DISCUTIL
Operation
88
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.
To invoke PDEV enter:
discutil>PDEV
The system responds with a display similar to:
CURRENT DEVICE CONFIGURATION:
LDEV : 1
VOLUME SET NAME : MPEXL_SYSTEM_VOLUME_SET
VOLUME NUMBER : 1
PATH : 2/4.0.0
LDEV : 21
VOLUME SET NAME : ACCOUNTING_VOL_SET
VOLUME NUMBER : 1
PATH : 6/4.0.0
LDEV : 22
VOLUME SET NAME : ACCOUNTING_VOL_SET
VOLUME NUMBER : 2
PATH : 6/4.0.1
REDO
Use REDO to modify and re-execute a command in the command history stack.
To invoke REDO enter:
discutil>REDO [ [CMD=]cmid]
For example:
discutil>REDO 5
