How to perform diagnostics (stress test) on HP Smartarray Controller
- by pepoluan
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?
