Joining Dynamic Disk Groups
This procedure joins two dynamic disk groups by moving all VxVM objects from an
imported source dynamic disk group to an imported target dynamic disk group. The
source dynamic disk group is removed when the join is complete. This operation is
performed on VxVM VEA objects such as disks or top-level volumes, and includes all
component objects such as sub-volumes, plexes and subdisks.
▼ To perform a dynamic disk group join operation:
1. Select the dynamic disk group to be joined.
2. Select Actions > Join Dynamic Disk Group.
3. Use the source dynamic disk group name shown or replace it with one from the
pull-down menu.
4. Use the target dynamic disk group name shown, or replace it with one from the
pull-down menu.
5. Click OK.
Note:
◆ Before performing a join operation, stop all applications that are accessing the volumes,
and unmount all file systems that are configured in the volumes.
◆ The reconfiguration must involve an integral number of physical disks.
◆ Objects to be joined must not contain open volumes.
◆ Data change objects (DCOs) and snap objects that have been dissociated by Persistent
FastResync cannot be moved between dynamic disk groups.
◆ If your system supports VVR, then it should be noted that VVR objects cannot be moved
between dynamic disk groups.
◆ For a dynamic diskgroupjoin tosucceed, boththe sourceand target dynamic diskgroups
must contain at least one disk that can store copies of the configuration database after the
split.
