FC HBA storage adapter listed twice?

[WuGeDe]

Hello guys

I have an ESXi where my FC HBA is listed as vmhba0 and vmhba1 and also a second time as vmhba64 and vmhba65.

Why is that the case?

Please have a look at my attached pictures.

ESXi is running 7.0.1, 17551050 and vcsa is 7.01 17327586

Thank you much for help!

Has the host been upgraded recently, then you may have hit a known issue. Although it is possible to fix this using appropriate commands (not officially supported), it's recommended that you open a support case to have it fixed.

Hello @a_p_ 

Yes I patched this host to the latest patches / updates via Lifecycle Manager.

What I'm thinking of is the issue discussed at https://communities.vmware.com/t5/VMware-vSAN-Discussions/Strange-device-controller-phenomenon-after...

Again, in case that's it, then rather than trying to fix the issue yourself, consider to open a support case with VMware.

Yes @a_p_  I found that vmware KB2127274 also. But it only refers to versions prior to 6.7.

If I look at my esx.conf file I can not find these duplicate entries there mentioned in the KB.

I opened a case and if I got a solution post it here.

That's why I pointed you to the other discussion. With vSphere 7 some settings are now stored in the ConfigStore rather than the esx.conf file.

Yes you are right. I agree.

Here is the answer I got on my case:

Below is the reply from our engineering team:

This is expected for qlnativefc driver. qlnativefc driver uses one port to support scsi and nvme device. It will create NVMe adapter and scsi adapter for same port.
The wwnn and wwpn are same for NVMe and SCSI adapter,

If you don't want to use NVMe device, it can set parameter as:

$esxcfg-module -s 'ql2xnvmesupport=0' qlnativefc
$reboot

It will disable nvme adapter.
