aac driver doesn't seem to notice if a drive fails. You'll want to keep
an eye on with it arcconf run via crontab or something as a workaround.
I use
/usr/local/sbin/arcconf GETCONFIG 1 LD | egrep '(name|Status)'
Seems to work fine with FreeBSD other than that. Only other issue I've
had with it, is it takes about 4 minutes to load it's bios in post.

aacli doesn't work with ServeRAID-8k. But sysutils/arcconf does. I think
it's read only tho.
