IBM @Server pSeries 630 6E4, Service Manual

Page: 377 / 651

Use the shutdown -m command to stop all activity on the AIX operating system and put the AIX operating
system into maintenance mode. The diag command is then used to invoke the diagnostic controller so you
can run the diagnostics. After the diagnostic controller is loaded, follow the normal diagnostic instructions.
Documentation for the AIX operating system is available from the IBM
Eserver
pSeries Information
Center at http://publib16.boulder.ibm.com/pseries/en_US/infocenter/base. Select AIX documentation . The
AIX Documentation CD contains the base set of publications for the operating system, including
system-management and end-user documentation.
Running the Online Diagnostics in Maintenance Mode
To run the online diagnostics in maintenance mode, do the following:
1. Stop all programs running on the partition except the AIX operating system (if help is needed, see the
system operator).
2. Log in to the AIX operating system as root user or use CE Login.
3. Type the shutdown -m command.
4. When a message indicates the system is in maintenance mode, enter the diag command.
Note: It might be necessary to set TERM type again.
5. When DIAGNOSTIC OPERATING INSTRUCTIONS screen displays, follow the displayed instructions
to check out the desired resources.
6. When testing is complete, press the F3 key to return to DIAGNOSTIC OPERATING INSTRUCTIONS.
Press the F3 key again to return to the AIX operating system prompt.
7. Press Ctrl-D to log off from root user or CE Login.
Standalone Diagnostics Operations
Use standalone diagnostics to test the system when the online diagnostics are not installed and as a
method of testing the disk drives that cannot be tested by the online diagnostics.
Note: No error log analysis is done by the standalone diagnostics. The CD-ROM drive and the controller
that controls it cannot be tested by the standalone diagnostics. Standalone diagnostics:
v Are resident on CD-ROM or a Network Installation Management (NIM) server
v
Provide a method to test the system when the online diagnostics are not installed or cannot be
loaded from the disk drive
v Allow testing of the disk drives and other resources that cannot be tested by the online
diagnostics
v
Do not have access to the AIX configuration data
v Do not have access to the AIX error log
v
Do not allow for running of error log analysis
Considerations for Running Standalone Diagnostics on a Partitioned
System
To run standalone diagnostics on a full system partition, you must reboot the entire system. However, for a
partition in a partitioned system, you can boot standalone diagnostics either in a given partition or on the
entire system (which is the same procedure as a full system partition). When running in a multiple
partitioned system, the device from which you are booting standalone diagnostics must be made available
to the partition dedicated to running standalone diagnostics. This might require moving the device from the
partition that currently contains the boot device (for example, the CD-ROM or network adapter connected
to the NIM server that has a standalone diagnostic image) to the partition used to run standalone
diagnostics. Reboot both partitions if you move a device. Devices on a partitioned system are moved on
an I/O-slot basis.
