Upgrade Requirements and Support Guidelines

Observe the following requirements and support guidelines when you upgrade to Sun Cluster 3.1 9/04 software:

• The cluster must run on or be upgraded to at least Solaris 8 2/02 software, including the most current required patches.

• The cluster hardware must be a supported configuration for Sun Cluster 3.1 9/04 software. Contact your Sun representative for information about current supported Sun Cluster configurations.

• You must upgrade all software to a version that is supported by Sun Cluster 3.1 9/04 software. For example, if a data service is supported on Sun Cluster 3.0 software but is not supported on Sun Cluster 3.1 9/04 software, you must upgrade that data service to the version of that data service that is supported on Sun Cluster 3.1 9/04 software. See “Supported Products” in Sun Cluster 3.1 9/04 Release Notes for Solaris OS for support information about specific data services.

• If the related application of a data service is not supported on Sun Cluster 3.1 9/04 software, you must upgrade that application to a supported release.

• The scinstall upgrade utility only upgrades those data services that are provided with Sun Cluster 3.1 9/04 software. You must manually upgrade any custom or third-party data services.

• For upgrade from a Sun Cluster 3.0 release, have available the test IP addresses to use with your public-network adapters when NAFO groups are converted to Internet Protocol (IP) Network Multipathing groups. The scinstall upgrade utility prompts you for a test IP address for each public-network adapter in the cluster. A test IP address must be on the same subnet as the primary IP address for the adapter.

  See the IP Network Multipathing Administration Guide (Solaris 8) or System Administration Guide: IP Services (Solaris 9) for information about test IP addresses for IP Network Multipathing groups.

• Sun Cluster 3.1 9/04 software supports only nonrolling upgrade from Solaris 8 software to Solaris 9 software.

• Sun Cluster 3.1 9/04 software supports direct upgrade only from Sun Cluster 3.x software.

• Sun Cluster 3.1 9/04 software does not support any downgrade of Sun Cluster software.

• Sun Cluster 3.1 9/04 software does not support upgrade between architectures.

• Sun Cluster 3.1 9/04 software does not support the Live Upgrade method to upgrade Solaris software in a Sun Cluster configuration.
