MAP 3134

Use this MAP to resolve the following problem: Disk requires Format before use (SRN nnnn-9092) for a PCI-X or PCIe controller

The possible causes follow:

  • Disk is a previously failed disk from a disk array and was automatically replaced by a hot spare disk.
  • Disk is a previously failed disk from a disk array and was removed and later reinstalled on a different adapter or different location on this adapter.
  • Appropriate service procedures were not followed when replacing disks or reconfiguring the adapter, such as not using the SCSI and SCSI RAID Hot Plug Manager when concurrently removing or installing disks, or not performing a normal power off of the system prior to reconfiguring disks and adapters.
  • Disk is a member of a disk array, but was detected subsequent to the adapter being configured.
  • Disk has multiple or complex configuration problems.

Step 3134-1

Identify the affected disks by examining the hardware error log. The hardware error log might 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 Device Errors Detected field indicates the total number of disks that are affected. The Device Errors Logged field indicates the number of disks for which detailed information is provided. Under the Original Device heading, the Resource, Vendor/Product ID, S/N, and World Wide ID are provided for up to three disks. Additionally, the Original Controller Type, S/N, and World Wide ID for each of these disks indicates the adapter to which the disk was last attached when it was operational. Refer to SAS resource locations to understand how to locate a disk using the Resource field.

  3. Go to Step 3134-2.

Step 3134-2

Are there other disk or adapter errors that have occurred at about the same time as this error?

No
Go to Step 3134-3.
Yes
Go to Step 3134-5.

Step 3134-3

Have the adapter card or disks been physically moved recently?

No
Go to Step 3134-4.
Yes
Go to Step 3134-6.

Step 3134-4

Is the data on the disks needed for this or any other system?

No
Go to Step 3134-7.
Yes
Go to Step 3134-6.

Step 3134-5

Take action on the other errors that have occurred at the same time as this error.

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.

Step 3134-6

Perform only one of the following options that is most applicable to your situation:

Option 1

Perform only one of the following to cause the adapter to rediscover the disks and then take action on any new errors:

  • 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 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 on the system or logical partition

Take action on any other errors which are now occurring.

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

Restore the adapter and disks to their original configuration. Once this has been done, 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 3

Remove the disks from this adapter.

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.

Step 3134-7

Perform only one of the following options.

Option 1
If the disks are members of a disk array, delete the disk array by doing the following steps:
Attention: All data on the disk array will be lost.
Note: In some rare scenarios, deleting the disk array will not have any effect on a disk and the disk must be formatted instead.
  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 2
Do the following to format the disks:
Attention: All data on the disks 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.
