DISCUTIL
Operation
DISMOUNT
Use the DISMOUNT command to logically dismount a volume. This command removes the
volume entry corresponding to the specified
ldev from DISCUTIL's mounted volume table,
thus making it inaccessible to DISCUTIL. After a volume has been logically dismounted,
the media or disk pack on the corresponding
ldev can be spun down, new media mounted
and spun up, then logically mounted with the MOUNT command. DISCUTIL will then
recognize the new media.
To invoke the DISMOUNT command enter:
discutil>DISMOUNT [LDEV=] ldev
For example:
discutil>DISMOUNT 4
DO
Use the DO command to re-execute a command from the command history stack/queue.
To invoke DO enter:
discutil> DO [ [CMD=]
cmdid ]
For example, to re-execute the fifth command, enter:
discutil>DO 5
DSTAT
Use this command to display information about each mounted volume (i.e., any volume
that is currently listed in the mounted volume table). To invoke DSTAT enter:
discutil>DSTAT
DSTAT displays the
ldev on which the volume is mounted, the type ID of the device, the
type (STATUS) of the volume, the volume name, and the physical path as shown in the
example below:
LDEV-TYPE STATUS VOLUME ( VOLUME SET-GEN ) PATH
