In hindsight, I guess it is gutsy.  Our assumption was that OSs were 
solid enough these days that we could get away with doing this type of 
thing.

Solaris (from my understanding) is probably the best system in the world 
for handling FC environment, so this is disappointing news.

Will look at those, thx.

Yea, we run nearly 60 servers in this way.  I think NFS is the right answer.

We've thought of using snapshots and send/recv, but have backed away 
from it for a few reasons.  A) It doesn't perform any real validation on 
the data as mentioned in a previous email.  B) As stated all over the 
place, this should not be used in place of a proper backup environment.  
BUT, it's probably more reliable then what I'm trying to do now.

Thank you for your time, I appreciate it greatly.
