Oliver,
I 'll assume your cabling and terminations are OK.
Is this a one-time error, or at least an infrequent one? If so, it 's
probably a random data error on Channel A, SCSI ID=6, LUN=0 (a tape
drive?). I wouldn 't worry about it unless you start seeing multiple
errors. In that case you could have a cable problem or a device that needs
maintenance.
You could check the parity configurations of your Adaptec card and device
#6 to make sure they 're the same. If you disable parity on device #6
(usually via a jumper), parity will still be generated but any errors will
not be transmitted down the cable to the host adapter.
