Support for Sun StorEdge T3 disk trays. 1.16a level firmware, patch number 110760-01 is required to use a Sun StorEdge T3 disk tray in a cluster. See Appendix A, Installing, Configuring, and Maintaining a Sun StorEdge T3 Disk Array for hardware installation and maintenance procedures.
Support for Instant Image 2.0 coexistence with Sun Cluster 2.2 in Solaris 2.6 and Solaris 8 environments. See "Patches" for a list of patches required to implement this feature.
Support for Solaris Resource Manager 1.0 coexistence with Sun Cluster 2.2 in a Solaris 2.6 environment, and support for Solaris Resource Manager 1.2 coexistence with Sun Cluster 2.2 in a Solaris 8 environment. See "Patches" for a list of patches required to implement this feature. Read the Solaris Resource Manager 1.2 Documentation Errata in the Solaris Resource Manager 1.2 Collection on http://docs.sun.com for information about this coexistence feature. This Errata is applicable to both the 1.0 and 1.2 versions of Solaris Resource Manager.

Enhancements to Process Monitoring

The process monitoring daemon (pmfd) in Sun Cluster has been enhanced to provide greater control of process monitoring:

pmfd can now be used to restrict monitoring to a subset of all processes. Therefore, any performance impacts associated with monitoring can be limited to only those processes being monitored.
pmfd is less likely to reach resource limits when the number of processes monitored is reduced.
The new features can be used to temporarily switch off monitoring to allow processes to be traced (with truss or pstack, for example) for diagnostic purposes.
pmfd can now correctly identify a failed process, even if its descendants are still running.

The new features are implemented through the -C option to pmfadm(1M), and are described in a revised pmfadm(1M) man page. The new option and revised man page are available for Sun Cluster 2.2 in cluster framework patch 109208, and for Sun Cluster 2.1 in patch 105458-15. Obtain the patches from your service provider or from the Sun patch web site, http://sunsolve.sun.com.
