Add a SCSI Device to a Virtual Machine in the vSphere Web Client
To use peripheral SCSI devices, such as printers or storage devices, you must add the device to the
virtual machine. When you add a SCSI device to a virtual machine, you select the physical device to
connect to and the virtual device node.
The SCSI device is assigned to the first available virtual device node on the default SCSI controller, for
example (0:1). To avoid data congestion, you can add another SCSI controller and assign the SCSI
device to a virtual device node on that controller. Only device nodes for the default SCSI controller are
available unless you add additional controllers. If the virtual machine does not have a SCSI controller, a
controller is added when you add the SCSI device.
For SCSI controller and virtual device node assignments and behavior, see SCSI and SATA Storage
Controller Conditions, Limitations, and Compatibility.
Prerequisites
Required privileges: Virtual machine.Configuration.Raw device
Procedure
1 Right-click a virtual machine in the inventory and select Edit Settings.
2 On the Virtual Hardware tab, select SCSI Device from the New device drop-down menu and click
Add.
The SCSI device appears in the Virtual Hardware devices list.
3 Expand New SCSI device to change the device options.
4 (Optional) From the Virtual Device Node drop-down menu, select the virtual device node.
5 Click OK.
The virtual machine can access the device.
Add a PCI Device in the vSphere Web Client
vSphere DirectPath I/O allows a guest operating system on a virtual machine to directly access physical
PCI and PCIe devices connected to a host. This action gives you direct access to devices such as high-
performance graphics or sound cards. You can connect each virtual machine to up to six PCI devices.
You configure PCI devices on the host to make them available for passthrough to a virtual machine. See
the vSphere Networking documentation. However, PCI passthroughs should not be enabled for ESXi
hosts that are configured to boot from USB devices.
When PCI vSphere DirectPath I/O devices are available to a virtual machine, you cannot suspend,
migrate with vMotion, or take or restore Snapshots of such virtual machines.
Prerequisites
n
To use DirectPath, verify that the host has Intel Virtualization Technology for Directed I/O (VT-d) or
AMD I/O Virtualization Technology (IOMMU) enabled in the BIOS.
