Use this procedure to boot a system that is currently at run level 0 to run level S. This run level is used for system maintenance tasks, such as backing up a file system.
Boot the system to run level S.
ok boot -s |
Type the superuser password when the following message is displayed:
SINGLE USER MODE Root password for system maintenance (control-d to bypass): xxxxxx |
Verify that the system is at run level S.
# who -r |
Perform the maintenance task that required the run level change to S.
After you complete the system maintenance task, type Control-D to bring the system to the multiuser state.
