Resolution

Q: What does the Hardware Compatibility - Controller disk group mode is VMware certified test do?

This health check verifies whether the disk group configuration, all-flash or hybrid, is compatible with the storage I/O controller and the ESXi version used in the vSAN environment. If the controller is on the VMware vSAN hardware compatibility list and passes appropriate controller checks, the Disk Group Type check further verifies that the disk group type in use for the controller is on the list of supported vSAN configurations.

Q: What does it mean when it is in an error state?

When the controller fails the hardware compatibility check, the Controller disk group mode is VMware certified check also fails.
If the disk group type for the controller is not on the supported vSAN configuration list, it means the vSAN environment might be at risk.

Q: How does one troubleshoot and fix the error state?

If this test fails, update the vSAN HCL DB (JSON file) to the latest version.
The supported vSAN configuration values for the release of the controller in use might have been recently added to the VMware Compatibility Guide (VCG).

To gather information about the controller used by vSAN, run the following command on the ESXi host:

esxcli vsan debug controller list -v true

Use the retrieved information to search for the controller's support status on the vSAN HCL.
