-With the dump-capture kernel, you can access the memory image, or "old
-memory," in two ways:
-
-- Through a /dev/oldmem device interface. A capture utility can read the
- device file and write out the memory in raw format. This is a raw dump
- of memory. Analysis and capture tools must be intelligent enough to
- determine where to look for the right information.
-
-- Through /proc/vmcore. This exports the dump as an ELF-format file that
- you can write out using file copy commands such as cp or scp. Further,
- you can use analysis tools such as the GNU Debugger (GDB) and the Crash
- tool to debug the dump file. This method ensures that the dump pages are
- correctly ordered.
