The NFS server at the home cluster

The NFS server, the mount path, or the IP address at the home cluster can be changed.

The existing AFM filesets on cache must be updated to point to the new target. The home cluster and file system do not change. Therefore, any change can be reflected in the cache cluster by using the mmafmctl failover command with the --target-only option.

However, if you change an NFS server, the new NFS server must be in the same home cluster and must have the same architecture as the existing NFS server in the target path. In other cases, the failover must be performed without the --target-only option. If the target protocol changes from NSD to NFS or vice-versa, the mmafmctl failover command must be used without the --target-only option.
