We have Mellanox Infiniband ConnectX-5 VPI adapter card to test rdma, now i am in trouble.
1 i find when use command ifdown, the IP disappeared, but the connection eastablished will have no affect, still have IO throgh port.
Is there a solution to archive the effect like ifdown/ifup on Ethernet (easily disconnect the network and rdma IO)?
2 well, i find a solution, use command ibportstate lid port disable ，it is really works, at lease no IO anymore.
Unfortunately, this port can not recover to link-up, even after reboot.
ibportstate lid port enable not work and mlxlink not work yet.
How to make port link-up again?
