Can't get information about Omnipath HFI on RHEL 7.3 hosts


Recently we got some new KNL nodes and decided to try RHEL 7.3 on these hosts running the 3.10.0-514.10.2.el7.x86_64 kernel.

After installing the IntelOPA-Basic software and upgrading the firmware on the HFI and rebooting the nodes, we still can't get anything other than the following from opainfo

[root@sknl0701 ~]# opainfo

oib_utils ERROR: [7534] open_verbs_ctx: failed to find verbs device

opainfo: Unable to open hfi:port 0:1

Even though the software and firmware never complains about any errors we can still see that even after forcing dracut to recreate the system image the hfi1 driver will not load.

[root@shas0101 ~]# lsmod | grep hfi1

Hello @Wilshire461,



I am sure our Intel Omni-Path technical support team can assist you with this, however, they do not provide support through this venue.



I am forwarding your information for them to contact you directly.



Have a nice day!
