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

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

Sufficient privileges to edit the virtual machine.

1

Right-click on a virtual machine and select Edit Settings.

2

Select the Hardware tab.

3

Click Add.

4

Select Hard Disk and click Next.

5

Proceed through the wizard, selecting options that suit your needs.

6

In the Advanced Options page > Virtual Device Node section, select an unused SCSI Bus number.

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.

7

On the Ready to Complete page, click Finish.

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