MAP 3210

Use this MAP to resolve the following problems:

• Incompatible disk is installed at the degraded disk location in the disk array (SRN nnnn-9025) for PCIe2 or PCIe3 controllers.
• Disk array is degraded due to a missing or failed disk (SRN nnnn - 9030) for PCIe2 or PCIe3 controllers.
• Automatic reconstruction was initiated for a disk array (SRN nnnn - 9031) for PCIe2 or PCIe3 controllers.
• Disk array is degraded due to a missing or failed disk (SRN nnnn - 9032) for PCIe2 or PCIe3 controllers.

Step 3210-1

Identify the disk array by examining the hardware error log.

1. Follow the steps in Examining the hardware error log and return here.
2. Select the hardware error log to view. This error log displays the following disk array information under the heading Array Information:Resource, S/N (serial number), and RAID Level.
3. Go to Step 3210-2.

Step 3210-2

View the current disk array configuration as follows:

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 List SAS Disk Array Configuration.
3. Select the IBM SAS RAID controller that is identified in the hardware error log.
4. Go to Step Step 3210-3.

Step 3210-3

Does a disk array have a state of Degraded?

No

Go to Step 3210-4.

Yes

Go to Step 3210-5.

Step 3210-4

The affected disk array has a state of either Rebuilding or Optimal due to the use of a hot spare disk.

Identify the failed disk, which is no longer a part of the disk array, by finding the pdisk listed at the bottom of the display that has a state of either Failed or RWProtected. Using appropriate service procedures, such as use of the SCSI and SCSI RAID Hot Plug Manager, remove the failed disk and replace it with a new disk to use as a hot spare. See the Replacing pdisks section for this procedure, and then continue here.

Return to the List SAS Disk Array Configuration display in the IBM SAS Disk Array Manager. If the new disk is not listed as a pdisk, it might first need to be prepared for use in a disk array. Do the following steps:

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 Create an Array Candidate pdisk and Format to 528 Byte Sectors.
3. Select the appropriate IBM SAS RAID controller.
4. Select the disks from the list that you want to prepare for use in the disk arrays.

To make the new disk usable as a hot spare, complete the following steps:

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 Change/Show SAS pdisk Status > Create a Hot Spare.
3. Select the IBM SAS RAID controller.
4. Select the pdisk that you want to designate as a hot spare.

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 3210-5

Identify the failed disk by finding the pdisk listed for the degraded disk array that has a state of Failed. Using appropriate service procedures, such as the SCSI and SCSI RAID Hot Plug Manager, remove the failed disk and replace it with a new disk to use in the disk array. Refer to the Replacing pdisks section for this procedure, and then continue here.

To bring the disk array back to a state of Optimal, complete the following steps:

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. If necessary, select Create an Array Candidate pdisk and Format to 528 Byte Sectors.
3. Select Reconstruct a SAS Disk Array.
4. Select the failed pdisk to reconstruct.

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.
