System level diagnostics

  • Introduction to system‑level diagnostics
    System-level diagnostics provides a command-line 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.
  • Running system installation diagnostics
    You run diagnostics after an initial system installation to identify the version of system-level diagnostics and the supported devices on your storage system, and to verify that the installation is successful and that all hardware is functioning properly.
  • Running system panic diagnostics
    Running diagnostics after your storage system suffers a system panic can help you to identify the possible cause of the panic.
  • Running slow system response diagnostics
    Running diagnostics can help you identify the causes of slow system response times.
  • Running hardware installation diagnostics
    You run diagnostics after adding or replacing hardware components in your storage system to verify that the component has no problems and that the installation is successful.
  • Running device failure diagnostics
    Running diagnostics can help you determine why access to a specific device becomes intermittent or why the device becomes unavailable in your storage system.
