The default stage behavior is to automatically advance through the configured stages. However, you can configure stage behavior for individual stages or for all stages.
The Start Pending Stage option is only available if you used the Advance to Next Stage Manually and Notify When Complete option to stop each stage for manual input before continuing, instead of having the stages complete automatically.
To start a pending stage:
In ZENworks Control Center, click Configuration in the left pane, then click the System Updates tab.
In the Deploying System Updates panel, select the check boxes for an update.
Click Action > Start Pending Stage.
