dmtvol (dismount_volume) -- Dismount a logical volume.
usage: dmtvol {w | s | f}[unit] [log_vol_number]
[pathname] [-fu | -nw]
DESCRIPTION
dmtvol dismounts a logical volume that was previously mounted with the
mtvol (mount_volume) command. After the volume has been dismounted, it is
unavailable for further access.
ARGUMENTS
ddevice (required)
Specify the type of disk on which the volume resides: w
for a Winchester disk, s for a storage module, or f for a
floppy disk.
unit (optional)
Specify a unit number (0 or 1 only) for the device, if
necessary. For example, s1 denotes storage module unit 1.
Default if omitted: 0 (zero)
log_vol_number (optional)
Specify the number of the logical volume to be dismounted.
Default if omitted: 1
pathname (optional)
Specify the entry directory of the logical volume. If
you include this argument, dmtvol dismounts the volume and
uncatalogs its entry directory. If you omit it, dmtvol
dismounts the logical volume, but retains its name in the
naming tree.
OPTIONS
-fu Forcibly unlock any locked objects, then dismount the
volume. If you omit this option, the dismount fails if
the volume contains any locked objects.
-nw Prevents dmtvol from trying to write to the disk during
the dismount. Normally, writing to the disk saves current
information. However, if the disk was removed prior to
the dismount, you should use this option.
EXAMPLES
Dismount storage module unit zero, logical volume 2, and leave its name
in the naming tree.
$ dmtvol s 2
Dismount floppy unit zero, logical volume 1, and delete its name from the
naming tree.
$ dmtvol f /floppy
