LSI MegaRaid monitor HOW-TO

12 Aug 2005

      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 package is a
directory called Utilities/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 2,3,4,5.

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 do a
consistency check once a month at 1:00am. This makes 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.
