Logical Partition Hangs Or Loops (No Src) - IBM iSeries Series Hardware Problem Analysis And Isolation

b. Copy the main storage dump to media (see Working with Storage Dumps in the iSeries Service
Functions
Copy the main storage dump to removable media or disk. Copying to disk is faster than copying
to most types of tape devices. To successfully copy to disk, you must have enough space
available in auxiliary storage to hold the main storage dump.
c. Continue with the next step.
4. Perform the following:
a. Power off the system.
b. Power on the system in Manual mode.
Does the system IPL complete to DST?
v No: Continue with the next step.
v Yes: Go to "Use the service action log" on page 7.
This ends the procedure.
5. Does the system stop with a reference code displayed on the control panel?
v No: Continue with the next step.
v Yes: Go to System Reference Codes and use the SRC information to correct the problem.
This ends the procedure.
6. Did a Missing Disk Units display appear?
v No: Continue with the next step.
v Yes: Go to "Use the service action log" on page 7.
This ends the procedure.
7. Did the Main Store Dump Manager display appear?
v No: Contact your next level of support.
This ends the procedure.
v Yes: Record the SRC information available in the Main Store Dump Summary (see iSeries Service
Functions ). Then, go to System Reference Codes and use the SRC information to correct the
problem.
This ends the procedure.
Logical partition hangs or loops (no SRC): Use this procedure when a hanging or looping partition
does not display an SRC in the Primary partition's Work with Partition Status display. A logical partition
operation is hung when very low processor activity is indicated on the control panel, and the workstation
input is inhibited. It is in a loop when very high processor activity is indicated on the control panel, and the
workstation input is inhibited. A logical partition hang or loop is the result of either:
v A software failure.
v Software improperly handling a hardware failure.
The purpose of this procedure is to:
v Help you report the problem with enough error data to permit an APAR investigation to resolve the
software problem.
v Provide you with direction to identify any possible hardware failure.
It is assumed that the logical partition completed an IPL, and that at least one user successfully signed on
before the condition occurred.
Perform the following:
1. Is the logical partition operational from at least one workstation?
