Migrating to Continentalclusters A.08.00

Continentalclusters version A.08.00 includes enhanced features and capabilities, such as support for modular packages, IPv6 support, and a secure communication protocol for inter-cluster operations. HP recommends that you migrate Continentalclusters to the latest version to obtain the benefits of these features. Upgrading to Continentalclusters A.08.00 requires re-applying the Continentalclusters configuration.

IMPORTANT: Only configurations using Continentalclusters software version A.06.00 or higher can be upgraded to Continentalclusters software version A.08.00. For configurations using versions earlier than A.06.00 must necessarily upgrade to version A.08.00 before migrating to Continentalclusters version A.08.00.

Complete the following steps to migrate to Continentalclusters A.08.00:

1.Set up the secure communication environment.

For more information on setting up the SSH environment for Continentalclusters, see “Setting up Security with Continentalclusters Version A.08.00” (page 60).

2.Halt the monitor package.

#cmhaltpkg ccmonpkg

3.Install Continentalclusters A.08.00 using the swinstall command on all nodes of the cluster.

4.Verify the Continentalclusters configuration (text file) file that was used to create this Continentalclusters configuration.

#cmcheckconcl -v -C cmconcl.config

5.Apply the same Continentalclusters configuration file used in the previous step.

#cmapplyconcl -v -C cmconcl.config

6.Start the monitor package.

#cmrunpkg ccmonpkg

7.Verify the configuration and the status of the cluster.

#cmviewconcl

Testing the Continentalclusters

This section presents some test procedures and scenarios. Some scenarios presume certain configurations that may not apply to all environments. Additionally, these tests do not eliminate the need to perform standard Serviceguard testing for each cluster individually.

CAUTION: Data and system corruption can occur as a result of testing. System and data backups should always be done prior to testing.

Testing Individual Packages

Use procedures like the following to test individual packages:

1.Use the cmhaltpkg command to shut down the package on the primary cluster that corresponds to the package to be tested on the recovery cluster.

2.Do not switch any users to the recovery cluster. The application must be inaccessible to users during this test.

3.Start up the package to be tested on the recovery cluster using the cmrunpkg command.

4.Access the application manually using a mechanism that tests network connectivity.

5.Perform read-only actions to verify that the application is running appropriately.

6.Shut down the application on the recovery cluster using the cmhaltpkg command.
