Where is a kernel core file stored on a FAS9000 system that is running ONTAP...

On a FAS9000 system running ONTAP 9.12.1, the kernel core file is stored on the root aggregate. This is the default location where ONTAP writes kernel core files for system-level failures.

The root aggregate is the aggregate that contains the root volume for a given node in the cluster. This aggregate is used for critical system files and logs, including kernel core files.

When a kernel panic or other critical failure occurs, the core dump is written to the root aggregate for later analysis by NetApp Support.

Key Details:

A. on the partner root aggregate: The partner root aggregate is not used for storing core files unless explicitly configured (which is not the default behavior).

C. on the mailbox disk: The mailbox disk is used for cluster quorum and configuration information, not for storing core files.

D. on the boot device: The boot device contains ONTAP software and boot files but does not store kernel core dumps.

"ONTAP System Administration Guide" specifies that core files are stored on the root aggregate.

NetApp’s "Troubleshooting and Diagnostics Guide" confirms the default behavior for kernel core file storage.
