OME 2.0 sending Status Unknown alerts
After OME 1.3 -> 2.0 upgrade started to receive "Device has changed status to Unknown" alerts.
In couple of seconds to 15 minutes devices automatically return to Normal state in OME.
Devices are PowerEdge servers with OMSA installed and discovered thru in-band SNMP only.
There are no network disruptions or server/service restart when this happens.
Any ideas? Thanks,

mmmm, should not be any new changes in this area.
These state change alerts are often only used by folks that don't have SNMP alerting enabled. So one option is to turn off Internal Health Alerts. The reason is that your SNMP alerting is sufficient to let you know a device state has changed.
Is this a WAN device or LAN?
Some folks will see this kind of behavior on a slower/intermittent WAN connection. If this is the case and you want to leave internal health alerts enabled, you might go to the ICMP settings on the first page of the discovery wizard and increase timeout/retry for these WAN devices.
Hope that helps.

I have both types of devices in OME - LAN and WAN.
Unknown status alerts were received for both types of devices.
As you suggested I turned off Internal Health Alerts (and Internal Connection Status Alerts).
Now Unknown status alerts do not seem to come in, but I am not receiving important alerts anymore.
For example on a WAN device, PowerEdge r720xd server monitored over OMSA and SNMP, local disk failed, the server is in Warning state in OME, but no alert was received.
Same for a LAN device - Equallogic PS monitored over SNMP, no alert received on disk failure (however state changed to Warning in OME).

Right, so we need to confirm that your R720XD is configured to direct it's SNMP alerts to the IP address of the OME Server. Can you check this?
Same for Eql PS....it must be configured to direct SNMP traps to the OME server.
If you have confirmed this, then we'd need to run the Dell Troubleshooting Tool to test the SNMP traffic coming in on the OME server, say with a test or sample SNMP trap. Some folks use Wireshark to confirm as well.
Thanks,
