Which type of core file is generated when a node panics?

When a node panics in ONTAP, a kernel core file is generated. This core file contains information about the kernel's state at the time of the panic and is essential for debugging system crashes.

A kernel core file is produced during a node panic to capture information about the kernel, memory, and processes that led to the crash.

The core file is stored on the root aggregate by default and can be uploaded to NetApp Support using the autosupport invoke-core-upload command.

Key Details:

A. mgwd core:

This is related to the Management Gateway daemon, which handles management traffic. It does not generate a core file during a panic.

B. user space core:

User space cores are generated for processes running in user space, not for kernel panics.

C. sync core:

Sync cores refer to synchronized cores for debugging but are not the primary type generated during a node panic.

Why Other Options Are Incorrect:

"ONTAP Panic Troubleshooting Guide" specifies kernel core files as the output of a node panic.

"ONTAP Core File Management Guide" details the handling of kernel core files after a crash.
