Verify that you have obtained and installed the appropriate licenses for your software. If you install your licenses incorrectly or incompletely, the nodes might fail to boot correctly.
Check with a Sun Enterprise Services representative for the current supported topologies for Sun Cluster Support for Oracle RAC, cluster interconnect, storage management scheme, and hardware configurations.
Ensure that you have installed all the applicable software patches for the Solaris Operating System, Sun Cluster, Oracle, and your volume manager. If you need to install any Sun Cluster Support for Oracle RAC patches, you must apply these patches after you install the data service packages.
