The Controller firmware is VMware certified health check might be unable to detect the firmware and report a warning for the 2nd(and more) controller which is managed by the sas3flash vendor tool (For Example: LSI SAS3008). A firmware version of N/A is displayed for the controller, which can be observed at both the Controller firmware is VMware certified page and Config Assist page. This is due to the sas3flash tool which can only list one controller information at a time, which caused the health check fail to retrieve controller information for all the controllers except the first one.
