Upgrade Guidelines

Follow these guidelines to upgrade from Sun Cluster 3.0 to Sun Cluster 3.1 software:

• Have available the test IP addresses your public network adapters will use. The scinstall upgrade utility will prompt you for a test IP address for each public network adapter in the cluster. See the IP Network Multipathing Administration Guide (Solaris 8) or System Administration Guide: IP Services (Solaris 9) for information about test IP addresses.

• You must upgrade all software to a version that is supported by Sun Cluster 3.1 software. For example, you must upgrade a data service agent that is supported on Sun Cluster 3.0 software to the version supported on Sun Cluster 3.1 software. If the related application is not also supported on Sun Cluster 3.1 software, you must also upgrade the application to a supported release.

• The scinstall upgrade utility only upgrades those data services that are provided with Sun Cluster 3.1 software. You must manually upgrade any custom or third-party data services.

• Upgrade from Solaris 8 to Solaris 9 software is not supported in a Sun Cluster configuration.

• Sun Cluster 3.1 software does not support direct upgrade from Sun Cluster 2.x software.

• Sun Cluster 3.1 software does not support downgrade back to Sun Cluster 3.0 software.
