Still no solution...
NetApp has closed the case some weeks ago, because VMware is to slow, they don't want to wait anny longer. And Now VMware has closed that case too, because they don't found something in my logs and to escalate this case i must first bring the versions i used to the latest versions that are listed in the VMware HCL:
O.k. here has NetApp missed to refresh the HCL infos with the infos of their IMT to VMware, they will do that now, i hope quickly that i can reopen that case...
