v If the I/O adapter is attached to an auxiliary cache I/O adapter, ensure that the SCSI cable on thelast 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 Type, model, and part number list.This ends the procedure.SDIOP-PIP31: For use by authorized service providers.Cache data associated with the attached devices cannot be found.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 theproblem. To determine if the system has logical partitions, go to Determine if the system has logicalpartitions before continuing with this procedure.2. Has the system been powered off for several days?v No: Go to step 4 (See page 4)v Yes: The cache battery pack may be depleted. Do NOT replace the I/O adapter or the cache batterypack. Reclaim the cache storage. See Reclaim IOP cache storage. Continue with the next step.Note: When an auxiliary cache I/O adapter connected to the storage I/O adapter logs a 9055 SRCin the Product Activity Log, the reclaim does not result in lost sectors. Otherwise, the reclaim doesresult in lost sectors, and the system operator may want to restore data from the most recent savedtape after you complete the repair.3. Does the IPL complete successfully?v No: Contact your next level of support. This ends the procedure.v Yes: This ends the procedure.4. Remove the I/O adapter. Install the new replacement storage I/O adapter with the following partsinstalled on it:Note: Label all parts (both old and new) before moving them.v The cache directory card from the original storage I/O adapter. See Type 2748, 2757, 2763, 2778,2780, 2782, 5703 - Cache directory card.v The removable cache card from the original storage I/O adapter (this applies to only some 2780 I/Oadapters). See Type 2748, 2757, 2763, 2778, 2780, 2782, 5703 - Cache directory card.v If the I/O adapter is attached to an auxiliary cache I/O adapter, ensure that the SCSI cable on thelast 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 Type, model, and part number list.5. Has a new 9010 or 9050 SRC occurred in the Service Action Log?v No: Go to step 8 (See page 8).v Yes: Continue with the next step.6. Was the new SRC 9050?v No: Continue with the next step.v Yes: Contact your next level of support. This ends the procedure.7. The new SRC was 9010. Reclaim the cache storage. See Reclaim IOP cache storage..Note: When an auxiliary cache I/O adapter that is connected to the storage I/O adapter logs a 9055SRC in the Product Activity Log, the reclaim does not result in lost sectors. Otherwise, the reclaimdoes result in lost sectors, and the system operator might want to restore data from the most recentsaved tape after you complete the repair.8. Remove the I/O adapter. Install the new replacement storage I/O adapter that has the following partsinstalled on it:v The cache directory card from the new storage I/O adapter.
