Adding Ingrasys NAS to monitor in opmanager 11

Adding Ingrasys NAS to monitor in opmanager 11

I am trying to add a NAS storage in Opmanager for monitoring. Its getting added, but cant enable any monitor. 
I tried importing MIB and monitoring cpu and memory using NAS MIB, 
Still its not reading any information. SNMP tests passes successfuly as well.
