v Yes: Work with the system operator to complete the appropriate problem handling procedures. See
the Getting started with server troubleshooting page in the Troubleshooting and service topic in the
iSeries Information Center.
This ends the procedure.
v No: Perform the steps that follow on the system's physical panel and not on the Partition Status
display in the Primary partition. Collect and record the failure data (see the iSeries Service
Functions ).
Note: If any of the data collection steps fail, go to step 3 (See page 29).
a. Select Manual mode (see Control Panel Functions in the iSeries Service Functions
b. Select Function 25 on the control panel and press Enter.
c. Select Function 26 on the control panel and press Enter.
d. Select Function 50 on the control panel and press Enter to stop the system. After a short time,
SRC D141900F displays and indicates the system is stopped.
e. Select Function 51 on the control panel and press Enter. The display shows 51**.
f. Select 5100 on the control panel and press Enter. Record the value displayed on the control
panel (first part of the address for the instruction to be executed next on processor 0).
g. Select 5101 on the control panel and press Enter. Record the value displayed on the control
panel (second part of the address for the instruction to be executed next on processor 0).
h. Select 5102 on the control panel and press Enter. Record the value displayed on the control
panel (first part of the address for the instruction being executed on processor 0).
i. Select 5103 on the control panel and press Enter. Record the value displayed on the control
panel (second part of the address for the instruction being executed on processor 0).
Notes:
1) If the system has multiple processors, the preceding steps can be repeated for each
processor by continuing the sequence with the selection of 5104 for the next processor.
2) When you have completed the data collection, exit the 51xx extended functions by rolling
back to the 51** display and pressing Enter.
Continue with the next step.
2. Go to the Primary partition's main menu.
a. Select Work with Partitions—>Display Partition Information—>Display Partition Processing
Configuration.
b. Select option 10 and continue selecting option 10 until you determine which processor or
processors failed. Record the failing processor numbers as part of the data collected for the APAR.
c. Record this information with the APAR data that you recorded earlier in this procedure.
3. Initiate a Main Store Dump (see Working with Storage Dumps in the iSeries Service Functions
by performing the following:
a. Go to the Primary partition's SST/DST display.
b. Select Work with Partitions—>Work with Partition Status—>More Options—>Force Main
Store Dump.
c. Wait for the dump to disk to complete (this may take several minutes).
Is 0000 0000 displayed on the partition status screen for more than 30 seconds?
v No: Continue with the next step.
v Yes: The Main Store Dump cannot complete successfully. The Load Source IOP is in a hang
condition. Perform a Load Source IOP dump (see Working with Storage Dumps in the iSeries
Service Functions
Go to step 5 (See page 30).
. Select Function 70 on the control panel and press Enter.
