The operational status determines when DRL delivers a request to GLA (for example, when GLA is the Available status) and when DRL uses the Unavailability Action for requests (for example, when GLA is in the Unavailable status).
GLA’s Operational Status is dependent on the following items:
When the GLA initializes with the Admin State set to ‘Disabled’, the Operational Status is set to Unavailable. When the Admin State changes from ‘Enabled’ to ‘Disabled’, the Operational Status is transitioned to Unavailable.
When the GLA initializes with the Admin State set to ‘Enabled’, or if the Admin State is changed from ‘Disabled’ to ‘Enabled’, the system begins to monitor resources to determine if it can change its Operational Status.
Once GLA moves into the Available state, the system attempts to answer as many queries as possible and remains available as long as any of the pSBR-B SubResources are also available.
