You can check command show system and that will help to show all information about the system, any unhealthy component present in the system.
You can manually delete the Volumes and Vdisks or VDG. That will do the purpose for you. All drive should be back in AVAIL state which means all drives will back to initial state.
If you want to remove all configuration then run the below command,
# restore defaults
Hope this helps!
