There is no trick. If you expose the HBA directly to the VM then you get all the disks. In order to do this, you need to configure passthrough for the device at the host level (host -> configuration -> hardware -> advanced settings). This requires that the VT stuff be enabled in the BIOS on your host - if you don't have this ability, then you're out of luck. Once the device is configured for passthrough on the host, you also have to pass it through to the VM. This is done by 'adding' the PCI device to the VM configuration. At that point, you just have it in the guest as with the other virtual devices.
