So, is it recommended to do 3par os upgrade at this environment?
Our system is in live production and i don't want to take any risk.
The way I see it, is that it is always a question about where you are, where you’re going and what have changed or been fixed along the way.
If you’re running a 8Gb gabric then you don’t have a lot of options there. 7.4.2 is as high as it gets and it has been very little critical fixes there for a while that would impact storage traffic of this kind.
If you already are at 3.3.1 then going for MU5 will not change anything support wise. On a general note without knowing anything about your environment except you have a 3PAR 8000 you want to upgrade to 3.3.1 MU5 with most likely a 8Gb FC fabric I would say that upgrading the 3PAR will generally keep you out of more trouble than it might get you into. But of course there could be other unknown factors.
There could also be reason for looking at 3.3.2 MU1, but that is another question for another day.
