This message simply alerts you that nested alarm inhibits have been detected. In the database for a SODG graphics system, alarms on a tag are inhibited by one tag, but at the same time the tag is set to inhibit alarms on another tag. The actual effect is not necessarily predictable and probably cannot be counted on. Unreliable operation of alarm inhibits is not desirable for the operators. DBDOC lists up to 10 other tags:
--Scanning database file B7_TAGDATA_TAGDATA.DBF Nested inhibit: tag GI41Q-9137 is inhibited by HS41Q-8106 but also inhibits 8 other tags: UI41Q-9118L, UI41Q-9118M, UI41Q-9119L, UI41Q-9119M, UI41Q-9120L, UI41Q-9120M, UI41Q-9121L, UI41Q-9121M
