Platform: Linux (CentOS 4.2 of at this writing)
Card: 3Ware Escalade 7506-x Series ATA RAID Controller

I'm really into piece of mind when it comes to my server. One of the critical peices is the RAID Controller. I wouldn't operate a mission critical solution without it.

This lil piece of code checks the status and alarm history of the RAID controller and emails it to me daily.

create a file in your /etc/cron.daily directory. We'll call it say "raidhealth"

# 3Ware CLI RAID Report 
# Written for my Escalade 7506-4LP 
# 
# You will need the tw_cli file which you can download free 
# from www.3ware.com - save this file in your /sbin directory 
# 
# File is free for use by all but comes as is with no warranty 
# 

################################## 
# variables that you need to set # 
################################## 

email='you@yourdomain.com'    # email where the reports are sent 

################################## 
#      do not edit below         # 
################################## 

hostname=`/bin/hostname` 

# pipe output from the 3Ware CLI to a text file 
/sbin/tw_cli info c0 > /tmp/raidhealth.txt 
echo "" >> /tmp/raidhealth.txt 
echo "" >> /tmp/raidhealth.txt 
/sbin/tw_cli alarms > /tmp/raidalarms.txt 

# combine that text to one file for reporting 
cat /tmp/raidhealth.txt /tmp/raidalarms.txt > /tmp/raidreport.txt 

# send me a copy of that output via email 
mail $email -s"3Ware RAID health report for $hostname" < /tmp/raidreport.txt 

# now clean up the text files we made 
rm -rf /tmp/raidhealth.txt 
rm -rf /tmp/raidalarms.txt 
rm -rf /tmp/raidreport.txt

Save and quit. chmod 755 this file. Now you'll get daily reports from your server about your 3Ware RAID Controller.

Your daily output will look like:

Nothing fancy, but I like it.

This will also work in most cases:

I've had this running for a while now on a couple of systems with hardware RAID cards and it works very well.

3ware also provides an official tool they call 3DM. It's http based and can alert you of degraded arrays and such.

Q. What does 3ware's 3DM do?
3DM allows you to configure and monitor your storage remotely via a Web browser.
Management features include hot swap capability, error logging, remote configuration, version
details and rebuild pacing. 3DM also alerts you, via email, of critical events such as drive
failures

Whenever this script runs, I get the following:

/etc/cron.daily/raidhealth:

/etc/cron.daily/raidhealth: line 23: /sbin/tw_cli: No such file or directory
/etc/cron.daily/raidhealth: line 26: /sbin/tw_cli: No such file or directory
/etc/cron.daily/raidhealth: line 32: syntax error near unexpected token `newline'
/etc/cron.daily/raidhealth: line 32: `mail $email -s"3Ware RAID health report for $hostname" < '

I assume there is some required software missing, any pointers?
