I have HA running in a VM. I am wanting to move it to another subnet so am adding a 2nd NIC so that once up, I can remove the one that is linked to the old subnet.
I have added the NIC in the VM but not seeing it in HA.
When I ssh into HA I get the following:
[core-ssh ~]$ ip link show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
20: eth0@if21: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP
link/ether 02:42:ac:1e:21:01 brd ff:ff:ff:ff:ff:ff
So the 2nd NIC is not seen.
But the below indicates that it is there (got this command from googling)
[core-ssh ~]$ dmesg | grep -i "eth1\|enX1"

and HA can see the NIC as per the below:
