How to monitor an LSI MegaRAID controller within OpenFiler

Use wget to download the MegaCLI package from LSI you need the MegaCLI - Linux version

Extract the files eg.

rpm2cpio MegaCli-8.00.11-1.i386.rpm | cpio -idmv

and make sure you move the binaries into /opt/MegaRAID/MegaCli/

cd /etc/cron.hourly

Create a new hourly script to check the drives and send an email alert if there's a problem

vi MegaRAIDcron

cd /opt/MegaRAID/MegaCli
./MegaCli64 -AdpAllInfo -aALL | grep "Degraded" > degraded.txt
./MegaCli64 -AdpAllInfo -aALL | grep "Failed" >> degraded.txt
cat degraded.txt | grep "1" > /dev/null
if [[ $? -eq 0 ]];
./MegaCli64 -LdPdInfo -aALL | mailx -s 'Degraded RAID on '$HOSTNAME -r $HOSTNAME@youremail.com alert@youremail.com


chmod 775 MegaRAIDcron

You can test this works by running the script manually but replace the grep "1" on the 5th line with grep "0" so it'll send an alert if there are 0 failures instead of 1. Don't forget to change it back!

This script was adapted from this post on the Openfiler forums.

You can also send a daily/weekly overview email (to make sure it's still working!) by creating a similar file as above in the cron.daily or cron.weekly folder.

cd /opt/MegaRAID/MegaCli
./MegaCli64 -LDInfo -Lall -aALL >/tmp/MegaCli64.txt
mailx -s 'RAID INFO on '$HOSTNAME -r $HOSTNAME@youremail.com -v -a /tmp/MegaCli64.txt you@youremail.com
