rx 4640 Display problem with serial console

I have a rx 4640 itanium server with HP-ux 11i v11.23. I can access the MP console. When i boot the server, i see the post after the OS selection i can't see the rest of the boot process until i see the CDE login. This is the message that appear "Console is a serial device no further output will appear on this output device". How do i solve this problem.

your console is set to the serial line.
See this document on how to change it to the VGA screen:


(Selecting Your HP-UX Console for Itanium-based Systems)

Hope this helps!

Hi Sakui,

Using the EFI menus, do the following:

Select Boot option maintenance from the main Boot Manager Menu.

Select Select Active Console Output Devices.

Select the correct output device and deselect others. On the HP Integrity systems, the Select Active Console Output Devices menu looks like this:

EFI Boot Maintenance Manager ver 1.10 [14.57] Select the Console Output Device(s) Acpi(PNP0501,0)/Uart(9600 N81)/VenMsg(PcAnsi)Acpi(PNP0501,0)/Uart(9600 N81)/VenMsg(Vt100)Acpi(PNP0501,0)/Uart(9600 N81)/VenMsg(Vt100+)Acpi(PNP0501,0)/Uart(9600 N81)/VenMsg(VtUtf8)Acpi(HWP0002,700)/Pci(1|1)/Uart(9600 N81)/VenMsg(PcAnsi)Acpi(HWP0002,700)/Pci(1|1)/Uart(9600 N81)/VenMsg(Vt100)Acpi(HWP0002,700)/Pci(1|1)/Uart(9600 N81)/VenMsg(Vt100+)Acpi(HWP0002,700)/Pci(1|1)/Uart(9600 N81)/VenMsg(VtUtf8)* Acpi(HWP0002,700)/Pci(2|0)Acpi(HWP0003,400)/Pci(0|0) Save Settings to NVRAMExit

Understanding Interface Differences Between Itanium-based Systems
Each Itanium-based system has a similar interface with minor differences. You can navigate these menus with the arrow keys or â vâ and â ^â keys, and use the Enter or spacebar key to select and deselect devices. Selected devices have an asterisk (*) next to them. After making your changes to this menu, select Save Settings to NVRAM and then Exit.

VGA Consoles
Any device in the output device menu that has a Pci section in its path, but does not have a Uart section, is a VGA device. If you require a VGA console, select this device, and unmark all others
