Hi,
Yeah you are correct. Target in Fedora works .
But I am trying to do it on Ubuntu with 4.13 kernel. Both Initiator and Target are on Ubuntu.
It does not works.

Subject: [SPDK] Nvme discover using link-local
Hi ,
I am trying to discover using my IPV6 link-local address .
nvme discover -t rdma -a
fe80::0c6:11ff:fe41:0516%eth0 -s 4420.
It is unable to discover.when I check the dmesg on the initiator side I get the error "
nvme nvme0: rdma_resolve_addr wait failed (-110)."
Can someone help to resolve this issue ?
Regards
