I work with afranchetto. You can find the event in english below :
Access to the root\MSCluster namespace was denied because the namespace is marked with RequiresEncryption but the script or application attempted to connect to this namespace with an authentication level below Pkt_Privacy. Change the authentication level to Pkt_Privacy and run the script or application again.
We have tried the command : 'sdcli hyperv list' and no result appear in the list.
I would agree with Dennis. We did see localization issues which got fixed by SD 6.2 P1 patch. We have seen these on French and German OS. So please upgrade SDW. In case you still see issues please do let us know.
