You can use the vol copy command to copy LUNs; however, this requires that applications accessing the LUNs are quiesced and offline prior to the copy operation.
Before You Begin
You must save contents of host file system buffers to disk before running vol copy commands on the storage system.
Considerations
The vol copy command enables you to copy data from one WAFL volume to another, either within the same storage system or to a different storage system. The result of the vol copy command is a restricted volume containing the same data that was on the source storage system at the time you initiate the copy operation.
Step
- To copy a volume containing a LUN to the same or different storage system, enter the following command: vol copy start -S source:source_volume dest:dest_volume
-S copies all Snapshot copies
in the source volume to the destination volume. If the source volume has Snapshot copy-backed LUNs, you must use the -S option to ensure that the Snapshot copies
are copied to the destination volume.
If the copying takes place between two storage systems, you can enter the vol copy start command on either the source or destination storage system. You cannot, however, enter the command on a third storage system that does not contain the source or destination volume.
Example
vol copy start -S /vol/vol0 filerB:/vol/vol1
