Chandra Seetharaman a53becc9a9 [SCSI] dh_rdac: Use WWID from C8 page instead of Subsystem id from C4 page to identify storage ... rdac hardware handler uses "Subsystem Identifier" from C4 inquiry page to uniquely identify a storage. The problem with that is that if any any of the bytes are non-ascii, subsys_id will all be spaces (hex 0x20). This creates lot of problems especially when there are multiple rdac storages are connected to the server. Use "Storage Array Unique Identifier" from C8 inquiry page, which is the world wide unique identifier for the storage array, to uniquely identify the storage.
