Does anyone have the slightest clue on how to monitor a LSI MegaRAID 
SCSI 320-1 adapter in a Linux environent?  I've stared myself blind on 
LSI's website trying to find a way.  Preferably a monitoring system that 
can send alerts via e-mail or to a monitoring client on a WinXP system.

First off get this package from LSI.
http://www.lsilogic.com/downloads/license.do?id=2000&did=7776&pid=2411
It is the driver package for SuSe 9.1. In that drive packagte is a
directory called Utilities then MegaMON. In MegaMON is a file named
lsi_v35.tgz. do a tar -xzvf lsi_v35.tgz. This is the monitor app you
will need.
Then do a ./install -Suse. This will install the binaries and install
the startup script of raidmon in /etc/init.d and set itself to start on
the runlevels.
I have modified my raidmon file to include some other items. Below is
mine:
------------------------------------------------------------
#!/bin/sh
#
# chkconfig: 2345 20 80
# description: RAIDMon is a daemon that monitors the RAID subsystem
#               And generates e-mail to root
# processname: MegaServ.
# source function library
. /lib/lsb/init-functions
case "$1" in
  start)
        megadevice="megadev0"
        rm -f /dev/$megadevice 2>/dev/null
        megamajor=`cat /proc/devices|gawk '/megadev/{print$1}' `
        mknod /dev/$megadevice c $megamajor 0 2>/dev/null
        # New check: 10-31-01: Does node exist
        if [ ! -c /dev/$megadevice ]
        then
          echo "
                Character Device Node /dev/$megadevice does not exist.
                Raid Monitor could not be started
                "
          exit 1
        fi
echo -n 'Starting RAID Monitor:'
        startproc /usr/sbin/MegaCtrl -start > /dev/null
        sleep 1 ; MegaCtrl -disMail
        touch /var/lock/subsys/raidmon
        MegaCtrl -enChkCon
        # check consistency on a Saturday at 01:00 very 4 weeks
        MegaCtrl -cons -h01 -w4 -d6
    echo
        ;;
  stop)
        echo -n 'Stopping RAID Monitor:'
        startproc /usr/sbin/MegaCtrl -stop
        megadevice="megadev0"
        rm -f /dev/$megadevice 2>/dev/null
        rm -f /var/lock/subsys/raidmon 2>/dev/null
    echo
        ;;
  restart|reload)
        $0 stop
        $0 start
        ;;
  *)
        echo "RAID Monitor is not Started/Stopped"
        echo "Usage: raidmon {start|stop|restart}"
        exit 1
esac
exit 0
-----------------------------------------------------------------------
Then just start the raidmon. The above changes tell my system to to a
consistency check once a month at 1:00am. This make sure my RAID5 is
working like it should.
Also note there will be a log file of /var/log/megaserv.log.
I use this setup on about a dozen production machines. It works
perfectly. This will work on 32bit and 64bit machines.

Thanks Brad!
I'll give it a try...  I can't find any documentation on the MegaServ 
application though, any tips on where I can find it?
