Simple script that runs the 3ware app and dumps it to a file, then mails it, then deletes it. and crontab to do it daily.
[root@vz1 ~]# more /root/raid.sh
/usr/local/sbin/tw_cli /c0/u0 show > /root/raidstatus.txt
/usr/local/sbin/tw_cli /c1/u0 show >> /root/raidstatus.txt
mail -s "DAILY RAID STATUS 1.1.1.1" email@yourdomain.com < /root/raidstatus.txt
rm -rfv /root/raidstatus.txt > /dev/null 2>&1
I have a root contrab to run it at midnight daily:
0 0 * * * /root/raid.sh > /dev/null 1>&1
Note: just be sure to set the correct /c0/u0 for your specific instance and change the IP as well as well as your email.
