RE: FAS960 / DOT 7.0.1R1 / SAN LUN for Dell servers...? - toasters

13 Jul 2005


      Hi, Luke --
Thanks for taking the time to respond.
I've just re-verified that the cards have the correct & latest
BIOS firmware.  These range from old QLA2200 cards to new, Dell-
specific QLA2322 cards.
Since they all fail to see their NetApp LUNs, there must be
something going on that I just don't understand, but I don't know
what, since they see the DotHill RAID controller's masked LUNs.
Since the Dell servers can see the NetApp's HBAs, my guess is that
the NetApp's initiator groups are the most likely candidates.  Does
one use the WWPN listed in the switch's GUI, as I did for our HP-UX
servers?  Is there a way to serve a NetApp LUN without assigning it
to an initiator group (for debugging purposes)?
Thanks for your help!
