Description
Refresh the contents of a volume group (the target volume group) from another volume group in
the same family. A backup snapshot set of the target volume group will be created before refresh 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. The table below outlines supported modes of operation and
resulting updates to source_id and source_time attributes of protection_data. |Target volume

clone(C2)|Current time| |Clone (C1) |snapshot set (C2S1) of clone (C2)|id of source snapshot set
(C2S1)|source_time of source snapshot set (C2S1)| Refresh operation is only supported if there are
no membership changes between the source and target volume groups of the refresh operation.
You can refresh a volume group even when the sizes of the volumes in the target volume group
have changed. This represents a case where the source volumes have been modified over time and
