Failover

Failover is the process of passing control of a file system from an FSM on one MDC to a standby FSM on a redundant MDC. When that FSM is for the HaShared file system, Primary status transfers to the redundant MDC along with all the processing that occurs only on the Primary MDC. This includes all the HaManaged FSMs, the Storage Manager processes, and the blockpool server. When an FSM does not relinquish control cleanly, an HA Reset can occur to protect against possible corruption of file system metadata and Storage Manager databases. See Primary Node and Secondary Node. For additional information, see FSM Failover In HA Environments.
