Sun Cluster Software Installation Guide for Solaris OS

How to Configure Sun Cluster Software on All Nodes (scinstall)

Perform this procedure to configure Sun Cluster software on all nodes of the cluster.

  1. Ensure that the Solaris operating environment is installed to support Sun Cluster software.

    If Solaris software is already installed on the node, you must ensure that the Solaris installation meets the requirements for Sun Cluster software and any other software that you intend to install on the cluster. See How to Install Solaris Software for more information about installing Solaris software to meet Sun Cluster software requirements.

  2. Did you disable remote configuration during Sun Cluster software installation?

    • If no, proceed to Step 3.

    • If yes, enable remote shell (rsh(1M)) or secure shell (ssh(1)) access for superuser to all cluster nodes.

  3. Do you intend to use the scinstall utility to install patches?

    • If no, proceed to Step 4.

    • If yes, download patches to a patch directory.

      The scinstall command checks for patches in the /var/cluster/patches directory or the /var/patches directory. If neither of the directories exist, then no patches are added. If both directories exist, then only the patches in the /var/cluster/patches directory are added.

      You can include a patch-list file in the patch directory. The default patch-list file name is patchlist. For information about creating a patch-list file, refer to the patchadd(1M) man page.

  4. Complete one of the following configuration worksheets:

Then perform the procedures in How to Install Sun Cluster Software Packages and in this procedure to reinstall the software and configure the node with the correct information.

  5. Become superuser on the cluster node from which you intend to configure the cluster.

  6. Start the scinstall utility.


    # /usr/cluster/bin/scinstall

  7. Follow these guidelines to use the interactive scinstall utility:

    • Interactive scinstall enables you to type ahead. Therefore, do not press the Return key more than once if the next menu screen does not appear immediately.

    • Unless otherwise noted, you can press Control-D to return to either the start of a series of related questions or to the Main Menu.

    • Default answers or answers to previous sessions are displayed in brackets ([ ]) at the end of a question. Press Return to enter the response that is in brackets without typing it.

  8. From the Main Menu, choose Install a cluster or cluster node.


     *** Main Menu ***

    Please select from one of the following (*) options:

      * 1) Install a cluster or cluster node
        2) Configure a cluster to be JumpStarted from this install server
        3) Add support for new data services to this cluster node
      * 4) Print release information for this cluster node

      * ?) Help with menu options
      * q) Quit

    Option:  1

  9. From the Install Menu, choose Install all nodes of a new cluster.

  10. From the Type of Installation menu, choose either Typical or Custom.

  11. Follow the menu prompts to supply your answers to Table 2–2 or Table 2–3, which you completed in Step 4.

    The scinstall utility installs and configures all cluster nodes and reboots the cluster. The cluster is established when all nodes have successfully booted into the cluster. Sun Cluster installation output is logged in a /var/cluster/logs/install/scinstall.log.N file.
