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 AIX operating system be stopped so that 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.
Use the shutdown -m command to stop all activity on the AIX operating system and put the AIX operating
system into maintenance mode. The diag command is then used to invoke the diagnostic controller so you
can run the diagnostics. After the diagnostic controller is loaded, follow the normal diagnostic instructions.
Documentation for the AIX operating system is available from the IBM Eserver pSeries Information
Center at http://publib16.boulder.ibm.com/pseries/en_US/infocenter/base. Select AIX documentation. The
AIX Documentation CD contains the base set of publications for the operating system, including
system-management and end-user documentation.
