My apologies to Brian and the rest of the list.
I was way off base while discussing U2W and LVD. I had confussed the

This crow doesn't taste very good.
I'm running 2-2-15.pre18 with the 2.2.14 raid patches with no problem. I
was running an 2940U2W and have just recently upgraded to an Ultra 160.
I've been running with the 2940 then the Ultra 160 in this mode for two
months with no lockups. RAID will stress the hell out of the SCSI bus and

No, haven't tried that. But I just might, even though we need the extra power
from a second CPU...

Since I am no SCSI guru, can someone please explain, how to determine
which is active and which is passive?
I went to the computer store, asked for a SCSI terminator and got it. It

You're problems occur only with RAID and the 2940U2W?
I was told it should be a SCSI problem, not a RAID problem. So, I quit
trying to debug RAID issues and went on to SCSI possibilities. Maybe the
guru was wrong?
My latest attempt _may_ bear some fruit. I tried lowering the speed from
80Mb to
Are you SURE it's not a cabling issue? I've had 2940U2w cards act strangely
both under Linux and NT when there were problems with cables or terminators.
I've gotten into the habit of using SCA drive cages and keeping the LVD
cable lengths to a minimum (just between the cage and the controller).
