Which three commands can be used to manually generate a kernel core file? (Choose three.)
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.
