Bad drive on app4

[Mike McGrath]

We've got a bad drive on app4, this box is scheduled to be removed soon 
but hasn't been yet and, is not under warranty.  I consider this to be 
of emergency in importance, and I will be finding a different location 
to build app4 immediately.  Getting the new app server up is of medium 
risk but not having it up for tomorrow is of HIGH risk as it would cause 
all mirror traffic to go through app3, and only app3.
