Upgrade Requirements and Software Support Guidelines
How to Prepare the Cluster for an Upgrade
This section provides the following information to upgrade a Geographic Edition configuration:
Observe the following requirements and software-support guidelines on all clusters that have a partnership with the cluster that you are upgrading when you upgrade a cluster:
Supported hardware - The cluster hardware must be a supported configuration for Geographic Edition 4.0 software. Contact your Oracle representative for information about Geographic Edition configurations that are currently supported.
Minimum Oracle Solaris OS version - The cluster must run on Oracle Solaris 11 software, including the most current required software updates.
Minimum Oracle Solaris Cluster version - The cluster must run on Oracle Solaris Cluster 4.0 software.
Cluster partnerships - For all clusters that have a partnership with the cluster that you are upgrading, all nodes of a cluster must run either Geographic Edition 3.3 5/11 or 4.0 software.
Perform this procedure on all clusters that have a partnership with the cluster you are upgrading to remove the Geographic Edition layer from production. Perform all steps from the global zone only.
Before You Begin
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 or the IPS publisher configured, documentation, and software updates for all software products that you are upgrading, including Oracle Solaris OS, Oracle Solaris Cluster software, and Geographic Edition 4.0 software.
Ensure that you have installed all the required software updates for your cluster configuration on each node of every cluster before you start upgrading the software. See Software Updates in Oracle Solaris Cluster 4.0 Release Notes for the location of software updates and installation instructions.
% cluster status
See the cluster(1CL) man page for more information.
Highly available applications do not have downtime during the Geographic Edition software upgrade.
# geopg remove-resource-group resourcegroup protectiongroup
See the geopg(1M) man page for more information.
# geopg stop protectiongroup -e local
See the geopg(1M) man page for more information.
# geoadm stop
See the geoadm(1M) man page for more information.
Next Steps
Upgrade the Geographic Edition software on the clusters. Go to How to Upgrade Geographic Edition Software.
Perform this procedure on all nodes of the cluster. You can perform this procedure on more than one node at the same time.
![]() | Caution - If the cluster is in a partnership, both partners must be installed with Geographic Edition 3.3 5/11 or 4.0 software before the Geographic Edition 4.0 software can start. |
Before You Begin
Ensure that the cluster is prepared for upgrade. See How to Prepare the Cluster for an Upgrade.
% cluster status
See the cluster(1CL) man page for more information.
# pkg update ha-cluster-geo-incorporation
Ensure that Geographic Edition software upgrade is completed on all cluster nodes before you continue to the next step.
# geoadm start
localnode# geops remove-trust -c remotecluster
remotenode# geops remove-trust -c localcluster
localnode# geops add-trust -c remotecluster
remotenode# geops add-trust -c localcluster
# geops verify-trust -c partnercluster
For a complete example of how to configure and join a partnership, see How to Join a Partnership in Oracle Solaris Cluster Geographic Edition System Administration Guide.
# geopg add-resource-group resourcegroup protectiongroup
See the geopg(1M) man page for more information.
# geopg start protectiongroup -e local [-n]
See the geopg(1M) man page for more information.
Next Steps
Go to How to Verify Upgrade of Geographic Edition Software.
Perform this procedure to verify that the cluster is successfully upgraded to Geographic Edition 4.0 software. Perform all steps from the global zone only.
Before You Begin
Ensure that all upgrade procedures are completed for all cluster nodes that you are upgrading.
# geoadm -V
The last line of output states which version of Geographic Edition software the node is running. This version should match the version to which you just upgraded.
Note - The version number that the geoadm -v command returns does not coincide with the marketing release version numbers. The version number for Geographic Edition 4.0 software is 4.0.
# geoadm status
# geopg switchover remotecluster protectiongroup
You must test your geographically separated cluster properly, so that no problems prevent a switchover. Upgrading the secondary cluster first and switching over to it enables you to verify that switchover still works. If the switchover fails, the primary site is untouched and you can switch back. If switchover works on the secondary site, then after a certain 'soak time' you can upgrade the primary site as well.
Note - A switchover might interrupt the services that are running on the cluster. You should carefully plan the required tasks and resources before you perform a switchover.
If you have added your application resource groups back into the protection groups, performing a switchover shuts down the applications on the original primary cluster and migrates the applications to the secondary cluster.
