Switchless Networking Configuration for Two Directly-Attached Nodes?
To enable DA NICs to communicate with each other, simply assign IPs and subnet and leave gateway and dns server fields blank. For example
Node 1
IP: 192.168.10.1
SubnetMask: 255.255.255.0
Node 2
IP: 192.168.10.2
SubnetMask: 255.255.255.0
If NICs still try to use APIPA, then just remove device/drivers form device management and reinstall NICs drivers.
2-node S2D is broken and can’t survive second node reboot / down w/out losing pool quorum and disconnecting S2D pool. This is known issue and has to be fixed around this fall with some of the fixes (not guaranteed time frame). Example thread with an issue.
If you need 2-node switchless configuration, look at solutions, which have been designed for such setup. Like Starwind vsan
