Symptoms:
When upgrading from 7.x or older version to ESXi 8.x, with a Partner Async lpfc driver version installed whose version is higher than the ESXi 8.x inbox version, the 7.x or older version Partner Async lpfc driver version will remain on ESXi 8.x.
Although these versions will work with ESXi 8.x they do not contain the complete ESXi 8.x feature capability and should be updated to the latest 8.x Partner Async driver release.
VMware vSphere ESXi 6.x
VMware vSphere ESXi 7.x
VMware vSphere ESXi 8.x
The lpfc driver installed on the system being upgraded has a higher version than the 8.x lpfc driver. ESXi will not downgrade the driver when upgrading to latest version.
