interpreting scsi errors (RAID)

interpreting scsi errors (RAID)

[Ross Macintyre]

I have seen this error twice now:

Adapter 1 Channel 1 Target 2: Sense Data: errCode=0x71  valBit=1 
segMent=0x00  SenseKey=4  ILI=0  EOM=0  FMRK=0  Address=0x00005A8E 
ASL=0xA  cmdSpec=0x0000  ASC=0x0C  ASCQ=0x00 FRUC Code + Sense Key
Specific=0x8001

I have an LSILogic Megaraid SCSI 320-1, running RAID level5, 4 disks, and
the OS is RedHat8.0.

What I would like, is to be able to understand these messages.
In particular I need to know if there is a hardware error which means that
I can contact the retailer, in confidence, and ask for a replacement, as
the disk is still under warranty.
Any pointers at FAQs or READMEs greatly appreciated,
Thanks in advance,

Ross

That's a non recoverable write error.

All the sense codes are documented in the current SCSI Primary Commands
document at the t10 webiste 

http://www.t10.org/ftp/t10/drafts/spc3/spc3r17.pdf

Although the pointer will change as the standard is revised.

and do you know if there is any way of knowing what might have caused this?

Cheers,
