Utilisation d'une DMV non existant sur une version sql

Bonjour a tous

Après moultes recherches, temps passé sur des forums et sites, je décide de venir ici présenter ma problématique en espérant avoir des idées lumineuses de votre part
j'explique mon problème , je viens de créé un Rapport SRRS pour le suivi d’état d'espace disque et les différentes partition de mon serveur pour cela je viens d'utiliser ce dernier script

Code :

En exécutant le rapport un message d’erreur apparaît en indiquant un problème sur la DMV "sys.dm_os_volume_stats"
Google est mon ami, et une petite recherche me fait aboutir que la DMV sys.dm_os_volume_stats Nécessite au moins 2008r2 SP1 or je suis sur 2008 R2 (RTM)
alors je pause la question existe t'il une méthode pour injection ou la création de cette DMV sans faire l'installation du corrective vu qu'il s’agit d'un serveur du production qui doit être disponible 24/24 ,SVP n'hésitez pas à me corriger si je dis des bêtises
