Saving Crash Dumps

You can examine the control structures, active tables, memory images of a live or crashed system kernel, and other information about the operation of the kernel by using the crash or adb utilities. Using crash or adb to its full potential requires a detailed knowledge of the kernel, and is beyond the scope of this manual. See crash(1M) or adb(1)for more details on using these utilities.

Additionally, crash dumps saved by savecore can be useful to send to a customer service representative for analysis of why the system is crashing. If you will be sending crash dump files to a customer service representative, perform the first two tasks listed in "Managing System Crash Information Task Map".

The next section describes how to manage system crash information with the dumpadm command.
