This chapter describes geo-redundancy switchovers, their triggers, and the auto-arbitration process. It also explains how to perform a manual switchover and update Crosswork Optimization Engine license counts.
Geo redundancy switchovers
A switchover interchanges the active and standby cluster roles after a failure or by manual action.
Auto-switchover triggers
Auto-switchover can follow manual intervention or failures in cluster nodes, intercluster links, or Crosswork Data Gateway services.
How auto-arbitration works
Auto-arbitration coordinates heartbeat and failure detection across peers before triggering a switchover.
Perform switchover manually
Use the Cross Cluster UI to change cluster roles, update DNS entries, synchronize data, and verify cluster status.
Crosswork Optimization Engine license count after a switchover
The Smart Licenses page reflects the correct license count after 24 hours or by 1:00 a.m. after a switchover.
