KBeau, What you will do is power down the server and replace the controller.  Once that is finished install the drives and boot to to the Perc 6/i controller (Ctrl_r) from there you should see the configuration.  Highlight the controller on main page and hit F2, then select Foreign Config.  From that screen IMPORT the foreign Config.  After that the array should be recovered and showing Optimal.  Boot up and verify functionality and data integrity.  Let me know how it goes.
Hello - I have to swap out a PERC 6/i Integrated card on my PE1950 box.  Are there any special instructions I should follow?  I couldn't seem to get anything from the documentation I found.  Is it just a simple swap and the system will recognize the new controller upon boot up? Thanks! KBeau
