Resolution

*Warning: Irreparable database damage can occur. This procedure should only be performed by users familiar with SQL Server Management Studio. Databases should be backed up prior to performing this procedure.*

1. The Web Applications "Alarms" page pulls data from the vAlarmLogview in the ION_Data database
2. Query, the vAlarmLog view in the ION_Data database to determine the ID of the alarm that needs to be removed

Be sure to backup the ION_DATA database before running any SQL queries

Example:

Use ION_Data
Select * from vAlarmLog
where SourceID = 7
order by TimestampUTC desc

3. Once you have determined the ID of the alarm that needs to be removed run the following query in SQL against the ION_Data database

DELETE FROM EventAcknowledgement where EventLogID IN (1414)
