FC uses a 64-bit identifier for a WWN. you end up with things like "50:00:0e:10:00:00:01:1c". ironically, FC switching doesn't actually 'use' the WWN but a 24-bit FC_ID. for things like mappings -- who knows -- perhaps WWN is good -- perhaps something like a serial # is also good -- perhaps both are good? mel-stglab-mds9509-1# show scsi-target lun vsan 1 - DF350F from HITACHI (Rev 0000) FCID is 0x7f0002 in VSAN 1, PWWN is 50:00:0e:10:00:00:01:1c ------------------------------------------------------------------------------ LUN Capacity Status Serial Number Device-Id (MB) ------------------------------------------------------------------------------ 0x0 16651 Online C:2 A:0 T:1 HITACHI D35067950000 0x1 16651 Online C:2 A:0 T:1 HITACHI D35067950001 - ST318452FC from HP (Rev HP03) FCID is 0x7f01da in VSAN 1, PWWN is 22:00:00:04:cf:8c:1f:95 ------------------------------------------------------------------------------ LUN Capacity Status Serial Number Device-Id (MB) ------------------------------------------------------------------------------ 0x0 17920 Online 3EV0JVQJ C:1 A:0 T:3 20:00:00:04:cf:8c:1f:95 [..] cheers, lincoln. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
