DISCUTIL
Operation
HELP
Use this command to get online help text for DISCUTIL commands. If you specify a
command name HELP displays text for that command. If you don't specify a command, you
will see a list of all available commands and their syntax.
To invoke HELP enter:
discutil>HELP [ [CMD=] cmdname ]
For example, to see a list of all commands and their syntax, enter:
discutil>HELP
Or, to see information about the MOUNT command, enter:
:HELP MOUNT
LISTREDO
Use this command to display the command line history stack/queue, ordered from the least
to the most recent command with absolute command reference numbers preceding each
command. Use LISTREDO in conjunction with the DO command to reissue commands you
previously entered.
To invoke LISTREDO enter:
discutil>LISTREDO
MOUNT
The MOUNT command is used to mount an unmounted volume. If the ldev represents a disk
and if the device is responding, DISCUTIL will attempt to mount the volume. Only MASTER
or MEMBER volumes can be mounted. Once mounted, a volume becomes available to
DISCUTIL and is added to its mounted volume table. The
ldev must be configured prior to
mounting a volume on it.
To invoke MOUNT enter:
discutil>MOUNT [LDEV=]
ldev
For example:
discutil>MOUNT 4
PDEV
The PDEV command displays the volume set name, volume number, and physical device
path for all the disks known to DISCUTIL. All disks that are configured successfully, either
at invocation or by the CONFIGURE command, are known to DISCUTIL. DISCUTIL reads the
mounted volume table and uses the table information to configure the disks listed in the
table.
The volume number is the volume's number in a volume set. For example, in a volume set
of three volumes, each volume is given a number from one to three. This allows you to
determine if you have all volumes of a volume set configured.
