Use this procedure to troubleshoot problems entering command or
receiving double prompts within a Serial over LAN session.
Problem
Within a Serial over LAN session,
you have trouble entering commands or you are receiving double prompts.
Investigation
Perform these steps to resolve the
problem:
- Check the Return key settings for the keyboard in your terminal program.
Make sure that only a line feed character is sent whenever the Return key
is pressed.
- This is the default for Telnet sessions.
- The terminal application PuTTY has a configuration setting for the Return
key. From the Configuration menu, click Connection →Telnet.
- The service processor on older blade servers might block SOL output to
a blade server running Linux. If this occurs, type Ctrl-q in
the Serial over LAN session
to clear the keystroke buffer.
- Verify that the operating system running on the blade server supports Serial over LAN. For more information
see the IBM BladeCenter Serial over LAN Setup Guide.
- Make sure that the operating system running on the blade server has been
set up correctly for Serial over LAN console
access. For more information see the IBM BladeCenter Serial over LAN
Setup Guide.
