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. Perform an IPL to dedicated service tool (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 6 of this procedure.
2. Does the Disk Configuration Error Report display or the Disk Configuration
Warning Report display appear on the console?
Yes No
↓
Go to step 4 of this procedure.
3. Does one of the following messages appear in the list?
v
Missing disk units in the configuration
v
Missing mirror protection disk units in the configuration
v
Device parity protected units in exposed mode.
No Yes
↓
Select option 5, then press F11, then press the Enter key to display the
details.
If all of the reference codes are 0000, go to “LIC-PIP 11” on page 350
and use cause code 0002. If any of the reference codes are not 0000, go
to step 6 of this procedure and use the reference code that is not 0000.
Note: Use the characters in the Type column to find the correct
reference code table.
4. Does the Display Failing System Bus display appear on the console?
No Yes
↓
Use the reference code that is displayed under Reference Code to correct
the problem.
This ends the procedure.
5. Look at all the Product Activity Logs by using the Product activity log option
under DST (see “Dedicated Service Tools (DST)” in the iSeries Service Functions
information). If there is more than one SRC logged, use an SRC that is logged
against the IOP or IOA.
Is an SRC logged as a result of this IPL?
Yes No
↓
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.
