Observe the following requirements and restrictions when you upgrade to Sun Cluster 3.1 10/03 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 10/03 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 10/03 software. For example, you must upgrade a data service that is supported on Sun Cluster 3.0 software but is not supported on Sun Cluster 3.1 10/03 software to the version of that data service that is supported on Sun Cluster 3.1 10/03 software. If the related application is not supported on Sun Cluster 3.1 10/03 software, you must also upgrade that application to a supported release.
The scinstall upgrade utility only upgrades those data services that are provided with Sun Cluster 3.1 10/03 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 10/03 software supports only nonrolling upgrade from Solaris 8 software to Solaris 9 software.
Sun Cluster 3.1 10/03 software supports direct upgrade only from Sun Cluster 3.x software.
Sun Cluster 3.1 10/03 software does not support any downgrade of Sun Cluster software.
