Software Patches

After installing each software product, you must also install any required patches. For proper cluster operation, ensure that all cluster nodes maintain the same patch level.

• For information about current required patches, see Patches and Required Firmware Levels in Sun Cluster Release Notes or consult your Sun service provider.

• For general guidelines and procedures for applying patches, see Chapter 11, Patching Sun Cluster Software and Firmware, in Sun Cluster System Administration Guide for Solaris OS.
