In an environment with multiple availability zones, if a site failure in Region B occurs, the witness appliance in Region B becomes inaccessible. As a result, one fault domain becomes unavailable for the vSAN stretched cluster. To continue provisioning virtual machines in Region A, configure vSAN by using the vSAN default storage policy to force-provision these virtual machines although they will be non-compliant until the witness appliance rejoins Region A.You perform this operation only when multiple availability zones are configured in your environment.
