To manually generate a kernel core file in ONTAP, the following commands can be used:

1. ::> reboot --node <node_name> --dump true

What it does: Reboots the specified node and generates a core dump before rebooting.

Example Usage:

reboot --node <node_name> --dump true

2. ::> halt --dump true --node <node_name>

What it does: Halts the specified node and generates a core dump before shutting down.

Example Usage:

halt --dump true --node <node_name>

3. ::> system node panic --node <node_name>

What it does: Forces a panic on the specified node, which triggers a kernel core dump.

Example Usage:

system node panic --node <node_name>

Why Other Options Are Incorrect:

A . SP> system power cycle:

This command reboots the system from the Service Processor but does not generate a core dump.

NetApp 'Kernel Core Dump Guide' explains the use of reboot, halt, and panic commands to trigger core dumps.

ONTAP CLI Reference includes the syntax for these commands.
