Select Set Service Lock to acquire the service lock for the specified location. The service lock must be set before the power domain corresponding to the specified location can be powered off or on.
Caution: The service lock is the mechanism that prevents power from inadvertently being applied to a locked FRU location. Since multiple users can connect to a single HMC through remote clients, a user could free the service lock obtained by another user who is currently in the middle of a repair action, resulting in a safety issue.
