Hello, How to get device entry in /dev ? I have installed MCX353A-FCBS into my VMware ESX server. I see it as ethernet 40G adatper.

I have installed MFT tools:

https://community.mellanox.com/s/article/how-to-install-mellanox-firmware-tools--mft--on-vmware-esxi-6-5-6-7

but I don’ t have any mellanox device in /dev directory. Neither /dev/mst/* or anything similar.

I have already tried different ESX versions 6.5 U1, 6.7.0, 6.7.0 U1. Also tried to install original Mellanox drivers instead of ones included in ESX. Stil problem is the same - there is dev entry.

Otherwise /opt/mellanox/bin/mst status shows device

MST devices:

mt4099_pciconf0

mt4099_pci_cr0

and

[root@esx1:/opt/mellanox/bin] ./mlxfwmanager

Hello Rihards,

You can see the device with:

esxcli network nic list

or

lspci -v | grep Mellanox

or

mst status -v

But the device is not listed under /dev and ESXi doesn’t have /sys.

Is there something you are trying to do? What are you looking for?

Many thanks,

~Steve
