mpt based devices can be monitored under Linux with the kernel module "mptctl" and the FOSS tool "mpt-status". There seems to be no support under FreeBSD available currently. For more information about mpt have a look at mpt(4).

This driver is used for most HP / Compaq controllers and is (afaik) found in almost all modern SAS/SATA systems provided by HP. As described in http://www.unixadmintalk.com/f41/monitoring-raid-arrays-51889/, you can monitor it via camcontrol:

# camcontrol inquiry da0
pass0: <COMPAQ RAID 1 VOLUME OK> Fixed Direct Access SCSI-0 device
pass0: 135.168MB/s transfers

(This is untested by me, just found it on the net). On http://lists.freebsd.org/pipermail/freebsd-proliant/2006-October/000169.html I also found the relevant strings to look for:

During normal operation of the raid:
# camcontrol inquiry da0 -D
pass0: <COMPAQ RAID 1  VOLUME OK> Fixed Direct Access SCSI-0 device

After removing one of the raid member disks:
# camcontrol inquiry da0 -D
pass0: <COMPAQ RAID 1  VOLUME inte> Fixed Direct Access SCSI-0 device

After re-inserting the raid member disk:
# camcontrol inquiry da0 -D
pass0: <COMPAQ RAID 1  VOLUME reco> Fixed Direct Access SCSI-0 device

And about 45 minutes later:
# camcontrol inquiry da0 -D
pass0: <COMPAQ RAID 1  VOLUME OK> Fixed Direct Access SCSI-0 device

You could also use hpacucli, which can be found at http://people.freebsd.org/~jcagle/. I have no experience with it. So if you have, you can send report or scripts to monitor it to me, so I can include it here (the hint to it was send by Jaimie Sirovich.

+ ### 3ware raid: twa/twe

Install and configure sysutils/3dm. This installs a daemon that provides a webinterface and which is also capable to notify you via e-mail if something happens. This is perhaps the easiest way of monitoring raid in FreeBSD. The other possibility to monitor 3ware raids is via tw_cli.
