Issue/Introduction

These messages are due to an invalid parameter populated in the command IOCB

Environment

VMware ESXi 6.7
VMware vSphere ESXi 7.x

Cause

The qlnativefc driver is populating the nport handle in the command IOCB with an invalid value (0x1000).

Resolution

This issue is resolved in an QLogic's qlnativefc drivers 3.1.46.0 and 4.1.22.0:
