Deleting a VMFS datastore
Unlike the unmount operations, the delete operation will destroy all the data on the datastore. Once done, you cannot revert this operation. Hence, make sure to move all the virtual machine data currently on the datastore to another datastore.
How to do it...

Right-click on the datastore to be deleted and navigate to All vCenter Actions | Delete Datastore:
Click on Yes in the Confirm Delete Datastore dialog box:
