ABSTRACT:
The present invention in at least some embodiments relates to improved methods and systems for governing access to SAN data storage devices (or simply “SAN devices”) employed in SAN systems. In some embodiments, the method involves storing a list at a SAN device. The list can be an exclusion list identifying devices that are not allowed to access the SAN device. During normal operation, the SAN device automatically contacts the SAN (or a component of the SAN, such as a SAN switch) to determine the identities of new devices that have entered into communication with the SAN. The SAN device then automatically updates the exclusion list to include those new devices such that, without further instructions, the SAN device is not accessible by those new devices. The method further can relate to the setup and failure recovery of SAN devices employed in SAN systems.
