PRIMIOA

Replace the storage I/O adapter to which the auxiliary cache I/O adapter is connected.

  1. Find the location of the auxiliary cache I/O adapter:
    1. Determine the address of the auxiliary cache I/O adapter. See System reference code (SRC) address formats, or see "System reference code (SRC) address formats" in the service guide for the system unit.
    2. Determine the location of the auxiliary cache I/O adapter. See Locating FRUs, or see "Locating FRUs" in the service guide for the system unit.
  2. Are you working on a 571F/575B combination storage and auxiliary cache IOA card set (uses two card slot locations)?
    • Yes: Replace the entire card set. This ends the procedure.
    • No: Continue with the next step.
  3. Trace the SCSI cable from the auxiliary cache I/O adapter to the storage I/O adapter. This is the storage I/O adapter that you should replace.
  4. Replace the storage I/O adapter that you just identified.

This ends the procedure.
