Step 1321-31
If no additional error information is available and the problem has not been corrected, shut down the
system.
If an HMC is not attached, you need a laptop computer (and cable, part number 62H4857) capable of
connecting to serial port 1 on the processor subsystem.
Note: The Linux login prompt cannot be seen on a laptop computer connected to serial port 1.
1. If there is no HMC, attach the laptop computer and cable to serial port 1 on the processor subsystem.
2. When OK displays in the operator panel, press a key on the virtual terminal on the laptop computer.
The service processor menus are available on the attached laptop computer or on the HMC.
3. Examine the service processor (SP) error log. Record all error codes and messages written to the SP
error log. Go to "Step 1321-32."
4. If the service processor menus are not available, perform the following steps:
a. Examine and correct all connections to the service processor.
b. Replace the service processor.
Note: The service processor might be contained on a separate card or book. Or in some systems,
the service processor is built into the service processor/PCI backplane, or into the system
backplane.
c. If you have not already replaced the system backplane in an earlier step, replace the system
backplane.
Note: Call service support before replacing the system backplane.
Step 1321-32
Boot the system to the system management services (SMS) menus. Record all error codes and messages
written to the SMS error log.
Step 1321-33
Were any error codes recorded in steps 1321-31 or 1321-32?
No Go to "Step 1321-41" on page 183.
Yes Go to the "Quick Entry MAP" on page 153 with each error code or symptom you have recorded.
Perform the indicated actions, one at a time, until the problem has been corrected. If all recorded
error codes have been processed and the problem has not been corrected, go to "Step 1321-41"
on page 183.
Step 1321-34
Reboot the system and and bring all partitions to the login prompt. If Linux is not usable in all partitions, go
to "Step 1321-38" on page 183.
Step 1321-35
Use the lscfg command to list all resources assigned to all partitions. Record the adapter and the partition
for each resource.
