I'm looking to do a bit more monitoring of my 3ware 9550 with smartd, and wanted to see what others were doing with smart for monitoring 3ware hardware.
Do you have the smartd.conf configured to test, or simply monitor health status? Are you monitoring the drive as centos sees it (/dev/sdX) or are you using the 3ware /dev/twaX for monitoring?
Opinions and discussions are welcome :-P

This is my smartd.conf for monitoring drives on a 9550SX:
/dev/twa0 -d 3ware,0 -H -m root /dev/twa0 -d 3ware,1 -H -m root /dev/twa0 -d 3ware,2 -H -m root /dev/twa0 -d 3ware,3 -H -m root
Using smartctl is similar:
# smartctl -Hd 3ware,0 /dev/twa0
It's straightforward to do testing with smartctl, but the above -H/--health output gives you some warning that things aren't right before the drive fails, especially the later lines of output (e.g. Current_Pending_Sector, Offline_Uncorrectable). I run it as a weekly cron job.

Do you ever run the long/short tests? These are mentioned in the smartd.conf 3ware examples.
I've never enabled them.

No, I scheduled the selftest through the 3ware controller itself, but it's been so long since I set it up, that I would have to get out the manual to remember how to do it.
# /usr/local/sbin/tw_cli show selftest

I don't use smartd against them but I do run smartctl from time to time. I have had issues with using /dev/sdX and now only use /dev/twaX (but I can't really remember what bit me...).

Have you thought about tying tw_cli into nagios? That's one of my round-tuit projects. I'm sure there are already plugins for it, and it seems like you may get better info.

On a somewhat related note. I haven't yet looked into what 3ware does on the SNMP side. Does it include a MIB file? Anyone generating traps on bad disk events?
Not hard to set up your own OID to run a shell script to check disk status, but traps are cooler. :)

I actually did think about doing this, but this is for my home network, and I'm a little too lazy/busy currently to set up nagios for personal use. I might do that a bit later on if I'm feeling frisky, but for now I was just looking for quick-fix type checking. There are plugins for this already as you suggested, but I have no idea how well they actually function.

I run smart tests weekly in a staggered fashion during off hours on my 3ware arrays. Like this:
/dev/twa0 -d 3ware,0 -H -l selftest -l error -o on -S on -s (O/../../1/18|S/../../2/22|L/../../3/01) -m root /dev/twa0 -d 3ware,1 -H -l selftest -l error -o on -S on -s (O/../../2/18|S/../../3/22|L/../../4/01) -m root
I've found that the smart monitors are pretty good about giving me at least some warning about imminent drive failures when I do this.
