How to add a new host to WVD hostpool?

I've successfully built two 2 hostpools for testing purposes -- one for shared and one for personalized. The shared one consists of 1 D8s VM and the personal one consists of 5 individual smaller D2s ...

W_Palm : Can you go to PowerShell and run Get-RdsSessionHost for your host pool? Can you see if your session host VM is listed there?

    Braguzz : Is the use case to "expand" the host pool with a few more VMs based on the same image? Or is it to "replace" the host pool with a new number of VMs based off a new image?

     

    To "Expand":

    - Re-run the Provision a host pool Azure Marketplace offering or Create and provision WVD host pool GitHub ARM template.

    - Use the same "rdshNamePrefix".

    - For the number of VMs, enter the new total you would like to have. If you are expanding from 3 VMs to 5 VMs, enter 5.

     

    To replace:

    - You can run the Update existing host pool GitHub ARM template (entering the details for the updated image). or

    - You can run the create templates but provide a new "rdshNamePrefix"( Provision a host pool Azure Marketplace offering or Create and provision WVD host pool GitHub ARM template) then later remove the old VMs

      Christian_Montoya Hi Christian.  I have tried three different ways to add servers to a host pool.  It seems as though it is consstantly failing because of a conflict and I'm assuming because there is another computer there that it's trying to re-create with the same name?  Not sure.  But I've tried manually, Provision a host pool and the arm template and I cannot add more servers to the pool.  This iis essential as we are ready to increase this to a wider audience so we will need to get specifics down on how to expand these pools.  Thank you for your help.

        I have tested this using the arm templates and it works well. Have you changed any parameters since the original deployment?

         

        One thing I noticed is that it appears you have to keep the majority of settings exactly the same as the initial deployment. The ones I have changed successfully using the template are as follows

        - rdshNumberOfInstances (i.e. from 3 to 4)

        - rdshVmSize (Different SKU)

         

        When I tried to us a different upn for the parameters in the 'domain join process'  within the arm template it failed
