snIPL (simple network IPL) is an experimental interactive tool which serves as remote control of basic S/390/z800/z900 Hardware Management Console (HMC) and Support Element (SE) functions. snIPL can be used to boot Linux for S/390 or zSeries in LPAR mode, to send and retrieve operating system messages, or to deactivate an LPAR for I/O fencing purposes in a clustered environment.
Note: snIPL can not be used to control VM-guests remotely.

To allow remote access, the SE has to be configured properly (see SB10-7030, "zSeries 900, Application Programming Interfaces", available at To compile and run snIPL, it requires to be linked to a management library which comes with the HMC software for various operating systems, see SB10-7030 for further details. The library itself is maintained by the IBM HMC team. Versions of the library for Linux for S/390 are available on a customer request basis. Please contact your local IBM representatives for further inquiries.

Please read the README and manpage of snIPL enclosed in the tarball for further information and restrictions.
