I have DELL R720 poweredge server having Microsoft hyper V 2012 R2 installed. I am getting event log "Path ffffe80052200760 was removed from \Device\MPIODisk7 due to a PnP event. The dump data contains the current number of paths." For multi path IBM SDDDM has been installed. Could you please tell me What is wrong ?? Is MPIO version not compatible with IBM SAN?
