That's interesting, there are two RAID arrays.  The machine has been 
shutdown since my last email, and now raidctl says wd0a is a 
component of raid7 and wd1a is a component of raid0.

# raidctl -s raid0
Components:
           /dev/wd1a: optimal
          component1: failed
No spares.
Component label for /dev/wd1a:
   Row: 0, Column: 0, Num Rows: 1, Num Columns: 2
   Version: 2, Serial Number: 2013001, Mod Counter: 166
   Clean: No, Status: 0
   sectPerSU: 128, SUsPerPU: 1, SUsPerRU: 1
   Queue size: 100, blocksize: 512, numBlocks: 39100160
   RAID Level: 1
   Autoconfig: Yes
   Root partition: Yes
   Last configured as: raid0
component1 status is: failed.  Skipping label.
Parity status: clean
Reconstruction is 100% complete.
Parity Re-write is 100% complete.
Copyback is 100% complete.

raid0 has the highest Mod Counter value.  Does that mean it's the 
"correct" one and I should unconfigure raid7, add wd0a as a hot spare 
to raid0 and start a reconstruction of raid0?
