You can add SCSI controllers to an existing virtual machine by adding hard disks on unused SCSI Bus numbers.

Before you begin

Power off the virtual machine.

About this task

Adding a new hard disk on an unused SCSI Bus number creates a new SCSI controller.


  1. Click Virtual Machines in the VMware Host Client inventory.
  2. Right-click a virtual machine in the list and select Edit settings from the pop-up menu.
  3. On the Virtual Hardware tab, select Add hard disk and select New hard disk from the drop-down menu.
  4. Expand the hard disk to view all options.
  5. In the Virtual Device Node section, select an unused SCSI Bus number from the drop-down menu.

    For example, bus and device numbers 0:0 - 0:15 are used by the initial SCSI controller. The second SCSI controller uses bus and device numbers 1:0 - 1:15.

  6. Click Save.


The new hard disk and new SCSI controller are simultaneously created.
