Before you move a volume nondisruptively, you must be aware of the types of volumes you can move and the operations that might conflict with the volume move. The volume move does not start if the volume has unsupported settings or if there are conflicting operations.
- Your Data ONTAP system must be running Data ONTAP
8.0.1 7-Mode or later.
- You can move only one 7-Mode FlexVol volume at a time.
- Moving a root volume requires clustered Data ONTAP 8.2 or later.
- The volume move cannot be initiated from or to a root aggregate.
- The volume must be online.
- The source volume must be consistent.
- You cannot move the following types of volumes:
- The source volume should not be exported to NFS or CIFS clients when the volume move operation is in progress.
There is a small window of time when you can export the source volume over NFS or CIFS before the volume move enters the cutover phase. However, if you do so, the cutover phase might not be successfully completed. If the cutover phase is not completed, there is no disruption to iSCSI clients because the volume move rolls back to continue with the data copy phase.
- The volume
guarantee option must not be set to
- Deduplication operations must not be running on the source volume.
If deduplication is active, the volume move is paused and the cutover phase is not initiated.
For more information about deduplication operations, see the
Data ONTAP Storage Management Guide for 7-Mode.
- The following operations must not be running, because they conflict with volume moves:
- SnapRestore of the source volume or the containing aggregate
- WAFLIron operation on the source or the destination aggregate
- Active LUN clone split operations on the source volume
- Revert operation on the storage system
Note: FlexClone volumes in the source volume are not moved along with the source volume. Fingerprint databases and change logs in the source volume are moved along with the source volume.
