You can change the bus number and unit number of a virtual machine hard disk.

If the virtual machine uses fast provisioning, power off the virtual machine. Non-fast-provisioned virtual machines support editing virtual machine hard disks while the virtual machine is running.


Click My Cloud.


In the left pane, click VMs.


Select a virtual machine, right-click, and select Properties.


On the Hardware tab, select a new size, bus number, and unit number in the Hard Disks section and click OK.
