Proware external RAID monitoring

[Joseph Gleason]

I have two Proware SIMBOLO SB-3140's hanging off a FreeBSD 4.7 system.
They are external SCSI-IDE RAID enclosures.

Anyone have any idea how I could monitor their RAID status over SCSI?  According to the manufacturer, the devices are supposed to
sound an alarm in the event of a drive failure.  However, that doesn't help me if no one is in the data center paying attention.

I plan on making a nagios plugin once I figure out how to extract the status of the devices.

Ideally, I am looking for some command akin to "atacontrol status".



Relevant dmesg info:
