First, I would respectfully submit that this not an operator problem.
Operators make mistakes and any dependence on operators accepts that as
a consequence.
To eliminate the mistakes, you must eliminate the operators.
That said, I have a few tricks that help minimize my screw ups:
1. You can lock out 'disruptive' LPAR changes. I like to keep my
production LPARs locked.
2. Use only activation profiles for ordinary IPL's.
3. Changes to an activation profile are made by a qualified individual.
I am told that activating a profile is the same as a
deactivate/activate/IPL sequence. For us, that does not add any
noticeable time to the IPL sequence and eliminates a decision point.
Plus, there is assurance that LPAR changes are picked up.

Subject: HMC Management Best Practices
One of our recurring problems is with the management, i.e. proper use of
the HMC by the operators when they perform their job responsibilities;
1) IPL an lpar with a specific load address/load parm.
2) Change lpar settings, storage, cpu's, weights,...
We have had many instances of wrong lpars being deactivated and then
ipled incorrectly, changes to ipl environments not being applied
correctly...
What are some best practices that you use to prevent these and other
operator errors while performing HMC tasks?
