How to Test the Core Dump Setup

Before placing the system into a production environment, it might be useful to test
whether the core dump setup works. This procedure might take some time
depending on the amount of installed memory.
Before You Begin
Back up all your data and access the system console. See:
"About Communicating With the System" on page 164
What to Do
1. Gracefully shut down the system using the shutdown command.
2. At the ok prompt, issue the sync command.
You should see "dumping" messages on the system console.
The system reboots. During this process, you can see the savecore messages.
3. Wait for the system to finish rebooting.
