[KLUG Members] SCSI errors

[John Pesce]

I have an Adaptec 29160 Ultra160 SCSI controller.
I have three external RAID units daisy chained to it.
The one on the end has an external terminator. The other two has 
termination disabled.

The fartest out is ID:0, the closest is ID:2 and the middle is ID:1
IDs 0 and 1 are the same new models, ID 2 is my older different brand.

Whenever I write to ID:2 everything seems fine. Whenever I write to the 
other two I get errors almost continously.

Nov 20 10:32:43 myhost kernel: (scsi0:A:0:0): parity error detected in 
Data-out phase. SEQADDR(0x8b) SCSIRATE(0xc2)
Nov 20 10:32:43 myhost kernel: ^INo terminal CRC packet recevied


Anyone seen this before? Anyone have any ideas how to troubleshoot this?
