Patent ID: 8549361

Claim:
A method for construction, fault isolation, and recovery of cabling topology in a storage area network (SAN), comprising: obtaining subsystem information associated with each subsystem in the SAN using its respective interne protocol (IP) address by a cabling topology construction, fault isolation and recovery (CTCFIR) module residing in a management server connected to the SAN; obtaining an IP port and zoning information associated with connections of each subsystem in the SAN by the CTCFIR module; obtaining component information associated with each component in each subsystem in the SAN by sending commands by the CTCFIR module; compiling the obtained subsystem information, IP port and zoning information, and the component information; sending test packets from end-to-end in the SAN using the compiled information; tracking the sent test packets via each component in each subsystem in the SAN; and outputting the cabling topology of the SAN based on the outcome of the tracking, wherein sending the test packets from end-to-end in the SAN using the compiled information comprises sending the test packets via each IO path from end-to end in the SAN using the compiled information.
