attempting to connect my older Equallogic Array to Dell storage Manager

Hello

 

I am attempting to connect my older EqualLogic Array to Dell storage Manager, and I get the following error "Error Running method"

Unhandled Exception Running API Command [ObjectType: EmUser] [Method: AddPsGroup] [Message: javax.ejb.EJBException: com.compellent.emdatacollector.util.DataCollectorApiException: An unknown error occurred while performing the operation]

I tried adding the PS series array to Storage Manager using the Management IP and the ISCSI ip and I get the above error.

 

PS is running the latest - last firmware

SC is scv3020 running latest storage manager and SCO

any help is appreciated
