Booting in maintenance mode
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/DVD-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.
