I was way off base while discussing U2W and LVD. I had confussed the

Since I am no SCSI guru, can someone please explain, how to determine
which is active and which is passive?

the controller).
Also, make sure you have active (not passive) termination.

Lately, we have been experiencing some serious problems with our Linux servers
