The following table outlines tested design and component failure scenarios with Metro Volume enabled with vSphere HA.
Event scenario | Metro Volume behavior | vSphere HA behavior |
Uniform: Outage of non-preferred Metro Volume | Preferred Metro Volume remains available | None. VMs have uniform paths to surviving preferred Metro Volume. |
Non-uniform: Outage of non-preferred Metro Volume | Preferred Metro Volume remains available | vSphere HA restarts impacted VMs on preferred Metro Volume. |
Uniform: Outage of synchronous replication link | Preferred Metro Volume remains available | None. VMs have uniform paths to surviving preferred Metro Volume. |
Non-uniform: Outage of synchronous replication link | Preferred Metro Volume remains available | vSphere HA restarts impacted VMs on preferred Metro Volume. |
Uniform: Outage of preferred Metro Volume | Non-preferred Metro Volume becomes unavailable. Manually promote non-preferred Metro Volume. | vSphere HA attempts to restart impacted VMs if a Metro Volume becomes available in time. |
Non-uniform: Outage of preferred Metro Volume | Non-preferred Metro Volume becomes unavailable. Manually promote non-preferred Metro Volume. | vSphere HA attempts to restart impacted VMs if a Metro Volume becomes available in time. |
