Hi Tony,

The current behavior is that you can add a spare to a root pool. If the 
spare kicks in automatically, you would need to apply the boot blocks
manually before you could boot from the spared-in disk.

A good alternative is to create a two-way or three-way mirrored root
pool.

We''re tracking the root pool boot issues. If a bug isn''t filed
for this
issue, I will file it.

Thanks,

Cindy

Tony,

A brief follow-up is that the issue of applying the boot blocks
automatically to a spare for a root pool is covered by this
existing CR 6668666. See this URL for more details.
