Cannot control grub2 bootloader from serial console on HP DragonHawk Server Systems
This document (7016509) is provided subject to the disclaimer at the end of this document.
Allowing the timeout to expire, the system will boot correctly.
"Use graphical console" AND "Use serial console"
A text console is picked up automatically then and redirected by the UEFI firmware's vga driver to the serial console.
After that the grub2 menu is accessible from serial console again.
Edit /etc/default/grub and set:
GRUB_SERIAL_COMMAND="serial --unit=0 --speed=115200 --stop=1 --parity=no --word=8"
grub2-mkconfig -o /boot/grub2/grub.cfg
to finally create a new grub2 configuration file.
