Not all blades in the cluster agree about the high availability (HA) status.
When the blades disagree about active/standby state, traffic might be disrupted.
Disabling and enabling blades in a chassis that is configured to use HA Groups can sometimes result in a blade staying in standby even though the other blades in the chassis have gone active.
None.
Disabling/enabling blades in cluster no longer results in inconsistent failover state.
