The reconfiguration must involve an integral number of physical disks.
Objects to be moved must not contain open volumes.
Disks cannot be moved between CDS and non-CDS compatible disk groups.
Moved volumes are initially disabled following a disk group move, split or join. Use the vxrecover-m and vxvolstartall commands to recover and restart the volumes.
Data change objects (DCOs) and snap objects that have been dissociated by Persistent FastResync cannot be moved between disk groups.
Veritas Volume Replicator (VVR) objects cannot be moved between disk groups.
For a disk group move to succeed, the source disk group must contain at least one disk that can store copies of the configuration database after the move.
For a disk group split to succeed, both the source and target disk groups must contain at least one disk that can store copies of the configuration database after the split.
For a disk group move or join to succeed, the configuration database in the target disk group must be able to accommodate information about all the objects in the enlarged disk group.
Splitting or moving a volume into a different disk group changes the volume's record ID.
The operation can only be performed on the master node of a cluster if either the source disk group or the target disk group is shared.
In a cluster environment, disk groups involved in a move or join must both be private or must both be shared.
When used with objects that have been created using the Veritas Intelligent Storage Provisioning (ISP) feature, only complete storage pools may be split or moved from a disk group. Individual objects such as application volumes within storage pools may not be split or moved.
See the Veritas Storage Foundation Intelligent Storage Provisioning Administrator's Guide.
If a cache object or volume set that is to be split or moved uses ISP volumes, the storage pool that contains these volumes must also be specified.
