2. On the Start Service Tools Sign On display, type in a User ID with QSRV authority and Password.
3. Select Start a Service Tool —> Hardware Service Manager —> Work with service action log.
4. On the Select Timeframe display, change the From: Date and Time to a date and time prior to when
the customer reported having the problem.
5. Search for an entry that matches one or more conditions of the problem:
v SRC
v Resource
v Time
v FRU list
6. Perform the following:
v Choose Display the failing item information to display the SAL entry.
v Use the Additional Details function to switch between part descriptions and part locations
information.
All new entries in the Service Action Log represent problems that require a service action. It may be
necessary to handle any problem in the log even if it does not match the original problem symptom.
The information displayed in the date and time fields are the date and time for the first occurrence of
the specific system reference code (SRC) for the resource displayed during the time range selected.
7. Did you find an entry in the Service Action Log?
v Yes: Continue with the next step.
v No: Is the OS/400
– Yes: Go to "Use the problem log" on page 9.
This ends the procedure.
– No: Go to "Handle problems for non-critical resources" on page 11.
This ends the procedure.
8. Was the entry isolated (does the letter "Y" appear in the Isolated column)?
v No: Go to the System reference code list. Use the SRC that is indicated in the log to find the
correct SRC table and unit reference code. Perform all actions in the Description/Action column
before exchanging failing items.
Note: When exchanging failing items, the part numbers and locations found in the Service Action
Log entry should be used.
This ends the procedure.
v Yes: Display the failing item information for the Service Action Log entry. Items at the top of the
failing item list are more likely to fix the problem than items at the bottom of the list.
Notes:
– Some failing items are required to be exchanged in groups until the problem is solved.
– Other failing items are flagged as mandatory exchange and must be exchanged before the
service action is complete, even if the problem appears to have been repaired.
– Use the "Part Action Code" field in the SAL display to determine if failing items are to be
replaced in groups or as mandatory exchanges.
– Unless the "Part Action Code" of a FRUs indicates group or mandatory exchange, exchange
the failing items one at a time until the problem is repaired. Use the help function to determine
the meaning of Part Action Codes.
9. Perform the following to help resolve the problem:
a. For failing items, refer to the "Failing items" on page 249 page.
b. For symbolic FRUs, see the Symbolic FRUs page.
