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?
1. Why do you IPL at all?
2. Why don't you perform IPL by yourself? Hint: remote access to HMC.
3. What's the problem with the operators? I can see the following
possibilities:
- Nobody's perfect, they simply made a mistake, the situation never
happened again.
- They can't read, don't understand, are drunk...
- They don't have procedures and clearly defined tasks (i.e. using
procedure ABC, IPL system XYZ on LPAR 123)
