Windows : Script PowerShell pour stopper une liste de serveurs dans un ordre spécifique - Idéal pour les fermes SharePoint

 Tout fermier SharePoint est confronté un jour ou l’autre à cette question d’arrêt de serveur.

Il est évident que pour une infrastructure Stand Alone (1 serveur) ou Small farm (2-3 serveurs), cela se fera très simplement et ne posera pas de soucis particulier, tant que le serveur SQL est arrété en dernier.

Le cas devient plus délicat lorsqu’on commence à gérer plusieurs Large Farm (plus de 4 serveurs) dans un ou plusieurs DataCenter.

Le script suivant permet donc de stopper les machines, en utilisant la commande standard de Windows “Shutdown /s”, suivant l’ordre donné dans la liste des machines.

Une fois les deux variables de départ enrichies, il vous suffit de lancer une commande PowerShell (en mode Administrateur), avec un compte Administrateur du domaine (ou qui sera administrateur des machines à éteindre).
