Disk mirroring
Issue 1.0 December 2003 11
Disk mirroring
The CUE process can be used to automatically add disk mirroring to a nonmirrored
system. However, the CUE upgrade kit used with the procedures in this document cannot
be used to add mirroring to the system.
If the customer has purchased additional disk drives for the purpose of adding mirroring
independent of the CUE process, you must first upgrade the computer using the CUE
nonmirrored upgrade process before you manually add mirroring to the system.

to add mirroring to the system.
