When a core dump file is saved, an event message is generated. If the AutoSupport service is enabled and configured to send messages to NetApp support, an AutoSupport message is transmitted, and an automated email acknowledgement is sent to you.
The SMTP transport protocol is not supported when sending messages that include large files, such as core dump files.
You can also upload the core dump file through the AutoSupport service over HTTPS by using the system node autosupport invoke-core-upload command, if requested by NetApp support.
