promise TX2 ata raid utilities?

[Sean Ellis]

Hello,

I'm taking care of a computer now with a promise tx2 controller card and
two 40G hard drives as a raid1 array. The machine is running
4.10-PRERELEASE freebsd.

I'm wondering if anyone knows if there are utilities to monitor the
'health' of such a raid array? I'm also wondering if there are any
recommendations for a relevant resource about managing the array.
Something along the lines of the 'what to do in case of disaster' 
stuff that accompanies the vinum docs,

thanks,

Sean
