Sun Cluster 3.2 Release Notes for Solaris OS

Can't Add Node to an Existing Sun Cluster 3.2–Patched Cluster Without Adding the Sun Cluster 3.2 Core Patch to the Node (6554107)

Problem Summary: Adding a new cluster node without ensuring that the node has the same patches as the existing cluster nodes might cause the cluster nodes to panic.

Workaround: Before adding nodes to the cluster, ensure that the new node is first patched to the same level as the existing cluster nodes. Failure to do this might cause the cluster nodes to panic.
