This procedure resolves the problem when Cache data associated with attached disk units cannot be found.

1. Has the server been powered off for several days?

   No

   Go to step 2.

   Yes

   Go to step 5.

2. Using the appropriate service procedures, remove the adapter. Install the new replacement storage adapter with the following parts installed on it:
   Note: Label all parts (original and new) before moving them.
   • The cache directory card from the original storage adapter. Refer to Separating the 571F/575B card set and moving the cache directory card .
   • The removable cache card from the original storage adapter. This applies only to certain adapters that have a removable cache card.
3. Has a new SRC of xxxx9010 or xxxx9050 occurred?

   No

   Go to step 6.

   Yes

   Go to step 4

4. Was the new SRC xxxx9050?

   No

   The new SRC was xxxx9010. Reclaim adapter cache storage. See Reclaiming IOP cache storage .

   Attention: Data might be lost. When an auxiliary cache adapter connected to the RAID adapter logs a xxxx9055 SRC in the hardware error log, the reclaim process does not result in lost sectors. Otherwise, the reclaim process does result in lost sectors.

   Note: On the Reclaim Controller Cache Storage results screen, the number of lost sectors is displayed. If the number is 0, there is no data loss. If the number is not 0, data has been lost and the system operator might want to restore data after this procedure is completed.

   Go to step 6.

   Yes:

   Contact your hardware service provider. This ends the procedure.

5. If the server has been powered off for several days after an abnormal power-down, the cache battery pack might be depleted. Do not replace the adapter or the cache battery pack. Reclaim adapter cache storage. See Reclaiming IOP cache storage .
   Attention: Data might be lost. When an auxiliary cache adapter connected to the RAID adapter logs a xxxx9055 SRC in the hardware error log, the reclaim process does not result in lost sectors. Otherwise, the reclaim process does result in lost sectors.

   This ends the procedure.
6. Using the appropriate service procedures, remove the adapter. Install the new replacement storage adapter with the following parts installed on it:
   • The cache directory card from the new storage adapter. Refer to Separating the 571F/575B card set and moving the cache directory card .
   • The removable cache card from the new storage adapter. This only applies to certain adapters which have a removable cache card.
   This ends the procedure.
