Sun Cluster Software Installation Guide for Solaris OS

How to Prepare for Cluster Software Installation

Before you begin to install software, make the following preparations.

  1. Read the following manuals for information that can help you plan your cluster configuration and prepare your installation strategy.

  2. Have available all related documentation, including third-party documents.

    The following is a partial list of products whose documentation you might need to reference during cluster installation:

    • Solaris OS

    • Solstice DiskSuite or Solaris Volume Manager software

    • Sun StorEdge QFS software

    • SPARC: VERITAS Volume Manager

    • SPARC: Sun Management Center

    • Third-party applications

  3. Plan your cluster configuration.

    Caution – Caution –

    Plan your cluster installation completely. Identify requirements for all data services and third-party products before you begin Solaris and Sun Cluster software installation. Failure to do so might result in installation errors that require that you completely reinstall the Solaris and Sun Cluster software.

    For example, the Oracle Real Application Clusters Guard option of Oracle Real Application Clusters has special requirements for the hostnames that you use in the cluster. Another example with special requirements is Sun Cluster HA for SAP. You must accommodate these requirements before you install Sun Cluster software because you cannot change hostnames after you install Sun Cluster software.

    Also note that both Oracle Real Application Clusters and Sun Cluster HA for SAP are not supported for use in x86 based clusters.

  4. Get all necessary patches for your cluster configuration.

    See “Patches and Required Firmware Levels” in Sun Cluster 3.1 Release Notes for the location of patches and installation instructions.

    1. Copy the patches that are required for Sun Cluster into a single directory.

      The directory must be on a file system that is accessible by all nodes. The default patch directory is /var/cluster/patches/.

      Tip –

      After you install Solaris software on a node, you can view the /etc/release file to see the exact version of Solaris software that is installed.

    2. (Optional) If you are not using SunPlex Installer, you can create a patch list file.

      If you specify a patch list file, SunPlex Installer only installs the patches that are listed in the patch list file. For information about creating a patch-list file, refer to the patchadd(1M) man page.

    3. Record the path to the patch directory.

  5. (Optional) Use Cluster Control Panel software to connect from an administrative console to your cluster nodes.

    Go to How to Install Cluster Control Panel Software on an Administrative Console.

  6. Choose the Solaris installation procedure to use.
