Chapter 9. Hardware Problem Determination

This chapter provides information on using standalone or online diagnostics to help you solve hardware
problems.
You may obtain more extensive problem isolation by running online diagnostics in service mode. This
requires that the partition be rebooted (in a logical partitioned system) with no other users on that partition
or that the system be rebooted (in a full system partition) with no other users on the system. Alternatively,
if AIX online diagnostics are installed on the partition or system, you can run online diagnostics in
concurrent mode. If the system or partition does not have AIX diagnostics installed, or if you cannot boot
AIX or online diagnostics in service mode, run standalone diagnostics instead.

Problem Determination Using the Standalone or Online Diagnostics

Use this procedure to obtain a service request number (SRN) when you load the standalone or online
diagnostics. If you are unable to load the standalone or online diagnostics, go to "Problem Determination
When Unable to Load Diagnostics" on page 147. The service organization uses the SRN to determine
which field replaceable units (FRUs) are needed to restore the system to correct operation.
Step 1. Considerations before Running This Procedure
Note: See the IBM Hardware Management Console for pSeries Installation and Operations Guide to find
the key sequences you need for your Hardware Management Console for pSeries (HMC) virtual
terminal window to respond to the diagnostic programs.
v The diagnostics may be run within a virtual terminal window on the HMC connected to the system.
v This procedure requires that you select the type of diagnostics you want to run.
v Go to "Step 2."
Step 2
Are the online diagnostics installed on this system?
Note: Online diagnostics are not installed if the operating system is Linux.
NO
Go to "Step 15" on page 146.
YES
Go to "Step 3" on page 142.
