3.2.2 Understanding Unplanned Failover
An unplanned failover might occur if the controller in one of the server nodes fails, or if the cable from one controller
node to the JBOD enclosure is accidentally disconnected. The Syncro CS solution is designed to automatically switch
to the other controller node when such an event occurs, without any disruption of access to the data on the drive
groups.
NOTE When the failed controller node returns, the management and I/O
paths of the pre-failover configurations are automatically restored.
