Note: Determine if the system has logical partitions. Go to “Determining if the
System Has Logical Partitions” on page 943, before continuing with this
procedure.
Note: If the system has logical partitions, perform this procedure from the logical
partition that reported the problem.
This procedure corrects the problem when the system cannot find the required
cache data for the attached disk units.
You were sent to this procedure from URC 9050.
1. Did you just exchange the storage input/output (I/O) adapter as a result of a
failure?
Yes No
↓
Go to “SDIOP-PIP23” on page 422.
This ends the procedure.
2. You have just exchanged a storage I/O adapter. The storage I/O adapter you
have just exchanged contains data which is required by the devices that were
attached to that adapter. If the storage I/O adapter that you just exchanged is
failing intermittently, reinstalling it and performing a manual IPL to DST may
allow the data to be successfully written to the devices.
Attention
: If the system is
NOT
powered down normally with the original card
in an
OPERATIONAL
state, customer data may be lost.
Perform the following:
a.
Replace the new cache directory card with the original cache directory card
from the failed storage I/O adapter (see “Type 2748, 2763, 2778 – Cache
Directory Card” on page 686).
b. A 9010 URC will occur. Ignore this and continue with the next steps.
3. Reclaim the cache storage (see “Reclaim IOP Cache Storage” on page 947).
Note: The system operator may want to restore data from the most recent
saved tape after you complete the repair.
4. Have any new SRCs occurred in the Service Action Log, or is the resource not
operational?
No Yes
↓
Go to “Starting Point for All Problems” on page 4 to correct the
problem.
This ends the procedure.
5. Before completing this service action, perform the following:
a. Replace the cache directory card from the failed storage I/O adapter with
the cache directory card that came with the replacement storage I/O
adapter that you exchanged in step 2a. (See “Type 2748, 2763, 2778 – Cache
Directory Card” on page 686.)
6.
Have any new SRCs occurred in the Service Action Log, or is the resource not
operational?
Yes No
↓
This ends the procedure.
7. Go to “Starting Point for All Problems” on page 4 to correct the problem.
This ends the procedure.
