Upgrade Overview

This section describes the procedures for upgrading to the latest release of Sun Cluster 2.2 from existing Solstice HA 1.3, Sun Cluster 2.0, Sun Cluster 2.1, and Sun Cluster 2.2 configurations. The upgrade paths documented in this chapter preserve the existing cluster configuration and data. Your systems can remain online and available during most of the upgrade.

To upgrade from Solstice HA 1.3:

• Use the procedure "How to Upgrade to Sun Cluster 2.2 From HA 1.3".

• For configurations using Solstice DiskSuite only: if you will be upgrading to Solaris 7, you must upgrade to Solstice DiskSuite 4.2. If you will be upgrading to Solaris 8, you must upgrade to Solstice DiskSuite 4.2.1.

To upgrade from Sun Cluster 2.0 or 2.1:

• Use the planning information and procedures in "Upgrading to Sun Cluster 2.2 From Sun Cluster 2.0 or 2.1".

• If your volume manager is SSVM, you must upgrade to VERITAS Volume Manager, verstion 3.0.4 or later. See your service provider for the latest information about supported versions of the volume manager.

To upgrade to the latest version of Sun Cluster 2.2 on Solaris 8 from an earlier version of Sun Cluster 2.2 on Solaris 2.6 or 7:

• Use the planning information and procedures in "Upgrading to Sun Cluster 2.2 on Solaris 8 From Sun Cluster 2.2 on Solaris 2.6 or Solaris 7".

• If your volume manager is Solstice DiskSuite 4.2 and you will be upgrading to Solaris 8, you must upgrade to Solstice DiskSuite 4.2.1.

  Note -

  Sun Cluster 2.2 does not support conversion from Solstice DiskSuite to VERITAS Volume Manager.

If you also want to make configuration changes such as adding disks or services, first complete the upgrade and then make the configuration changes by following the procedures documented in the Sun Cluster 2.2 System Administration Guide.

Before starting your upgrade, make sure the versions of any applications you plan to run are compatible with the version of the Solaris operating environment you plan to run.

To upgrade Solaris software, you might need to increase the size of your root (/) and /usr partitions on the root disks of all Sun Cluster servers in the configuration, to accommodate the Solaris operating environment.

You must install the Entire Distribution Solaris software packages. See your Solaris advanced system administration documentation for details.

The behavior of DNS changes between Solaris 2.6 and Solaris 8. This is because the default bind version differs between these operating environments. This change requires an update to some DNS configuration files. See your DNS documentation for details and instructions.
