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.
