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

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:
Does anyone know of a command line tool ?
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:
