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 override|verify] 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 a 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 376 for information
on how to move objects between disk groups in a cluster.
For example, the following output from vxprint shows the contents of
disk groups rootdg and dg1:
# vxprint
Disk group: rootdg
