At my office, we have a server that we suspect its RAID controller (HP Smartarray) is failing. A cold boot, however, does not indicate anything.

Can anyone recommend me a method to stress-test the controller?


Symptoms that makes me suspect a failing controller:

  • Disk access getting slower, queue getting longer
  • Running dmesg on the XenServer console I see many messages similar to this one:

    end_request: I/O error, dev tda, sector 253655584
    

    (the sector number is never the same)

  • When we move the VM to another physical host, we no longer see the above message

  • Running idle (without any running VM), the dmesg no longer emit the above message

A search on Google indicated that the above message is most commonly associated with a failing SmartArray controller.

How can I be sure that the SmartArray controller is failing?
