About this task

You were sent to this procedure from URC 9010.

Procedure

  1. If the system has logical partitions, perform this procedure from the logical partition that reported the problem.
    To determine if the system has logical partitions, go to Determining whether the system has logical partitions before continuing with this procedure.
  2. Has the system been powered off for several days?
    • No: Go to step 4.
    • Yes: The cache battery pack may be depleted. Do not replace the I/O adapter or the cache battery pack. Reclaim the cache storage. See Reclaiming IOP cache storage. Then continue with the next step.
      Note: When an auxiliary cache I/O adapter connected to the storage I/O adapter logs a 9055 SRC in the Product Activity Log, the Reclaim does not result in lost sectors. Otherwise, the Reclaim does result in lost sectors, and the system operator may want to restore data from the most recent saved tape after you complete the repair.
  3. Does the IPL complete successfully?
    • No: Contact your next level of support. This ends the procedure.
    • Yes: This ends the procedure.
  4. Remove the I/O adapter.
    Install the new replacement storage I/O adapter with the cache directory card from the original storage I/O adapter installed on it. On adapters with removable cache cards, the cache directory card will move with the removable cache card.
    Note: Label all parts (both old and new) before moving them.
    See Part locations and location codes.
    • If the I/O adapter is attached to an auxiliary cache I/O adapter, ensure that the SCSI cable on the last port of the new replacement storage I/O adapter is connected to the auxiliary cache I/O adapter. For a list of auxiliary cache I/O adapters, see System parts.
  5. Did the 9010 SRC that sent you to this procedure occur on a type-D IPL?
    • No: Continue with the next step.
    • Yes: Perform a type-D IPL and continue with the next step.
  6. Has a new 9010 or 9050 SRC occurred in the Service Action Log?
    • No: Go to step 9.
    • Yes: Continue with the next step.
  7. Was the new SRC 9050?
    • No: Continue with the next step.
    • Yes: Contact your next level of support. This ends the procedure.
  8. The new SRC was 9010. Reclaim the cache storage.
    See Reclaiming IOP cache storage.
    Note: When an auxiliary cache I/O adapter that is connected to the storage I/O adapter logs a 9055 SRC in the Product Activity Log, the reclaim does not result in lost sectors. Otherwise, the reclaim does result in lost sectors, and the system operator might want to restore data from the most recent saved tape after you complete the repair.
  9. Remove the I/O adapter.
    Install the new replacement storage I/O adapter that has the cache directory card from the new storage I/O adapter installed on it. On adapters with removable cache cards, the cache directory card will move with the removable cache card. See Part locations and location codes.
    • If the I/O adapter is attached to an auxiliary cache I/O adapter, ensure that the SCSI cable on the last port of the new replacement storage I/O adapter is connected to the auxiliary cache I/O adapter. For a list of auxiliary cache I/O adapters, see the System parts.
    This ends the procedure
