IOPIP40

Use this procedure to isolate the problem when a storage I/O adapter is connected to an incompatible or non-operational auxiliary cache I/O adapter.

Perform the following:

  1. Are you working on a 571F/575B combination storage and auxiliary cache IOA card set (uses two card slot locations)?
    • Yes: Continue with step 2.
    • No: Continue with step 3.
  2. Find the location of the card.
    • Use the location displayed in the Service Action Log. If the Service Action Log does not have a location, determine the address of the I/O adapter. See System Reference Code (SRC) Format Description .
    • The location identified is for the 571F side of the card set.
    You must configure both the 571F and the 575B in the same partition. Are both the 571F side of the card set and the 575B side of the card set configured in the same partition?
    • Yes: Replace the entire card set. See System FRU locations for information on FRU locations on the system that you are servicing. This ends the procedure.
    • No: Change the configuration so that the same partition controls both cards in the card set. This ends the procedure.
  3. Ensure that the SCSI cable on the last port of the storage I/O adapter is connected to the auxiliary cache I/O adapter. Do the following:
    1. Use the location of the storage I/O adapter displayed in the Service Action Log. If the Service Action Log does not have a location, determine the address of the storage I/O adapter. See System Reference Code (SRC) Format Description .
    2. Determine the location of the storage I/O adapter. See System FRU locations for information on FRU locations on the system that you are servicing.
    3. Ensure that the SCSI cable on the last port of the storage I/O adapter is properly connected to an auxiliary cache I/O adapter.
    4. Ensure that both the auxiliary cache I/O adapter and the storage I/O adapter are in the same partition.
    5. Ensure that the slot power indicator is lit for the auxiliary cache I/O adapter. If it is not, use concurrent maintenance to power on the slot.
  4. Ensure that the auxiliary cache I/O adapter is supported for the storage I/O adapter to which it is connected. See the PCI adapter installation instructions for information about which adapters are compatible.
  5. Replace the SCSI cable on the last port of the storage I/O adapter that connects to the auxiliary cache I/O adapter. See System FRU locations for information on FRU locations on the system that you are servicing. If this does not fix the problem, replace the auxiliary cache I/O adapter. This ends the procedure.
