Verifying The Partition Configuration; Running The Diagnostics Program; Starting Aix Concurrent Diagnostics; Starting Stand-Alone Diagnostics - IBM Flex System p260 Installation And Service Manual

Verifying the partition configuration

Perform this procedure if there is a configuration problem with the system or a logical partition.
Procedure
1. Check the processor and memory allocations of the system or the partition. Processor or memory
resources that fail during system startup could cause the startup problem in the partition. Make sure
that the processor and memory have enough functioning resources in the system for all the partitions.
2. Check the bus and virtual adapter allocations for the partition. Make sure that the partition has load
source and console I/O resources.
3. Make sure that the boot mode partition properties are set to normal.
4. If the problem remains, contact your software service provider for further assistance.

Running the diagnostics program

You can start or run the diagnostics program from the AIX operating system, from a CD, or from a
management server.

Starting AIX concurrent diagnostics

Perform this procedure to start AIX concurrent diagnostics from the AIX operating system.
Procedure
1. Log in to the AIX operating system as root user, or use the CE login. See "Creating a CE login" on
page 25 for more information. If you need help, contact the system operator.
2. Type diag and press Enter at the operating system prompt to start the diagnostics program and to
display its Function Selection menu. See "Using the diagnostics program" on page 455 for more
information about running the diagnostics program.
3. When testing is complete, press F3 until the Diagnostic Operating Instructions panel is displayed, and
then press F3 to exit the diagnostic program.

Starting stand-alone diagnostics

Perform these procedures to start the stand-alone diagnostics from a CD or flash drive. These procedures
can be used if the compute node is running a Linux operating system or if an AIX operating system
cannot start the concurrent diagnostics program.
About this task
You can download the latest version of the stand-alone diagnostics from the Standalone Diagnostics CD
page.
Procedure
1. Verify with the system administrator and system users that the compute node might be shut down.
Stop all programs, and then shut down the operating system and shut down the compute node. See
the documentation that comes with your operating system documentation for information about
shutting down the operating system.
