Identifying failed hard drive in RAID

hard driveraidstoragesun

I have a server which is running customized version of Debian. It is attached a sun storage raid. It has very limited tools and installing new tools is not allowed. 🙁

This message I see in dmesg:

end_request: critical target error, dev sda, sector 556782970
sd 0:0:0:0: [sda] Unhandled sense code
sd 0:0:0:0: [sda]  Result: hostbyte=0x10 driverbyte=0x08
sd 0:0:0:0: [sda]  Sense Key : 0x4 [current] 
sd 0:0:0:0: [sda]  ASC=0x44 ASCQ=0x0
sd 0:0:0:0: [sda] CDB: cdb[0]=0x28: 28 00 21 2f d5 7a 00 00 08 00
end_request: critical target error, dev sda, sector 556782970

So it seems there is badblock in sector 556782970, but I don't know which hard drive it belongs to so that I can get it replaced.

  • arcconf getlogs command does not reveal any issues with drives.

  • I did arcconf task start 1 logicaldrive 0 verify_fix but this didn't help.

  • I did an e2fsck check. It attempts to fix some inodes but above issue remained. (I assume since its physical issue).

If you actually use arcconf you can see physical drive status like this:

arcconf getconfig 1 PD

Look for drives with Failed state to identify drives that have been marked as failed. For your reference the output would look something like this:

  Device #6
     Device is a Hard drive
     State                              : Failed
