MAP 3232

Use this MAP to resolve the following problem: Cache data exists for one or more missing or failed disks (SRN nnnn-9051) for PCIe2 or PCIe3 controllers.

Step 3232-1

Identify the affected disks 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 Device Errors Detected field indicates the total number of disks which are affected. The Device Errors Logged field indicates the number of disks for that detailed information is provided. Under the Original Device heading, the Vendor/Product ID, S/N, and World Wide ID fields are provided for up to three disks. Additionally, the Original Controller Type, S/N, and World Wide ID fields for each of these disks indicate the adapter to which the disk was last attached when it was operational. See SAS resource locations to understand how to locate a disk by using the Resources field.
3. Go to Step 3232-2.

Step 3232-2

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

No

Go to Step 3232-3.

Yes

Go to Step 3232-6.

Step 3232-3

Is the data on the disks (and thus the cache data for the disks) needed for this or any other system?

No

Go to Step 3232-7.

Yes

Go to Step 3232-4.

Step 3232-4

Have the adapter card or disks been physically moved recently?

No

Contact your hardware service provider.

Yes

Go to Step 3232-5.

Step 3232-5

The adapter and disks must be reunited so that the cache data can be written to the disks.

Restore the adapter and disks back to their original configuration.

After the cache data is written to the disks and the system is powered off normally, the adapter or disks can be moved to another location.

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 3232-6

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 3232-7

Reclaim the Controller Cache Storage by performing 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 Diagnostics and Recovery Options > Reclaim Controller Cache Storage > IBM SAS RAID Controller.
3. Confirm that you will allow unknown data loss.
4. Confirm that you wish to proceed.

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.
