S390 and zSeriesspecific Linux commands

Mainframe distributions of Linux provide the commands common to all hardware platforms. These distributions also provide a unique set of commands that allow Linux to interact with the host operating system and virtualized devices. 20.8.1 Packages specifically for the mainframe Red Hat Enterprise Linux and SUSE Linux Enterprise Server each provide packages with tools and utilities specifically designed to work with the mainframe. The packages are - yast2-s390 (graphical interface for tools)...

Installation methods and techniques

There are three basic installation methods for Linux on mainframes. These methods are Installation as a native operating system. No other LPARs can be defined. All resources are dedicated to Linux. Linux cannot take advantage of virtualization techniques. This is not available on all IBM mainframes. Installation into a logical partition (LPAR). Linux in an LPAR is typically used when the single Linux server can process a large, critical workload. For example, SAP and IBM Lotus Domino servers...

Creating a Porting Project Schedule

Bernoulli Effect

When creating the porting schedule, consider all risks, including technical and business-related issues. In terms of technical issues, common things such as resource availability, hardware availability, third-party support, and Linux experience need to be considered. On the business side, issues such as reorganizations, relocations (moving offices), customer release dates, and business objective changes may affect the porting schedule as a whole. These technical and business issues will create...

POWER technology platform service and productivity tools

There are various hardware service diagnostic aids and productivity tools available for server i5 and server p5 and JS20 blade systems running Linux. These service and productivity tools perform the following functions - Access POWER technology-based platform features that are provided by the system's firmware - Gather hardware inventory and microcode level - Access system boot lists, LEDs, reboot policies, and so on from the operating system command line - Communicate with an attached Hardware...

Assemble the stakeholders

As the name implies, these are the people with a stake in the migration. This group is not limited just to the people responsible for directly maintaining the systems. End users of the services (especially if it is a client workstation) and business managers have an interest in a successful move that meets the goals of the organization. A meeting of stakeholders (or representatives of large groups of stakeholders) is a good way to set expectations and to perform some of the other planning...

Defining Project Scope and Objectives

Project scope is defined as the specific endpoints or boundaries of the project as well as the responsibilities of the project manager and team members.5 A clearly 5 Radical Project Management, Rob Thomsett, 2002, Prentice Hall defined project scope ensures all stakeholders (individuals and organizations involved in or that might be affected by project activities project team, application architect, testing, customer or sponsor, contracts, finance, procurement, contracts and legal) share a...

Analysis

There are two views in the analysis step of the porting process a project management point of view, and a porting point of view. From a project management point of view, analysis is the step that assesses the various porting issues and risks identified in the preceding step and what impact they bring to the porting project as a whole. The analysis step involves the formulation of the project plan, which includes identifying scope and objectives, creating work schedules, procuring resources...

Create a virtual IO server partition profile

The virtual I O server is the most important partition you will create because it provides the virtual adapters to the other client partitions. After the system is connected to the HMC, you can proceed with partitioning it. This section covers the process of creating the virtual I O server partition using an HMC. 1. To begin, right-click Partitions under the system name (from the HMC) and select Create Logical Partition to start the Create Logical Partition Wizard. 2. Select Virtual I O server...

Solaris Volume Manager to Linux LVM

The Sun Solstice DiskSuite SDS has been changed to Solaris Volume Manager SVM since the introduction of Solaris 9. The functionality and concept is still very much the same, but SVM introduces the new feature called soft partitions. All of the following references to SVM refer to both SDS and SVM. Where appropriate, a more detailed distinction between SDS and SVM is noted. Table 4-7 illustrates volume management commands. Table 4-7 Volume management commands Table 4-7 Volume management commands...
