VMware: vStorage API – VAAI check status

To determine if VAAI is enabled service console in ESX or the RCLI in ESXi, run the commands and ensure that the value is 1:

# esxcfg-advcfg -g /DataMover/HardwareAcceleratedMove
# esxcfg-advcfg -g /DataMover/HardwareAcceleratedInit
# esxcfg-advcfg -g /VMFS3/HardwareAcceleratedLocking

Can I check the VAAI status from the command line?

esxcfg-scsidevs -l | egrep "Display Name:|VAAI Status:"

  1. The storage is a VMax. Duncan’s post sggseuts that this is expected behaviour for all VAAI arrays.I hope to be able to test on another array but don’t have a lot of options with VAAI since I don’t work for a storage vendor.
