We have run multiple ConnectX-4 NICs in bonded MLAG (Arista) and VPC (Cisco) switch configurations on our NSD servers. We used to see issues with firmware versions that didn’t support the optics we wanted to use (e.g. early CX3/CX4 and Cisco 40G-BiDi). You may also want check mstflint to see whether the firmware levels match on the MLX cards, and if you upgrade firmware in some cases a power-cycle (not reboot) can be required to finish the process.

We have dual port connectx4s in our nsd servers. Upon adding a second connectx4 hba...no links go up or show "up". I have one port on each hba configured for eth and ibv_devinfo looks sane. I cannot find anything indicating that this should not work. I have a ticket opened with mellanox. On Wed, Dec 20, 2017 at 3:25 PM, Knister, Aaron S.

Is it possible the cards are trying to talk IB rather than Eth? I figured you’re Ethernet based because of the mention of Juniper. Are you attempting to do RoCE or just plain TCP/IP?

The host configuration looks sane but we seem to observe link-down on all mlx adapters no matter what we do. Big picture is that we are attempting to do mc(multichassis)-lags to a core switch. I'm somewhat fearful as to how this is implemented in the juniper switch we are about to test. _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org<https://urldefense.proofpoint.com/v2/url?u=http-3A__spectrumscale.org&d=DwMFaQ&c=jf_iaSHvJObTbx-siA1ZOg&r=STXkGEO2XATS_s2pRCAAh2wXtuUgwVcx1XjUX7ELNdk&m=Olk0lQk7rek9IplOjJ_2Vcd7P1LgVbnrSupC7O0hJHQ&s=I5Dq2T7aYvC87Wp12fsz6CRLw4uo2-RVnrnpxRYfYuA&e=> http://gpfsug.org/mailman/listinfo/gpfsug-discuss<https://urldefense.proofpoint.com/v2/url?u=http-3A__gpfsug.org_mailman_listinfo_gpfsug-2Ddiscuss&d=DwMFaQ&c=jf_iaSHvJObTbx-siA1ZOg&r=STXkGEO2XATS_s2pRCAAh2wXtuUgwVcx1XjUX7ELNdk&m=Olk0lQk7rek9IplOjJ_2Vcd7P1LgVbnrSupC7O0hJHQ&s=hxNNpOkwGQ9zRmTnM3FEo5hgnPSUsPG0FNqZbK6eA6Q&e=> _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org https://urldefense.proofpoint.com/v2/url?u=http-3A__gpfsug.org_mailman_listinfo_gpfsug-2Ddiscuss&d=DwICAg&c=jf_iaSHvJObTbx-siA1ZOg&r=STXkGEO2XATS_s2pRCAAh2wXtuUgwVcx1XjUX7ELNdk&m=Olk0lQk7rek9IplOjJ_2Vcd7P1LgVbnrSupC7O0hJHQ&s=hxNNpOkwGQ9zRmTnM3FEo5hgnPSUsPG0FNqZbK6eA6Q&e=
