connected to, and whether the main controller is active or
inactive. An asterisk at the end of the first line in the display
response indicates that the controller is partitioned.
Displaying Information on a Volume
VOlume Info <volume name>
Displays the name and space allocation of the mounted
volume.
Mounting and Dismounting a Volume
VOlume Mount <device>
Makes the volume on the RSD accessible to the file system
and displays its name.
VOlume DISMount <volume name>
Use this command with caution. Takes the specified
volume off-line. If you dismount SYSUSER, a restart or
reload is necessary to mount the hard disk again. You
should dismount SYSUSER when upgrading the system
software or when powering down the system.
Backing Up and Restoring a Volume
VOlume Backup <volume name> ON <device>
Use this command with caution. Copies the contents of
the specified volume (for example, SYSUSER) to the
specified device (for example, RSD). If you specify
SYSUSER as the volume name, you must reload the system
to mount the hard disk again.
