile for any new “fallback” warning messages
82
Chapter 3
Troubleshooting
Domain Validation
(shown earlier in this section). If the problem was fixed properly and
Domain Validation is at the correct level, you will not see any new
warning messages.
As an example, if the parameters originally negotiated during the
normal SCSI initiator/target communications are equivalent to
Ultra160, but Domain Validation determines that the SCSI bus or the
target cannot support that data transfer rate, Domain Validation falls
back to Ultra2 Wide. Later, Domain Validation repeats its test. If the bus
or target still cannot support the transfer rate, Domain Validation falls
back another level, to Ultra2 Narrow. As long as failures occur, fallback
continues, one level at a time, until the last level in Table 3-1
(Asynchronous) is reached. (Note that a “fallback” warning
message—shown earlier in this section—is not generated each time
Domain Validation falls back a level, but only when it successfully settles
at a level.) If the last level is reached and a failure still occurs, the
following message is written to the /var/adm/syslog.logfile:
SCSI:Ultra160 SCSI Adapter at hw_path: Error: The domain
validation test for target target_ID determined that
communication may not be possible to this target. Verify the
hardware at the next opportunity.
To be able to restore communication to the target hardware, you must fix
the problem with the target, power cycle (power off and then power on)
the target, and then run ioscanwithout the -koption to restart Domain
Validation and renegotiate the parameters for that target. Next, you
need to check /var/adm/syslog.logfor any new “fallback” warning
messages. The lack of new “fallback” messages means you successfully
fixed the problem, and the data transfer rate and bus width are at the
correct levels.
Note that when a Domain Validation test succeeds, no message is written
to the /var/adm/syslog.logfile. The reason is that this would generate
a large volume of messages, especially on a system that is used heavily.
Not only would this make the file very large, but the more important
warning and error messages would not be easy to see.
In addition, a SCSI selection timeout—when a target device does not
respond to selection within a certain length of time—will terminate a
Domain Validation test on a target, and the target will be considered to
be non-existent. This is so that a bus scan or system boot will not be
extended by Domain Validation waiting several times for a target that
does not exist.

83

Domain Validation
NOTE
A Domain Validation test that is terminated for one target does not affect
the tests being run on any of the other target devices on the SCSI bus.

Low Voltage Differential (LVD) A robust
design methodology that improves power
consumption, data integrity, cable lengths,
and support for multiple devices while
providing a migration path for increased I/O
performance.
O
operating system (OS) A program that
organizes the internal activities of the

operating system performs basic tasks such
as moving data to and from devices and
managing information in memory. It also
provides the user interface.
M
main memory The part of a computer’s
memory that is directly accessible by the
CPU (usually synonymous with RAM).
P
parity checking A way to verify the
accuracy of data transmitted over the SCSI
bus. One bit in the transfer is used to make
the sum of all the 1 bits either odd or even
(for odd or even parity). If the sum is not
correct, an error message appears. SCSI uses
odd parity for data transfer rates less than
160 MB/s.

SCSI device on the SCSI bus. Each SCSI bus
has fifteen available SCSI IDs numbered 0
through 15 for Wide SCSI or 0-7 for 8-bit
SCSI. The host bus adapter is usually
assigned ID 7, which gives it priority to
control the bus.
R
Random Access Memory (RAM) In
general, the computer’s primary working
memory in which program instructions and
data are stored and are accessible to the
CPU. Information can be written to and read
from RAM. The contents of RAM are lost
