# vxdg join mydg rootdg

By default, VxVM automatically recovers and starts the volumes following a disk

group join. If you have turned off the automatic recovery feature, volumes are

disabled after a 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

Disk group: rootdg

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.
