Sun Cluster 3.1 10/03 Software Installation Guide

How to Prepare the Cluster for Upgrade (Rolling)

Perform this procedure on one node at a time. The upgraded node is taken out of the cluster, while the remaining nodes continue to function as active cluster members.

Note –

Do not use any new features of the update release, install new data services, or issue any administrative configuration commands until all nodes of the cluster are successfully upgraded.

  1. Ensure that the configuration meets requirements for upgrade.

    See Upgrade Requirements and Restrictions.

  2. Have available the CD-ROMs, documentation, and patches for all the software products you are upgrading before you begin to upgrade the cluster.

    • Solaris 8 or Solaris 9 operating environment

    • Sun Cluster 3.1 10/03 framework

    • Sun Cluster 3.1 10/03 data services (agents)

    • Applications that are managed by Sun Cluster 3.1 10/03 data-service agents

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

  3. (Optional) Install Sun Cluster 3.1 10/03 documentation.

    Install the documentation packages on your preferred location, such as an administrative console or a documentation server. See the index.html file at the top level of the Sun Cluster 3.1 10/03 CD-ROM to access installation instructions.

  4. From any node, view the current status of the cluster.

    Save the output as a baseline for later comparison.


    % scstat
% scrgadm -pv[v]

    See the scstat(1M) and scrgadm(1M) man pages for more information.

  5. Become superuser on one node of the cluster to upgrade.

  6. Move all resource groups and device groups that are running on the node to upgrade.


    # scswitch -S -h from-node
    -S

    Moves all resource groups and device groups

    -h from-node

    Specifies the name of the node from which to move resource groups and device groups

    See the scswitch(1M) man page for more information.

  7. Verify that the evacuation completed successfully.


    # scstat -g -D
    -g

    Show status for all resource groups

    -D

    Show status for all disk device groups

  8. Ensure that the system disk and data is backed up.

  9. Shut down the node to upgrade and boot it into noncluster mode.


    # shutdown -y -g0
ok boot -x

    The other nodes of the cluster continue to function as active cluster members.

  10. Do you intend to upgrade the Solaris software to a Maintenance Update release?

    Note –

    The cluster must already run on, or be upgraded to, at least the minimum required level of the Solaris operating environment to support Sun Cluster 3.1 10/03 software. See the Sun Cluster 3.1 10/03 Release Notes for information about supported releases of the Solaris operating environment.
