restore Restore a volume group from a snapshot set. A primary or a clone volume group can only be restored from one of its immediate snapshot sets. A backup snapshot set of the target volume group will be created before restore is attempted. This behavior can be overridden by setting the create_backup_snap property to false. The profile for the backup snapshot set will be autogenerated unless a custom profile is specified. The auto-generated profile only initializes the name to an auto-generated, unique value. Other optional parameters are not specified. Restore operation is only supported if there are no membership changes between the target volume group and source snapshot set. You can restore a volume group even when the sizes of the volumes in the target volume group have changed. This represents a case where the target volumes have been modified over time, but you want to revert them back to their old state captured in the source snapshot set. When a volume group is restored, • source_time is set to the source_time of the snapshot set it is being restored from. A volume group that is acting as the destination in a replication session cannot be restored. Format volume_group {-id | -name } restore -from_snap_id [-create_backup_snap {yes | true | no | false}] [-backup_snap_profile -name [-description ]] [-async] Action qualifiers -id Unique identifier of the volume group. -name Unique name of the existing object (volume_group). -from_snap_id Unique identifier of the snapshot set to restore from.

restore

Restore a volume group from a snapshot set. A primary or a clone volume group can only be

restored from one of its immediate snapshot sets. A backup snapshot set of the target volume group

will be created before restore is attempted. This behavior can be overridden by setting the

create_backup_snap

property to false. The profile for the backup snapshot set will be auto-

generated unless a custom profile is specified. The auto-generated profile only initializes the name

to an auto-generated, unique value. Other optional parameters are not specified. Restore operation

is only supported if there are no membership changes between the target volume group and source

snapshot set. You can restore a volume group even when the sizes of the volumes in the target

volume group have changed. This represents a case where the target volumes have been modified

over time, but you want to revert them back to their old state captured in the source snapshot set.

When a volume group is restored,

•

source_time

is set to the

source_time

of the snapshot set it is being restored from.

A volume group that is acting as the destination in a replication session cannot be restored.

Format

volume_group {-id <value> | -name <value>} restore -from_snap_id <value> [-create_backup_snap

{yes | true | no | false}] [-backup_snap_profile -name <value> [-description <value>]] [-async]

Action qualifiers

-id

Unique identifier of the volume group.

-name

Unique name of the existing object (volume_group).

-from_snap_id

Unique identifier of the snapshot set to restore from. This is referred to as the source volume

group.

-create_backup_snap

This parameter specifies whether a backup snapshot set of the target volume group needs to

be created before attempting restore. This parameter defaults to true, if not specified.

-backup_snap_profile

Snapshot volume group request.

-name

Unique name of the snapshot set to be created.

-description

Optional description for the snapshot set. If description is not specified, the description for

the snapshot set will not be set.
