Send email alerts when HP Proliant RAID fails in Linux

As a minimalist person, I am not a fan of running heavy monitoring tools of HP on my server. so I have written a very small bash script to monitor my server RAID status and send me email alerts if it fails.
For this script to work, first you need to install hpacucli (HP Array Configuration Utility) on your server. you can download it from HP website for your Linux distribution.
The script is very easy to understand but you may need to tweak it a little bit to fit your server.
The heart is this line :

hpacucli ctrl slot=1 pd all show

which returns following on my server :

Smart Array P222 in Slot 1

   array A

      physicaldrive 2I:1:1 (port 2I:box 1:bay 1, SATA, 3 TB, OK)
      physicaldrive 2I:1:2 (port 2I:box 1:bay 2, SATA, 3 TB, OK)
      physicaldrive 2I:1:3 (port 2I:box 1:bay 3, SATA, 3 TB, OK)
      physicaldrive 2I:1:4 (port 2I:box 1:bay 4, SATA, 3 TB, OK)

but we only need lines 6-9 which are showing the drives status. It is where you may need to tweak it as you may have more or less drives.
So it may not be 6-9 for you and you may need to change 6,9 in sed command.
Here is the final script :

RESULT=`hpacucli ctrl slot=1 pd all show | sed -n '6,9 p' | grep -v OK`
if [ -n "$RESULT" ]; then
	echo "$RESULT" | mail -s 'Raid Error' "$MAIL"
	else echo "Raid is OK"

Dont forget to change MAIL variable to your own email address.
You may test the script once to make sure your server is able to send emails and you actually 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
