Alarms with an invalid Source path cannot be removed from ES or AS
EcoStruxure Building Operation
Building Operation Workstation
The invalid path prevents the alarms from being deleted. In earlier releases of EBO there was an issue whereby an error could occur in the source path of an alarm if the Automation Server was renamed. Most invalid alarms observed originates from this type of error.
Use Alarms Integrity Check. Use the check on Automation Servers first, then the Enterprise Server, and finally if installed the Enterprise Central last.
Expand System and right click Alarm Control Panel and choose Advanced - Alarms Integrity Check.
The command runs quickly, there is no confirmation that the check has run but a review of the alarms will show that the invalid alarms have been removed.
