If you need to perform maintenance on a standalone machine that is not part of the NIM environment, the system must be booted from a bootable tape or CD-ROM. This may require connecting an external device. If the machine is part of a NIM environment, you can enter maintenance mode directly by enabling the maint_boot operation for a NIM standalone machine.
To issue the maint_boot operation from the client, enter:
nimclient -o maint_boot -a spot=SPOTNAME
To issue the maint_boot operation from the master, enter:
nim -o maint_boot -a spot=SPOTNAME CLIENT
To verify that the maintenance boot operation worked:
nimclient -l -l ClientMachineObjectName
lsnim -l ClientMachineObjectName
If the operation was successful, the client's Cstate output will look similar to the following:
Cstate = maintenance boot has been enabled
For the machine to boot into maintenance mode, follow the procedure for issuing the BOOTP request from the client. See "Booting a Machine Over the Network" for more information about initiating a BOOTP request.
After successfully booting and defining the console, the System Maintenance menu is displayed. The maintenance menu options and their descriptions are described below. Detailed information about maintenance mode can be found in the AIX Version 4.3 Installation Guide.
