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 the master volume from the host operating system before using this command. The

command will prompt you to ensure the master volume is unmounted before proceeding.

CAUTION: All data that differs between the master volume and the snapshot is lost. Create a

snapshot of the master volume as it currently exists before performing a rollback.

Syntax

rollback master-volume volume snapshot volume [modifiedsnapshot yes|no]

[prompt yes|no]

Parameters volume

Name or serial number of the master volume to roll back. For syntax, type Command syntax.

snapshot volume

Command syntax.

modifiedsnapshot yes|no

prompt yes|no

Optional. Specifies an automatic response to the unmount prompt that either enables the rollback to

proceed or prevents the rollback from proceeding.

Example Roll back master volume MV1 to snapshot SS1:

# rollback master-volume MV1 snapshot SS1

Leaving the master volume mounted when starting a rollback operation will result

in data corruption. The master volume must be unmounted prior to beginning the

rollback operation. The master volume can be remounted once the rollback has

started. Not unmounting the volume prior to beginning the rollback operation

will result in data corruption.

Is the master volume unmounted from all operating systems? yes

Success: Command completed successfully. - Rollback was started.
