196 Creating and administering disk groups
Reorganizing the contents of disk groups
Joining disk groups
To remove all VxVM objects from an imported source disk group to an imported target
disk group, use the following command:
# vxdg [-o override|verify] join sourcedg targetdg
Note: You cannot specify rootdg as the source disk group for a join operation.
For a description of the
-o override and -o verify options, see “Moving objects
between disk groups” on page 193.
See “Joining disk groups” on page 418 for information on joining disk groups in a cluster.
For example, the following output from
vxprint shows the contents of the disk group
rootdg and mydg:
# vxprint
Disk group: rootdg
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0
dg rootdg rootdg - - - - - -
dm rootdg01 c0t1d0 - 17678493 - - - -

dm rootdg07 c1t99d0 - 17678493 - - - -
dm rootdg08 c1t100d0 - 17678493 - - - -
Disk group: mydg
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0
dg mydg mydg - - - - - -
dm mydg05 c1t96d0 - 17678493 - - - -

pl vol1-02 vol1 ENABLED 3591 - ACTIVE - -
sd mydg05-01 vol1-02 ENABLED 3591 0 - - -
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
