Dell R610 + RHEL 5.4 - Console freeze to black


Hi,

We have a Dell PE R610 installed with RHEL 5.4 in our environment and we have found a strange issue with it. The server's iDRAC (java virtual) console displays the boot up messages when the server boots up and once the login prompt is reached, the console window just becomes blank and nothing can be seen. No Key strokes brings the console screen alive.

However, the server is up and running and reachable through SSH. Performed the below tasks to resolve the issue, but no luck!
  1. Replaced the iDRAC card
  2. Modifed the Baud Rate settings in the JV console configuration
  3. Enabled the "pass keystroke" in the console options.
  4. Re-installed JRE plugin in desktop
  5. Connected a keyboard directly to the server and passed keystrokes

I was wondering if there would be some settings in Redhat related to TTY to go to sleep after a few seconds of idle time?

Request some knowledge sharing on this, if someone had already noticed this issue before.

Thanks in advance!

Sridhar

The biggest thing that I have seen with Dell systems (or any system for that matter) is make sure that you have the latest firmware installed on the system. Also make sure to turn off c-states in bios as that has caused problems in the past as well. That is where I would start.

Hi Grim,

Our server is running with the latest recommended firmware versions recommended by Dell. Could you please help me understand how to turn off the "C-State" in the BIOS?.

They are under the power options in the BIOS. I don't recall exactly where. I just recall a Dell tech asking us to turn those options off.
