Running the Online Diagnostics in Maintenance Mode
Maintenance mode runs the online diagnostics using the customer's version of the AIX operating system. This mode requires that all activity on the operating system be stopped so the online diagnostics have most of the resources available to check. All of the system resources except the SCSI adapters, memory, processor, and the disk drive used for paging can be checked.
Error log analysis is done in maintenance mode when you select the Problem
Determination option on the DIAGNOSTIC MODE SELECTION menu.
