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.
Destroying a disk group
The vxdg command provides a destroy option that removes a disk group from the
system and frees the disks in that disk group for reinitialization:
# vxdg destroy diskgroup
Caution: This command destroys all data on the disks.
When a disk group is destroyed, the disks that are released can be re-used in other disk
groups.
Recovering a destroyed disk group
If a disk group has been accidentally destroyed, you can recover it, provided that the disks
that were in the disk group have not been modified or reused elsewhere.
