Time to review your AIX and VIOS levels?
It is part of my job to work with customers that have hit performance problems or gone critical after a "small" configuration change ("What could possibly go wrong? - Oh nuts!").
Time and time again my first reaction is: "That AIX, VIOS and Firmware version is so old! What where you thinking?"
Avoid running in Production on your vital Servers software with issues, security holes and bugs that someone hit 2 + years ago, raised a PMR, IBM identified, temporarily fixed and released a new version of AIX including the fix.
Officially, you can get all the answers from the IBM website System Software Maps (which has recently been reviewed and updated):

It is a long time consuming task. Especially if you discover you have dozens of Server type and AIX version combinations in your computer room.
It seems to also encourage you to stick with older Technology Levels with latest Service Packs - I prefer taking newer Technology Levels.
You will have to make up your own mind.
Of course, you will be moving up to the latest Systems Firmware after its been out for 2 to 3 months!!
As every server can be evacuated using Live Partition Mobility it is a "no brainer."

Disagree!! - Please add your comments below but remember if you like hitting problems IBM fixed in 2014, having critical situations, working all hours of the day and night plus straight through the weekend then you are welcome to ignore my recommendations.
