Manage core dumps (cluster administrators only)

Contributors

When a node panics, a core dump occurs and the system creates a core dump file that technical support can use to troubleshoot the problem. You can configure or display core dump attributes. You can also save, display, segment, upload, or delete a core dump file.

You can manage core dumps in the following ways:

  • Configuring core dumps and displaying the configuration settings

  • Displaying basic information, the status, and attributes of core dumps

    Core dump files and reports are stored in the /mroot/etc/crash/ directory of a node. You can display the directory content by using the system node coredump commands or a web browser.

  • Saving the core dump content and uploading the saved file to a specified location or to technical support

    ONTAP prevents you from initiating the saving of a core dump file during a takeover, an aggregate relocation, or a giveback.

  • Deleting core dump files that are no longer needed

Note

AFF A220, AFF A800, FAS2720, FAS2750, and later systems store core dumps on their boot device. When NetApp Volume Encryption (NVE) or NetApp Storage Encryption (NSE) is enabled on these systems, the core dump is also encrypted.
