Parity errors

Hi all,
on an old server I installed 2.0 release. The machine is an old HP server with two scsi drives and one pci card controller. I've configured a geom mirror during the installation, using the proposed partition layout.
Now I'm getting a lot of errors on the console like the following:

(da0:ach0:0:0:0):parity error detected in Message-in phase. SEQADDR(0x1a7)
SCSIRATE (0x95)

and after a two days of functioning the machine has become unresponsive. I guess it is an hard disk problem, but I need a little help understanding it.

Thanks

It does sound like either a hard disk failure, a controller failure or a cable failure.

I'd suspect the controller or cabling (and if that really is SCSI, termination).
