I am currently using the Intel AXXRAK18E RAID controller with FreeBSD 6.2. The system is working fine, but I would like to get a utility that will monitor the health of the array and notify me when an error occurs. I realize that I can monitor the system log files and determine this, but this does not tell me when the array is healthy, only that an error occurred.

Note: the RAID array shows up as mfi:

crw-r-----  1 root  operator    0,  30 Jan 16  2008 /dev/mfi0
crw-r-----  1 root  operator    0,  80 Jan 16  2008 /dev/mfid0
crw-r-----  1 root  operator    0,  81 Jan 16  2008 /dev/mfid0s1
crw-r-----  1 root  operator    0,  83 Jan 16  2008 /dev/mfid0s1a
crw-r-----  1 root  operator    0,  84 Jan 16  2008 /dev/mfid0s1b
crw-r-----  1 root  operator    0,  85 Jan 16  2008 /dev/mfid0s1c
crw-r-----  1 root  operator    0,  86 Jan 16  2008 /dev/mfid0s1d
crw-r-----  1 root  operator    0,  87 Jan 16  2008 /dev/mfid0s1e
crw-r-----  1 root  operator    0,  88 Jan 16  2008 /dev/mfid0s1f

Given manual for mfi sysutils/amrstat may be of help
It is actually made by lsi, maybe http://www.lsil.com/ has some linux management tool (fuven half-gigabyte linux emulation + X11

I wonder what is that "device removal" mentioned in manual page. I know mlxcontrol being full featured for mylex control and probably there is something in development...

I ran amrstat but it does not recognize the RAID array. I looked on LSI's site and the only thing I could find related to FreeBSD was a press release from 2005 that says MegaRAID® Adapters Now Feature FreeBSD 5.4 Support.

When I look at LSI's website I see four MegaRAID SATA-300 controllers:

MegaRAID SATA 300-4XLP
MegaRAID SATA 300-8ELP
MegaRAID SATA 300-8X
MegaRAID SATA 300-8XLP

The controller I have is an Intel SRCSAS18E with an AXXRAK18E activation key. Is one of the LSI controllers above compatible with the Intel controller that I have? If so, how did you determine this?

Since the resultant driver and tools are exactly same why should you care?

I tried installing MSM_Linux_2.88-00 from the LSI site. RPM was a prerequisite for this. RPM would not install on my FreeBSD 7 system. I think I will just write a program that monitors the /var/log/message file and alerts me when any messages are generated from the mfi subsystem.

It has to be installed differently.
First you install linux_base_fc
Then you rpm2cpio MSM_Linux*.rpm
Then you locate "management tool" and run it. Odds are not high it will run at all, but at least worth trying.

I ended up doing what I knew would work all along, it's just not an elegant solution. I wrote a script that monitors the /var/log/messages file on a regular basis and pages me if it sees errors from device 'mfid'.

Production versions may perform better.

Linux monitoring tools do not work since ioctls are incompatible.
