Using Virtual Media

Virtual Media overview

In this section on Virtual Media, the remote console for HP Server Console Switches with Virtual Media is
only available if the console switch is tiered underneath an HP IP Console Switch with Virtual Media.
The console switch enables you to connect shared media to a server using a USB connection. This
capability enables you to manage systems more efficiently by performing operating system installation,
operating system recovery, program installation, file transfers, and BIOS updates from the local or remote
console.
You can connect Virtual Media directly to the console switch using one of the USB ports located on the
rear of the console switch. In addition, you can connect Virtual Media from any remote workstation that is
running the HP IP Console Viewer and is connected to a server using an HP IP Console Switch with Virtual
Media. All USB ports of a local console are assigned to a single Virtual Media session and cannot be
mapped independently to different servers.
To open a Virtual Media session with a server, you must first connect the server to the console switch
using an interface adapter with Virtual Media and establish a local console session.
Using a console switch with Virtual Media, you can map a removable mass storage device or a CD/DVD
type device on the console as a virtual drive on a target server. You can also add and map an .iso or
floppy image file on the local client as a virtual drive on the target server if you are using the HP IP
Console Viewer.
Limitations of using USB 2.0 composite devices with Virtual
Media
The default functionality for Virtual Media for a USB 2.0 interface adapter with Virtual Media capability is
the composite high-speed USB 2.0 capability of the USB protocol. The BIOS and particular operating
systems and installation programs of various target servers do not support composite USB 2.0 devices. If
your target server BIOS or operating system does not support such devices, then you must perform one of
the following actions:
•
Purchase a PS2 interface adapter with Virtual Media and map a single Virtual Media device, which
operates in standard USB 2.0 mode.
•
Disable the USB 2.0 function of the USB 2.0 interface adapter with Virtual Media from the console
switch local OSD, enabling the interface adapter to operate in USB 1.1 mode.
AMD Opteron™-based HP ProLiant servers and Red Hat Enterprise Linux 4 (before Update 5) do not
currently support composite USB 2.0 devices. However, the target server BIOS for Intel®-based HP
ProLiant G4 and later servers support composite USB 2.0 devices. If the server BIOS supports USB 2.0
composite devices, but the operating system installation program does not, a failure occurs when the
keyboard and mouse control is switched from the BIOS to the installation program.
