Kernel panic settings
Set the attribute /sys/firmware/shutdown_actions/on_panic to reipl to
make the system re-IPL with the current re-IPL settings if
a kernel panic occurs.
For Linux® in LPAR mode and Linux on z/VM®, you might want to trigger a system dump in response to a kernel panic. See also the description of the dumpconf tool in Using the Dump Tools, SC33-8412 on IBM® Documentation at:
