Haven’t played with FC drives yet
but it isn’t unusual in SAN environments to create redundant connections
to devices. Maybe they come with two ports to allow for that?
Not sure how you’d get your OS to
understand two paths to the same drives though. Since NBU can distinguish
busy drives on media servers maybe it can do so for two paths to same drive on
one server if in the same storage unit?

LTO4 come with 2 FC port ?
You may
have ordered them like that, I know we had to specify 4Gb for our T10Ks and
LTO3s.
Interesting
to see the SL is really a HP, didn't know they were rebranding them too.
I thought they only used Quantum
and StorageTek ?

Hi folks,
I have a
Sun SL48 with two HP LTO4 drives, why each LTO4 drive come with 2 FC ports ?
The
robotic can pass thru either Drive1 or Drive2 as multiLUN. In my case, the
robotic arm pass thru' using drive1 as following.
