Data gateway - Change Primary

[mancio]

Hello,

I'm using one gateway cluster with a two gateway that working in fail-over mode.

Gateway Cluster:

- Gateway A (primary)

- Gateway B (fail-over secondary)

now I need to set Gateway B as primary and delete Gateway A.

is there a powershell command to set Gateway B as primary?

What is the correct procedure to follow?

Thanks

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).

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.

do you mean as activity complets for takeover of primary gateway over B, we will see as follows:

- Gateway A (fail-over secondary)

- Gateway B (primary)

There's no failover. All cluster members share the load if you specify it with the checkbox. Primary/Anchor is purely cosmetic.
