Connect-VIServer -Server vc3.example.com -User 'MyAdministratorUser' -Password 'MyPassword'

Establish a connection to the local SRM server by providing credentials to the remote SRM site.

$srmConnection = Connect-SrmServer -RemoteUser 'MyRemoteUser' -RemotePassword 'MyRemotePassword'

List all protection groups associated with the SRM server.

$srmApi = $srmConnection.ExtensionData
$protectionGroups = $srmApi.Protection.ListProtectionGroups()

Associate the TestVM virtual machine with the ProtGroup1 protection group and enable the protection for that virtual machine.

$vmToAdd = Get-VM "TestVM"

$targetProtectionGroup = $protectionGroups | where {$_.GetInfo().Name -eq "ProtGroup1" }

$targetProtectionGroup.AssociateVms(@($vmToAdd.ExtensionData.MoRef))

# Enable protection for that virtual machine
$protectionSpec = New-Object VMware.VimAutomation.Srm.Views.SrmProtectionGroupVmProtectionSpec
$protectionSpec.Vm = $vmToAdd.ExtensionData.MoRef
$protectTask = $targetProtectionGroup.ProtectVms($protectionSpec)
while(-not $protectTask.IsComplete()) { sleep -Seconds 1 }
