It's important to consider Firmware patches when considering an appropriate patching strategy for your systems.
In this regard, there's a new Firmware patching tab on BigAdmin which you may find useful, http://www.sun.com/bigadmin/patches/firmware/
Firmware issues are notoriously difficult to diagnose, so keeping up to date with firmware patches is a good preventative measure. Also, firmware patches also occasionally deliver support for new features, such as LDoms (on appropriate hardware).
Due to the nature of what they deliver, firmware 'patches' are not standard patches applicable using patchadd. Users must follow the install instructions in the patch README.
