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.


  1. Click My Cloud.
  2. In the left pane, click VMs.
  3. Select a virtual machine, right-click, and select Properties.
  4. On the Hardware tab, select a new size, bus number, and unit number in the Hard Disks section and click OK.
