The HP Smart Storage Administrator CLI (hpssacli) tool is unable to detect controllers on your Ubuntu Server 14.04.1 system, resulting in an 'Error: No controllers detected' message. This issue affects users who have installed the hpvsa drivers and are using the B120i controller with their system.

This error can be frustrating as it prevents you from utilizing the full capabilities of your storage setup. However, by following the steps outlined below, you should be able to resolve this issue and get your hpssacli tool working correctly.

💡 Why You Are Getting This Error

  • The primary reason for this error is that the scsi_generic (sg) driver module is not loaded on your system. Although the hpvsa drivers are installed, they rely on the sg driver to function properly.
  • An alternative reason could be that the driver for the installed controller(s) is not loaded. In this case, you would need to load the appropriate driver for your specific controller model.

🛠️ Step-by-Step Verified Fixes

Load the scsi_generic (sg) driver module

  1. Step 1: Open a terminal and run the command 'sudo modprobe sg' to load the scsi_generic driver module. This should help resolve the issue.
  2. Step 2: If you encounter any issues during this process, ensure that your system is up-to-date and consider running 'sudo apt-get update && sudo apt-get upgrade' before attempting to load the driver.
  3. Step 3: After loading the sg driver, restart your system or run 'sudo reboot' to apply the changes.

Load the appropriate controller driver

  1. Step 1: Identify the specific controller model you are using (e.g., HP Dynamic Smart Array B120i). You can find this information in your system's documentation or by running 'hpssacli controller list' to view a list of detected controllers.
  2. Step 2: Run the command 'sudo modprobe ' where is the name of the driver corresponding to your specific controller model. For example, for the B120i controller, you would run 'sudo modprobe hpB120i'.
  3. Step 3: If you encounter any issues during this process, refer to the documentation provided by HP or seek assistance from a qualified IT professional.

✨ Wrapping Up

By following these steps and ensuring that your system's drivers are properly loaded, you should be able to resolve the 'Error: No controllers detected' issue with your hpssacli tool. Remember to restart your system after making any changes to ensure the new configuration takes effect.
