/hold

wait for 5.1 cut.

I will verify by running pull-ci-openshift-origin-main-e2e-aws-ovn-serial-2of2 a few times the same way as we spot the issue.

Summary by CodeRabbit

• Tests

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

This repository is configured in: automatic mode

Skipping CI for Draft Pull Request.
If you want CI signal for your change, please convert it to an actual PR.
You can still manually trigger a test run with /test all

Estimated code review effort: 1 (Trivial) | ~2 minutes

🚥 Pre-merge checks | ✅ 14 | ❌ 1

❌ Failed checks (1 warning)

Check name	Status	Explanation	Resolution
Test Structure And Quality	⚠️ Warning	scale.go contains 17 Expect(err).NotTo(HaveOccurred()) assertions without diagnostic messages; all three Eventually calls have explicit timeouts.	Add operation-specific failure messages to every error assertion. Use deadline-bound contexts for direct cluster API calls if the timeout requirement applies beyond Eventually.

✅ Passed checks (14 passed)

Check name	Status	Explanation
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	The PR only deletes the dns exception. The remaining Describe and It titles in scale.go are fixed string literals with no dynamic values.
Microshift Test Compatibility	✅ Passed	The PR only removes two exception lines; it adds no new Ginkgo tests. The existing scaling test has an [apigroup:machine.openshift.io] tag.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	The PR adds no Ginkgo e2e test or test body; it only deletes two exception lines from the existing scale test cleanup.
Topology-Aware Scheduling Compatibility	✅ Passed	The commit only removes the dns exception and issue URL from test cleanup validation; it adds no manifests, operators, controllers, or scheduling constraints.
Ote Binary Stdout Contract	✅ Passed	The PR only removes a DNS exception inside AfterEach in scale.go; the changed file has no stdout or logging operations, so it does not affect the OTE stdout contract.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The commit only deletes the dns exception and issue URL; it adds no Ginkgo tests or new networking assumptions.
No-Weak-Crypto	✅ Passed	The only change removes a DNS exception and issue URL; the changed Go file adds no weak-crypto algorithm, custom crypto, or secret comparison.
Container-Privileges	✅ Passed	The commit changes only scale.go and removes two exception lines. It adds no container or Kubernetes manifest content and introduces no listed privilege settings.
No-Sensitive-Data-In-Logs	✅ Passed	The diff contains only two deleted exception lines and adds no logging or output of passwords, tokens, PII, hostnames, session IDs, or customer data.
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly identifies the removal of the OCPBUGS-86009 exception, which matches the primary change.
