Testing 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.
Back up all your data and access the system console. See:
■ “About Communicating With the System” on page 24
▼
To Test the Core Dump Setup
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.
