Planning your CP server setup

Follow the planning instructions to set up CP server for server-based I/O fencing.

To plan your CP server setup

  1. Decide whether you want to host the CP server on a single-node VCS cluster, or on an SFHA cluster.

    Symantec recommends hosting the CP server on an SFHA cluster to make the CP server highly available.

  2. If you host the CP server on an SFHA cluster, review the following information. Make sure you make the decisions and meet these prerequisites when you set up the CP server:

    • You must set up shared storage for the CP server database during your CP server setup.

    • Decide whether you want to configure server-based fencing for the SFCFSHA cluster (application cluster) with a single CP server as coordination point or with at least three coordination points.

      Symantec recommends using at least three coordination points.

  3. Decide whether you want to configure the CP server cluster for IPM-based communication or HTTPS communication or both.

    For IPM-based communication, the CP server on release 6.1 and later supports clients prior to 6.1 release. When you configure the CP server, you are required to provide VIPs for IPM-based clients.

    For HTTPS-based communication, the CP server on release 6.1 and later only supports clients on release 6.1 and later.

  4. Decide whether you want to configure the CP server cluster in secure mode for IPM-based communication.

    Symantec recommends configuring the CP server cluster in secure mode for IPM-based secure communication between the CP server and its clients (SFCFSHA clusters). Note that you use IPM-based communication if you want the CP server to support clients that are installed with a release version prior to 6.1 release.

  5. Set up the hardware and network for your CP server.

    See CP server requirements.

  6. Have the following information handy for CP server configuration:

    • Name for the CP server

      The CP server name should not contain any special characters. CP server name can include alphanumeric characters, underscore, and hyphen.

    • Port number for the CP server

      Allocate a TCP/IP port for use by the CP server.

      Valid port range is between 49152 and 65535. The default port number for HTTPS-based communication is 443 and for IPM-based secure communication is 14250.

    • Virtual IP address, network interface, netmask, and networkhosts for the CP server

      You can configure multiple virtual IP addresses for the CP server.
