Update Storage Controller Drivers and Firmware

You can use Virtual SAN to update old or incorrect drivers and firmware on storage controllers.

Configuration Assist verifies that your storage controllers use the latest driver and firmware version according to the VMware Compatibility Guide. If controller drivers or firmware do not meet the requirements, use the Updates page to perform driver and firmware updates.

Prerequisites

The controller Management tools for your storage devices must be present on the ESXi host.

Procedure

1. Navigate to the Virtual SAN cluster in the vSphere Web Client.
2. Click the Configuration tab.
3. Under vSAN, click Updates to review the components that are missing or ready to install.
   The Updates page lists any missing firmware and driver components.

   Note: If the controller Management (Mgmt) tool is not available, you are prompted to download and install the Management tool. When the management tool is available, any missing drivers or firmware are listed.
4. Select the component you want to update, and click the Update icon to update the component on the ESXi hosts in your cluster. Or you can click the Update All icon to update all missing components.
   Confirm whether you want to update all hosts at once, or if you want to use a rolling update.

   Note: For some management tools and drivers, the update process bypasses maintenance mode and performs a reboot based on the installation result. In these cases, the MM Required and Reboot Required fields are empty.
5. Click the Refresh icon.
   The updated components are removed from the display.
