Send email alerts if Adaptec raid fails in Linux

Filed under: linux — Tags: , , , , — admin @ 10:56 am

For Adaptec Raid you need arcconf tool to check the raid status, you can install it based on the instructions provided on this link (For Debian) :
After you have arcconf installed, create /usr/bin/raidcheck with following content and make it executable :

RESULT=$(arcconf GETCONFIG 1 | grep Status | grep -v "Not Installed" | grep -v Optimal)
if [ -n "$RESULT" ]; then
    wget -O /dev/null
    else echo "Raid is OK"

Note : In my script I have chosen to use a php script on another server to send the alert, this way I wont need to install a mail server on every server which I am monitoring. you can do the same or change the wget line to whatever you want.
Put the script in the cron to check the raid status every 12 hours :

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

Send email alerts when HP Proliant RAID fails in Linux

Filed under: linux — Tags: , , , , , , , — admin @ 7:51 pm

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
