After performing an ONTAP upgrade, which verification step confirms success?

• A. Confirm cluster health status and component health
• B. Verify license activation only
• C. Check only fan status
• D. Review upgrade logs exclusively

Answer: (B)

The key thing being checked after an ONTAP upgrade is that the system has accepted and activated the new licenses that come with the upgrade. When licenses for the new features are activated, it shows the system is not only running the newer code but also has the necessary rights to use the updated capabilities. Without license activation, you might have the upgraded software present, but some features could be unavailable or blocked, which means the upgrade hasn’t fully taken effect.

While cluster health and component health are important for ongoing operation, they don’t by themselves prove that the upgrade completed and the new features are enabled. Logs can help troubleshoot what happened during the upgrade, but they don’t alone confirm success. Checking other aspects like fan status is not relevant to confirming the upgrade itself.

So, verifying that licenses have activated is the clearest signal that the upgrade process has completed successfully and the system is ready to operate with the new version and features. To perform this check, one would typically confirm the new licenses are active on the cluster (for example, via the license show/verification commands).
