If a Server running VMware vSphere ESXi has Emulex LPe16xxx / FCoE cards installed, you experience these symptoms:
This issue occurs during error handling by the Emulex FC/FCoE (lpfc) native driver, and the driver incorrectly reports that the abort request timed out.
To resolve this issue, upgrade the lpfc driver to version 10.2.340.18 or later, available at VMware Downloads.
