Chapter 8. Verifying the Hardware OperationTo check the system for correct hardware operation, use the system verification procedure discussed inthis chapter.Considerations Before Running This ProcedureRead the following before using this procedure:v The AIX operating system must be installed on your system before you attempt to perform thisprocedure.v If this system unit is directly attached to another system unit or attached to a network, be surecommunications with the other systems are stopped.v This procedure requires use of all of the system resources. No other activity can be running on thesystem while you are performing this procedure.v This procedure requires a Hardware Management Console for pSeries (HMC), a display attached to agraphics adapter, or an ASCII terminal attached to the S1 or S2 port.v This procedure runs the AIX online diagnostics in service mode on a system booted in full systempartition mode.Does the system have AIX diagnostics preinstalled?YES If there is an HMC attached to the system, go to “Using the HMC to Load the OnlineDiagnostics in Service Mode”.If an HMC is not attached to the system, go to “Loading the Online Diagnostics on aSystem without an HMC Attached” on page 128.NO If there is an HMC attached to the system, go to “Using the HMC to Load the StandaloneDiagnostics from CD-ROM” on page 128.If an HMC is not attached to the system, go to “Loading the Standalone Diagnostics on aSystem without an HMC Attached” on page 129.Using the HMC to Load the Online Diagnostics in Service ModeTo run the online diagnostics in service mode from the boot hard disk, do the following from the HMC:1. Select Server and Partition.2. Select Partition Management.For more information about full system partitions, refer to the IBM Hardware Management Console forpSeries Installation and Operations Guide.3. From the HMC, select Server Management.4. In the Contents area, select the pSeries 650. Right-click on the mouse, and select Open TerminalWindow.5. From the Service Processor menu on the VTERM, select Option 2 System Power Control.6. Select option 6. Verify that the state changes to currently disabled. Disabling fast system bootautomatically enables slow boot.7. Select Option 98 to exit the system power control menu.8. Use the HMC to power on the pSeries 650 in full system partition mode by selecting the managedsystem in the Contents area.9. Highlight the desired system by right-clicking on or selecting the system in the Contents area. On themenu, choose Selected.10. Select Power On.127
