In PRIMECLUSTER, the administrative LAN is used to handle the split-brain.
For faster and more accurate split-brain handling, make sure to configure the administrative LAN when configuring the Shutdown Facility.
When configuring the administrative LAN in the Shutdown Facility, the public LAN can be used as well. However, due to network load, using the public LAN may require a longer time to handle the split-brain. For this reason, using the administrative LAN is highly recommended.
