To change the length of a volume using the
set command, use the following command:
] set len=
For example, to change the length of the volume,
vol01, in the disk group,
mydg, to 100000 sectors, use the following command:
vxvol -g mydg set len=100000 vol01
len command cannot be used to increase the size of a volume unless the needed space is available in the plexes of the volume. When the size of a volume is reduced using the
len command, the freed space is not released into the disk group's free space pool.
If a volume is active and its length is being reduced, the operation must be forced using the
force option to
vxvol. This prevents accidental removal of space from applications using the volume.
The length of logs can also be changed using the following command:
] set loglen=
