    279279and if so, (c) what action or actions are useful. If the resource will change states without explicit experimenter action, what is the expected next state on success.

    281 Note that states represent the AM's view of the operational condition of the resource. This state may be wrong due to faulty information at the AM.
     281Note that states represent the AM's view of the operational condition of the resource. This state represents what the AM has done or learned about the resource, but experimenter actions may cause failures that the AM does not know about.
    282282
    283283Any operational action may fail. When this happens, the API method should return an error code. The sliver may remain in the  original state. In some cases, the sliver may transition to the `geni_failed` state.
     
    289289GENI defined operational states:
    290290 - `geni_notready`: A final state. The resource is not usable / accessible by the experimenter, and requires explicit experimenter action before it is usable/accessible by the experimenter. For some resources, `geni_start` will move the resource out of this state and towards `geni_ready`.
    291  - `geni_configuring`: A wait state. The resource is in process of changing to geni_ready, and on success will do so without additional experimenter action. For example, the resource may be powering on.
     291 - `geni_configuring`: A wait state. The resource is in process of changing to `geni_ready`, and on success will do so without additional experimenter action. For example, the resource may be powering on.
     292 - `geni_stopping`: A wait state. The resource is in process of changing to `geni_notready`, and on success will do so without additional experimenter action. For example, the resource may be powering off.
    292293 - `geni_ready`: A final state. The resource is usable/accessible by the experimenter, and ready for slice operations.
    293294 - `geni_ready_busy`: A wait state. The resource is performing some operational action, but remains accessible/usable by the experimenter. Upon completion of the action, the resource will return to `geni_ready`.
    294  - `geni_failed`: A final state. Some operational action failed, rendering the resource unusable. An administrator action, undefined by this API, may be required to return the resource to operations.
     295 - `geni_failed`: A final state. Some operational action failed, rendering the resource unusable. An administrator action, undefined by this API, may be required to return the resource to another operational state.
    295296
    296297GENI defined operational actions:
    297298 - `geni_start`: This action results in the sliver becoming `geni_ready` eventually. The operation may fail (move to `geni_failed`), or move through some number of transition states. See EG booting a VM.
    298  - `geni_restart`: This action results in the sliver becoming `geni_ready` eventually. The operation may fail (move to `geni_failed`), or move through some number of transition states. During this operation, the resource may largely remain accessible/usable. Dynamic state associated with this resource may be lost by performing this operation. See EG re-booting a VM.
     299 - `geni_restart`: This action results in the sliver becoming `geni_ready` eventually. The operation may fail (move to `geni_failed`), or move through some number of transition states. During this operation, the resource may or may not remain accessible. Dynamic state associated with this resource may be lost by performing this operation. See EG re-booting a VM.
    299300 - `geni_stop`: This action results in the sliver becoming `geni_notready` eventually. The operation may fail (move to `geni_failed`), or move through some number of transition states. See EG powering down a VM.
