failed to obtain IP from DHCP with infiniband NIC

[Hamdy Khader]

DHCP option used to be 'client-id' and that causes issues with infiniband.
For infiniband we need to add 'client-id' DHCP option to get IP address, neutron change 'client-id' to number 61 to meet rfc4776.

    Use Param DHCP_OPT_CLIENT_ID_NUM

    Ironic is sending 'client-id' as a number (61) to meet rfc4776 [1],
    due to this change Neutron DHCP should support this option as well.

Can you help me understand the importance of this in regards to backports? Are you running into this problem on Pike and things are unusable?

[Hamdy Khader (hamdyk)]

We only had this issue after this change:
https://github.com/openstack/ironic/commit/228a2a7885e1b04d4180fe8daa2992884decaf6d

since it is present in branches "stable/queens" and was backported to "stable/pike" (https://github.com/openstack/ironic/commit/78c4d016461bf88030e4e304b912bd7a1f711815)

we need to do the same fix master (done) and backport to queens and pike.

[Brian Haley (brian-haley)]

Ok, thanks. So I will set this to High based on the Ironic bug that broke (fixed?) things, https://bugs.launchpad.net/ironic/+bug/1717236

    Add DHCP_OPT_CLIENT_ID_NUM

    For Infiniband support, Ironic needs to send the 'client-id' DHCP option
    as a number in order for IP address assignment to work.
    This is now supported in Neutron, and can be specified as option number
    61 as defined in RFC 4776.
