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 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:
Step 1. Select the dynamic disk group to be joined.
Step 2. Select Actions > Join Dynamic Disk Group.
Step 3. Use the source dynamic disk group name shown or replace it with one
from the pull-down menu.
Step 4. Use the target dynamic disk group name shown, or replace it with one
from the pull-down menu.
Step 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.
• For a dynamic disk group join to succeed, both the source and target
dynamic disk groups must contain at least one disk that can store
copies of the configuration database after the split.
