Request parameters
The request accepts the following data in JSON format.
| Parameter | Type | Description | Required |
|---|---|---|---|
method | String | The RVC action to start. This value is specified as a combination of the RVC module and method. For example, to turn on maintenance mode for a target you would specify the cluster module and the enable_maintenance_mode method combined as cluster.enable_maintenance_mode. | Yes |
hostnames | String array | The list of node hostnames on which to run the RVC job. | Dependent. Only if no node group or saved filter is provided. |
node_group_name | String | The name of the node group on which to run the RVC job. The RVC job will run on all nodes that are members of the node group. | Dependent. Only if no hostnames or saved filter is provided. |
node_group_id | Integer | The ID of the node group on which to run the RVC job. The RVC job will run on all nodes that are members of the node group. | Dependent. Only if no hostnames or saved filter is provided. |
saved_filter_name | String | The name of the saved filter on which to run the RVC job. The RVC job will run on all nodes that match the saved filter. | Dependent. Only if no hostnames or node group is provided. |
saved_filter_id | Integer | The ID of the saved filter on which to run the RVC job. The RVC job will run on all nodes that match the saved filter. | Dependent. Only if no hostnames or node group is provided. |
