Abstract
A management station which manages the encryption devices in a SAN to set up encrypted LUNs. In setting up the encryption, the source and target ports are identified, along with the target LUN. LUN serial numbers used to identify unique LUNs. As paths to a given LUN are defined, the management station compares the path to existing paths and provides an indication if there is a mismatch in the encryption policies or keys being applied to the LUN over the various paths. This allows the administrator to readily identify when there is a problem with the paths to an encrypted LUN and then take steps to cure the problem. By determining the paths and then comparing them, the management station greatly simplifies setting up multipath I/O to an encrypted LUN or access by multiple hosts to an encrypted LUN.
