Hi Smack,

               External SCSI port is not used.

This sounds a lot like too many terminators.  

I also use the IBM DCAS-34330W drives, and found that they come with
termination jumpers installed on each disk. You may want to check
each disk to make sure that the jumper has been taken off each drive.  I 
don't know about the AHA-2940UW, but most SCSI cards also come with 
termination "on" as a default.
