Update restrictions and guidelines
This version is recommended.
Make sure the software versions are compatible with each other.
To update both HDM2 and the BIOS, update HDM2 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).
As a best practice of bulk update, make sure you can update one server successfully before you update the remaining servers.
