Solaris provides a useful tool to find more information about an unexpected event on your Solaris system. Once the event occurs, information is immediately captured and stored so that you may view the details. The command you can use for this is fmdump. This command can be used to solve event errors by providing addition error information. An example is as follows:
fmdump -v -u <event id>
It is often the case you will need to obtain the event id directly from the console. It should a long string of letters and numbers.
Solaris with fmdump makes it easy to view event errors.
