Hello, Could you make the srpm available ? I'd like to have a look and test it locally.
Thanks, Peter Peter Linnell SUSE Linux Technical Specialist Tel: 1-415-308-3037 >>> Michael MacIsaac <mike...@us.ibm.com> 2/13/2013 12:01 PM >>> Hello lists, Again, Mz is new experimental package that is a lightweight set of Linux bash scripts that provide both a CLI and a Web interface for systems management of z/VM and Linux. These scripts work well between LPARs and CECs. Again, a disclaimer: if you are expecting quality, well-tested bug-free code, then this package is not for you (you have been warned :)) If you're the experimental, "bleading-edge" type, you might want to try it out on a sandbox system. An RPM and a PDF are available at: http://sourceforge.net/projects/managing-z/ Each source file is *not* checked into svn/git as may be customary with sourceforge - too many things to worry about for now, but that will hopefully be coming.. A little background: (1) Two interns worked at IBM back in the summer of '08. They created a great Web front-end to a z/VM and Linux management interface. The problem was that the back-end data structure was simply not there. It became apparent that the data must come first - build the foundation before the facade. (2) One day I needed a chart to show the CEC - LPAR - z/VM - VirtualMachine - Linux hierarchy and started fiddling with boxes, lines and arrows. Not being a 'chart-meister', I thought how can to quickly draw a hierarchy and the Linux 'tree' command came to mind. So I created a hierarchy of Linux directories, ran "tree" and dropped the output in the chart and was about to delete the directory structure when an "aha moment" occured: Why can't the Linux file system be a database for the system z hierarchy of resources? (Neale Ferguson once called it something like "the /proc of System z resources") (3) Another influence was a comment Marcy Cortez made years ago - words the the effect of "I don't want a systems management solution that gives me islands of automation (one island per z/VM LPAR), each of which need care and feeding". (4) Many customers have asked for "no root SSH" support: If root is not permitted to SSH among systems, how does the systems management tool work? I could go on, but it is these and other "zCommunity" input/contributions/revelations from these lists, user group meetings and conferences that have driven the design of Mz. So what *is* Mz? To start with, it is a Linux RPM. A Linux system with the Mz RPM installed is considered to be an "Mz server". It requires extra privileges. Other Linux systems under the same z/VM can be managed by this server. These are considered "Mz clients", however, there is no special client code needed. The term for all Linux systems managed by Mz is nodes (clients + servers = nodes). The Secure Shell (SSH) is used for communication among Mz servers and clients and 'passwordless' SSHing is important. Except for sshd, Mz is effectively "agentless". Mz servers store data about all systems in a hierarchy of Linux directories and files. This enables fast access to data and leverages the rich set of tools that manipulate Linux file systems. There are three main branches of this "Mz tree": (1) Systems - the hierarchy of the System z resources: CECs, LPARs, z/VM systems, virtual machines and Linux systems (2) Appliances - imges of systems that have been 'captured' and can be 'deployed' to other z/VM LPARs (3) SSI clusters - for z/VM 6.2 and later, Single System Image clusters and members Multiple Mz servers can join together to form an Mz cluster. This enables cross-CEC and cross-LPAR systems management through SSH and TCP/IP (hopefully addressing Marcy's concern). All servers in the cluster synchronize with each other. When there are multiple Mz servers in the Mz cluster, each server?s system data is duplicated on each of the other servers but each Mz server "owns" the data on its LPAR. First, second and third level Linuxes are supported (though first and third have been only lightly tested). This project has been a group effort that's been percolating for years. It includes another excellent open-source tool, smaclient, written by Leland Lucius of Sine Nomine Associates. Other IBMers have contributed to the code, especially Christian Paro doing the initial capture and deploy work, and recently, Marian Gasparovic in the area of Web serving (and he has implemented some excellent ideas). While IBM OK'd the open-sourcing of this and the redistribution of smaclient, It is not an official IBM project. It's an experiment in utilizing input from the community and the proven success of the open source model. Nobody has their names in the code. While it could help IBM sales and services, it is really being made available for you the customer - to make it easier to manage your IT systems, and to make your organizations more successful and efficient.
