Using volume copy

Command to use

You can use the volume copy command to copy LUNs; however, this requires that applications accessing the LUNs are quiesced and offline prior to the copy operation.

The vol copy start command enables you to copy data from one WAFL volume to another, either within the same filer or to a different filer. The result of the vol copy command is a restricted volume containing the same data as is on the source filer at the time you initiated the copy operation.

Copying a volume

To copy a volume containing a LUN to the same or different filer, complete the following step.

Caution
You must save contents of host file system buffers to disk before running vol copy commands on the filer.

Step	Action
1	Enter the following command: vol copy start -S source:source_volume dest:dest_volume Note If the copying takes place between two filers, you can enter the `vol copy start` command on either the source or destination filer. You cannot, however, enter the command on a third filer that does not contain the source or destination volume. Example vol copy start -S /vol/vol0 filerB:/vol/vol1

Step

Action

Enter the following command:

vol copy start -S source:source_volume dest:dest_volume

Note
If the copying takes place between two filers, you can enter the vol copy start command on either the source or destination filer. You cannot, however, enter the command on a third filer that does not contain the source or destination volume.

Example

vol copy start -S /vol/vol0 filerB:/vol/vol1
