10.1 Starting and Stopping Novell Cluster Services

Novell Cluster Services automatically starts after it is installed. It also automatically starts when you reboot your OES server.

If you need to restart adminfs, you must stop Novell Cluster Services before you stop adminfs, or you can reboot the server.

IMPORTANT:If you are using iSCSI for shared disk system access, ensure that you have configured iSCSI initiators and targets to start prior to starting Novell Cluster Services. You can do this by entering the following at the Linux terminal console:

chkconfig open-iscsi on

10.1.1 Starting Novell Cluster Services

If you stop Novell Cluster Services, you can restart it by doing the following:

  1. Open a terminal console, then log in as the root user.

  2. Use one of the following methods to start Novell Cluster Services:

    • At the command prompt, go to the /etc/init.d directory and enter

      ./novell-ncs start
      
    • At the command prompt, enter

      rcnovell-ncs start
      
  3. Verify the cluster status:

    cluster status
    

10.1.2 Stopping Novell Cluster Services

Novell Cluster Services is a kernel-space application. As with any kernel-space application, unloading it is a best effort and is not guaranteed to stop the modules. If Novell Cluster Services is busy providing services from the kernel when you attempt to stop it, the process might not stop, and a reboot might be required.

  1. Open a terminal console, then log in as the root user.

  2. Check whether the node is active in the cluster. Enter

    cluster view
    

    If the node is in the cluster (and not still in a process of joining the cluster), it is relatively safe to attempt to stop it.

  3. Use one of the following methods to stop Novell Cluster Services:

    • Go to the /etc/init.d directory and enter

      ./novell-ncs stop
      
    • At the command prompt, enter

      rcnovell-ncs stop
      
  4. Verify the cluster status:

    cluster status
    
  5. If you get in a state where the node has not joined the cluster and Novell Cluster Services cannot be stopped:

    1. Disable autostart on reboot. Enter

      chkconfig novell-ncs off
      
    2. Reboot the server.

    3. Start Novell Cluster Services manually. Enter

      rcnovell-ncs start
      
    4. Diagnose why the node had trouble joining the cluster.

    5. (Optional) Re-enable autostart for the node. Enter

      chkconfig novell-ncs on
      

10.1.3 Enabling and Disabling the Automatic Start of Novell Cluster Services

Novell Cluster Services automatically starts by default after it is installed and on server reboot.

To cause Novell Cluster Services to not start automatically after a server reboot:

  1. Open a terminal console, then log in as the root user.

  2. Enter the following at a Linux terminal console:

    chkconfig novell-ncs off
    
  3. Reboot the server.

  4. After rebooting, you must manually start Novell Cluster Services by entering

    rcnovell-ncs start
    

To cause Novell Cluster Services to resume starting automatically after a server reboot:

  1. Open a terminal console, then log in as the root user.

  2. Enter the following at a Linux terminal console:

    chkconfig novell-ncs on 
    
  3. Reboot the server.
