Introduction: This procedure performs an IPL to dedicated service tool (DST) to
determine if the same reference code occurs. If a new reference code occurs, more
analysis may be possible with the new reference code. If the same reference code
occurs, you are instructed to exchange the failing items.
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.
1.
Was the IPL performed from disk (Type A or Type B)?
No Yes
↓
Go to step 6 of this procedure.
2. Perform the following:
a. Ensure that the IPL media is the correct version and level that are needed
for the system model.
b. Ensure that the media is not physically damaged.
c. If the IPL media is cartridge type optical media (e.g. DVD), do not attempt
to clean the media.
If the IPL media is non-cartridge type media (e.g. CD-ROM), wipe the disc
in a straight line from the inner hub to the outer rim. Use a soft, lint-free
cloth or lens tissue. Always handle the disc by the edges to avoid finger
prints.
If the IPL media is tape, clean the recording head in the tape unit. Use the
correct IBM Cleaning Cartridge Kit.
3. Perform a Type D IPL in Manual mode.
Does a system reference code (SRC) appear on the control panel?
Yes No
↓
Go to step 9 of this procedure.
4. Is the SRC the same one that sent you to this procedure?
Yes No
↓
A different SRC occurred. Use the new SRC to correct the problem
(see “Starting Point for All Problems” on page 4).
This ends the procedure.
5. You cannot continue isolating the problem. Use the original SRC and exchange
the failing items, starting with the highest probable cause of failure (see the
failing item list for this reference code in “Chapter 2. Unit Reference Codes”
on page 59). If the failing item list contains FI codes, see “Failing Items” on
page 479 to help determine part numbers and location in the system.
This ends the procedure.
6. Perform an IPL to DST (see “Dedicated Service Tools (DST)” in the iSeries
Service Functions information).
Does an SRC appear on the control panel?
No Yes
↓
Go to step 11 of this procedure.
