Creating and administering disk groups 203

Reorganizing the contents of disk groups

Moving objects between disk groups

To move a self-contained set of VxVM objects from an imported source disk group to an imported target disk group, use the following command:

#vxdg [-o expand] [-o overrideverify] move sourcedg targetdg \ object ...

The -o expand option ensures that the objects that are actually moved include all other disks containing subdisks that are associated with the specified objects or with objects that they contain.

The default behavior of vxdg when moving licensed disks in an EMC array is to perform an EMC disk compatibility check for each disk involved in the move. If the compatibility checks succeed, the move takes place. vxdg then checks again to ensure that the configuration has not changed since it performed the compatibility check. If the configuration has changed, vxdg attempts to perform the entire move again.

The -o override option enables the move to take place without any EMC checking.

The -o verify option returns the access names of the disks that would be moved but does not perform the move.

Note: The -o override and -o verify options require a valid EMC license.

See “Moving objects between disk groups” on page 424 for information on how to move objects between disk groups in a cluster.
