VM's are located on VMFS Datastores not NFS

Are you adding new or existing RDM?

Is the LUN you are pointing at also in use by another virtual machine?

[supermancsm]

this is a new LUN

It doesnt matter with new or existing, still get the same error

[udaykumar-blr]

did you select an existing datsatore as a pointer LUN?.

even though the RDM LUN stores data in it, the initial reference should happen via existing vmfs LUN, which is attached to esx.
