204 Creating and administering disk groups
Reorganizing the contents of disk groups
For example, the following output from vxprint shows the contents of disk
groups rootdg and mydg:
# vxprint
Disk group: rootdg
TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0
dg rootdg rootdg - - - - - -
dm rootdg02 c1t97d0 - 17678493 - - - -

dm rootdg04 c1t114d0 - 17678493 - - - -
dm rootdg06 c1t98d0 - 17678493 - - - -
Disk group: mydg

pl vol1-02 vol1 ENABLED 3591 - ACTIVE - -
sd mydg05-01 vol1-02 ENABLED 3591 0 - - -
The following command moves the self-contained set of objects implied by
specifying disk mydg01 from disk group mydg to rootdg:
# vxdg -o expand move mydg rootdg mydg01
The moved volumes are initially disabled following the move. 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 move shows that not only mydg01 but also
volume vol1 and mydg05 have moved to rootdg, leaving only mydg07 and
mydg08 in disk group mydg:
# vxprint
Disk group: rootdg
