if you are having system filesystems (/ /usr /var ...) on software RAID1 devices, best practise is to split mirrors and have most recent actual copy of the system (or create current ZFS snapshot if using ZFS on root),patch it in single user mode or use Live Upgrade functionality and create alternate boot environment and patch the ABE on running system (you can find various info in Oracle Docs or get inspired by various blogs:http://nilesh-joshi.blogspot.com/2011/10/oracle-solaris-patching-using-live.html). I always patch kernel and other system components using PCA patching utility - have a look on project homepage http://www.par.univie.ac.at/solaris/pca/ it's really advanced and helpful tool. It can save you lot of time when solving dependecies and also downloading the patches.
