I recently installed a SCSI tape drive and Adaptec AHA-2940U2W SCSI controller into my server to run backups.
Since then, the driver issues these warnings on a semi-regular basis while the drive is busy:
Aug 9 17:00:26 anu kernel: scsi0: Data Parity Error Detected during address or write data phase Aug 9 17:00:26 anu kernel: scsi0: PCI error Interrupt at seqaddr = 0x8
[...]
Aug 9 17:03:34 anu kernel: scsi0: Data Parity Error Detected during address or write data phase
[...]
Aug 9 17:04:36 anu kernel: scsi0: PCI parity error checking has been disabled. Aug 9 17:04:36 anu kernel: scsi0: Some device on this bus is generating bad parity. Aug 9 17:04:36 anu kernel: scsi0: This is an error *observed by*, not *generated by*, this controller. Aug 9 17:04:36 anu kernel: scsi0: Too many PCI parity errors observed as a target. Aug 9 17:04:36 anu kernel: scsi0: WARNING WARNING WARNING WARNING
Now, the log message claims that the SCSI controller is not responsible for these parity errors, so my questions are:
* should I panic about this? * should I have seen this before the SCSI controller was installed? * can I do anything about it, or identifying the cause?
