I have a FAS2552/XenServer combo running in my environment. I currently do have 1 SVM created and have volumes attached as Xen's SR.
I created a second network interface under the same subnet but different IP, created a new SVM, copied the policies over and I'm unable to mount it. The error just states, there was an error and to check my settings. From the XenServer itself I can ping the IP that was assigned to the new Network Interface on the NetApp.
