Running the online diagnostics in maintenance mode

Maintenance mode requires that all activity on the logical partition running the AIX^(R) operating system be stopped so that the online diagnostics have most of the resources available. All of the system resources, except the SCSI adapters, memory, processor, and the disk drive used for paging can be checked.

Perform the following steps to run the online diagnostics in maintenance mode:

1. Stop all programs running on the logical partition except the AIX operating system.
2. Log in to the AIX operating system as root user or use CE login.
3. Type the shutdown -m command to stop all activity on the AIX operating system and put it into maintenance mode.
4. When a message indicates that the system is in maintenance mode, enter the diag command to invoke the diagnostic controller so you can run the diagnostics.
   Note:
   It might be necessary to set TERM type again.
5. Enter any passwords, if requested.
6. When the Diagnostic Operating Instructions screen displays, follow the online instructions to check the desired resources.
   Note:
   If you do not receive the Diagnostic Operating Instructions display, try to run the standalone diagnostics. For details, see Running the eServer stand-alone diagnostics from CD-ROM.
7. When finished, press Ctrl+D to log off from root user or CE login.
8. Contact your next level of support or your hardware service provider with any information you received during the diagnostics, including service request numbers (SRNs).This ends the procedure.
