This is a writable flag controlling whether NM*SysMgr receives OPCOM DISKS-class messages, taking effect at the next process start-up. An administrator enables this to capture disk-related operator events separately from the numeric sHwErr and sCfgDskLimit-based monitoring. For example, enabling sCfgOpcomDisks would let the administrator see textual OPCOM notifications about disk mount, dismount, or fault events as they occur.
