Sun Cluster Geographic Edition System Administration Guide

Overview of Sun Cluster Geographic Edition Administration Tasks

This section provides a starting point for administering the Sun Cluster Geographic Edition software. This section contains the following tasks:

Prerequisite Administration Tasks

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

Table 2–2 Sun Cluster Geographic Edition Prerequisite Tasks

Task 

Description 

Set the SC-clustername to the cluster name you want to use with the Sun Cluster Geographic Edition software.

Use the cluster(1CL) command. For more information, see How to Enable Sun Cluster Geographic Edition Software.

Set up the IP address and host maps for the cluster that is enabled to run Sun Cluster Geographic Edition software. 

See Chapter 2, Installing Software on Global-Cluster Nodes, in Sun Cluster Software Installation Guide for Solaris OS.

Install and configure your data replication product. 

See the Sun StorageTek Availability Suite, Hitachi TrueCopy, or EMC Symmetrix Remote Data Facility documentation. 

This step is required before you can create protection groups with the geopg create command.

Port and configure application configuration and corresponding resource groups on clusters that are candidates for partnership. 

You can use the Sun Cluster scsnapshot tool to facilitate porting of application resource groups. See Creating and Modifying a Partnership for more information.

Enable the common agent container on all nodes of both clusters.  

See Enabling the Sun Cluster Geographic Edition Software.

Sun Cluster Geographic Edition Administration Tasks

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

Table 2–3 Sun Cluster Geographic Edition Administration Tasks

Task 

Description and Documentation 

Install Sun Cluster Geographic Edition software. 

See the Sun Cluster Geographic Edition Installation Guide.

Set up security between the candidate partner clusters. 

Enable the Sun Cluster Geographic Edition software. 

Use the geoadm start command.

For more information, see Enabling the Sun Cluster Geographic Edition Software.

Create partnerships. 

See How to Create a Partnership. This procedure includes the following:

Configure data replication. 

For information about replicating data by using Sun StorageTek Availability Suite, see Chapter 1, Replicating Data With Sun StorageTek Availability Suite Software, in Sun Cluster Geographic Edition Data Replication Guide for Sun StorageTek Availability Suite.

For information about replicating data by using Hitachi TrueCopy, see Chapter 1, Replicating Data With Hitachi TrueCopy Software, in Sun Cluster Geographic Edition Data Replication Guide for Hitachi TrueCopy.

For information about replicating data by using EMC Symmetrix Remote Data Facility, see Chapter 1, Replicating Data With EMC Symmetrix Remote Data Facility Software, in Sun Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility.

Create protection groups. 

Bring the protection groups online. 

See one of the following data replication guides: 

Test the configured partnership and protection groups to validate the setup.  

Perform a trial switchover or takeover and test some simple failure scenarios. See one of the following data replication guides:  

Note –

You cannot perform personality swaps if you are running EMC Symmetrix Remote Data Facility/Asynchronous data replication.

Migrate services to the partner cluster. 

See one of the following data replication guides:  

Note –

You cannot perform personality swaps if you are running EMC Symmetrix Remote Data Facility/Asynchronous data replication.

Take over services from primary to secondary during a disaster. 

See one of the following data replication guides:  

Recover from a takeover. 

Take a protection group offline.

Delete a protection group. 

See How to Delete a Sun StorageTek Availability Suite Protection Group in Sun Cluster Geographic Edition Data Replication Guide for Sun StorageTek Availability Suite, How to Delete a Hitachi TrueCopy Protection Group in Sun Cluster Geographic Edition Data Replication Guide for Hitachi TrueCopy, or How to Delete an EMC Symmetrix Remote Data Facility Protection Group in Sun Cluster Geographic Edition Data Replication Guide for EMC Symmetrix Remote Data Facility.

Delete a partnership. 

See Leaving or Deleting a Partnership.

Disable the Sun Cluster Geographic Edition software. 

See How to Disable the Sun Cluster Geographic Edition Software.

Uninstall the Sun Cluster Geographic Edition software. 

See the Sun Cluster Geographic Edition Installation Guide.
