WalkthroughThe NVOS update flow now classifies RMS submission failures and preserves the maintenance access token after retryable failures. Invalid arguments remove the token and enter ChangesNVOS submission retry
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change enables NVOS image submissions to retry after transient RMS failures, but it still deletes the maintenance token before recording the accepted job. If the controller or persistence layer fails in that window, the update may continue without recoverable local ownership, creating a bounded merge-readiness risk that requires owner awareness or follow-up. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Persist a recoverable submission outcome before token cleanup.
These paths delete the token before an errorable state operation. If RMS accepts the request and begin, clear_nvos_update_statuses, or update_nvos_update_job fails, this handler returns without a persisted job or WaitForComplete outcome. The next iteration cannot reload the token, and restoring it can submit a second RMS job.
Record a durable submitted or cleanup-pending state before deleting the token. Reconcile token cleanup after that state commits.

Retain the rack maintenance access token when NVOS submission returns a retryable Internal or RejectedBeforeDispatch error so the next Start iteration can resubmit. Delete the token after successful submission or before an InvalidArgument transition to RackState::Error. Signed-off-by: Jay Zhu <jayzhu@nvidia.com>

Preserve the rack maintenance access token when an NVOS system-image update submission returns a retryable
InternalorRejectedBeforeDispatcherror. The nextNVOSUpdate(Start)iteration can reload the token and resubmit theApplySwitchSystemImagerequest.The token is deleted after successful submission, before transitioning to
NVOSUpdate(WaitForComplete). A non-retryableInvalidArgumenterror deletes the token before transitioning the rack toRackState::Error.Related issues

Method:

Steps:
Scaled RMS to zero and submitted an NVOS image update for one switch. NICo logged repeated
ApplySwitchSystemImagesubmission failures while the rack remained inNVOSUpdate(Start).Restored RMS. A later controller iteration resubmitted the request and transitioned the rack to
NVOSUpdate(WaitForComplete)without a missing-token error.Submitted the image update to another switch. RMS completed the parent and child jobs.
Confirmed the successful update transitioned through:
