Abstract
A method is provided to allow a user on a host system to update a specific snapshot in a data storage system where the user does not have other editing privileges. The method includes (1) receiving a request to update the snapshot from the user and (2) determining from an access control list if the user is permitted to update the snapshot. If the user is permitted to update the snapshot, the method includes (3) recording parameters for a VLUN (virtual logic unit) associated with the snapshot, (4) removing the VLUN from the data storage system, (5) replacing the snapshot with a new snapshot created from a parent volume of the snapshot, (6) recreating the VLUN for the new snapshot from the recorded parameters, and (7) exporting the VLUN to the host system.
