v Yes: The Product Activity Log and Service Action Log, in most cases, contains an SRC for the
optical storage unit when concurrent maintenance is performed which should be ignored. Perform
the following:
– Perform the Verification Procedures in the iSeries Service Functions
information to verify that the problem is corrected.
– Return the system to the customer and ensure that the customer verifies the system date and
time.
This ends the procedure.
2. Use the service action log to look for any new SRCs. See Use the Service action log.
Are there any new SRCs?
v No: Go to step 4 (See page 559).
v Yes: Continue with the next step.
3. Is the SRC the same as the original SRC?
v No: A new symptom may have occurred. Use the SRC information and go to System reference
codes to determine the cause of the problem.
This ends the procedure.

– Yes: Exchange the next failing item listed for this URC.
This ends the procedure.

4. Are you working with a tape device?
v No: Continue with the next step.
v Yes: Perform the Verification Procedures in the iSeries Service Functions

device description will be set to the "Failed" state because a resource change was detected.
Perform the following:
– Vary the tape device description off and back on before it can be used.
– Return the system to the customer and ensure that the customer verifies the system date and
time.
This ends the procedure.
5. Are you working with an IOP or an IOA?
v No: Perform the Verification Procedures in the iSeries Service Functions
to verify that the problem is corrected.
Resources which normally vary on automatically during IPL or which were previously varied on
manually, may need to be varied back on after Verification Procedures have been completed.
