The following command joins disk group mydg to rootdg:
# vxdg join mydg rootdg
The moved volumes are initially disabled following the join. Use the following
commands to recover and restart the volumes in the target disk group:
# vxrecover -g targetdg -m [volume ...]
# vxvol -g targetdg startall
The output from vxprint after the join shows that disk group mydg has been
removed:
# vxprint

Disabling a disk group
To disable a disk group, unmount and stop any volumes in the disk group, and
then use the following command to deport it:
# vxdg deport diskgroup
Deporting a disk group does not actually remove the disk group. It disables use
of the disk group by the system. Disks in a deported disk group can be reused,
reinitialized, added to other disk groups, or imported for use on other systems.
Use the vxdg import command to re-enable access to the disk group.
