Abstract:
1. A method of identifying storage system enclosures, comprising: identifying a topology of enclosures within the storage system by performing the following: determining whether a first controller is connected to at least one enclosure in the storage system; in the event that the first controller is connected to at least one enclosure, defining the cable order of the enclosures based on the chain of enclosures as connected to the first controller; in the event that the first controller is not connected to at least one enclosure, defining the cable order of the enclosures based on the reverse of its chain of enclosures as connected to a second controller; generating unique enclosure identifiers (IDs) in ascending order based on the defined cable order; and assigning enclosures in the storage system a unique enclosure ID based on the identified topology of enclosures within the storage system and the defined cable order.
