Firmware update of NIC makes team go degraded
I have been doing some maintenance on a Hyper-V environment and patching with Windows updates and also firmware for the hardware.
The hosts was Dell R730 with former Broadcom and now Qlogic 10 Gbit NIC´s. There are 4 10 Gbit NIC´s on every host and they are set up with one team for management and one team for VM´s.
I have done firmware update before but now there was a new version that I wanted to apply.
It tock a while before I realised that the NIC`s had changed name and thus that was why the teams was degraded, we had some discussions and the Networking guy checked his configuration more than once and we also verified the cabling on the server and then after a while I realised that the NIC actually had changed name and once adding the correct NIC´s to the teams the status changed to normal!
So when doing maintenece please check the status after updating firmware or the battle with the networking guys can end in misery on your side 😉
