There are no errors logged in the MDM show events (/opt/emc/scaleio/mdm/bin/showevents.py).

 

Impact

No impact

Cause

A false alert is shown by the PS when an RCG is in a Switchover/Failover state.

Resolution

If, after performing the Switchover/Failover, no errors are shown in the MDM show events, it is safe to ignore the alert.

To remove the alert, perform a Restore/Reverse replication. See the documentation (Getting to Know Dell PowerFlex) for more details on restore and reverse replication.
