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!
