Many of them told me that the Sun cards do not support fabric connections. 
While this is true of the ISP2100 card, the new ISP2200 card which I am 
using does support fabric connections as well as loops. Andrew McVey 
reminded me to use the switchshow command on the Brocade switches and it 
will tell you what type of connection is being made. The switches do show a 
fabric connection so my problem is not with the HBA cards as I had 
expected. My original problem of not seeing the LUNs from the server has 
not been fixed yet. Several of you also mentioned the sd.conf file which 
has also been configured per Hitachi specs. If anyone has any additional 
ideas I would be very grateful.

Thanks again.
