Hi Everyone,

Any ideas of tools that one can use to report errors etc for hardware RAID?

This depends entirely on the hardware and its driver. Some manufactures like 3ware give you a utility to monitor and control the card. Others write information in to /proc or /sys. Others (HP and Dell come to mind) require companion services to be running and might function through SNMP.

If you are unsure you should contact the hardware vendor. It may be the vendor you chose does not fully support Linux, or only supports it in a limited capacity.

I'd have to say that the 3ware tw_cli is the best raid controller interface I've used. The 3dm stuff is okay, but tw_cli puts you in control. If you're looking for a raid card to make management easy, the 3ware cards are definitely the ones to buy.

One neat trick I like to use to monitor a raid array rebuild is:

watch tw_cli info c0

That will give you the tw_cli output, updated every 2 seconds over top of itself..

Although you have an Adaptec card, here's a script for 3ware cards in case anybody finds it useful. It's designed to run from crond so stderr gets sent to the script's user.
