4.3 Upgrading Cluster-Enabled FTP Server

Use the following sections to know more about upgrading cluster-enabled FTP server:

4.3.1 Active/Passive Cluster Mode

  1. After the upgrade from NetWare 6 Support Pack 3/NetWare 5.1 Support Pack 6 is complete, execute unload nwftpd to stop FTP services running on all the nodes that you are cluster-enabling.

  2. Edit autoexec.ncf and comment out or remove the nwftpd entry from every FTP server in each node in the cluster.

    This lets FTP Server be started by Novell Cluster Services.

  3. Bring the resource offline.

  4. Bring the resource status to offline and then modify the load and unload scripts:

    1. Using ConsoleOne®, select and right-click the Cluster resource object, then click Properties > Scripts > Cluster Resource Load Script and Cluster Resource Unload Script.

    2. Add the following at the end of the existing load script:

      load nwftpd -c shared_vol_name:\etc\ftpserv.cfg 

      load ftpstat

      The load script specifies the commands to start the resource or service on a server or to mount the volume on a server.

    3. Add the following at the beginning of the unload script:

      unload ftpstat

      unload nwftpd

      The unload script specifies how the application or resource should terminate.

4.3.2 Active/Active Cluster Mode

Prerequisites:

  • Ensure that every node in the cluster has the same configuration and restrictions file

  • Make sure to use the default load/unload scripts

  1. After the upgrade from NetWare 6 Support Pack 3 / NetWare 5.1 Support Pack 6 is complete, execute unload nwftpd to stop FTP services running on all the nodes that you are cluster enabling.

  2. Edit autoexec.ncf, and if it is commented, uncomment the nwftpd entry from every FTP server in each node in the cluster.

    This lets FTP Server be started by Novell Cluster Services.

  3. Bring the resource offline.
