Verifying the partition configurationPerform this procedure if there is a configuration problem with the system or a logical partition.Procedure1. Check the processor and memory allocations of the system or the partition. Processor or memoryresources that fail during system startup could cause the startup problem in the partition. Make surethat 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 loadsource 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 programYou can start or run the diagnostics program from the AIX operating system, from a CD, or from amanagement server.Starting AIX concurrent diagnosticsPerform this procedure to start AIX concurrent diagnostics from the AIX operating system.Procedure1. Log in to the AIX operating system as root user, or use the CE login. See “Creating a CE login” onpage 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 todisplay its Function Selection menu. See “Using the diagnostics program” on page 455 for moreinformation about running the diagnostics program.3. When testing is complete, press F3 until the Diagnostic Operating Instructions panel is displayed, andthen press F3 to exit the diagnostic program.Starting stand-alone diagnosticsPerform these procedures to start the stand-alone diagnostics from a CD or flash drive. These procedurescan be used if the compute node is running a Linux operating system or if an AIX operating systemcannot start the concurrent diagnostics program.About this taskYou can download the latest version of the stand-alone diagnostics from the Standalone Diagnostics CDpage.Procedure1. 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. Seethe documentation that comes with your operating system documentation for information aboutshutting down the operating system.Chapter 8. Troubleshooting 453
