Abstract
A method and controller for implementing device physical location identification in a Serial Attached SCSI (SAS) fabric using resource path groups, and a design structure on which the subject controller circuit resides are provided. The device physical location identification includes a Resource Path Group (RPG). Each RPG provides a unique persistent physical locator of a storage device in the system. Each RPG including at least two Resource Paths (RPs) and each RP has a fixed size identifying a type and a series of egress ports. A persistent RPG is stored within the device metadata on the storage device.
