vSAN Health Service - Hardware Compatibility - Controller Firmware Check (2149405)

  • 5 Ratings


This health check verifies whether the storage I/O controller firmware is compatible with the controller on the ESXi host and the version of ESXi.

If the controller is on the VMware vSAN Hardware Compatibility List (HCL) and passes appropriate controller checks, the Controller Firmware Check verifies that there the firmware version in use is on the list of supported drivers.

This check might fail if vSAN cannot fetch the firmware version, which can occur when the appropriate vendor tool (listed in the HCL DB JSON file) is not installed. In this case, the status for the controller is Unknown.

If the controller fails the hardware compatibility check and other controller checks, this check also fails. If the controller's firmware version is not listed in the VCG for this device and the ESXi version, the vSAN environment might be at risk.


If this test fails, update the HCL DB (JSON file). It is possible that the hardware or its firmware, or the release of the driver were recently added to the VCG. Then check if the appropriate vendor tool is installed, and verify that vSAN can fetch the firmware version.

For information on how to query the make, model, and version of your storage I/O controller, see the VMware vSAN Diagnostics and Troubleshooting Reference Manual.

If you cannot determine storage I/O controller information, contact VMware Support. For more information, see How to file a Support Request in My VMware.

Note: vSAN might issue a firmware HCL warning if the controller driver or driver version does not match the HCL, even though the firmware version matches. You can ignore this warning, or skip it by adding it to the silent health check list through RVC.
