The DR plan should be tested by someone who did not write it. I will remember that you need to do "this" that I did not write down. Someone else did not. Your plan may need to be executed by someone else if the network administrator was in the data center and is now unavailable.
The other thing is what would you do if you have your equipment but loose key personnel overnight. I have a friend who learned early one morning that his network administrator had been a bad boy. Net Admin was in custody and the FBI wanted every computer he touched, i.e. all of the servers. The FBI took images of the servers and Net Admins workstation and laptop. They were down for a day. Net Admin? He won't be touching a computer ever again.
