The start snapImage rollback command starts a rollback operation for a set of snapshot images.

Supported Arrays

This command applies to any individual storage array, including the E2700, E5600, E2800, E5700, EF600 and EF300 arrays, as long as all SMcli packages are installed.

Roles

To execute this command on an E2800, E5700, EF600, or EF300 storage array, you must have the Storage Admin role.

Context

The content of the base volume changes immediately to match the point-in-time content of the selected snapshot image volume. The base volume immediately becomes available for read/write requests after the rollback operation has successfully completed. To stop a snapshot image rollback operation, use the stop rollback snapImage command.

The repository volume that is associated with the snapshot image continues to track any new changes between the base volume and the snapshot image volume that occur after the rollback operation is completed.

Note

You cannot use this command for snapshot images involved in online volume copy.

Syntax

start snapImage ["snapImageName"] rollback

Parameter

Parameter Description

snapImage

The name of the snapshot image. The name of a snapshot image is comprised of two parts:

  • The name of the snapshot group

  • An identifier for the snapshot image in the snapshot group

The identifier for the snapshot image can be one of these:

  • An integer value that is the sequence number of the snapshot in the snapshot group.

  • NEWEST — Use this option when you want to show the latest snapshot image created in the snapshot group.

  • OLDEST — Use this option when you want to show the earliest snapshot image created in the snapshot group.

Enclose the snapshot image name in double quotation marks (" ") inside square brackets ([ ]).

Notes

The name of a snapshot image has two parts separated by a colon (:):

  • The identifier of the snapshot group

  • The identifier of the snapshot image

For example, if you want to start a rollback operation for snapshot image 12345 in a snapshot group that has the name snapGroup1, you would use this command:

start snapImage ["snapGroup1:12345"] rollback;

To start a rollback operation for the most recent snapshot image in a snapshot group that has the name snapGroup1, you would use this command:

start snapImage ["snapGroup1:newest"]rollback;
