Hello,
i use an Asrock Rack mainboard and when i connect to SOL via ipmitool, i verified i have connection plus redirection as i am able to operate UEFI/BIOS setup and see POST. The last thing i see is “Welcome to GRUB”.
The system then continues to successfully boot into TrueNAS Scale but no serial console is available via SOL. I would like to have the console redirection working as the IPMI KVM is a little bit tedious over mobile connections.
In Settings/Advanced/Console, Serial Console is enabled and ttyS0 selected with 115200 (which matches with BMC settings).
I checked the /etc/default/grub.d/truenas.cfg and found
Blockquote
GRUB_CMDLINE_LINUX_DEFAULT=“libata.allow_tpm=1 amd_iommu=on iommu=pt kvm_amd.npt=1 kvm_amd.avic=1 intel_iommu=on zfsforce=1 nvme_core.multipath=N drm.edid_firmware=edid/1920x1080.bin”
GRUB_SERIAL_COMMAND=“serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1”
GRUB_TERMINAL_INPUT=“console serial”
GRUB_TERMINAL_OUTPUT=“gfxterm serial”
GRUB_CMDLINE_LINUX=“console=tty1 console=ttyS0,115200”
When i look at Using a Serial Console with Linux, GRUB, SysLinux + Understanding Serial Configuration, i found that it should be
-console=tty0 (?)
-115200n8 (?)
Can you advise how to get the TrueNAS console over SOL working?
