SIP3132

Use this procedure to resolve the following problem: Cache data exists for one or more missing or failed disk units (SRC xxxx9051).

1. Identify the affected adapter and disk units by examining the product activity log. Perform the following steps:
   1. Access SST or DST.
      • If you can enter a command at the console, access system service tools (SST). See System service tools.
      • If you cannot enter a command at the console, perform an IPL to DST. See Performing an IPL to dedicated service tools.
      • If you cannot perform a type A or B IPL, perform a type D IPL from removable media.
   2. Access the Product Activity Log and record address information.

      If a type D IPL was not performed to get to SST or DST:

      The log information is formatted. Access the product activity log and display the SRC that sent you here. Press the F9 key for address information. This is the adapter address. Then, press F12 to cancel and return to the previous screen. Then press the F4 key to view the additional information to record the formatted log information. The Device Errors Detected field indicates the total number of disk units that are affected. The Device Errors Logged field indicates the number of disk units for which detailed information is provided. Under the Device heading, the unit address, type, serial number, and worldwide ID are provided for up to three disk units. Additionally, the adapter type, serial number, and worldwide ID for each of these disk units indicates the adapter to which the disk was last attached when it was operational.

      If a type D IPL was performed to get to DST:

      The log information is not formatted. Access the product activity log and display the SRC that sent you here. The direct select address (DSA) of the adapter is in the format BBBB-Cc-bb:

      BBBB

      Hexadecimal offsets 4C and 4D

      Cc

      Hexadecimal offset 51

      bb

      Hexadecimal offset 4F

      In order to interpret the hexadecimal information to get device addresses, see More information from hexadecimal reports . The Device Errors Detected field indicates the total number of disk units that are affected. The Device Errors Logged field indicates the number of disk units for which detailed information is provided. Under the Device heading, the unit address, type, serial number, and worldwide ID are provided for up to three disk units. Additionally, the adapter type, serial number, and worldwide ID for each of these disk units indicates the adapter to which the disk was last attached when it was operational.

   3. Determine the location of the adapter and the devices that are causing the problem. See System FRU locations and find the diagram of the system unit or the expansion unit. Then find the following items:
      • The card slot that is identified by the direct select address (DSA)
      • The disk unit locations that are identified by the unit addresses
      Have you determined the location of the adapter and the devices that are causing the problem?
      • No: Ask your next level of support for assistance. This ends the procedure.
      • Yes: Continue with the next step.
2. Are there other disk unit or adapter errors that have occurred at approximately the same time as this error?

   No:

   Go to step 3.

   Yes:

   Go to step 6.

3. Is the data on the disk units (and thus the cache data for the disk units) needed for this or any other system?

   No:

   Go to step 7.

   Yes:

   Go to step 4

4. Have the adapter card or disk units been physically moved recently?

   No:

   Contact your hardware service provider.

   Yes:

   Go to step 5.

5. Restore the adapter and disk units back to their original configuration. The adapter and disk units must be rejoined so that the cache data can be written to the disk units.

   After the cache data is written to the disk units and the system is powered off normally, the adapter or disk units can be moved to another location. This ends the procedure.

6. Take action on the other errors that have occurred at the same time as this error. This ends the procedure.
7. Reclaim adapter cache storage. See Reclaiming IOP cache storage.
   Attention: Data will be lost. This ends the procedure.
