Cache data associated with the attached devices cannot be found.
You were sent to this procedure from URC 9010.
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.
Has the system been powered off for several days?
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.
Does the IPL complete successfully?
No: Contact your next level of support. This ends the procedure.
Yes: This ends the procedure.
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.
The removable cache card from the original storage I/O adapter
(this applies to only some 2780 I/O
adapters).
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 Part Information.
Has a new 9010 or 9050 SRC occurred in the Service Action Log?
Yes: Continue with the next step.
Was the new SRC 9050?
No: Continue with the next step.
Yes: Contact your next level of support. This ends the procedure.
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.
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.
The removable cache card from the new storage I/O adapter (this
applies to only some 2780 I/O adapters).
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 Part Information.
