2 Installing the A6828A Adapter This chapter contains the following sections that describe how to install the A6828A adapter: • Chapter 2 “Overview of Installation Steps” on page 9 7
Installing the A6828A Adapter NOTE 8 • “Performance Tuning” on page 11 • “Preparing for Installation” on page 12 • “Installing the A6828A Adapter” on page 13 • “Connecting External SCSI Peripherals” on page 19 • “Specifying SCSI Parameters” on page 21 • “Installing the SCSI Driver” on page 50 • “Configuring LUN 0” on page 52 • “Adding Multi-Initiator Support” on page 53 • “Verifying Installation” on page 55 • “Using the Extended Firmware Interface Flash Utility” on page 58 This manual
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).
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_qdepth kernel tunable parameter: — HP-UX 11.0: scsi_max_qdepth is 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.
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.
Installing the A6828A Adapter Installing the A6828A Adapter Installing the A6828A Adapter This section contains information on installing the A6828A HBA in an HP-UX system (including Online Addition and Replacement [OLAR]). WARNING 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.
Installing the A6828A Adapter Installing the A6828A Adapter 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 64-bit PCI slot. In addition, HP recommends using a PCI4X or PCI2X slot, to get maximum performance. However, you can install the adapter in a PCI2X, PCI1X, or shared PCI slot, if necessary.
Installing the A6828A Adapter Installing the A6828A Adapter HP recommends that you use SAM instead of the rad command 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.
Installing the A6828A 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.
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.
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.
Installing the A6828A Adapter 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.
Installing the A6828A Adapter Connecting External SCSI Peripherals Figure 2-1 below is a drawing (not to scale) of a typical SCSI shielded 68-pin LVD cable. Figure 2-1 SCSI Cable for External Connections Shielded external High Density 68-pin SCSI LVD cable 68-pin HD (connect to external SCSI device) 68-pin VHDCI (connect to adapter) To connect external SCSI devices to the A6828A adapter, perform the following steps: Step 1.
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: NOTE • SCSI ID (SCSI initiator ID)—see “SCSI IDs” on page 25. • 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.

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.
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 Table 2-3.
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.
Installing the A6828A Adapter Specifying SCSI Parameters 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.

Installing the A6828A Adapter Specifying SCSI Parameters NOTE If you set a particular maximum data transfer rate to the SCSI controller (in this example, 53C1010-66), then the same maximum data transfer rate is set to all the devices. This happens because all the devices are connected to the same SCSI bus, which is controlled by the SCSI controller. Step 6. After making the necessary changes, press the [ESC] key to exit the Device Properties screen. This takes you back to the Adapter Properties screen.
Installing the A6828A Adapter Specifying SCSI Parameters Step 9. At the EFI shell prompt, issue the following command to reboot the system: reset NOTE 36 The system reboot is required for the new setting to take effect.
Installing the A6828A Adapter Specifying SCSI Parameters Auto Termination 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 can visit HP IT Resource Center (ITRC) at http://itrc.hp.com.
Installing the A6828A Adapter Specifying SCSI Parameters Table 2-4 Summary of A6828A Auto Termination Configurations Jumper Position Auto Termination Feature Termination Applied on Adapter 1An 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).
Installing the A6828A Adapter Specifying SCSI Parameters 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: TIP • 8 bits (Narrow) • 16 bits (Wide) 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.
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.

Installing the A6828A Adapter 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.
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 c8xx driver, which is used by the A6828A HBA in all the supported HP-UX systems.
Installing the A6828A Adapter Installing the SCSI Driver 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 swlist command to ensure that the necessary patches and the c8xx driver are present. Step 5. Check to see if the c8xx driver is loaded in the kernel by doing one of the following two things: • Use SAM, as follows: 1.
Installing the A6828A Adapter 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).
Installing the A6828A Adapter Adding Multi-Initiator Support Adding Multi-Initiator Support In a multi-initiator configuration, multiple SCSI host bus adapters (HBA) are connected to the same SCSI bus. Multi-initiator is supported for A6828A HBAs having part number A6828A-60101 or higher. NOTE Multi-initiator is not supported for HP A6828A SCSI HBA with part number A6828A-60001.
Installing the A6828A Adapter Adding Multi-Initiator Support Multi-Initiator Support for Itanium-Based System If you need multi-initiator support for HP A6828A SCSI HBA installed in an Itanium-based system, perform the following steps: Step 1. Ensure that the part number of the HBA is A6828A-60101. Step 2. Install the driver patch, PHKL_28566.
Installing the A6828A Adapter Verifying Installation Verifying Installation After installing the adapter and the c8xx driver and attaching the peripheral devices, verify that all the components are working by performing the following steps: Step 1.
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: — This is not the actual transfer rate, but the maximum transfer 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).
Installing the A6828A Adapter Verifying Installation TIP When the system boots after installation, the insf command 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.
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.
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.

3 Troubleshooting The A6828A adapter is a single field-replaceable unit (FRU) and does not contain any field-serviceable parts. Troubleshooting procedures described in this chapter are limited to verifying that the adapter is operational and a valid connection is established.
Troubleshooting This chapter contains the following sections that describe how to troubleshoot the A6828A adapter: 64 • “General Procedure” on page 65. • “NVRAM SCSI Parameters Do Not Match” on page 66. • “Creating Missing Device Files” on page 67. • “If the A6828A Adapter is Not Claimed” on page 68. • “Setting and Confirming SCSI Parameters” on page 70. • “Domain Validation” on page 80. • “Using Support Tools Manager (STM)” on page 85.
Troubleshooting 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.
Troubleshooting NVRAM SCSI Parameters Do Not Match NVRAM SCSI Parameters Do Not Match On hp servers rp7410, rp8400, and superdome only, you might see the following message after you have installed the A6828A adapter (it would be displayed at the BCH “Main Menu”): ERROR: PDH NVRAM and I/O card NVRAM SCSI parameters do not match for path hw_path Search aborted. The SCSI parameters for this card must be corrected from the BCH Service menu. To correct this problem, follow these steps: Step 1.
Troubleshooting Creating Missing Device Files Creating Missing Device Files When the system boots after installation, the insf command 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].
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 ioscan command), the most likely reason is that you installed the c8xx driver but did not install the required patches. To fix this problem, perform the following steps: Step 1.
Troubleshooting If the A6828A Adapter is Not Claimed Step 3. Load the c8xx driver 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.
Troubleshooting Setting and Confirming SCSI Parameters Setting and Confirming SCSI Parameters You can ensure compatibility between the SCSI controller and SCSI devices using the commands available for setting and displaying the appropriate SCSI bus parameters, including SCSI IDs. The procedure varies depending on which system the HP A6828A host bus adapter is installed in.
Troubleshooting Setting and Confirming SCSI Parameters Setting and Confirming SCSI Parameters for HP A6828A Host Bus Adapters Installed in PA-RISC Based Systems If the HP A6828A SCSI host bus adapter is installed in a supported PA-RISC based system, use the SCSI command to display and select SCSI parameters. The SCSI command is available from the boot menu displayed after the test station has booted (if autoboot is disabled).
Troubleshooting Setting and Confirming SCSI Parameters The SCSI Command The SCSI command can be used to display and set SCSI bus parameters to ensure that the SCSI adapter is compatible with the SCSI devices. Displaying Transfer Rates To display the SCSI transfer rate for an adapter using the SCSI command, use the following syntax: SCSI rate bus_number slot_number where bus_number Specifies the number of the bus on which the adapter is installed.
Troubleshooting Setting and Confirming SCSI Parameters Setting Transfer Rates To set the SCSI transfer rate for an adapter using the SCSI command, use the following syntax: SCSI rate bus_number slot_number rate where bus_number Specifies the number of the bus on which the adapter is installed. slot_number Specifies the number of the slot the adapter is in.
Troubleshooting Setting and Confirming SCSI Parameters Displaying SCSI IDs To display the initiator SCSI IDs for an adapter using the SCSI command, use the following syntax: SCSI init bus_number slot_number where bus_number Specifies the number of the bus on which the adapter is installed. slot_number Specifies the number of the slot the adapter is in.
Troubleshooting Setting and Confirming SCSI Parameters Setting SCSI ID To set the initiator SCSI ID for an adapter using the SCSI command, use the following syntax: SCSI init bus_number slot_number ID_number where bus_number Specifies the number of the bus on which the adapter is installed. slot_number Specifies the number of the slot the adapter is in. ID_num Specifies the adapter’s SCSI ID number.
Troubleshooting Setting and Confirming SCSI Parameters Setting and Confirming SCSI Parameters for HP A6828A Host Bus Adapter Installed in Itanium-Based Systems If the HP A6828A SCSI host bus adapter (HBA) is installed in a supported Itanium-based system, use the following procedure to display and select SCSI parameters: Step 1.
Troubleshooting Setting and Confirming SCSI Parameters Step 3. Find the controller handle designation, .

Troubleshooting Setting and Confirming SCSI Parameters Step 5. Press the [ESC] key to exit the Adapter Properties screen. If you did not modify any of the SCSI parameters, then the Global Properties screen appears. However, if you modified any of the SCSI parameters, then the following screen appears: Adapter and/or device property changes have been made.
Troubleshooting 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.
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.
Troubleshooting Domain Validation Table 3-1 Domain Validation Fallback Levels Bus Width Data Transfer Rate (MB/s) Ultra160 Wide 160 Ultra2 Wide Wide 80 Narrow 40 Wide 40 Narrow 20 Wide 20 Fast Narrow 10 Asynchronous Narrow <5 Type of SCSI Ultra2 Ultra Wide Ultra Fast Wide 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.
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.
Troubleshooting Domain Validation NOTE 84 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.
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 A6828A adapter, diagnose problems, and update firmware. For the A6828A adapter, you must use STM version A.29.00 or later. See the Support Tools Manager User’s Guide for more details about STM.
