Point of information: the large secondard disk array isn't actually in use 
at the moment because we don't really trust it after it ate all our data. 
The data off it is spread across the SAN, the netapp, and backups are now 
in Arts. I'm not convinced we should be trying to replace the array on a 
new mylah.
