Examining the hardware error log

The AIX® hardware error log is where the operating system keeps records about hardware errors, including disk arrays.

Note: Run diagnostics in Problem Determination (PD) mode to ensure that new errors are analyzed. These actions should be performed especially when using standalone diagnostic media.

Start the diagnostics program and select Task Selection on the Function Selection screen.
Select Display Hardware Error Report.
Select Display Hardware Errors for IBM SAS RAID Adapters.
Select the adapter resource, or select all adapters resources if the adapter resource is not known.
On the Error Summary screen, look for an entry with a SRN corresponding to the problem which sent you here and select it. If multiple entries exist for the SRN, some entries could be older versions or a problem has occurred on multiple entities (such as adapters, disk arrays, and devices). Older entries can be ignored, however, the MAP might need to be used multiple times if the same problem has occurred on multiple entities.
Return to the MAP that sent you here and continue with the steps in that MAP.
