Storage system panics

About storage system panics

If your storage system has a serious problem, such as a problem with the hardware or a bug in the system software, it panics. When a system panics, it performs the following actions:

The system core is dumped into a core file, which is placed in /etc/crash.
A panic message is output to the console and to /etc/messages.
The storage system reboots.

The panic message contains important information that can help you and technical support determine what happened, and how you can prevent the panic from happening in the future.

What to do if your storage system panics

If your storage system panics, following these steps can help technical support troubleshoot the problem more quickly.

Step	Action
1	Access the panic message on the console messages or in the /etc/messages file.
2	On the web site, navigate to the Panic Message Analyzer tool at http://now.netapp.com/NOW/cgi-bin/pmsg/.
3	Copy the panic message and Data ONTAP version number into the Panic Message Analyzer tool to determine whether your panic was caused by a known software issue.
4	If the panic is due to a known issue that was fixed in a later release, and upgrading to that release is feasible, you can download the new release from the web site and upgrade to resolve the issue.
5	Otherwise, call technical support.

Note
If you have AutoSupport enabled, AutoSupport automatically alerts technical support when your system panics.
