Shelve and Unshelve a WCU
When a WCU is shelved it is disconnected from its car, if connected, and removed from its resource group, if any. In addition all active measure tasks are set to stopped pending and the system label shelving_in_progress is attached. This label will remain until all tasks for the WCU have status Stopped and all gathered measure data is uploaded to the portal after of which the label is replaced by the system label shelving_done. In this final stage it is also possible to unshelve the WCU using the corresponding button and thus removing the shelving_done-label. Note that when a WCU either has shelving in progress or is shelved it is no longer possible to add new measure tasks.
It is possible to Unshelve one or multiple WCUs using the Unshelve button in the Vehicles-tab. If the choices does not apply to the set of selected resources the button is disabled. It is possible to unshelve a WCU from any of the existing shelving states; shelved, shelving refurbish in progress or refurbished. Note that the user must have the permission wcu:shelving:write to be able to perform this operation.
As of version 2.96.0, it is possible to shelve one or multiple WCUs using the Shelve button. The button is disabled if no row is selected or if the selected WCU is not in the In Operation state. Once the shelving process begins, both the Shelve and Unshelve buttons will be disabled until the process is complete. Note that users must have the wcu:shelving:write permission to perform this operation.
