Description

System-level diagnostics provides a menu-driven interface for tests that search for and determine hardware problems on supported storage systems. You use system-level diagnostics to confirm that a specific component is operating properly or to help identify faulty components. 

You run system-level diagnostics after one of the following common troubleshooting 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

In the event of test failures, the test results will help technical support make appropriate recommendations. The failure could be resolved by reinstalling the FRU. If the failure cannot be resolved, then there is a likely hardware failure and the affected hardware must be replaced.

 

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.
