Installer Open Manage sur ESXi

Et voici une fonction Power Shell bien pratique pour installer Open Manage sur un ESXi.
J'ai récupéré la fonction de base sur différents site, puis je l'ai un petit peu modifié :)

Après avoir copié cette fonction dans votre invite, il suffit de lancer la commande suivante pour déployer Open Manage:
installDellOpenManage 'E:\Sources' 'OM-SrvAdmin-Dell-Web-6.5.0-2247.VIB-ESX41i_A01' 'MyCom' 'frves-centreon01' 'frbrs-vc01' 'frbrh-esx73' 'root' 'MyPasswOrd!'

function installDellOpenManage ($DellOMSA, $FolderName, $SNMPCommunity, $SNMPTargetHost, $vCenter, $ESXHost, $User, $Password){
#Input Parameters:
#DellOMSA: Path to the DELL Open Manage folder
#FolderName: Name of the Open Manage folder
#SNMPCommunity: Your SNMP Community
#SNMPTargetHost: Your SNMP Host
#vCenter: The vCenter
#ESXHost: The ESXi host you want
#User: The user to connect to the ESX
#Password: The associated password
#
#Description:
#Install Dell Open Manage and configure the SNMP Community
#
#Exemple: installDellOpenManage 'E:\Sources' 'OM-SrvAdmin-Dell-Web-6.5.0-2247.VIB-ESX41i_A01' 'MyCom' 'frves-centreon01' 'frbrs-vc01' 'frbrh-esx73' 'root' 'MyPasswOrd!'
