Exchange 2010 DAG

I will be testing DAG HA in a production environment. We have a production site and a DR site. Replication across both sites are good. Its a 4 node dag with 2 mailbox servers in the prod site and 2 in the DR site. I will run the startdagmaintenance.ps1 script on server 1 which will active the passive copies locally to server 2 according to the DB preferences. But the question is can I also run the startdagmaintenance.ps1 on server 2 also so that the passive DBs will activate on server 3 and 4 in the DR site since both servers in production are in maintenance mode. Can both server 1 and 2 be put in maintenance mode.
