Show Suggested Answer

Suggested Answer: B, C, D

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.

Ah, the classic 'core' command. That's like the IT equivalent of 'have you tried turning it off and on again?' But I guess B, C, and D are the real deal.

Wait, isn't there a secret command to summon the kernel genie and have them generate the core file for you? No? Alright, I'll go with B, C, and D then.
