Chapter 7. Verifying the Hardware Operation
The system verification procedure checks the system for correct hardware operation.
Run the system verification procedure as described in the following steps.
If you are analyzing a hardware problem, see Chapter 8, “Hardware Problem
Determination” on page 145.
Step 1. Considerations Before Running This Procedure
Read the following before using this procedure:
v The AIX operating system must be installed on your system before you attempt to
perform this procedure.
v If this system unit is directly attached to another system unit or attached to a
network, be sure communications with the other systems are stopped.
v This procedure requires use of all of the system resources. No other activity can be
running on the system while you are performing this procedure.
v This procedure requires an Hardware Management Console for pSeries (HMC)
attached to the HMC port on the pSeries 690.
v This procedure runs the AIX online diagnostics in service mode on a full system
partition.
Does the system have AIX diagnostics preinstalled?
YES Go to “Step 2. Loading the Online Diagnostics in Service Mode”.
NO Go to “Step 2.5 Loading the Standalone Diagnostics from CD-ROM”
on page 142.
Step 2. Loading the Online Diagnostics in Service Mode
To run the online diagnostics in service mode from the boot hard disk, do the following:
1. Stop all programs including the AIX operating system (get help if needed).
2. Remove all tapes, diskettes, and CD-ROM discs.
3. Power off the managed system (refer to Full System Management Tasks in the
IBM
Hardware Management Console for pSeries Installation and Operations Guide
).
4. Use the HMC to power on the managed system in full system partition mode. Select
the Power on Diagnostic Stored Boot List option (see the
IBM Hardware
Management Console for pSeries Installation and Operations Guide
for more
information about full system partitions).
5. Enter any requested password.
Note: If you are unable to load the diagnostics to the point when the DIAGNOSTIC
OPERATING INSTRUCTIONS display, call your support center for assistance.
