Hi Doc, I disabled the parity in the SCSI board and the problem is solved. Is there any problem in disabling the parity in a SCSI board? I'm running the SCSI disc at 40MB/s
Thanks Oliver

Hi, I'm running RH9 and noted this error en /var/log/messages:
"kernel: (scsi:A:6:0): parity error detected in Status phase. SEQADDR(0x7f) SCSIRATE(0x88)"
The SEQADDR change with this values: 0x9e, 0xa5, 0x82
The Adaptec card is: AHA-2940 U/UW/D AIC-7881U
The mobo is an ASUS P4S-533-MX running a Pentium 4 1700Mhz
Anyone has seen this message? I want to know if this is a critical data
loss error.
I also have seen this error during install of RH8.0 in the same machine.
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.
