A set of installed internal code changes may include both concurrent and disruptive internal code changes.
Concurrent internal code changes can be activated without disrupting operating system activity on the selected Central Processor Complexes (CPCs).
In contrast, activating disruptive internal code changes will disrupt operating system activity on the CPCs.
To remove installed changes that include both concurrent and disruptive changes, and to activate their previous change levels, you will be given the options of either:
This will disrupt operating system activity on the CPCs, but all installed changes will be removed.
This will not disrupt operating system activity on the CPCs, but one or more installed internal code changes will not have all their change levels removed.
