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

See "Moving objects between disk groups" on page 213.

  Note   You cannot specify rootdg as the source disk group for a join operation.

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 sda - 17678493 - - - -

dm rootdg02 sdb - 17678493 - - - -

dm rootdg03 sdc - 17678493 - - - -

dm rootdg04 sdd - 17678493 - - - -

dm rootdg07 sdg - 17678493 - - - -

dm rootdg08 sdh - 17678493 - - - -

Disk group: mydg

TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0

dg mydg mydg - - - - - -

dm mydg05 sde - 17678493 - - - -

dm mydg06 sdf - 17678493 - - - -

v vol1 fsgen ENABLED 2048 - ACTIVE - -

pl vol1-01 vol1 ENABLED 3591 - ACTIVE - -

sd mydg01-01 vol1-01 ENABLED 3591 0 - - -

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

The output from vxprint after the join shows that disk group mydg has been removed:

# vxprint

Disk group: rootdg

TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0

dg rootdg rootdg - - - - - -

dm mydg01 sda - 17678493 - - - -

dm rootdg02 sdb - 17678493 - - - -

dm rootdg04 sdd - 17678493 - - - -

dm mydg05 sde - 17678493 - - - -

dm rootdg06 sdf - 17678493 - - - -
