Restrictions and cautions
Restrictions
The configuration import function is not available for upgrading the BIOS from a lower version to BIOS-6.00.20 and higher on HDM due to compatibility issues, but is available for upgrades from BIOS-6.00.20 and higher.
To avoid server startup errors, do not use the AFU tool to downgrade the BIOS from 6.00.24 or a higher version to 6.00.23 or a lower version with the user-configured settings retained.
BIOS-6.00.XX does not support EMR processor upgrade or downgrade on dual-processor servers.
Guidelines
To avoid BIOS boot failures, do not upgrade or reset HDM during BIOS boot.
If the system encounters a black screen and cannot boot after the BIOS firmware upgrade and restart, it may be caused due to the HDM firmware not being compatible. To resolve this issue, upgrade the HDM firmware to the version of the corresponding model as shown in Table 10.
Table 10 HDM firmware version for servers
Product model | HDM firmware version |
H3C UniServer R4900 G6 Ultra, R4900/R4900LE G6, R4700/R4700LE G6 | HDM2-1.24 or later |

Update suggestions
This version is optional.
Update restrictions and guidelines
Make sure the software versions are compatible with each other.
To update both HDM and the BIOS, update HDM first.
Make sure the server is running in stable state before the update. That is, the server is powered off or has entered the operating system.
If the server enters the OS before the update, you must power cycle the server for the new firmware to take effect.
If you select the Retain or Restore method to update the BIOS, the update occurs during POST after the server is powered on again. During the update, do not disconnect the power source from the server, or forcedly power off or restart the server.
If you select the Forcedly restore method to update the BIOS, do not disconnect the power source from the server, or power off or restart the server.
Selecting the Restore or Forcedly restore method will restore the default BIOS settings, including restoring the boot mode in the BIOS to the default (UEFI).
During BIOS update with Forcedly restore selected, writing BIOS data, such as restarting the system or saving BIOS configuration from the BIOS setup utility, can cause data write errors. This can lead to BIOS ROM integrity check failures and even system starting failures. If the system prompts Flash Image Broken! System Halt!, forcedly power off the server, and then try to update the BIOS with Forcedly restore selected again.
As a best practice of bulk update, make sure you can update one server successfully before you update the remaining servers.
