Only Eth0 works

There is a cluster of 3 nodes. Each has a 2-port network card. But in the "Active Paths" can only see Eth0. And on all iSCSI disks. In Dashboard, on all nodes, in "Node statistics" I don't see any activity on Eth1. Network cards are working, checked. What could be the reason for not using Eth1 ? What can be set up ?

in Active PAths: do you see all the paths assigned to eth0 or only half the paths are assigned to eth0 and the remaining paths empty ?

if the first: are both iSCSI 1 and 2 on separate ip subnets ? do the subnets overlap ?

I see all paths assigned to Eth0. There are no empty ones. Both of the iSCSI network on the same subnet \16

in MPIO, the 2 iSCSI subnets need to be different, you may map them to same interface, but they should have non-overlapping ips else it can cause path routing issues.

Divided, made different subnets /24. Yes, Eth1 appeared. Thanks.
