Hi there

I have a HP GEN8 that is running Unraid and I am struggling to get an IP Address on the 2nd Port of the NIC. Port 1 is fine and also the ILO port.

I have made sure that the ILO port is setup to use its own port, which should leave me with Port 1&2 of the NIC for LAN/network traffic etc. When all ports have a LAN cable, all lights up and flashing.

I have double checked my DHCP server, currently my router which is getting on a bit, by using Pihole instead and still no luck.

When I look in my switch it can see the mac address of Port 2, but no IP. Unraid can also see the mac address, but says port down which is inline with no IP.

Is there some setup in the GEN8 I need to set to enable port 2 - have had a look the best I can (bit of a rookie on servers), but all seems to point to ILO setup.

Thanks in advance.

I'm using 802.3ad with link aggregation on my Switch enabled.

UnRaid itself won't request multiple IP addresses. You do need a switch with support for link aggregation and have this enabled.

As it appears you're running a UniFi network you can set up port aggregation:

First off, select your switch under devices - Click on Ports on the top tab:

Second - click on the pencil on your start port (I normally use the 2 end ports to make it simple - eg, 23 & 24):

Click on Aggregate, and select your 2 ports (the 2 ports your Microserver main LAN ports are plugged into).

In UnRaid - you need to stop your RAID then go to Settings --> Network Settings. Set the following:

Start your RAID again and you should see the following on the UnRaid Dashboard:

This essentially means:
1) Your UnRaid server will balance between the 2 NIC's making for a total of 2Gbit possible throughput.
2) Your UnRaid server will still continue to have 1 IP address. You can assign VM's and Docker containers alternative IP addresses, if required.
3) If a network interface goes down, the UnRaid server will still work over a single interface.

However you need to ensure your UnRaid server uses the configured ports on your switch going forward.
