    Hi Experts,

    I have a 2 node MS SQL cluster which are running on ESXi 6.5 . It follows the standard architecture of BUS sharing SCSI controller and physical mode RDM disks .

    The base Windows OS disk ( VMDK ) is on the NFS datastore and all other RDM disk pointers are on a SAN datastore . Now I have a requirement of moving the base windows OS VMDK to new NFS datastore . Generally I do these kind of operations after taking a outage and removing the RDM disks then storage migrate only the OS then re-attach the RDM and power on the VMs . This is taking too long time to complete and alot of manual efforts when there are too many RDM disks .

    Are there any new options available ? If I power off both cluster nodes and then try storage migrate in advance mode only selecting the OS VMDK and keeping all the RDM pointers as it is helps ?

    You should be able to use Storage vMotion to move only that drive while the VM is up if it meets the requirements: Storage vMotion Requirements and Limitations
