Description Tom Dale 2021-04-21 17:44:52 UTC
Document URL: 
https://docs.openshift.com/container-platform/4.6/installing/installing_ibm_z/installing-ibm-z.html

Missing section (not missing in baremetal installation)
https://docs.openshift.com/container-platform/4.6/installing/installing_bare_metal/installing-bare-metal-network-customizations.html#nw-operator-configuration-parameters-for-ovn-sdn_installing-bare-metal-network-customizations

Section Number and Name: 
section: Cluster Network Operator configuration object
subsection: Configuration for the OVN-Kubernetes CNI cluster network provider

Describe the issue: 
Configuring OVN-kubernetes networking at install time is included in bare metal installation but not Installation on IBM Z and LinuxONE .

Suggestions for improvement: 
Please add the same section, as is, to the installation for IBM Z. We currently use the same OVN-Kubernetes configuration on s390x as stated in the baremetal section, so I don't believe any other changes will be needed beyond a copy.

Comment 1 Jason Boxman 2021-07-21 19:00:07 UTC
Hi Tom,

It's my understanding we don't yet support this, but once that is the case we'll update the docs.

Thanks!

Comment 2 Dan Li 2021-07-21 19:11:19 UTC
Making Jason's comment un-private - Tom is a partner engineer and therefore cannot see the private comment with the closure reason.

Comment 3 Tom Dale 2021-07-22 14:04:42 UTC
Jason, from what I can see in the 4.8 docs "OVN-Kubernetes with an initial installation of OpenShift Container Platform 4.8" is supported on z.
See here -> https://docs.openshift.com/container-platform/4.8/release_notes/ocp-4-8-release-notes.html#ocp-4-8-ibm-z .
I thought it was only migration between network types after installation is unsupported.
Thanks

Comment 4 Tom Dale 2021-07-30 14:54:04 UTC
Reopening this bug at the public 4.8 docs now show
https://docs.openshift.com/container-platform/4.8/release_notes/ocp-4-8-release-notes.html#ocp-4-8-ibm-z
 "OVN-Kubernetes with an initial installation of OpenShift Container Platform 4.8"

But OVN is still not mentioned in the 
Installing a cluster]on IBM Z and LinuxONE for either z/VM or KVM sections:
https://docs.openshift.com/container-platform/4.8/installing/installing_ibm_z/installing-ibm-z-kvm.html
https://docs.openshift.com/container-platform/4.8/installing/installing_ibm_z/installing-ibm-z.html

Comment 5 Jason Boxman 2021-07-30 15:21:24 UTC
Thanks for reporting this Tom; We're confirming on our end whether this should indeed be in the release notes or not. Will try to get answers today or by Monday.

@sniemann, can you take a look at this BZ?

Making Comment 6 un-private as Silke may not be able to see private comment

Comment 8 Silke Niemann 2021-08-02 15:12:17 UTC
@sstout

Yes I can take care of it. Currently verifying with the IBM team if onyl the OVN subsection applies or if I can add the whole Cluster Network Operator configuration object adoc to the IBM Z assemblies.

Comment 9 Silke Niemann 2021-08-05 14:09:16 UTC
I've created a PR to include OVN in the IBM Z docs https://github.com/openshift/openshift-docs/pull/35221

@sstout Can you assign me so that I can update the status?
