4000000002000000 - DRBD Split Brain

This alarm occurs when the ELAP A and B servers have simultaneous outages or if the three heartbeat paths are lost between the two servers. If either condition occurs, neither server can determine which server has the most recent copy of the database. The first system to recover becomes the HA active system. Manual action is required to determine which copy of the shared data is valid and to resynchronize with the other system.
