RHEL Version 4:

Look in the /var/log/httpd/error_log log file for service errors. You might see an
error similar to this:

Init: Unable to read server certificate from file /var/log/httpd/error_log

To create a self-signed certificate, see

Section 5.2 (page 55)

23.4 Troubleshooting CMF problems

The following table describes possible causes of problems with the Console Management Facility
(

CMF

) and provides actions to correct them.

Corrective actions

Cause/Symptom

Perform the following actions:

Verify that the cmfd daemon is running on the CMS:

# /etc/init.d/cmfd status

Restart it as follows if it is stopped:

# /etc/init.d/cmfd restart

Examine the /opt/hptc/cmf/logs/cmfd.log for
errors.

Verify cmfd -h for the usage and default startup
parameters.

The CMF is not running

Perform the appropriate actions:

Verify the BIOS configuration.

Verify that the management processor user name and
password have not been changed.

Verify the management processor's IP address.

The CMF retries failed connections periodically

Perform the appropriate actions:

Run the following command to check the connection
status:

# cmfmgr -s `headnode` console

Send a test message to /dev/console on the
managed system, then examine the log for that
message.

# pdsh -w server 'echo "Hello, world" >
/dev/console'
# ls -l
/hptc_cluster/adm/logs/cmf.dated/current/

Faulty or no connection

Determine if another connection to the VSP exists.

Stop the cmfd daemon, then use the ssh or telnet
command to connect to the management processor.

After logging in, enter vsp to access the VSP. If a
Console is not accessible error

message

occurs, it might be that someone else already has a
console connection.

Ensure that you can log into the management processor
to verify the IP address, the user name, and the
password are correct. Use either the telnet or ssh
command with the IP address of the management
processor as its argument.

In an extreme case, power off the managed system to
reset the management processor.

Connection is blocked

The management processor allows only one connection
at a time to the virtual serial port (VSP)

This is not related to the CMF.

Function keys do not work with some terminal
emulators
