hi joe

what kind of raid1 failures are you trying to find/monitor ??

i would just send a test file to disk...and see it i can 
recover the test files from the mirrore'd set

- if your test file does nto show up on the mirror...
  you have to go and check why not

- Some raid monitoring sw ( from various raid posters )
