|About Vocera Clusters / Network Problems and Clustering|
Before you manually rejoin a split brain, you must decide which node has the database and other files you want to preserve; this machine becomes the new active node in the rejoined cluster. See Geographically Distributed Clusters for additional information.
To manually rejoin a split brain:
The abandoned server enters discovery mode, sees the preserved server, and comes online as a standby node for it. This new standby node then performs a remote restore from the preserved server, which is now the single active node.
The badges that were connected to the abandoned server find the active node and connect to it, because the active node is still in their cluster list.
For Vocera Report Server machines that were connected to the abandoned server, you must check the cluster list, find the active node, and connect to it.
