Environment

VMware vSphere ESXi 5.5
VMware vSphere ESXi 6.0

Cause

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.

Resolution

To resolve this issue, upgrade the lpfc driver to version 10.2.340.18 or later, available at VMware Downloads.

 
Note: Contact your hardware vendor to determine the most recent qualified driver and firmware revisions for your server platform.
