    Why delete A?  You will want to keep your failover setup.

     

    The choreography is as follows:

     

    - Have your recovery key handy. Nothing will work without that.

    - Delete B from the cluster

    - Register B as a replacement Primary in the cluster, kicking out A. 

    - Add the now orphaned A back into the cluster as a secondary gateway

     

    You will not want to do this via Powershell.

Hi,

Gateway A is dead, I need to promote Gateway B to primary.

I have the recovery key.

What is the correct procedure?

 

Thanks

Log in to the management app on B.  Specify "Take over". Select the Primary.  Provide the Recovery key.

 

When successful B will be the new anchor and A will be orphaned.

    Hi Ibendlin,

    if I understand correctly the steps to take are:

    remove node B from the cluster
    uninstall the DataGateway from server B
    rerun the DataGateway setup on server B and perform the takeover

    is this correct?


    Thanks you

      no need to remove B from the cluster first  (but it also doesn't hurt if you do).
