CDE can't start on rx 4640

[Sakui]

I have itanium server rx 4640 with HP-ux 11i11.23 installed.I can't do a full installed from VGA card. I can only see a part of boot process on the VGA but can't see the rest of the installation. I have to use a secure web console to continue the installation.This is wht i see LCD screen "console is serial device no further output will appear on this output device. How do I clear that message from the screen.Because of this problem i can't see the boot process until X Server start with CDE desktop.When the LCD is connected i can't go into single user mode.because i will see nothing on the screen.
A few days ago, i restarted the server and repostion it. CDE desktop can nolonger start anymore. I connected with a web console to view the logs and restart the Xserver daemon.
How do i clear tht console message and start my Xserver properly with the CDE desktop.

Hi,

Do you not have a GSP to work from? That is where I tend to do my reboots from if there is a problem with the server...that way, I can watch it come back up line by line.
