Fixed In Version:	rhel-system-roles-1.18.0-1.el9	Doc Type:	Enhancement
Doc Text:	.Users can create connections with IPoIB capability using the `network` RHEL System Role The `infiniband` connection type of the `network` RHEL System Role now supports the Internet Protocol over Infiniband (IPoIB) capability. To enable this feature, define a value to the `p_key` option of `infiniband`. Note that if you specify `p_key`, the `interface_name` option of the `network_connections` variable must be left unset. The previous implementation of the `network` RHEL System Role did not properly validate the `p_key` value and the `interface_name` option for the `infiniband` connection type. Therefore, the IPoIB functionality never worked before. For more information, see a README file in the `/usr/share/doc/rhel-system-roles/network/` directory.	Story Points:	---

Description Wen Liang 2022-05-16 23:18:56 UTC

+++ This bug was initially created as a clone of Bug #2086869 +++

Description of problem:

This is more like the RFE than an bugfix. The following are the sub-tasks:

1. Add the infiniband setting description, the integration test.
2. Improve the infiniband setting validation.
3. Change the default value of `p_key` setting.

--- Additional comment from Rich Megginson on 2022-05-16 18:02:22 UTC ---

We will also need to add `--skip-tags tests::infiniband` to our downstream CI tests.

Comment 6 Zhiqian Guan 2022-06-02 11:00:27 UTC

Ran tests_infiniband_nm.yml on an RHEL9.1 control host, target RHEL7.9, 8.6, 8.7, 9.0, 9.1 as managed host, detailed logging can be found in the attachment

The feature itself is good. But there's an issue about the test playbook. When running the test playbook against an RHEL7.9 node, the mode/pkey of Infiniband cannot be found in the output of "ip" command, so that the testplaybook will fail in this case, but the configuration is fine. We only need to check the mode and pkey of interface by using "cat /sys/class/net/ib0.000a/pkey" and "cat /sys/class/net/ib0.000a/mode". 

I've attached the modified test playbook for your reference. 

Mark this as VERIFIED as the feature is good. I'll open another bug to track the test playbook issue.
