Installing the A4800A Adapter 14 • “Connecting to External SCSI Devices” on page 16. • “Handling the A4800A Adapter” on page 17. • “Looking at Adapter Installation” on page 18. • “Connecting SCSI Peripheral Devices” on page 25. • “Terminating the A4800A Adapter” on page 28 • “Setting SCSI IDs” on page 29 • “Verifying Installation” on page 31.
Installing the A4800A Adapter Preparing for Installation 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: Chapter 2 ✓ One HP A4800A SCSI adapter. ✓ One grounding (ESD) wrist strap.
Installing the A4800A Adapter Connecting to External SCSI Devices 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.
Installing the A4800A Adapter Handling 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.

For detailed information about the use of either of these two procedures, please refer to the following document: Configuring HP-UX For Peripherals, HP Part Number B2355-90698 This document may be ordered from HP, or you may view, download and print it from the following website: www.docs.hp.
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.
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.
Installing the A4800A Adapter Looking at Adapter Installation 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.
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.
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.
Installing the A4800A Adapter Connecting SCSI Peripheral Devices 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.
Installing the A4800A Adapter Connecting SCSI Peripheral Devices You can connect up to four devices if they are evenly spaced on a 3 m Ultra SCSI cable (0.75 m between devices). The single-ended SCSI bus must not exceed 3 m (total internal and external cable lengths) even with fewer than four devices. Table 2-4 below shows the maximum bus length for each of the SCSI types.

(2)Single-ended and High Voltage Differential are not defined at Ultra2 speeds.
Installing the A4800A Adapter Terminating 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.
Installing the A4800A Adapter Setting SCSI IDs 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.
Installing the A4800A Adapter Setting SCSI IDs Make necessary changes, if any, to the SCSI IDs and record the IDs for future reference. To keep a record of the IDs, you can use Table 2-5.
Installing the A4800A Adapter Verifying Installation Verifying Installation After installing the adapter and attaching peripheral devices, verify that all components are working. Refer to your system documentation for information on verifying operation. HP 9000 Step 1.
Installing the A4800A Adapter Verifying Installation HP e3000 Assuming an N-Class system with an I/O card being added to slot #12, we will expect path 1/0/0/0 to be returned for our card. Step 1. From BCH menus: ------------------------------------------------------Command ------ALL ... IO ...
3 Troubleshooting This chapter contains the following sections that describe how to troubleshooting the A4800A adapter: • Chapter 3 “General Procedure” on page 35.
Troubleshooting 34 • “Checking SCSI Bus Compatibility” on page 36. • “Using Support Tools Manager (STM)” on page 41 • “Contacting Your Hewlett-Packard Representative” on page 42.
Troubleshooting General Procedure 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.
Troubleshooting Checking SCSI Bus Compatibility 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).
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.
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 Specifies the number of the slot the adapter is in.
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.
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 Specifies the number of the slot the adapter is in. ID_num Specifies the adapter’s SCSI ID number.
Troubleshooting Using Support Tools Manager (STM) 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.
Troubleshooting Contacting Your Hewlett-Packard Representative 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.
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.
