Pb between an UltraTrak SX8000 and an Adaptec 29160

["didier" <didier@ece.gatech.edu>]

I have just connected a brand new UltraTrak SX8000
(from Promise with 8 x 200GB IDE drives) to an
adaptec 29160. The UltraTrak SX8000 is connected
via a brand new LVD cable (1meter).

While everything seems fine, I am getting a bunch of

(scsi0:A:0:0): parity error detected in Data-out phase. SEQADDR(0x56)
SCSIRATE(0xc2)
        No terminal CRC packet recevied

(scsi0:A:0:0): parity error detected in Data-out phase. SEQADDR(0x90)
SCSIRATE(0xc2)
        No terminal CRC packet recevied

in my /var/log/messages.

I was wondering if someone could give me some insight.

The UltraTrak SX8000 has its internal termination enabled.

Here is what I get during my boot:

Any idea ?

Thanks in advance for any suggestion
