How to Prepare the Cluster for Update (Standard Update)

Perform this procedure to remove the cluster from production before you perform a standard update. Performing a standard update also updates the Oracle Solaris OS to the latest compatible version. Perform all steps from the global zone only.

Before You Begin

Perform the following tasks:

  • Ensure that the configuration meets the requirements for update. See Overview of Updating Oracle Solaris Cluster Software.

  • Have available the installation media, documentation, and software updates for all software products that you are updating, including the following software:

    • Oracle Solaris OS

    • Oracle Solaris Cluster

    • Applications that are managed by Oracle Solaris Cluster data services

    • Any other third-party applications to update

    For instructions on updating single or multiple packages, see Updating Software Packages.

  • If you use role-based access control (RBAC) instead of the root role to access the cluster nodes, ensure that you can become an administrator with rights for all Oracle Solaris Cluster commands. This series of update procedures requires the following Oracle Solaris Cluster RBAC authorizations if the user is not the root role:

    • solaris.cluster.modify

    • solaris.cluster.admin

    • solaris.cluster.read

    See User Rights Management in Securing Users and Processes in Oracle Solaris 11.4 for more information about using RBAC roles. See the Oracle Solaris Cluster man pages for the RBAC authorization that each Oracle Solaris Cluster subcommand requires.

  1. Ensure that the cluster is functioning normally.
    1. View the current status of the cluster by running the following command from any node.
      phys-schost% cluster status

      See the cluster(8CL) man page for more information.

    2. Search the /var/adm/messages log on the same node for unresolved error messages or warning messages.
    3. Check the volume-manager status.
  2. Assume the root role on a node of the cluster.
  3. Ensure that all shared data is backed up.
  4. Ensure that each system disk is backed up.
