volume recovery-queue show -vserver vs1

Below command will recover the volume from recovery queue

After using the recover command, the following steps must still be performed to access the data.

1. Rename the volume running the volume rename command.
2. Set up a junction, if required, running the volume mount command.
3. Create mappings for LUNs in the volume, if required, run the lun map command.
4. Associate a snapshot policy, an export policy with the volume, if required, with the volume modify command.
5. Add new quota policy rules for the volume, if required, with the quota policy rule command.
