Hi

Defined means represented in the Customized database (ODM), but neither configured nor available for use in the system.

Available means configured and available for use.

To make these available one can use 'mkdev -l <devicename>'

but perhaps you want to ensure these procs are healthy first;

lsattr -EH -l procnn

Check the output doesn't return 'faulty' against the corresponding processor.

Cheers, JP.
