Re: System exposure to disk outages w/9337 in separate ASP

Any other failure would cause a system failure.  No you can not expect that

You would not want to try to reconfigure in the event of a failure.  You 
would be breaking more stuff than you would be fixing.  Among other things, 
you would have to do a RCLSTG, because the system directory is kept in the 
system ASP.
