I have a really curious SCSI problem here and I think it is not
CAM/FreeBSD related but I just want to be sure...
This is an Adaptec 2940U2W controller.
The external LVD connector is unused. The internal LVD connector
has 2 IBM DNES-318350W LVD drives and a LVD terminator at the end
of the cable. The LVD terminator of the 2940U2W is set to on.
So the LVD segement is terminated properly.
The 50-pin (8bit) single ended connector has a SEAGATE ST31230N
drive and a PIONEER CD-ROM DR-766 1.00 cdrom drive attached to it.
On the end of this cable is an active 50-pin SE terminator.
The 68-pin (16bit) single ended connector has a IBM DDRS-34560W
connected to it. On the end of this cable is an active 68-pin SE
terminator. The SE terminator of the 2940U2W is set to LOW/Off
and HIGH/On.
So the SE segment is terminated properly.
The cable lengths are below 1 meter. I have changed them. I have
replaced the external terminators. I have set the 2940U2Ws
terminators to automatic. I have lowered the transfer speeds for
the SE devices. I have removed the CDROM.
I still get these SCSI Error messages.
I might think this is due to the old SEAGATE drive in there but I
am not sure. When removing the DDRS-34560W and correcting the
termination accordingly, the system ran fine for a long time. Now I
just wanted to replace the SEAGATE drive with the bigger DDRS-34560W
but as soon as I connect it to copy the stuff over, the problems
start.
Here is the dmesg with the relevant parts.
Maybe someone (Ken ?!? :-)) can give me a hint about this.
Thanks,
-Andre
