I wanted to monitor our HP server raid array on Ubuntu 12.04. I am sure that there is a good way of setting this up with Nagios or SMNP – however, I thought I would write a little bash script which emails me if any of the hard drives in the raid array fail. I assume that you have already installed the HP Proliant Support Pack perhaps using these instructions.
To send an email from command line you will also need mailx. This is a virtual package on Ubuntu and I tend to install bsd-mailx. To install it run:
sudo apt-get install bsd-mailx
It will also install Postfix (if this isn’t already setup). When configuring Postfix, I selected “Internet Site” and entered the hostname of the server.
Here is the bash script that I wrote. The indentation seems to have got lost but you should be able to recreate it.
# Email settings
# Current datetime in YYYY-MM-DD_HH-MM-SS
# Make sure the log directory exists.
/bin/mkdir -p /root/harddrive_check/log
if hpacucli ctrl all show config | grep -q “Failed”; then
echo -e “Harddrive Check Run: `date`” > $log_filename
echo -e “\nUsing Command: hpacucli ctrl all show config” >> $log_filename
hpacucli ctrl all show config >> $log_filename
email_subject=”Harddrive Failed On $hostname”
/usr/bin/mailx -s “$email_subject” “$email_recipient” < $log_filename
I then setup a cronjob on the server.
Adding the line:
0 * * * * /root/harddrive_check.sh
I hope this is helpful to someone. Let me know if you know a better way of doing this. Thanks for reading.
