Hi Mellanox community,
I have problems setting the NUM_OF_VFS on my ConnectX-4 Ethernet adapter (MCX416A-BCAT).
I want to use mlxconfig to set NUM_OF_VFS, but regardless if I try it under ESXi 6.5 (mft-184.108.40.206-10EM-6220.127.116.1198673.x86_64.vib) or Windows Server 2016 (WinMFT_x64_4_8_0_26.exe) I get the same error.
Here’s what I’m trying (following HowTo Configure SR-IOV for ConnectX-4 with ESX 5.5/6.0 Native (Ethernet) https://community.mellanox.com/s/article/howto-configure-sr-iov-for-connectx-4-with-esx-5-5-6-0-native--ethernet-x ):
[root@localhost:~] /opt/mellanox/bin/mlxconfig -d mt4115_pciconf0 set NUM_OF_VFS=8
Device type: ConnectX4
PCI device: mt4115_pciconf0
Configurations: Next Boot New
NUM_OF_VFS 4 8
Apply new Configuration? ? (y/n) [n] : y
-E- Parameter ’ value is smaller than minimum allowed 1
I would be happy if anybody could comment or try the same on his/her ESXi/Windows machines.
The funny thing is that I once managed to set SRIOV_EN to true and NUM_OF_VFS to 4, but I don’t remember how I did that.
Thank you and best regards
