Virtual Media operating system information
This section describes the operating system requirements to consider when you are using the iLO
Virtual Media features.
Operating system USB requirement
To use Virtual Media devices, your operating system must support USB devices, including USB
mass storage devices. For more information, see your operating system documentation.
During system boot, the ROM BIOS provides USB support until the operating system loads. Because
MS-DOS uses the BIOS to communicate with storage devices, utility diskettes that boot DOS will
also function with Virtual Media.
Using Virtual Media with Windows 7
By default, Windows 7 powers off the iLO virtual hub when no Virtual Media devices are enabled
or connected during boot. To change this setting, use the following procedure:
1.
Open Device Manager.
2. Select View
→Devices by connection.
3. Expand Standard Universal PCI to USB Host Controller to display the USB devices, including
the Generic USB Hub.
The Generic USB Hub option is the iLO virtual USB hub controller.
4. Right-click Generic USB Hub and select Properties.
5. Click the Power Management tab.
6. Clear the Allow the computer to turn off this device to save power check box.
Operating system considerations: Virtual Floppy/USB key
•
Boot process and DOS sessions—During the boot process and DOS sessions, the virtual floppy
device appears as a standard BIOS floppy drive (drive A). If a physically attached floppy
drive exists, it is unavailable at this time. You cannot use a physical local floppy drive and a
virtual floppy drive simultaneously.
•
Windows Server 2008 or later and Windows Server 2003—Virtual Floppy/USB key drives
appear automatically after Windows recognizes the USB device. Use the virtual device as
you would use a locally attached device.
To use a Virtual Floppy as a driver diskette during a Windows installation, disable the
integrated diskette drive in the host RBSU, which forces the virtual floppy disk to appear as
drive A.
To use a virtual USB key as a driver diskette during a Windows installation, change the boot
order of the USB key drive. HP recommends placing the USB key drive first in the boot order.
•
Windows Vista—Virtual Media does not work correctly on Windows Vista if you are using
Internet Explorer 7 with Protected Mode enabled. If you attempt to use Virtual Media with
Protected Mode enabled, various error messages appear. To use Virtual Media, select
Tools
→Internet Options→Security, clear Enable Protected Mode, and then click Apply. After
you disable Protected Mode, close all open browser instances and restart the browser.
•
Red Hat and SUSE Linux—Linux supports the use of USB diskette and key drives.
Changing diskettes
When you are using a Virtual Floppy/USB key on a client machine with a physical USB disk drive,
disk-change operations are not recognized. For example, if a directory listing is obtained from a
floppy disk, and then the disk is changed, a subsequent directory listing shows the directory listing
for the first disk. If disk changes are necessary when you are using a Virtual Floppy/USB key,
make sure that the client machine contains a non-USB disk drive.
