To remove a self-contained set of VxVM objects from an imported source disk group to a new target disk group, use the following command:
# vxdg [-o expand] [-o override|verify] split
sourcedg
targetdg \
For a description of the -o
expand
, -o
override
, and -o
verify
options, see Moving objects between disk groups.
See Splitting disk groups for more information on splitting shared disk groups in clusters.
For example, the following output from vxprint
shows the contents of disk group rootdg
:
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0
dm rootdg01 c0t1d0s2 - 17678493 - - - -

pl vol1-02 vol1 ENABLED 3591 - ACTIVE - -
sd rootdg05-01 vol1-02 ENABLED 3591 0 - - -
The following command removes disks rootdg07
and rootdg08
from rootdg
to form a new disk group, mydg
:
# vxdg -o expand split rootdg mydg rootdg07 rootdg08
The moved volumes are initially disabled following the split. Use the following commands to recover and restart the volumes in the new target disk group:
# vxrecover -g
targetdg -m [
volume ...]
The output from vxprint
after the split shows the new disk group, mydg
:
