In this procedure, you will reattach the disk mirrors of the Enterprise 450 or Sun Fire 
V880 DNCS. If you have upgraded an Enterprise 250 DNCS, you can skip this 
procedure. 

Additionally, do not perform this procedure unless you are certain that the upgrade 
has been successful. After the mirrors are reattached, you cannot easily roll back to 
the previous system release; instead, you will have to restore your system using your 
latest file system and database backup tapes.

system begins to reattach the disk mirrors. 

5  Type y and press Enter at prompt. The mirrState displays the message Are you 

sure that you want to proceed?
