Perform this procedure on all clusters that have a partnership with the cluster you are upgrading to remove the Sun Cluster Geographic Edition layer from production. On the Solaris 10 OS, perform all steps from the global zone only.
Perform the following tasks:
Ensure that the configuration meets the requirements for the upgrade. See Upgrade Requirements and Software Support Guidelines.
Have available the installation media, documentation, and patches for all software products that you are upgrading, including Solaris OS, Sun Cluster software, and Sun Cluster Geographic Edition 3.2 2/08 software.
Ensure that you have installed all the required patches for your cluster configuration on each node of every cluster before you start upgrading the software. See Required Patches in Sun Cluster Geographic Edition 3.2 2/08 Release Notes for the location of patches and installation instructions.
If you want to upgrade the Solaris OS or other applications during the Sun Cluster Geographic Edition software upgrade process, you must remove the Sun Cluster Geographic Edition packages before you upgrade the Solaris OS or other applications. For information about uninstalling Sun Cluster Geographic Edition software, see Uninstalling Sun Cluster Geographic Edition 3.2 Software to determine the proper method of uninstallation.
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.
Become superuser on a node of the cluster.
Remove all application resource groups from protection groups.
Highly available applications do not have downtime during the Sun Cluster Geographic Edition software upgrade.
# geopg remove-resource-group resourcegroup protectiongroup |
See the geopg(1M) man page for more information.
Perform the preceding steps on all clusters that have a partnership with this cluster.
Stop all protection groups that are active on the cluster.
# geopg stop protectiongroup -e local |
See the geopg(1M) man page for more information.
Stop the Sun Cluster Geographic Edition infrastructure.
# geoadm stop |
See the geoadm(1M) man page for more information.
