What is the recommended process for firmware and software patching in production ONTAP?

• A. Plan Maintenance Window; Test in Non-Prod; Perform Rolling Upgrades; Verify Revision Compatibility; Monitor Health Post-Patch; Maintain Rollback Plan
• B. Patch Immediately During Peak Usage
• C. Skip Testing
• D. Disable Rollback Plan

Answer: (A)

Patching in production requires a controlled, low-risk approach that preserves service availability. Plan a maintenance window so changes are expected and communicated; test the patch in a non-production environment to uncover issues without impacting users; perform rolling upgrades so the cluster is upgraded component by component, keeping services online rather than taking the whole system down at once; verify revision compatibility to ensure the new software/firmware works with your hardware, configurations, and licenses; monitor health after the patch to catch any emerging problems early; maintain a rollback plan so you can revert quickly if something goes wrong. This combination is best because it minimizes downtime, validates that the patch behaves correctly in your environment, and provides a safety net. Patching during peak usage increases risk of disruption. Skipping testing leaves unknown issues to surface in production. Disabling a rollback plan eliminates a critical safety option if the patch introduces problems.
