Hoping somebody can shine some light on an issue I am seeing with our FAS2040 and ESXi 5 host with VAAI. Issue being that it appears not to be working. When viewing the storage array through vCenter using the VSC the array shows as "Enabled" for "VAAI Capable". I am presenting two FC LUNS from the array to one of my hosts that I am doing the testing on. I have confirmed that the correct ESXi modules are being loaded (esxcfg-module -l |grep vmw_vaaip_netapp) on the host as well as confirmed that the devices are showing as "Supported" for VAAI (esxcfg-scsidevs -l | egrep "Display Name:|VAAI Status:"). So from this I am thinking I am good. I fire up ESXTOP/RESXTOP and go to the Device screen (u), remove all fields except for DEVICE and VAAISTATS (f). I run a Storage vMotion job of a VM from one LUN to the other expecting to see changes in the counters for CLONE_RD and CLONE_WR but get nothing.
I have read through TR-3886 which covers the VAAI aspect for NetApp and believe everything has been configured correctly. HELP!
