Re: BRMS PTF Interpretation

[PaulMmn <PaulMmn@xxxxxxxxxxxxx>]

We have 3 LPARS.  One of them 'only' controls our backup process.  We 
can update this LPAR and let the PTFs simmer for a while.  Although 
there's not a lot going on in this LPAR, it gives us a sense of 
confidence if nothing obvious falls over.

Next, we update our test system one week, and production system the 
next.  The only time we let the new PTFs simmer for a longer time is 
when we put on a cumulative patch or an OS upgrade.

As far as the BRMS updates go, unless the instructions say otherwise, 
it probably doesn't make a lot of difference if you're only a week or 
two out of sync, especially if you were in sync to begin with.
