[pca] Beginner question

[Pennington, John]

Hi Guys, 

I sort of have inherited the system admin duties as the person who used
to do it has moved on and I have some what are probably very basic
questions. 
Basically we have a sunfire 890 running Solaris 10 release 3 and my
questions are,

1) The root filesystem, and a few other file systems are mirrored; will
I need to break these mirrors before installing patches?

2) When I run PCA I am seeing something like 100 or patches come up.
Should I install all these patches or just the R-- and RS- patches?


Sorry if these seem pretty basic, as I said I'm new to this stuff. If
anyone has answers to these questions or additional tips on patching I
would certainly appreciate it.
