If you look at /usr/lpp/mmfs/samples/expelnode.sample you can use this as a base and install this in /var/mmfs/etc on the cluster manager. You can control which of the two nodes get expelled.
We use it here to send an alert when a node is expelled. There is also "mmexpelnode" which you can force a particular node to be expelled.

Hi, We are in the process of diagnosing a networking issue that is causing 2 of our 6 node GPFS cluster to expel each other (it appears they experience a temporary network connection outage and lose contact with each other). At present it's not consistent which gets expelled by the cluster manager, and I wondered if there was any way to always force a specific node to be expelled in this situation?
