Veritas Volume Manager 5.1 SP1 Administrator"s Guide (5900-1506, April 2011)

For example, to set the policy for vol01 to read preferentially from the plex
vol01-02, use the following command:
# vxvol -g mydg rdpol prefer vol01 vol01-02
To set the read policy to select, use the following command:
# vxvol [-g diskgroup] rdpol select volume
See “Volume read policies” on page 487.
Removing a volume
If a volume is inactive or its contents have been archived, you may no longer need
it. In that case, you can remove the volume and free up the disk space for other
uses.
To remove a volume
1
Remove all references to the volume by application programs, including
shells, that are running on the system.
2
If the volume is mounted as a file system, unmount it with the following
command:
# umount /dev/vx/dsk/diskgroup/volume
3
If the volume is listed in the /etc/fstab file, edit this file and remove its
entry. For more information about the format of this file and how you can
modify it, see your operating system documentation.
4
Stop all activity by VxVM on the volume with the following command:
# vxvol [-g diskgroup] stop volume
5
Remove the volume using the vxassist command as follows:
# vxassist [-g diskgroup] remove volume volume
You can also use the vxedit command to remove the volume as follows:
# vxedit [-g diskgroup] [-r] [-f] rm volume
The -r option to vxedit indicates recursive removal. This command removes
all the plexes that are associated with the volume and all subdisks that are
associated with the plexes. The -f option to vxedit forces removal. If the
volume is still enabled, you must specify this option.
