Installing the A4800A Adapter  
Handling the A4800A Adapter  
Ha n d lin g th e A4800A Ad a p ter  
The host bus adapter is packaged with an ESD kit, which contains  
materials to prevent damage from static electricity during installation.  
CAUTION  
The adapter is highly susceptible to damage by electrostatic discharge  
during installation and routine maintenance procedures. Do not handle  
circuit boards without wearing a wrist strap fastened to a good earth  
ground or to the system chassis.  
While you are installing the A4800A adapter, please follow these  
precautions:  
Keep the adapter in its shielded antistatic bag until you are ready to  
install it.  
Use a wrist strap or other ESD protection. Wrap the strap around  
your wrist and attach the copper end to a metal portion of the  
computer frame.  
Avoid working in carpeted areas.  
Gently place the adapter, printed circuit board (PCB) side down, on  
an antistatic work surface pad.  
Hold the adapter only by its sides or cover plate. Do not touch any  
components on the printed circuit board assembly (PCBA).  
Do not use any test equipment to check the components on the PCB.  
Do not bump, jar, or drop the adapter. Do not place other objects on  
top of the adapter.  
Transport the adapter in its shielded bag in an appropriate shipping  
container. Do not put other materials in the bag with the adapter.

Installing the A4800A Adapter  
Looking at Adapter Installation  
Look in g a t Ad a p ter In sta lla tion  
NOTE  
The host bus adapter card is supported on the HP N4000 N-class system.  
Refer to the Hewlett-Packard eproducts web site  
(http://www.eproducts.hp.com) to disassemble the system, install the  
adapter in an available PCI slot, and reassemble the system.  
Installation can be performed in one of two ways:  
Use the OLAR (On Line Add/Replace) capability (HP-UX 11i)  
Power down the system and then add or replace the HBA  
The method you choose will depend on your situation and requirements.  
In sta ll Usin g OLAR (HP -UX 11i)  
The letters O, L, A and R stand for On Line Addition [and] Replacement.  
This refers to the ability of a PCI I/O card to be installed (replaced or  
added) in an HP-UX computer system designed to support this feature  
without the need for completely shutting down, then re-booting the  
system or adversely affecting other system components. The system  
hardware uses the per-slot power control combined with operating  
system support in HP-UX 11i to enable this feature.  
IMPORTANT  
Certain Classes” of hardware are not intended for access by users. At  
this time this includes V-Class and SuperDome systems. HP  
recommends that these systems only be opened by a qualified HP  
Engineer. Failure to observe this requirement can invalidate any support  
agreement or warranty to which the owner might otherwise be entitled.  
Im p or ta n t Ter m s a n d Con cep ts  
The addition or replacement of an OLAR-compatible card may be done in  
either one of two ways:  
1. Using the SAM utility.

In many cases, other interface cards and slots within the system are  
dependent upon the target card. For example:  
If the target card is a multiple-port card, suspending or deleting drivers  
for the target card slot also suspends individual drivers for the multiple  
hardware paths on that card).  
Chapter 2

Installing the A4800A Adapter  
Looking at Adapter Installation  
During a card replacement operation, SAM performs a Critical Resource  
Analysis, which checks all ports on the target card for critical resources  
that would be temporarily unavailable while the card is shut down.  
P la n n in g a n d P r ep a r a tion  
SAM will, generally, prevent you from performing OLAR procedures that  
would adversely affect other areas of the server. Refer to Configuring  
HP-UX For Peripherals, HP Part Number B2355-90698 for detailed  
information.  
Cr itica l Resou r ces Because power to the slot must be off when the old  
card is removed and the new card is inserted, the effects of shutting  
down the cards functions must be carefully considered.  
This is particularly important if there is no on-line failover or backup  
card to pick up those functions. For example:  
Which mass storage devices will be temporarily disconnected when  
the card 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 successfully completing if the resource 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 card is shut down.  
During an OLAR procedure, it is essential to check the targeted card for  
critical resources, as well as the effects of existing disk mirrors and other  
situations where a cards functions can be taken over by another card  
that will not be affected.  
Fortunately SAM performs a thorough critical resource analysis  
automatically, and presents options to you based on its findings. If you  
determine that critical resources will be affected by the procedure, you  
should replace the card when the server is off-line.  
If you must take action immediately, you can use radto attempt an  
on-line addition of a backup card and deletion of the target card.

Installing the A4800A Adapter  
Looking at Adapter Installation  
Ca r d Com p a tibility  
On -Lin e Ad d ition (OLA). When on-line adding an interface card, the  
first issue that must be resolved is whether the new card is compatible  
with the system. Each PCI slot provides a set amount of power. The  
replacement card cannot require more power than is available.  
The card must also operate at the slots bus frequency. A PCI card must  
run at any frequency lower than its maximum capability; however, a  
card that operated at a maximum of 33 MHz would not work on a bus  
running at 66 MHz. radprovides information about the bus frequency  
and power available at a slot, as well as other slot-related data.  
On -Lin e Rep la cem en t (OLR) When on-line replacing an interface  
card, the replacement card must be identical to the card being replaced  
or at least be able to operate using the same driver as the replaced card.  
This is referred to as like-for-like replacement and should be adhered to  
because using a similar but not identical card may cause unpredictable  
results. For example, a newer version of the target card which is  
identical in terms of hardware may contain an updated firmware version  
that could potentially conflict with the current driver.  
The PCI specification allows a single physical card to contain more than  
one port. A single-port SCSI bus adapter can not be replaced by a  
dual-port adapter, even if the additional port(s) on the card are identical  
to the original SCSI bus adapter.  
When the replacement card is added to the system, the appropriate  
driver for that card must be configured in the kernel before beginning  
the operation. SAM ensures the correct driver is present. (In most cases,  
the replacement card will be the same type as a card already in the  
system, and this requirement will be automatically met.) If you have any  
question about the drivers presence, or if you are not certain that the  
replacement card is identical to the existing card, you can use ioscan  
together with radto investigate.  
If the necessary driver is not present and the driver is a dynamically  
loadable kernel module (DLKM), you can load it manually. Refer to  
the section Dynamically Loadable Kernel Modules” in Chapter 2 of  
the document: Configuring HP-UX For Peripherals, HP Part Number  
B2355-90698 for more information.  
If the driver is static and not configured in the kernel, then the card  
cannot be On-line Added. The card could be physically inserted  
on-line, but no driver would claim it.

OLA/R Restr iction s for th e A4800A  
The HBA has some restrictions in the OLA/R procedure. These  
restrictions are explained below.  
The restrictions are necessary because the SCSI attributes of initiator  
ID, and speed cannot be changed online for this HBA.  
OLA of A4800-60001 The HBA can be online added only if the SCSI  
attribute values of initiator IDand speedare usable in your  
configuration. These values will be set to the current PDC (Processor  
Dependent Code) values (if any) or default to the new HBA’s values (see  
Table 2-2).

In sta ll/Rep la ce With System Pow er ed Dow n  
Check the manual supplied with the server to perform the following  
installation:  
Step 1. Shut down the operating system.  
Step 2. Power off the system and disconnect the power cord and cables.  
Step 3. Access the back of the server cabinet following the instructions in the  
server documentation. Refer to the server documentation for instructions  
on disassembling the server and installing host bus adapters.  
22  
Chapter 2  
 
Installing the A4800A Adapter  
Looking at Adapter Installation  
Step 4. Locate the card separator/extractor slot where you intend to install the  
adapter.  
Step 5. Remove the blank panel aligned with the PCI slot you intend to use. If  
the blank panel has a bracket screw, save it for reuse during the  
installation.  
Step 6. Following the instructions in the server manual, insert the adapter into  
an available PCI slot.  
The adapter is keyed to be inserted in only one way. The components on  
the adapter may face the opposite way from other boards on the system.  
NOTE  
If the internal bus is not connected to any peripherals it MUST be  
terminated using the supplied low profile, internal terminator.  
Step 7. Verify that the connectors on the adapter and the bus converter are  
aligned properly and firmly seated. The cards bracket should fit where  
the blank panel was removed. Secure the bracket with the bracket screw  
from the blank panel, if there is one. Note that, for N-Class systems, a  
screw is not used to secure the card.  
NOTE  
NOTE  
If the adapter will only be used with internal SCSI devices, install the  
A4700-67098 (1252-6520) differential terminator into the external port.  
Step 8. Connect peripheral devices and terminate the SCSI bus.  
A cable for connecting the PCI Ultra SCSI Host Bus Adapter to a disk  
tray A or B port connector is supplied with the A5068A product. Cables  
for connecting external devices are not supplied with the controller and  
must be purchased separately.  
Step 9. Set the SCSI ID, if needed.  
The default SCSI ID is 7. To change this to a different value for  
High-Availability (HA) applications, you must use the Boot Console  
Handler (BCH). There are no SCSI address switches or jumpers. You

must invoke the appropriate commands in the SCSI section of the BCH  
and change the address electronically to whatever is required for the HA  
configuration being used. Refer to Checking SCSI Bus Compatibility” on  
page 36.  
NOTE  
Do not change for MPE/iX. You may need to change "rate" setting.  
Step 10. Reassemble the server.  
Step 11. Power on the system and reboot the operating system.  
Step 12. The A4800A adapter runs an automatic self test. Error messages, if any  
are generated, appear on the system console.

Installing the A4800A Adapter  
Terminating the A4800A Adapter  
Ter m in a tin g th e A4800A Ad a p ter  
The A4800A has no auto-termination setting. Termination must be  
provided by a physical terminator. When the HBA is at the end of the  
SCSI bus, the terminator should be installed and secured at either the  
internal or external connector (whichever does not have a cable attached)  
as shown in Figure 1-1 on page 8.  
When the adapter is used in High-Availability (HA) applications (such as  
MC/ServiceGuard) and it is required to be in the middle of the bus, the  
adapters terminator must be removed.  
The SCSI bus must be properly terminated. Terminators may be ordered  
separately if needed (When ordered with the HBA, the part number is  
A4800A option 2. When ordered separately, the part number is C2905A).  
The first and last physical SCSI devices connected on the ends of the  
SCSI bus must have terminators attached. All other SCSI devices on the  
SCSI bus must have their terminators removed or disabled. Note that  
the host bus adapter is also on the bus.  
IMPORTANT  
NOTE  
The A4800A does not provide automatic termination.  
When the adapter is used in HA applications that use two SCSI host bus  
adapters (such as MC/ServiceGuard) and it is required to be in the  
middle of the bus, the adapters SCSI ID will need to be changed (for  
example, from 7to 6). Each device on the bus must have a unique ID.  
Refer to The SCSI Command” on page 37.  
To disable the adapters termination, you need to physically remove the  
terminator from the HBA connector. Termination for this bus must now  
be provided by some other SCSI device (e.g. disk, disk array, or other  
HBA, as required).

Chapter 2  
 
 
Installing the A4800A Adapter  
Setting SCSI IDs  
Settin g SCSI IDs  
You must assign a separate SCSI ID (0 through 15 for a 16-bit SCSI bus)  
to the SCSI host bus adapter 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, we recommend you to give the SCSI  
host bus adapter higher priority than the other SCSI devices on the bus.  
SCSI ID 7 is the preset SCSI ID for the A4800A SCSI host bus adapter  
(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.  
For a multi-initiator (High Availability [HA]) configuration, where  
multiple SCSI host bus adapters are connected to the same SCSI bus, the  
SCSI host bus adapter that carries most of the traffic must be assigned a  
SCSI ID of 7 (giving it the highest priority). Later, you must change the  
SCSI ID of each of the remaining SCSI host bus adapters 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 host bus adapter (SCSI ID = 7), the hard disk  
bus adapters, the hard disk drive would be assigned the next highest  
priority SCSI ID available after all of the SCSI host bus adapters have  
been assigned higher priority SCSI IDs.  
To change the SCSI ID of the A4800A host bus adapter, refer to  
Checking SCSI Bus Compatibility” on page 36.  
The peripheral device SCSI IDs are usually set with jumpers or a switch  
on the peripheral. Refer to the peripheral manufacturers instructions to  
determine the ID of each device and how to change it.  
IMPORTANT  
Chapter 2  
You must not have duplicate SCSI IDs on a SCSI bus; the system will  
hang or crash if you have duplicate SCSI IDs on the bus.

Troubleshooting  
General Procedure  
Gen er a l P r oced u r e  
The A4800A adapter is a single field-replaceable unit (FRU) and does not  
contain any field-serviceable parts. Troubleshooting procedures  
described in this section are limited to verifying that the adapter is  
operational and a valid connection is established.  
In general, follow these steps to troubleshoot the A4800A adapter:  
Step 1. Check the connection.  
Make sure that the correct cable is used, connected, and operating  
properly and that there are no bent pins in any of the connectors.  
Step 2. Check SCSI bus compatibility.  
Ensure transfer rate compatibility with the attached devices using the  
SCSI boot menu command.  
Step 3. Check the adapter.  
Inspect the adapter to make sure it is seated properly in the PCI bus slot.  
If necessary, power down the system, reseat the adapter, and restart the  
system.  
Step 4. Run diagnostics.  
If a visual inspection of the adapter and cable(s) does not reveal any  
problems, or if an action taken as a result of the inspection does not  
produce a working adapter, you may want to run diagnostics to  
determine whether the adapter can communicate and respond to PCI  
bus instructions. Diagnostics are described in the next section.  
If diagnostics determine that the controller is defective, you must replace  
it. Contact your local Hewlett-Packard customer representative or call  
the HP Response Center.

Troubleshooting  
Checking SCSI Bus Compatibility  
Ch eck in g SCSI Bu s Com p a tibility  
You can ensure SCSI controller and SCSI device compatibility by using  
the SCSIcommand to display and select SCSI bus parameters.  
The SCSIcommand is available from the boot menu displayed after the  
test station has booted (if autoboot is disabled). The boot menu looks like  
this (for highlighting reasons, the SCSIcommand is in bold here):

Troubleshooting  
Checking SCSI Bus Compatibility  
Th e SCSI Com m a n d  
As explained above, you can use the SCSIcommand to check the  
compatibility of the SCSI adapter and the SCSI device(s), by displaying  
and setting SCSI bus parameters.  
NOTE  
See HP e3000 Communicator for MPE/iX release 7.0” for MPE/iX  
Disp la yin g Tr a n sfer Ra tes  
To use the SCSIcommand to display the SCSI transfer rate for an  
adapter, follow this syntax:  
SCSI rate bus_number slot_number  
where  
bus_number  
Specifies the number of the bus the adapter is installed  
on.  
slot_number  
Specifies the number of the slot the adapter is in.  
For example:  
To display the SCSI transfer rate for the adapter installed on bus 5  
slot 2, issue this command:  
SCSI rate 5 2  
The output could look something like this:  
PCI device /5.2 = no limit  
To list transfer rates for all bus and slot numbers, issue this  
command:  
SCSI rate

If the equipment is covered by an HP service contract, document the  
problem as a service request and forward it to your HP representative.  
Include the following information where applicable:  
Describe the problem, including the events and symptoms leading up  
to the problem. Attempt to describe the source of the problem.  
Include HP-UX or MPE/iX commands, communication subsystem  
commands, functionality of user programs, result codes and  
messages, and data that can reproduce the problem.  
Obtain the version, update, and fix information for all software.  
1. To check the version of the kernel, enter this command:  
uname -r  
To check patches, enter:  
what /stand/vmunix | grep scsi  
2. To check the version of MPE/iX enter: SHOWME  
To check patches, enter: PRINT HPSWINFO.PUB.SYS  
This allows HP to determine if the problem is already known and the  
correct software is installed at your site.  
Illustrate as clearly as possible the context of any messages. Record  
all error messages and numbers that appear at the user terminal  
and the system console.  
Prepare the formatted output and a copy of the log file for the HP  
representative to analyze.  
Prepare a listing of the HP-UX or MPE/iX I/O configuration being  
used for the HP representative to analyze.  
Try to determine the general area within the software where the  
problem may exist. Refer to the appropriate reference manual and  
follow the guidelines on gathering information for that product.

Troubleshooting  
Contacting Your Hewlett-Packard Representative  
Document your interim (workaround) solution. The cause of the  
problem can sometimes be found by comparing the circumstances in  
which the problem occurs with the circumstances in which the  
problem does not occur.  
In the event of a system failure, obtain a full memory dump.  
For HP-UX: If the directory /var/adm/crashexists, the HP-UX  
utility /sbin/savecoreautomatically executes during reboot to save  
the memory dump. HP recommends that you create the  
/tmp/syscoredirectory after successfully installing this product.  
Send the output of the system failure memory dump to the HP  
representative.  
For MPE/iX: If you use AUTORESTART and DUMPTODISK  
products follow your normal system recovery steps. Otherwise take a  
memory dump and save the resulting tape. Contact HP Support for  
analysis of your failure.  
If the equipment is not covered by an HP service contract, there may be a  
charge for time and materials.

in the error message text. Each Additional sense and its corresponding  
Qualifier code—shown in bold in the example above—require  
interpretation on your part. Use the two codes together to determine the  
meaning. In the example above, the Additional sense (0x18) and  
Qualifier (0x01) codes together mean recovered data with error  
correction and retries applied.” You can look up the various codes and  
keys in the tables on the next pages.
