Resizing a volume
Note: If specified, the -b option makes growing the volume a background task.
For example, to extend volcat by 100 sectors, use the following command:
# vxassist -g mydg growby volcat 100
Note: If you previously performed a relayout on the volume, additionally specify
the attribute
layout=nodiskalign to the growby command if you want the
subdisks to be grown using contiguous disk space.
Shrinking to a given length
To shrink a volume to a specific length, use the following command:
# vxassist [-g diskgroup] shrinkto volume length
For example, to shrink volcat to 1300 sectors, use the following command:
# vxassist -g mydg shrinkto volcat 1300
Caution: Do not shrink the volume below the current size of the file system or
database using the volume. The
vxassist shrinkto command can be safely used
on empty volumes.
Shrinking by a given length
To shrink a volume by a specific length, use the following command:
# vxassist [-g diskgroup] shrinkby volume length
For example, to shrink volcat by 300 sectors, use the following command:
# vxassist -g mydg shrinkby volcat 300
Caution: Do not shrink the volume below the current size of the file system or
database using the volume. The
vxassist shrinkby command can be safely used
on empty volumes.
Resizing volumes using vxvol
To change the length of a volume using the vxvol set command, use the
following command:
# vxvol [-g diskgroup] set len=length volume
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
