Abstract:
In a storage system having an enclosure containing redundant devices that serve to identify said enclosure, a method for generating a unique identity for said enclosure comprising the steps of:determining, in a first device of said redundant devices, a neighbor local identity of said enclosure presently stored as a local identity in a second device of said redundant devices; comparing said neighbor local identity to a saved neighbor local identity stored in said first device; updating a local identity in said first device in response to the comparison determining that said neighbor local identity is different from said saved neighbor local identity; detecting, in said first device, a status of said second device; selecting, in said first device, said local identity in said first device as said unique identity for said enclosure in response to a detection of a first status of said second device; and selecting, in said first device, said neighbor local identity in said second device as said unique identity for said enclosure in response to detection of a second status of said second device.
