Problem: Main server unreachable from RHEL client station

Purpose

Perform this procedure to check the IP connectivity between an NFM-P client and main server using ping commands. When the ping commands indicate that IP communication is active but there are still IP reachability issues, the problem could be poor LAN performance.

Steps
 
1 

Perform a ping test to measure reachability, as described in Problem: Lost connectivity to one or more network management domain stations.

2 

If you cannot ping the main server from a RHEL single-user client or client delegate server station, ensure that the server hostname is in the /etc/hosts file on the client station.

  1. Log on to the client station as the root user.

  2. Enter the following:

    # cd /etc ↵

  3. Open the hosts file with a plain-text editor such as vi.

  4. Edit the file, as required, to contain the following:

    server_IP server_hostname

    where

    server_IP is the IP address of the main server

    server_hostname is the hostname of the main server

  5. Save the changes and close the file.
