rollback master-volume Description Rolls back (reverts) the data on a master volume to the data that exists in a specified snapshot. You can choose whether to include modified write data from the snapshot in the rollback. You must unmount/unpresent/unmap the master volume from hosts before using this command. The command will prompt you to ensure the master volume is unmounted/unpresented/unmapped before proceeding. CAUTION: All data that differs between the master volume and the snapshot is lost.
