Well for patching, first thing you learn is backup then you learn repositories (IPS).
Having local repositories is a major advantage.
In Solaris 11, if you do major patching the pkg will patch the inactive boot environment then it will be active after next reboot (utilizing zfs clone ability on root zpool).
That helps you, since if things go berserk, you can always reboot the host and revert to old environment.
On HPUX, the tool for patching is swinstall and for backup/repositories it's Ignite.
Great help here is HPSIM tool with SWA (Software assistant), which generates reports what to patch, connecting to HP site and your HP machines.
For linux, for major kernel patches, you will have your last couple of kernels to boot from if things go wrong. For backup i use tar/gzip (read full drive backup for your distribution).
And the final piece of advice (not OS related) is to have test environments to try patching first.
Nothing can substitute that.
Hope that helps

Peasant.
