194 Using and Configuring Virtual Media
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.
CAUTION: The Detach and Attach procedures disrupt active Virtual Media read
and write operations.
