    • Install the A6829A adapter in a PCI4X 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).

    (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.

    NOTE As stated earlier, although the A6829A 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. Also, we recommend using a PCI4X slot, to get maximum performance. However, you can install the adapter in a PCI2X, PCI1X, or shared PCI slot, if necessary.

  • Page 31: Table 2-1 Important Olar Terms

    Installing the A6829A Adapter Installing the A6829A 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.

    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.

  • Page 98: Domain Validation

    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 A6829A). See “Maximum Data Transfer Rate” on page 45 for more information on setting the HBA’s transfer rate.
  • Page 99 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.log file: SCSI:Ultra160 SCSI Adapter at hw_path : fallback occurred for...

We are providing it here to give you an example of how the fallback procedure works.
  • Page 101 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...

    STM is a software application that can be run from the console to obtain status and descriptive information about the A6829A adapter, diagnose problems, and update firmware. For the A6829A adapter, you must use STM version A.29.00 or later. See the Support Tools Manager User’s Guide for more details about STM.
