MAP 3111

Use this MAP to resolve the following problems:
  • Two or more disks are missing from a RAID 5 or RAID 6 disk array (service request number (SRN) nnnn-9020, nnnn-9021, or nnnn-9022) for a PCI-X or PCIe controller.
  • One or more disk pairs are missing from a RAID 10 disk array (SRN nnnn-9060) for a PCI-X or PCIe controller.
  • One or more disks are missing from a RAID 0 disk array (SRN nnnn-9061, nnnn-9062) for a PCI-X or PCIe controller.

Step 3111-1

Identify the disks missing from the disk array by examining the hardware error log. The hardware error log can be viewed as follows:

  1. Follow the steps in Examining the hardware error log and return here.
  2. Select the hardware error log to view. Viewing the hardware error log, the missing disks are those listed under Array Member Information with an Actual Resource of *unkwn*.
  3. Go to Step 3111-2.

Step 3111-2

Perform only one of the following options, listed in the order of preference:

Option 1
Locate the identified disks and install them in the correct physical locations (that is, the Expected Resource field) in the system. See SAS resource locations to understand how to locate a disk by using the Expected Resource field.

After installing the disks in the locations shown in the Expected Resource field, complete only one of the following options:

  • Run diagnostics in system verification mode on the adapter:
    1. Start AIX diagnostics and select Task Selection on the Function Selection display.
    2. Select Run Diagnostics.
    3. Select the adapter resource.
    4. Select System Verification.
  • Unconfigure and reconfigure the adapter by performing the following steps:
    1. Unconfigure the adapter.
      1. Start the IBM® SAS Disk Array Manager.
        1. Start AIX diagnostics and select Task Selection on the Function Selection display.
        2. Select RAID Array Manager > IBM SAS Disk Array Manager.
      2. Select Diagnostics and Recovery Options > Unconfigure an Available IBM SAS RAID Controller.
    2. Configure the adapter.
      1. Start the IBM SAS Disk Array Manager.
        1. Start AIX diagnostics and select Task Selection on the Function Selection display.
        2. Select RAID Array Manager > IBM SAS Disk Array Manager.
      2. Select Diagnostics and Recovery Options > Configure a Defined IBM SAS RAID Controller.
  • Perform an IPL of the system or logical partition.

When the problem is resolved, see the removal and replacement procedures topic for the system unit on which you are working and do the "Verifying the repair" procedure.

Option 2
Delete the disk array, as follows:
Attention: All data on the disk array will be lost.
  1. Start the IBM SAS Disk Array Manager.
    1. Start AIX diagnostics and select Task Selection on the Function Selection display.
    2. Select RAID Array Manager > IBM SAS Disk Array Manager.
  2. Select Delete a SAS Disk Array > IBM SAS RAID Controller.
  3. Select the disk array to delete.

When the problem is resolved, see the removal and replacement procedures topic for the system unit on which you are working and do the "Verifying the repair" procedure.

Option 3
Format the remaining members of the disk array, as follows:
Attention: All data on the disk array will be lost.
  1. Start the IBM SAS Disk Array Manager.
    1. Start AIX Diagnostics and select Task Selection on the Function Selection display.
    2. Select RAID Array Manager > IBM SAS Disk Array Manager.
  2. Select Diagnostics and Recovery Options > Format Physical Disk Media (pdisk).

When the problem is resolved, see the removal and replacement procedures topic for the system unit on which you are working and do the "Verifying the repair" procedure.
