To remove a volume
# umount /dev/vx/dsk/diskgroup/volume
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.
# vxvol [-g diskgroup] stop volume
# vxassist [-g diskgroup] remove volume volume
# 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.
