Sun Cluster Geographic Edition Installation Guide

ProcedureHow to Prepare the Cluster for Patch Installation

  1. Ensure that the cluster is functioning properly.

    To view the current status of the cluster, run the following command from any node:


    % scstat
    

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

    Search the /var/adm/messages log on the same node for unresolved error messages or warning messages.

    Check the volume manager status.

  2. On a node of the cluster, become root.


    % su
    
  3. Remove all application resource groups from protection groups.

    Highly available applications do not have downtime during the Sun Cluster Geographic Edition software patch installation.


    # geopg remove-resource-group resourcegroup protectiongroupname
    

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

  4. Perform the preceding steps on all clusters that have a partnership with this cluster.

  5. Stop all protection groups that are active on the cluster.


    # geopg stop protectiongroupname -e local | global
    

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

  6. Stop the Sun Cluster Geographic Edition infrastructure.


    # geoadm stop
    

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

  7. Stop the common agent container.


    # /opt/SUNWcacao/bin/cacaoadm stop
    

    Note –

    You must use common agent container 1.1, which is located in /opt/SUNWcacao/bin. Use the /opt/SUNWcacao/bin/cacaoadm -V command to check which version of common agent container you are using.
