Using and Configuring Virtual Media 195
Linux-Based Systems
On Linux systems, the virtual media drives are not configured with a drive
letter. Depending on the software installed on your system, the virtual media
drives may not be automounted. If your drives are not automounted,
manually mount the drives.
Using Virtual Flash
The DRAC 5 provides persistent Virtual Flash—16 MB of flash memory that
resides in the DRAC 5 file system that can be used for persistent storage and
accessed by the system. When enabled, Virtual Flash is configured as a third
virtual drive and appears in the BIOS boot order, allowing a user to boot from
the Virtual Flash.
NOTE: To boot from the Virtual Flash, the Virtual Flash image must be a bootable
image.
Unlike a CD or floppy drive that requires an external client connection or
functional device in the host system, implementing Virtual Flash only
requires the DRAC 5 persistent Virtual Flash feature. The 16 MB of flash
memory appears as an unformatted, removable USB drive in the host
environment.
Use the following guidelines when implementing Virtual Flash:
• Attaching or detaching the Virtual Flash performs a USB renumeration,
which attaches and detaches all Virtual Media devices, respectively (for
example, CD drive and floppy drive).
• When you enable or disable Virtual Flash, the Virtual Media CD/floppy
drive connection status does not change.
NOTICE: The Detach and Attach procedures disrupt active Virtual Media read and
write operations.
Enabling Virtual Flash
To enable Virtual Flash, open a command prompt, type the following
command, and press <Enter>:
racadm config -g cfgRacVirtual -o
