Dear list,
I have inherited a CentOS-5 box with a LSI Sata Raid controller. It is configured as a RAID5 w/hot-standby. My concern is that I have no present means of determining the RAID status w/o downing the system and going into the bios to get status. If a disk has failed and brought the standby disk online, I would like to know about it, the day it happens by seeing it in syslog or getting an e-mail message.
The only solution I have found is on the LSI web-site. It is tool called "MegaMon for Linux". It most recent release was in 2005 and it requires that I use their driver. Just the package title gives me chills. It runs as a daemon and is almost constantly polling the h/w .
I would much prefer a simple command line tool that I can wrap a script around and run it under cron.
My questions are:
1. Does anyone know of a command line tool ?
2. Failing a positive response to #1, has anyone any experience with "MegaMon for Linux", good or otherwise ?
Thanks to all, Ray
The h/w is a dual Opteron dual-core system with lots of memory. The relevant dmesg lines and lspci output are shown below:

I would much prefer a simple command line tool that I can wrap a script around and run it under cron.
I did this when I didn't have a Nagios environment or an snmp setup (LSI provides an SNMP monitoring package for it).
Simply use the MegaCLI to query for status of all LD's and grep for failure modes.
Thanks to both of you who replied.
Mr. Vilensky's approach seemed easiest and his google powers exceed mine.
The link he provided was the key. http://www.monitoringexchange.org/cgi-bin/page.cgi?g=2416.html;d=1
The only issue for me was that the megarc URL has been changed. I found the package at: http://www.lsi.com/DistributionSystem/AssetDocument/files/support/rsa/utilit...
Problem solved.
Best to all, Ray

I haven't had a chance to look at MegaMon, but would love to hear your thoughts if you get a chance to play with it.
