DR Failover¶
The VOSS-4-UC system makes use of database replication facilities during normal operation. During a failover, if 50% or more of the service resources are lost, the system will no longer function without manual intervention.
In this case, the following high level process should be followed.
- Display the current cluster topology using cluster status.
- Remove the dead nodes using cluster del <ip>. Power off the deleted node, or disable its Network Interface Card.
- Once the cluster topology is adjusted, the cluster must be reprovisioned using cluster provision.
- Afterward, the cluster status can be rechecked with cluster status.
Refer to the appropriate detailed DR scenarios for the complete sequence of DR steps.
