800xA Redundant Aspect Connecticity Server
System: 800xA 5.1 Rev D FP4, Combined Aspect & Connectivity Server.
When Restarting Primary Server, below system alarms were generated for the Service provider in Secondary server.
1. Lock Service
2. System messages
The Alarm state for the above service is momentary i.e. back to retain state . ( refer attachment)
System status viewer for those service providers for Secondary Server were in Warning State momentarily ( couple of secs).
Note: Prior to restart of Primary Server, All servers are up & running.
It is unfortunately "business as usual" to see a few service alarms when failover takes place. Some services transits from "Service -> NOT Service -> Service" when they take over mastership from another server that is shutdown, rebooted, etc.
It would be nice if the service alarm (driven by an Alarm Expression) would have had a "Alarm Delay" to prevent these "normal" alarms during failover and fallback. Unfortunately, no such delay exists today.
Please speak with your regional ABB sales representative about enhancements.
