[aic7xxx] "parity error" while installing in a SCSI drive with Adapctec 2940U
Last modified: 2007-04-18 12:53:19 EDT
Description of problem:
When I install RedHat 9 in a SCSI disk with a SCSI Adapter Adaptec 2940U,
I got this error in Alt+F4 console:
(SCSI0:A:6:0) parity error detected in Data-in phase. SEQADDR(0x1a2)
Is this a critical error message?
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install RH9 in a SCSI disk
Appears to be a message from the kernel, reassigning.
This problem ocurred when I was using 2 cp commands in background to copy data
from one disk to another. Something like this:
cp -a home usr /mnt/new &
cp -a var boot /mnt/new &
I was in rescue mode.
Later, I booted again in rescue mode and issue one cp command at a time and could
not see any error.
At this stage I don't have too many info about the error message nor how to
reproduce it. Maybe it was a problem with my SCSI adapter. I restored the
default settings in the SCSI BIOS before I tryied again.
Got more info.
I manage to upgrade a RH70 to RH9 and while working on the server I noted the
"kernel: (scsi:A:6:0): parity error detected in Status phase. SEQADDR(0x7f)
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
