3. Perform the following:
a. Power off the system (see “Powering On and Powering Off the System and
Logical Partitions” on page 922).
b. Power on the system in Manual mode.
c. Wait for the system to complete the IPL to dedicated service tool (DST) (the
control panel SRCs go beyond C6xx 4103).
Is a display shown on the console?
Yes No
↓ The problem is not intermittent.
If you were sent here from Chapter 2. Unit Reference Codes, return
there and follow the procedure for a problem that is not intermittent.
If the problem continues, replace the service processor hardware
(SYMBOLIC FRU = “SVCPROC” on page 598).
This ends the procedure.
4. The problem is intermittent.
Save the IOP dump to tape (see “Copying the Service Processor Storage Dump
to Removable Media” in the iSeries Service Functions information).
5. Complete the IPL.
6. Go to the General Intermittent Problem Checklist in “Analyzing Intermittent
Problems” on page 14 to find available PTFs for this problem. Follow the steps
to find and apply a program temporary fix (PTF) for this problem (see the PTF
summary list to find PTFs with this SRC symptom).
Then return here and answer the following question.
Did you find and apply a PTF for this problem?
No Yes
↓ This ends the procedure.
7. Ask your next level of support for assistance and provide the following:
v The complete SRC you recorded in this procedure
v The service processor dump to tape you obtained in step 4 of this procedure
v All known system symptoms:
– How often the intermittent problem occurs
– System environment (IPL, certain applications)
– If necessary, other SRCs that you suspect relate to the problem
v Information needed to write an LICTR (see “APAR or LICTR” in the iSeries
Service Functions information)
This ends the procedure.
Licensed Internal Code (LIC) Problem Isolation Procedures
Overview
This section contains the procedures necessary to isolate Licensed Internal Code
reference code problems.
Read all safety procedures before servicing the system. Observe all safety
procedures when performing a procedure. Unless instructed otherwise, always
power off the system or expansion tower where the FRU is located, (see “Powering
Intermittent PIPs
