  2. Type iprconfig on the command line of the Linux(R) session and press Enter.

    The IBM(R) Power RAID Configuration Utility display is shown.

  3. Select Analyze log. Press Enter. The Kernel Messages Log display is shown.
    Figure 20. Kernel Messages Log 
                                          Kernel Messages Log


Select one of the following:

    1. View most recent ipr error messages
    2. View ipr error messages
    3. View all kernel error messages
    4. View iprconfig error messages
    5. Set root kernel message log directory
    6. Set default editor
    7. Restore defaults
    8. View ipr boot time messages


Selection:

e=Exit
  4. Select View most recent ipr error messages from the Kernel Messages Log display. Press Enter.
  5. Find the entry in the log for the disk drive you want to replace.
  6. Record the location information for the disk drive.
    Note:
    The location information has the form of 2:0:8:0. In this example, 2 is the SCSI host number, 0 is the SCSI bus, 8 is the SCSI target ID, and 0 is the LUN (logical unit).
  7. Return to the command line.
  8. Type the following:

    ls -ld /sys/class/scsi_host/host#/device

    where # is the SCSI host number. Press Enter.

  9. Record the PCI location information.
    Note:
    The PCI location information has the form of 61:01:0:2.
  10. Type iprconfig on the command line and press Enter.

    The IBM Power RAID Configuration Utility display is shown.

  11. Select Display hardware status from the IBM Power RAID Configuration Utility display. Press Enter.

    The Display Hardware Status display is shown.

  12. Look for the disk drive at the PCI location you recorded. The disk drive might have a Failed status.
  13. If the disk drive you want to replace is unprotected or in use, move the data from the disk drive before continuing with this procedure.

    For information, see the PCI-X SCSI RAID Controller Reference Guide for Linux.
