Hello,
I am having problem with SCSI device. I am getting irregularly SCSI
error msg once or twice per week. Can anyone point out where I should start
troubleshooting?
It's Dell PowerEdge 1600SC and running Redhat 3.0 AS.
Thanks

ASC =47
ASCQ=0
Indicates a SCSI parity error when using the Quantum Atlas 10k disk drive. This is
a bus parity error - not a parity error of the data on the device, but rather
a parity error that occurs during data transfer between the device and the host.
These codes are enumerated in the SCSI Primary Commands ANSI Draft standard
avaiable for download from www.t10.org (spc3r17.pdf)
As for cause, look for a bad cable or loose connector first.
