I have contacted the Engineering team and here's answer they give:              As the error msg implies, the operation being executed can only be supported on NFS datastore, and that is accurate (compress/decompress/fast clone/full clone of a vm can only be done on NFS datastores).               And since the user configured the VNX with only SPs and no control station, so he only has block access which means his datastore isn’t created on a NFS share, thus emerged the error.  I hope this answers your question. Please let me know if you have any more concern.
Hi all, I was wondering if anyone has come across this issue before........  We have installed the EMC unified storage manager plugin onto a vSphere installation. (As well as Storage Viewer) It is talking to an EMC VNX. There is no control workstation only the SP's  Everything seems to discover well, and registration implies we have Full Provisioning Access. The account we use to connect with has full admin rights on the VNX.  Any operation that required read access is working properly, when we try an operation that required higher privilege (such as Full/Fast Clone or provisioning storage)  the error below is displayed.  [IMAGE] Has anybody seen this before, or have any ideas?  Cheers
