Restrictions and cautions
Restrictions
The upgrade to BIOS-5.24 or later from an earlier version on the HDM Web interface for the R4900 G5, R4700 G5, R5300 G5, R5500 G5(Intel), S4703 G5, S2703 G5, B5700 G5, or H3C UniStor X10000 G5 supports only the Forcedly restore method. To retain the user-configured settings in the earlier version, perform the following operations:
a.Export the configuration file of the earlier version.
b.Upgrade to BIOS-5.24 or later by selecting the Forcedly restore method.
c.Import the configuration file of the earlier version after the upgrade.
The upgrade to BIOS-5.31 or later from an earlier version on the HDM Web interface for the R6900 G5 supports only the Forcedly restore method. To retain the user-configured settings in the earlier version, perform the following operations:
a.Export the configuration file of the earlier version.
b.Upgrade to BIOS-5.31 or later by selecting the Forcedly restore method.
c.Import the configuration file of the earlier version after the upgrade.
As from release BIOS-5.53, if you use the AFU tool in the OS to perform an upgrade with the user-configured settings retained, you can retain the core disable number setting configured on the Advanced > Socket Configuration > Processor Configuration > Per-Socket Configuration > CPU Socket 1 Configuration screen. If you upgrade from BIOS-5.52 or an earlier version, the core disable number setting cannot be retained.
Guidelines
To avoid BIOS boot failures, do not upgrade or reset HDM during BIOS boot.
If an iluvatar BI-V150 GPU is connected to the R5300 G5 server, please be cautious when you enable the SR-IOV function for the network adapter, as it will result in the server being able to install only one network adapter in AI serial/parallel mode.

Update suggestions
This version is recommended.
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.
