Chassis data store on restart

Hi ,

I am trying to retrieve all chassis objects on restart of vcenter server.

Hence I am putting each chassis object info (chassis name and server type) in file.Apart from these details do i need to store vimobjectRef.If yes, then how it will be retained on server restart?

When vcenter server is resarted,i am reading file content from file.

Using this chassis object info from file,i want to re-construct all the chassis object.How can I do so?

In this case for chassis object creation,the flow should it be from ui-service layer or can i create object in service layer itself(then how object context will be reachable to ui).

Since I am using object context for further reference.

Thanks in advance.
