Description
System-level diagnostics is a powerful tool that provides a command-line or menu-driven interface for conducting tests to identify potential hardware issues. Utilizing system-level diagnostics can help confirm the proper operation of a specific component or identify faulty components.
Run system-level diagnostics in the following situations:
- Initial system installation
- Addition or replacement of hardware components
- System panic caused by an unidentified hardware failure
- Access to a specific device becomes intermittent or the device becomes unavailable
Do I need to run System-level diagnostics?
No, you do not need to run diagnostics
- ONTAP systems perform various Field Replaceable Unit (FRU) checks during the boot process
- Once booted ONTAP includes Health monitors
- Health monitors proactively monitor certain critical conditions in your cluster and raise alerts if they detect a fault or risk.
- If there are active alerts, the system health status reports a degraded status for the cluster.
- The alerts include the information that you need to respond to degraded system health.
