After a heath collapse of our both cluster servers i was installing them on new hardware for new. It was no problem to find the iSCSI pools and volumes and i made like before 2 cluster resource objects for the volumes. First i didnt know which type of ressource object i shell create, but at last i was successful with generic IP Service. I was using the old names in the hope after it will look in the eDirectory like before the crash. The result: I can use all the cluster volumes, but only over the masterserver. I cannot create an NDS-Object what is ok, doesnt matter which server now have monuted the volumes. In this way all is complecated when the Server is changing by a problem.
