Send email alerts if PERC H200 raid fails in Linux

Filed under: Debian,linux — Tags: , , — admin @ 11:18 pm

Recently I have bought a Dell PowerEdge R210 server which is equipped by PERC H200 raid controller.
As I have setup a raid 1 on this server, I needed to monitor its raid status, Here is what I did :
First you need “sas2ircu” utility which can be found on following website :
Running “sas2ircu 0 STATUS” give you following output :

root@x:/# sas2ircu 0 STATUS
LSI Corporation SAS2 IR Configuration Utility.
Version (2013.03.01)
Copyright (c) 2009-2013 LSI Corporation. All rights reserved.

Background command progress status for controller 0...
IR Volume 1
  Volume ID                               : 79
  Current operation                       : None
  Volume status                           : Enabled
  Volume state                            : Optimal
  Volume wwid                             : xxxxxxxxxxxxxx
  Physical disk I/Os                      : Not quiesced
SAS2IRCU: Command STATUS Completed Successfully.
SAS2IRCU: Utility Completed Successfully.

What we are interested in is “Optimal” status. so if Optimal changes to anything, we want to be notified.
You can use the following script to do that (change MAIL variable to your own email address) :

RESULT=`sas2ircu 0 STATUS | grep Optimal`
if [ -z "$RESULT" ]; then
    echo "RAID ERROR ON SERVER" | mail -s 'Raid Error' "$MAIL"
    else echo "Raid is OK"

as always do not forget to test if your server is actually able to send mails and you receive them.
Finally save the script in a file and put it in cronjob. I have chosen to run it every 12 hours :

0 */12 * * * /usr/bin/raidcheck
