The following conditions must be met to upgrade from Sun Cluster 2.2 to Sun Cluster 3.0 12/01 software.
The cluster must have exactly two nodes and be a supported configuration for Sun Cluster 3.0 12/01 software. The upgrade does not support clusters of three or more nodes.
Only Ethernet adapters are supported. Transport adapters must have a transmission rate of 100 Mbit/sec or greater.
All cluster hardware must be stable and working properly.
All third-party applications must be functioning properly.
The cluster must already run on, or be upgraded to, at least the minimum required level of the Solaris 8 operating environment that supports Sun Cluster 3.0 12/01 software.
You must upgrade all Sun Cluster software, framework, and data services at the same time.
Sun Cluster 3.0 12/01 software does not support upgrading directly to Sun Cluster 3.0 12/01 software from Solstice HA 1.3, Sun Cluster 2.0, or Sun Cluster 2.1 software.
Sun Cluster 3.0 12/01 software does not support converting from one volume manager product to another during upgrade.
The upgrade from Sun Cluster 2.2 to Sun Cluster 3.0 12/01 software cannot be reversed after the scinstall(1M) command has been started on a node, even if the command does not complete successfully. To restart a failed upgrade, you must first reinstall Sun Cluster 2.2 software on the node.
