  • 1.  RDM for second disk

    Posted May 13, 2010 02:23 AM

    We are converting a server that has 2 disks. The second disk is stored on an NFS volume and we want to convert the server to a VM with the second disk on a RDM. How would we do this?

    Use SAN or local storage but not NFS with RDM

    Unable to add a physical mode disk mapping (RDM) to a virtual machine stored on an NFS datastore

    Chapter 10:

    "Raw device mapping (RDM) provides a mechanism for a virtual machine to have direct access to a LUN on

    the physical storage subsystem (Fibre Channel or iSCSI only). "

    Hope that helps
