Hello Red Hat, There are two options regarding the distribution of snIPL The IBM preferred option requires a re-distribution agreement between IBM and Red Hat. Therefore feedback is required on what option Red Hat want to agree to distribute snIPL Option A.) Deliver snIPL rpm binary including two binary libraries (LPAR & zVM interfaces) required to work with snIPL. Possibility to deliver src.rpm including all binary libs for compilation. Preferred by IBM because its simple for the customer Note: Need to sign re-distribution agreement of the binary libraries with IBM Option B.) Compile snIPL with the libraries IBM provides but to package only the compiled snIPL binary into the rpm without the needed libraries for snIPL to work. The customer would have to download the libraries from IBM resource link (LPAR) and zVM (zVM) to work with snIPL in the desired environment. Not possible to deliver src.rpm also since libs for compile are not delivered. Note: No need for a re-distribution agreement for the binary libraries (LPAR & zVM interfaces) with IBM RHEL consists of open source code only - we cannot ship closed source code, or code with library dependnecies on closed-source code, in the base operating system. ------- Comment From gmuelas.com 2010-04-06 09:09 EDT------- Hello Red Hat, independent of Red Hat providing Cluster Suite / GFS2 support for RHEL on System z, this tool could still be useful for customers: Here is a copy&paste from the link provided in the first commen, about the interesting things a customer could do with this tool: snIPL - simple network IPL (Linux Image Control for LPAR / VM) is a command line tool which serves as remote linux image control using basic Support Element (SE) functions or basic z/VM system management functions (available since z/VM 4.4) 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 on System z in LPAR mode, to send and retrieve operating system messages, or to reset, activate or deactivate an LPAR for I/O fencing purposes. To compile and run snIPL for LPAR, it must be linked to the management library hwmcaapi (which can be downloaded from IBM Resource Link http://www.ibm.com/servers/resourcelink/). For further details please refer to System z Application Programming Interfaces (SB10-7030). * 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) available since z/VM 4.4. 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 V5R4.0 Systems Management Application Programming (SC24-6122) (or equivalent documentation 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 from http://linux-ha.org/download. snIPL for Stonith supports the remote image operations activate, deactivate, and reset, exploiting basic System z Hardware Management Console (HMC) and Support Element (SE) functions for Linux running in an LPAR and of basic z/VM System Management Functions for Linux running under control of z/VM. Closing this as DEFERRED since it won't go into 6.1 but will be reviewed for RHEL 6.2. |
