When a solution updates its ESX agency scope, ESX Agent Manager provisions new ESX agents on new hosts and removes ESX agents from hosts that are no longer in the scope.

When the scope of an ESX agency changes, vSphere ESX Agent Manager detects the change and displays the status of the ESX agents in the scope and operations that are in progress. You can add functions in the solution definition to remediate the issues, or the solution can report the issues so that administrators can fix them manually.

When a solution adds or removes compute resources from the ESX agency scope, the status of the ESX agency changes as the solution works to achieve the goal state of the ESX agency.

Table 1. Status of ESX agency scope changes
Scope Change Current ESX Agency State ESX Agency Status
Add compute resource. Undeployed Unchanged. New ESX agents always start in the undeployed state.
Remove compute resource. Undeployed Unchanged. Old ESX agents that the solution has not removed yet are pending undeployment.
Add compute resource. Disabled Yellow, until the solution deploys the ESX agents on the new compute resource.
Remove compute resource. Disabled Yellow, until the solution undeploys the ESX agents from the compute resource.
Add compute resource. Enabled Yellow, until the solution deploys the ESX agents on the new compute resource, starts the ESX agents, and receives heartbeats.
Remove compute resource. Enabled Yellow, until the solution stops and undeploys the ESX agents from the compute resource.
