How do I test failover in a Unified Failover configuration?
Solution:

The following criteria is used for failover in a Unified Failover configuration and can be used to test failover.

  • A link failure on an interface configured for failover will cause failover to occur.

  • On a standby box, if the administrator configures "force master", then it should make an attempt to become the Master box.

  • A Master box (with "Force Master" not set) should failover if it finds that one of its peer has "Force Master" set.

  • A Master box (with "Force Master" not set) should failover if it finds that one of its peer with "Force Master" has become Master and the peer's Node ID is smaller.

  • If any of the supported service fails on a Master box, then it fails over to Standby mode.

  • If a service goes down on a Master, ForceMaster box, then it fails over and becomes standby.
