In private cloud datacenters, you can create secondary hard disks that are not persistent. This means that when you undeploy the VM or remove the hard disk the platform will delete your hard disks and destroy all data on them.
To add a VM hard disk:
Go to Virtual datacenters → edit VM → Storage
Click the add button at the top right of the tab
Select Assign virtual disk and complete the dialog

When there is more than one controller, to identify the controller and bus number, the platform displays the bus number as a suffix to the controller. Access ESXi to confirm bus numbers that are not displayed
