mfiutil reports "PSTATE 0x0020" new drive state

[Charles Owens]

  Hmm... the problem appears to have resolved itself.  After a few hours 
the new drive seems to have gone back into the array, and the original 
hot spare drive put back into hot-spare state.

So I'm interpreting state 0x0020 to therefore mean something like "hang 
on while I use this new drive to automatically put everything back as it 
was before the failure".  Is this correct?

Thanks,
Charles
