Nexenta v4.04 and possibly some other versions ship with VAAI in a default / disabled state. Follow these steps to Enable Hardware Acceleration:
  1. Download and extract the Nexenta vaaictl python script from the following link: http://downloads.nexenta.com/cdn/NexentaStor/utilities/vaaictl.zip
    • If the link doesn’t work, I have pasted the output of the file below.)
  2. Copy the vaaictl file to your Nexenta box to /tmp
    • Using WinSCP with windows via SFTP works well for this.
  3. SSH into your Nexenta box using PuTTY or another tool. Enter Expert mode by running:
    option expert_mode =1
    !bash

    Output:nexenta-enable-expert-mode

  4. Run the following commands to check the status of VAAI:
    cd /tmp
    chmod 555 ./vaaictl
    ./vaaictl --status
    • Output: “Current status is defaulted.”
  5. To enable VAAI, run the following:
    sudo ./vaaictl --enable
    • Output: “Changing from defaulted to enable”
  6. You can now re-check the status of VAAI:
    ./vaaictl --status
    • Output: “Current status is enabled.”
