Changing gateway nodes on primary

You can add new gateway or remove existing gateway nodes by using the mmchnode command. AFM automatically adjusts the existing filesets to use the latest configured gateways.

You must shut down all the existing gateway nodes and then add or remove gateway by using mmchnode command on a cluster that is running applications on AFM DR filesets. If the gateway nodes are changed while all gateway nodes are active, the gateway nodes might not be responding, or cluster-wide waiters might be observed after you run the mmchnode command. Recycle the active gateway nodes.

It is not possible to remove existing gateway nodes if they are part of a mapping. You can remove the gateway nodes from the mapping by using mmafmconfig command.
Note: Whenever you add or remove a gateway node, ensure that you update the list of IP addresses in the export map on the home.
