Hi Dynamo - used VMconsole IP's (without deleting other entries - VMKERNEL IP's). Primus shows to use VMKERNEL IP's emc255450....
I have created Celerra NFS Exports with all required required parameteres **rw/access/root hosts (on file system in VDM and also in server_2)* Given VMKERNEL IP as shown in primus.  I am able to mount the NFS share from ESX host via VirtualCenter & also via CLI  But when i write file it gives out error as "Call "FileManager.MakeDirectory" for object "FileManager" on vCenter Server" I can't write any file.   thanks in advance.
