What steps verify system health after an ONTAP upgrade?

• A. Check cluster and node status, verify service availability, confirm replication relationships, and review logs for errors or warnings.
• B. Run only hardware diagnostics and ignore software services.
• C. Reboot every node and reformat disks.
• D. Immediately decommission all volumes to ensure clean state.

Answer: (A)

After an ONTAP upgrade, the goal is to confirm the system is healthy and ready for normal operation. The best way to do that is to verify that the cluster and each node report a healthy status, and that core services are up and reachable. You also want to ensure replication or data-protection relationships are still intact and up to date, so there’s no hidden risk to data protection after the upgrade. Finally, reviewing the system logs and event messages for errors or warnings helps surface any post-upgrade issues that aren’t obvious from status alone. This approach covers operational readiness, service availability, and data protection, plus it catches issues early by surfacing warnings in logs. The other options are not suitable because they focus on hardware checks only, involve destructive actions, or discard data without justification.
