For use with "October 2005 stream".
This version supersedes
- snIPL experimental (2002-03-04) for "August 2001" and "May 2002
- snIPL for STONITH (2003-07-25) for "June 2003 stream"
- snIPL V.2.0 (2004-01-30) for "June 2003 stream"
- snIPL V.2.1 (2004-11-02) for "June 2003 stream" and "April 2004 stream", as well as "October 2005 stream"

This version contains the following snIPL changes compared to snIPL V.2.1.2:
- upgrade to new version 2 plugin API of stonith (requires Heartbeat 2.0.0 and up)
- new function: snIPL --SCSIload
to load an LPAR from a SCSI-device
- new option for snIPL --dialog: --msgfilename to write operating system messages into a file
- new aliasing for image names in the configuration file
- default --timeout value for LPAR management API calls increased from 10s to 60s
Note: This snIPL version 2.1.3 supports stonith version 2 only, while
older snIPL versions support stonith version 1 only.
snIPL - simple network IPL (Linux Image Control for LPAR /
VM) is a command line tool which serves as remote linux image
control using basic S/390 or zSeries or System z9 Support Element (SE) functions
or basic z/VM system management functions with z/VM 4.4 (or higher)
on one or more images.
- snIPL for LPAR utilizes the management application
programming interfaces (APIs) provided by the HMC/SE. To
communicate with the HMC/SE, snIPL establishes a network connection
and uses the SNMP protocol to send and retrieve data. The HMC/SE
has to be configured to allow the initiating host system to access
the API. If your network is firewall-controlled, udp-port 161 and
tcp-port 3161 have to be opened between snipl-invoking Linux system and HMC/SE.
In this mode snIPL can be used to boot Linux for S/390, zSeries, or Sytem z9
in LPAR mode, to send and retrieve operating system
messages, or to reset, activate or deactivate an LPAR for I/O
To compile and run snIPL for LPAR, it must
be linked to the management library hwmcaap (which can be downloaded from
IBM Resource Link http://www.ibm.com/servers/resourcelink/).

- snIPL for VM serves as remote control of basic z/VM
system management functions. It can be used to reset, activate or
deactivate a Linux/VM image for I/O fencing purposes. In this mode
snIPL utilizes the System Management
Application Programming Interfaces (APIs) of z/VM 4.4 (or higher).
To communicate with the z/VM host, snIPL for VM establishes a
network connection and uses the RPC protocol to send and retrieve
data. To compile and run snIPL for VM, the RPC protocol
specification DMSVSMA.X has to be copied to the Linux system
running snIPL (usually into /usr/share/dmsvsma/).
For further details please refer to
z/VM V4R4.0 Systems Management Application Programming
z/VM V5R1.0 Systems Management Application Programming (SC24-6122-00)
(from the z/VM website: http://www.vm.ibm.com).
- snIPL for STONITH (Linux Image Control - Virtual Power
Switch) is an external stonith plugin.
STONITH (Shoot The Other Node In The Head) provides an extensible
interface for remotely powering down a node in a cluster. It is part of
the Heartbeat framework of the High Availability Project (http://linux-ha.org).
http://linux-ha.org/STONITH gives a general description of the
STONITH technique. The latest STONITH release can be downloaded
snIPL for Stonith supports the
remote image operations activate, deactivate, and reset, exploiting
basic S/390, zSeries, or Sytem z9 Hardware Management Console (HMC) and
Support Element (SE) functions for Linux running in an LPAR and of
basic z/VM 4.4 (or higher) System Management Functions for Linux running under
control of z/VM.
(in addition to the snIPL command line tool):
To compile and make use of the STONITH plugin lic_vps, package
heartbeat has to be downloaded from http://linux-ha.org/download
