Master Node Recovery
The VectorH High Availability (HA) Option for the Redhat Cluster Suite can be used to configure failover of the VectorH Master Node to a designated Secondary Master Node. An existing slave node is configured to act as a Secondary Master Node during HA setup.
When the Master Node fails, the HA failure mechanism attempts to reconfigure to remove the node from the node list and start the Secondary Master Node.
