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 Guide ( = vSAN VCG ) and passes appropriate controller checks,
the Controller Firmware Check verifies that the firmware version in use is on the list of supported drivers.
If the controller's firmware version is not listed in the vSAN VCG for this device and the ESXi version, the vSAN environment might be at risk.
This check might fail:
If this test fails, update the HCL DB (JSON file) manually.
It is possible that the hardware or its firmware, or the release of the driver were recently added to the vSAN VCG.
Then check if the appropriate vendor tool is installed, and verify that vSAN can fetch the firmware version.
How to query the make, model, and version of your storage I/O controller:
For Versions 7.0 & higher:
The Firmware of your I/O controller can be upgraded via vSphere Lifecycle Manager.
If you cannot determine storage I/O controller information, contact VMware Support.
