VBS start and stop operations now feature two important enhancements:
The vbssvc -start and vbssvc -stop commands are interactive and allow you to start or stop the virtual business service even if one of its tiers is in UNKNOWN state.This is useful if a disaster occurs in one of the tiers and you still want to continue operations on the remaining tiers with a single click or a single command.
The VBS start and stop operations now perform a quick pre-validation to verify if all tiers are reachable. This prevents unreachable tiers from being undetected and causing the operation to hang. If the pre-validation check determines that any tier is unreachable, the operation fails and the tier state is correctly marked as UNKNOWN. If you wish to restart the operation ignoring the unreachable (UNKNOWN state) tiers, you can re-run the start or stop operation.
