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:
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:
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 The System Reference Code (SRC) Format Description.
Determine the location of the storage I/O adapter. See Locating FRUs.
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.
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.
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 on the last port of the storage I/O adapter
that connects to the auxiliary cache I/O adapter. See Part Information for
cable part number information. If this does not fix the problem, replace the
auxiliary cache I/O adapter. This ends the procedure.
