IOPIP31

You were sent to this procedure from URC 9010.

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 if 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. Are you working with a 571F/575B card set?
   • No: Go to step 6.
   • Yes: Continue with the next step.
5. Remove the 571F/575B card set. Create a new card set with the following:
   Note:
   Label all parts (both original and new) before moving them.

   • The new replacement 571F storage IOA
   • The cache directory card from the original 571F storage IOA
   • The original 575B auxiliary cache adapter

   See Separating the 571F/575B card set and moving the cache directory card.

   • Ensure that the SCSI cable and the battery power cable on the top edge of the storage side of the card are connected to the top edge of the auxiliary cache side of the card.
   • Reinstall this card set into the system and go to step 7.
6. Remove the I/O adapter. Install the new replacement storage I/O adapter with the following parts installed on it:
   Note:
   Label all parts (both old and new) before moving them.
   • The cache directory card from the original storage I/O adapter. On adapters with removable cache cards, the cache directory card will move with the removable cache card.
   • The removable cache card from the original storage I/O adapter (this applies to only the 571E and some 2780 I/O adapters).
   See Locating FRUs.
   • 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.
7. 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.
8. Has a new 9010 or 9050 SRC occurred in the Service Action Log?
   • No: Go to step 11.
   • Yes: Continue with the next step.
9. Was the new SRC 9050?
   • No: Continue with the next step.
   • Yes: Contact your next level of support. This ends the procedure.
10. 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.
11. Are you working with a 571F/575B card set?
    • No: Go to step 13.
    • Yes: Continue with the next step.
12. Remove the 571F/575B card set. Create a new card set with the following:
    • The new 571F storage IOA
    • The cache directory card from the new 571F storage IOA
    • The new 575B auxiliary cache adapter
    See Separating the 571F/575B card set and moving the cache directory card.
    • Ensure that the SCSI cable and the battery power cable on the top edge of the storage side of the card are connected to the top edge of the auxiliary cache side of the card.
    • Reinstall this card set into the system.
    This ends the procedure.
13. Remove the I/O adapter. Install the new replacement storage I/O adapter that has the following parts installed on it:
    • The cache directory card from the new storage I/O adapter. On adapters with removable cache cards, the cache directory card will move with the removable cache card.
    • The removable cache card from the new storage I/O adapter (this applies to only the 571E and some 2780 I/O adapters).
    See Locating FRUs.
    • 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.
    This ends the procedure
