Installing the A4800A Adapter

Preparing for Installation

Installing the host bus adapter requires disassembly of some server components. Before beginning installation, see the HP 9000 system manual for detailed instructions about how to install host bus adapters in the PCI slots.

You will need the following things:

✓ One HP A4800A SCSI adapter. ✓ One grounding (ESD) wrist strap. ✓ Any other tools needed for installing components in the HP 9000 or

HP e3000 system (for example, screwdrivers); see the system’s documentation.

Chapter 2 15

Installing the A4800A Adapter

Connecting to External SCSI Devices

If you intend to connect the PCI Ultra SCSI adapter to an external SCSI device, you need to supply a differential SCSI cable that is long enough to reach the device. Part numbers for several different cable lengths are listed in the section titled “Cable Speciﬁcations” on page 11.

Chapter 216

Installing the A4800A Adapter

Handling the A4800A Adapter

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.

Chapter 2 17

Installing the A4800A Adapter

Looking at Adapter Installation

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.

Install Using 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. Failureto observe this requirement can invalidate any support agreement or warranty to which the owner might otherwise be entitled.

Important Terms and Concepts

The addition or replacement of an OLAR-compatible card may be done in either one of two ways:

1. Using the SAM utility.

Chapter 218

2. Issuing command-line commands using rad.

For detailed information about the use of either of these two procedures, please refer to the following document:

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.

Planning and Preparation

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.

Critical Resources 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 card’s 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 card’s 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 rad to attempt an on-line addition of a backup card and deletion of the target card.

Chapter 220

Installing the A4800A Adapter

Looking at Adapter Installation

Card Compatibility On-Line Addition (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 slot’s 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. rad provides information about the bus frequency and power available at a slot, as well as other slot-related data.

On-Line Replacement (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 driver’s presence, or if you are not certain that the replacement card is identical to the existing card, you can use ioscan together with rad to 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 ForPeripherals,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 Restrictions for the 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 ID and speed are 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).

Table 2-2 A4800-60001 - Default SCSI Attribute Values

Attribute Default Value

Initiator ID 7 Speed Fast

If these attributes are not acceptable, you must reboot the system to access the Boot Console Handler (BCH) prompt and then change the values in the PDC.

OLR of A4800-60001 the A4800-60001 can be Online Replaced without special considerations. See the Conﬁguring HP-UX Peripherals manual for the steps that are necessary to OLR this HBA.

Install/Replace With System Powered Down

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.

Chapter 222

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 card’s 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 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.

NOTE 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

Chapter 2 23

Installing the A4800A Adapter

Looking at Adapter Installation

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.

Chapter 224

Connecting SCSI Peripheral Devices

Connect multiple SCSI devices by chaining them together with shielded, 68-pin, High-Density (HD) cables. The connectors on these cables are keyed to ensure proper pin-1 to pin-1 registration. Refer to the peripheral manual for instructions on attaching SCSI cables. Peripheral storage devices are normally shipped with the required SCSI cables.

Chapter 2 27

Installing the A4800A Adapter

Terminating the A4800A Adapter

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 adapter’s terminator must be removed.

The SCSI bus must be properly terminated. Terminatorsmay 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 The A4800A does not provide automatic termination.

NOTE 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 adapter’s SCSI ID will need to be changed (for example, from 7 to 6). Each device on the bus must have a unique ID. Refer to “The SCSI Command” on page 37.

To disable the adapter’s 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 228

Installing the A4800A Adapter

Setting 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 drive would be assigned a SCSI ID of 6. If there are multiple SCSI host 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 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 will

hang or crash if you have duplicate SCSI IDs on the bus.

Chapter 2 29

3 Troubleshooting

This chapter contains the following sections that describe how to troubleshooting the A4800A adapter:

• “General Procedure” on page 35.

Chapter 3 33

Troubleshooting

• “Checking SCSI Bus Compatibility” on page 36.

• “Using Support Tools Manager (STM)” on page 41

• “Contacting Your Hewlett-Packard Representative” on page 42.

Chapter 334

General Procedure

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.

Troubleshooting

General Procedure

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.

Chapter 3 35

Troubleshooting

Checking SCSI Bus Compatibility

You can ensure SCSI controller and SCSI device compatibility by using the SCSI command to display and select SCSI bus parameters.

The SCSI command 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 SCSI command is in bold here):

Command Description

Chapter 336

Troubleshooting

Checking SCSI Bus Compatibility

The SCSI Command

As explained above, you can use the SCSI command 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

guidelines on rate. http://docs.hp.com/mpeix/pdf/30216-90312.pdf

Displaying Transfer Rates

To use the SCSI command 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

Chapter 3 37

Troubleshooting

Checking SCSI Bus Compatibility

Setting Transfer Rates

To use the SCSI command to set the SCSI transfer rate for an adapter, follow this syntax:

SCSI rate

bus_number slot_number rate

where

bus_number

Speciﬁes the number of the bus the adapter is installed on.

slot_number rate

Speciﬁes the number of the slot the adapter is in. Speciﬁes the adapter’s transfer rate:

• 0 (no limit)

• 10 (Fast SCSI)

• 20 (Ultra SCSI)

For example, to set the SCSI transfer rate for the adapter installed on bus 5 slot 2 to Fast SCSI and then display the results, issue these commands:

SCSI rate 5 2 10

SCSI rate 5 2

The output (of the second command) could look something like this:

PCI device /5.2 = fast SCSI

Chapter 338

Troubleshooting

Checking SCSI Bus Compatibility

Displaying SCSI IDs

To use the SCSI command to display the initiator (SCSI) IDs for an adapter, follow this syntax:

SCSI init

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 ID for the adapter on bus 5 slot 2, issue this command:

SCSI init 5 2

The output could look something like this:

PCI device /5.2 = 7

• To list the SCSI IDs for all bus and slot numbers, issue this command:

SCSI init

Chapter 3 39

Troubleshooting

Checking SCSI Bus Compatibility

Setting SCSI IDs

To use the SCSI command to set the initiator (SCSI) ID for an adapter, follow this syntax:

SCSI init

bus_number slot_number ID_number

where

bus_number

Speciﬁes the number of the bus the adapter is installed on.

slot_number ID_num

Speciﬁes the number of the slot the adapter is in. Speciﬁes the adapter’s SCSI ID number.

For example, to set the SCSI ID for the adapter installed on bus 5 slot 2 to 6 and then display the results, issue these commands:

SCSI init 5 2 6

SCSI init 5 2

The output (of the second command) could look something like this:

PCI device /5.2 = 6

Chapter 340

Troubleshooting

Using Support Tools Manager (STM)

STM is a software application that can be run from the console to obtain status and descriptive information about the A4800A adapter, diagnose problems, and update ﬁrmware. See the Support Tools Manager User’s Guide for more details about STM.

Chapter 3 41

Troubleshooting

Contacting Your Hewlett-Packard Representative

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.

Chapter 342

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/crash exists, the HP-UX utility /sbin/savecore automatically executes during reboot to save the memory dump. HP recommends that you create the /tmp/syscore directory 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.

A SCSI Sense Codes

This appendix shows the possible codes that appear in SCSI error messages.

Appendix A 45

SCSI Sense Codes

HP 9000 The following example shows a typical SCSI error message:

[+6708 72410001 002a9858 0:7] scsi disk: CHECK CONDITION on disk 0:6:5:0 Read of logical block 509856, count 128 disk sd45a, block 254920, 65536 bytes Valid = 1, Error code = 0x70 Segment number = 0x00, Filemark = 0, EOM = 0, ILI = 0

Sense key = 0x1, "RECOVERED ERROR"

Information = 0x00 0x07 0xc7 0xe4 [+6709 72410001 002a9a10 0:7] scsi disk: Additional sense length = 0x0a Command-specific information = 0x00 0x00 0x00 0x00

Additional sense = 0x18, Qualifier = 0x01

Field replaceable unit code = 0xea SKSV = 1, C/D = 0, BPV = 0, Bit pointer = 0 Field pointer = 0x0003

The status (CHECK CONDITION) and sense key (RECOVERED ERROR)—shown in bold in the example above—are interpreted for you 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.

MPE/iX Use the CSTM tool to look at hardware error information. Information

about CSTM can be found in the article “TERMDSM: User Interface Change undre System Diagnostics” in the “Communicator 3000 MPE/iX Release 6.5”. http://docs.hp.com/mpeix/pdf/30216-90291.pdf
