Hello there, dear Community!
This post is about the issue of failing to identify the iMana 200 virtual DVD-ROM drive for ISO image mounting. Please see more details as your read further down.

ISSUE DESCRIPTION
A client uses the iMana virtual DVD-ROM drive to mount an ISO image. The virtual DVD-ROM drive option is not displayed when F11 is pressed upon board startup.
KEY PROCESS AND CAUSE ANALYSIS
Operation problem
The actual operation sequence is as follows: restart the board, mount the ISO image, and press F11 (this operation sequence is incorrect). The correct operation sequence is as follows: mount the ISO image, restart the board, and press F11.
BIOS settings
If the board is configured with an external USB DVD-ROM drive, check the virtual DVD-ROM drive and physical DVD-ROM drive sequence in the Boot options. If the board is not configured with an external USB DVD-ROM drive, ignore this step. (For R1 servers, check whether CD- or DVD-ROM drive is disabled for BIOS).
Network problem
The VMM 8208 port is disabled, and the image file cannot be transferred.
ISO image problem
The ISO image is not bootable or is damaged.
iMana software problem
Reset or update the iMana software (NOTE: the iMana software used by R1 servers is of version 1.18 or earlier and cannot support virtual media well).
The mainboard USB bus is faulty, and the mainboard needs to be replaced.(NOTE:R1 BH620 blade servers that use PCB of the version .B do not support virtual media.The preceding steps 3–5 apply to scenarios where the OS has been installed but the ISO image mounted cannot be detected. The only difference is that the image can be bootable or non-bootable).
This is all on the issue of failing to identify the iMana 200 virtual DVD-ROM drive for ISO image mounting.
