Abstract
Two data storage systems, DS1 and DS2, may be initially configured with identifiers for target ports and target port groups. Subsequently, the two system may be combined into a cluster including a stretched volume configured from the volumes V1 and V2, respectively, on DS1 and DS2, where V1 and V2 are exposed to the host as the same logical volume, L1, over multiple paths from DS1 and DS2 to the host. V1 may have a normal attribute indicating target ports and port groups of DS1 have associated identifiers as specified in an initial configuration when reporting information regarding L1 to the host. V2 may have an extended attribute indicating that target ports and port groups of DS2 have associated extended identifiers determined using a first extended value and using identifiers from an initial configuration when reporting information regarding L1 to the host.
