To run a script in powershell the ExecutionPolicy needed to be changed since it was set to Restricted and needed to be :RemoteSigned
You may need to also make sure you are in "powershell" instead of "powershell (x86))"
1) checking the policy first to make sure that it is the issue:
PS C:\Program Files (x86)\Quest Software\NetVault Backup\scripts\HyperV> Get-ExecutionPolicy
Restricted
(make sure you are using the correct path. If you have an older install, the path may be "BakBone Software" instead of "Quest Software")
2) setting the policy correctly:
PS C:\Program Files (x86)\Quest Software\NetVault Backup\scripts\HyperV> Set-ExecutionPolicy -Scope LocalMachine RemoteSigned
Change in strategy execution
The implementation strategy can protect you against scripts that you consider unreliable. By changing the
implementation strategy may expose you to security risks described in the help section
about_Execution_Policies. Would you change the implementation strategy?
[Y] Yes [N] No [S] Suspend [?] Help (the default is "Y"): y
After the modification, the plugin will be able to see the VMs.
Resolution 2
Please perform the following step below.
Enabling communication between Host in clustered environment. After installing and configuring a NetVault Backup Virtual Client, you must ensure that the Virtual Client can manage all Hosts included in a cluster and that each Host can access any other Host included in the cluster.
1) From a command prompt on the first Host included in the cluster, type:
cd \util
The default installation directory is C:\Program Files (x86)\Quest software\NetVault Backup\util or the
corresponding directory under C:\Program Files.
2) For each Host that was added to the Virtual Client, type:
nvclientaccess -client -password
where is the name of the next Host that was added to the Virtual Client and is the same one that you specified when you added the client to the NetVault Backup Server.
For example, if you have two Hosts, run nvclientaccess -client password
on Host1 with as Host2.
3) Repeat these steps for every Host included in the cluster
