When the you start a virtual business service, its associated service groups are brought online in a specified order. The order in which the service groups in a virtual business service come online is determined by the start order defined in Veritas Operations Manager. You can define the start order of service groups using the Configure Dependencies option. You can specify one or more service groups as the child of another service group. Veritas Operations Manager ensures that all child service groups are brought online before the parent service group. If two service groups are not related by the start order, they may come online at the same time. If a service group is configured on a VMware virtual machine, you can also set auto-start for that virtual machine.

The Start virtual business service operation does a quick pre-validation to verify if all tiers are reachable. This detects any unreachable tiers and prevents the operation from hanging. If the pre-validation check determines that any tier is unreachable, the operation fails and the tier state is correctly marked as UNKNOWN. This is useful in a disaster event in one tier, where you can continue to operate on the remaining tiers with a single click operation. If one or more tiers are not reachable and in UNKNOWN state, you can either stop the virtual business service or continue ignoring the unknown tiers

The permission on host of the tier may be explicitly assigned or inherited from a parent organization.
