if [ "$DETECTOR" -ne "2" ] 
then

	echo  "`/bin/arcconf getconfig 1`" | mail -s "There is problem with RAID" [email protected]

Of course, you must add it to cron, for example like this:

*/10 * * * * /usr/local/bin/raid_check.sh

This is what: arcconf getconfig 1  command returns:

Bellow command, show information about RAID configuration and status, and also about logical and physical devices.
