I am using Hyper-V. I added two nodes to an existing cluster. Cluster operates and reports correctly. SCVMM picked up on the new nodes and added them correctly. The nodes themselves and SCVMM all show the OS as 10.0.14393 (2016). I am unable to add VRA’s to the new nodes because Zerto shows the OS as 0.0.0000. I have run the PowerShell scripts manually and they report back 10.0.14393. It seems that somehow Zerto is not updating the OS. Why? Support is actively working on this; I thought I would also post the question here.
