However, the disk created is a Thick Provisioned Lazy Zeroed disk This is seen when a disk creation operation is initiated on a indirect volume mount by an ESXi host with NFS VAAI installed Note: Indirect volume mounts are when a volume is mounted to a LIF that is on a node that is not local to the volume. Result after disk creation:

It's recommended it be done cold by powering down the Deploy node, vMotion, then power on. (This is non-disruptive to the HA cluster) The upgraded ESX image must have the vendor RAID controller driver installed, so it will need to be downloaded from the ESX vendor. NetApp Interoperability Matrix can be used to verify the ONTAP Select/Deploy versions are supported with the new ESX image version.
