PowerEdge: How to Resolve ESXi 7.0 U3 FC HBA Device Enumeration Issue

Summary: Upgraded ESXi 7.0 U3 FC HBA device found additional vmhba 64,65,66,67 but no physical impact. To identify whether it is an HBA Enumeration problem, you have to compare between the old and new logs to verify whether there have HBA device name change happened. ...

Instructions

  • Using Dell EMC customized VMware ESXi 7.0 U3 A04 image
  • Build 19193900
  • Can see vmhba2, vmhba3, vmhba4, vmhba5 PCI device id same as vmhba64, vmhba65, vmhba66, vmhba67 which identity this is not enumeration
  • If those HBA adapters before upgrade are using vmhba2,3,4,5 and then after upgrade you cannot find vmhba2,3,4,5 but only vmhba64,65,66,67, then this is enumeration change problem.
  • There has new qlnativefc driver which starting to support nvme over fiber channel in ESXi 7.0 and later
  • localcli_nvme-adapter-list can found vmhba64, vmhba65, vmhba66, vmhba67

Resolution# This is an expected behavior.


Workaround
When using the qlnativefc Driver, to work around this issue if you do not want to use NVMe devices:

1. Set the parameter by running this command:
 

esxcfg-module -s 'ql2xnvmesupport=0' qlnativefc



2. Then reboot. This disables NVMe support. 
 

Note: Marvell FC NVMe adapter and NVMe LUN devices which connected to adapter will not be accessed.
