Use the vSphere CLI to verify the hardware acceleration support status of a particular storage device. This command also helps to determine which VAAI filter is attached to the device.

Run the esxcli corestorage device list --d device_ID command.

The output shows the hardware acceleration, or VAAI, status that can be unknown, supported, or unsupported. If the device supports the hardware acceleration, the output also lists the VAAI filter attached to the device.
