2. Enter the diag command.
3. When the Diagnostic Operating Instructions are displayed, follow the instructions to check out the
resources that you want.
4. When testing is complete, press F3 to return to the Diagnostic Operating Instructions. Press F3 again

Maintenance mode
Maintenance mode runs the online diagnostics using the customer’s version of the NAS Gateway 500
System Software. This mode requires that all activity 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 Problem Determination on the
Diagnostic Mode Selection menu.
Use the shutdown -m command to stop all activity on the NAS Gateway 500 System Software and put
the NAS Gateway 500 System Software 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.
Running the online diagnostics in maintenance mode
To run the online diagnostics in maintenance mode, do the following:
1. Stop all programs running except the NAS Gateway 500 System Software (if help is needed, see the
system operator).
2. Log in to the NAS Gateway 500 System Software as root user. If clustering, you need to relocate this
node’s volumes over to the other cluster node (if help is needed, see “Stopping the system” on
page 310).
3. Type the
shutdown -m
command.
4. When a message indicates the system is in maintenance mode, enter the diag command.
Note: It might be necessary to set TERM type again.
5. When the Diagnostic Operating Instructions panel is displayed, follow the displayed instructions to
check out the resources that you want.
6. When testing is complete, press F3 to return to Diagnostic Operating Instructions. Press F3 again to
return to the NAS Gateway 500 System Software prompt.
