After connecting one of our machines to a Fibre Channel switch I've seen
various multipath devices appear as /dev/dm-0-5 and
/dev/mapper/mpath1-4. I need to find out which one of our Sun Storagetek
storage arrays these devices originate from, so I can work out which
volume I'm about to re-partition.
Thanks

Hi Tim,
I've never worked with a StorageTek system, but from our IBM SVC systems
i can match the WWN ID i get from multipath -ll. For example:
mpath1 (360050768018b801fe000000000000151) dm-11 IBM,2145
[size=32G][features=1 queue_if_no_path][hwhandler=0][rw]
\_ round-robin 0 [prio=100][active]
\_ 0:0:0:1 sdb 8:16 [active][ready]
\_ 1:0:0:1 sdl 8:176 [active][ready]
\_ round-robin 0 [prio=20][enabled]
\_ 0:0:1:1 sdg 8:96 [active][ready]
\_ 1:0:1:1 sdq 65:0 [active][ready]
I can take this WWN ID 360050768018b801fe000000000000151 and the
management interface allows me to filter for it. On my EVA systems i can
not filter for this but when i view the disk i see the WWN. You can also
match dm-11 with /dev/dm-11....
Hope this helps.
Bgrds,
Finnur
