Installation Overview

Language:

You can install Geographic Edition software on a running cluster without disruption. Because the Geographic Edition software installation process does not require you to restart Oracle Solaris Cluster software, the cluster remains in production with services running.

Note - Ensure that you have installed all the required software updates for your cluster configuration on each node of every cluster before you start installing the Geographic Edition software. See Chapter 11, Updating Your Software in Oracle Solaris Cluster 4.3 System Administration Guide for installation instructions.

For zone clusters that are already created, when you install the Geographic Edition software, the software is propagated to the zone-cluster nodes by default. If you create a zone cluster after Geographic Edition software is installed in the global cluster, you must install the Geographic Edition software in the new zone-cluster nodes.

This section contains lists of the tasks you need to perform to create a Geographic Edition configuration.

Prerequisite Configuration Tasks

Before you begin administering the Geographic Edition framework, you must identify the Oracle Solaris Cluster installations you want to host protection groups. Then, you need to adjust the Oracle Solaris Cluster configuration and environment to support the formation of partnerships and protection groups with the Geographic Edition framework. The following table describes these prerequisite tasks.

Table 4 Prerequisite Configuration Tasks

Task	Description
1. Set the cluster name to the name you want to use with the Geographic Edition framework.	Use the `cluster` command. For more information about this requirement, see How to Enable the Geographic Edition Framework.
2. Set up the IP address and host maps for the cluster that is enabled to run Geographic Edition framework.	See Chapter 2, Installing Software on Global-Cluster Nodes in Oracle Solaris Cluster 4.3 Software Installation Guide.
3. Install and configure your data replication product. Note - This step is required before you can create protection groups with the `geopg create` command.	See the Geographic Edition data replication guide for the product you are using. A list of available manuals is provided in Protection Groups.
4. Port and configure application configuration and corresponding resource groups on clusters that are candidates for partnership.	See the guidelines and prerequisites in Creating a Partnership.

Installation and Configuration Tasks

After you have completed the prerequisite configuration tasks, you can install and configure the Geographic Edition software as described in the following table.

Table 5 Geographic Edition Installation and Configuration Tasks

Task	Description and Documentation
1. Install Geographic Edition software.	See Installing the Geographic Edition Software.
2. Set up security between the candidate partner clusters.	Exchange certificates, as described in Security Certificates. (Optional) Configure a secure logical hostname that uses IP Security Architecture (IPsec), as described in IP Security (IPsec).
3. If using a zone cluster as a partner, prepare the zone cluster for membership.	See Preparing a Zone Cluster for Partner Membership.
4. Enable the Geographic Edition framework.	Issue the `geoadm start` command. For more information, see Enabling the Geographic Edition Framework.
5. Create partnerships.	See Configuring a Partnership.
6. Configure data replication.	See the Geographic Edition data replication manual for the product you use. A list of available manuals is provided in Protection Groups.
7. Create and validate protection groups.	See the Geographic Edition manual for the data replication product you use. To create a protection group that does not require data replication, see Creating a Protection Group That Does Not Require Data Replication.
8. Add data replication device groups and application resource groups to the protection group.	See the Geographic Edition manual for the data replication product you use.
9. Bring online (activate) the protection groups.	See How to Activate a Protection Group.
10 (Optional) Create sites and multigroups.	Set up sets of clusters and protection groups on which to perform switchover or takeover in a single operation. For more information, see Configuring Sites and Multigroups.
11. Test the configured partnership and protection groups to validate the setup.	Perform a trial switchover or takeover and test some simple failure scenarios. See Chapter 10, Migrating Services in Oracle Solaris Cluster 4.3 Geographic Edition System Administration Guide and procedures to migrate services in the Geographic Edition manual for your data replication product. Note - You cannot perform personality swaps if you are running EMC Symmetrix Remote Data Facility/Asynchronous data replication.
