test(breakfix): validate GB300 BMC journal log retrieval (BFX03-03) by osu · Pull Request #594 · NVIDIA/ai-cloud-validation

osu · 2026-08-21T18:41:47Z

Summary

add a direct GB300 provider for BFX03-03
discover Manager-scoped BMC Journal LogServices through read-only Redfish GETs
require a non-empty message count and exact Journal Entries source
prevent Boolean-only health-probe inference from reporting PASS
never emit BMC credentials or raw log messages

Live GB300 validation

Validated read-only on Mississippi GB300 node a05-p01-dgx-03-c01.

Manager: BMC_0
source: /redfish/v1/Managers/BMC_0/LogServices/Journal/Entries
messages returned: 1000
provider and BmcKernelLogCheck: PASS

The separate System EventLog is not accepted as BFX03-03 evidence.

Tests

53 focused provider and break-fix tests passed
all 1544 isvtest tests passed
all my-isv living examples passed
configuration validation, Ruff, and pre-commit passed

Closes #215

Live AWS IAM regression

On exact PR head 8aa986e, ran:

ISVTEST_INCLUDE_UNRELEASED=1 AWS_PROFILE=ncp-isv-lab uv run isvctl test run -f isvctl/configs/providers/aws/config/iam.yaml -- -v -s

Against AWS account 609524517695 (ncp-isv-lab, CS-Admin):

setup created a unique tagged IAM test user: PASS
credential identity and API access: PASS
teardown deleted the test user: PASS
post-run isv-test-user-* inventory: empty

This is a cross-provider regression of orchestration and provider-neutral validation. It does not replace the PR-specific Kubernetes or GB300 evidence above. Temporary credential values were not recorded.

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

The PR adds GB300 BMC Journal collection, structured evidence validation, bare-metal configuration, demo output, documentation, and tests for success and failure paths.

Changes

BMC kernel log validation

Layer / File(s)	Summary
Journal evidence validation `isvtest/src/isvtest/validations/breakfix.py`, `isvtest/tests/test_breakfix.py`	The check now requires a valid host identifier, a positive message count, and a Manager Journal Entries source path. Tests cover valid, incomplete, malformed, and invalid evidence.
GB300 Journal collection `isvctl/configs/providers/gb300/scripts/breakfix/query_bmc_kernel_logs.py`, `isvctl/configs/providers/gb300/config/bmc_kernel_logs.yaml`	The GB300 provider runs a read-only privileged helper, discovers the Manager BMC Journal, validates non-empty results, emits sanitized JSON, and handles invalid input, failures, and timeouts.
Provider contract support `isvctl/configs/providers/my-isv/scripts/breakfix/query_bmc_kernel_logs.py`, `isvctl/configs/suites/README.md`	The demo output and suite documentation use the expanded Journal evidence contract.
GB300 provider test coverage `isvctl/tests/providers/gb300/test_gb300_bmc_kernel_logs.py`	Tests cover configuration rendering, helper behavior, Journal results, structured failures, sanitization, argument parsing, and hostname validation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 249f9

The PR adds read-only GB300 BMC journal retrieval and validation, with the supplied checks and live validation passing; no actionable merge-blocking risk remains.
