IOPIP41

Use this procedure to correct the problem when an auxiliary cache I/O adapter is not connected to a storage I/O adapter or when an auxiliary cache I/O adapter is connected to an incompatible or non-operational storage I/O adapter.

Perform the following:

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.
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 The System Reference Code (SRC) Format Description.
- The location identified is for the 575B 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 Physical Locations for the model you are working on. This ends the procedure.
- No: Change the configuration so that the same partition controls both cards in the card set. This ends the procedure.
Ensure that the SCSI cable of the auxiliary cache I/O adapter is connected to the last port of the storage I/O adapter. Do the following:
1. Use the location of the auxiliary cache I/O adapter displayed in the Service Action Log. If the Service Action Log does not have a location, determine the address of the auxiliary cache I/O adapter. See The System Reference Code (SRC) Format Description.
2. Determine the location of the auxiliary cache I/O adapter. See Physical Locations for the model you are working on.
3. Ensure that the SCSI cable of the auxiliary cache I/O adapter is properly connected to the last port of the storage 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 storage I/O adapter. If it is not, use concurrent maintenance to power on the slot.
Did you just replace the auxiliary cache I/O adapter because of a failure and did the new replacement auxiliary cache I/O adapter log a 9073 URC?
- Yes: The SCSI bus on the storage I/O adapter may be disabled as a result of the initial failure. Use Hardware Service Manager to re-IPL the storage I/O adapter that is connected to the new replacement auxiliary cache I/O adapter. This ends the procedure.
- No: Continue with the next step.
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.
Replace the SCSI cable that connects the auxiliary cache I/O adapter to the storage I/O adapter. If this does not fix the problem, replace the storage I/O adapter. This ends the procedure.
