A Guide to Migrate Hardware Diagnostics from EMS and STM to WBEM-Based Solution HP-UX 11i v3 Abstract This document briefly introduces you to the next generation hardware diagnostics, System Fault Management (SFM). It describes how to migrate from EMS & STM based hardware monitoring solution to WBEM-based hardware monitoring solution. It contains information about WBEM providers that are used to obtain information about Direct Attached Storage and IO devices on a managed system.

1 Introduction Traditionally, hardware resources on HP-UX systems were monitored using the Event Monitoring Service (EMS) based hardware diagnostics solution that provided an array of EMS monitors to monitor the system hardware. It also provided tools to check the status and property information of hardware components and perform various tests on the hardware components. However, with increasing complexity of hardware in the data center, there is a growing demand to simplify IT infrastructure management.
Introduction to WBEM-Based Hardware Diagnostics Solution The WBEM-based hardware diagnostics solution includes the System Fault Management (SFM) software and WBEM providers. SFM is a collection of tools used to monitor the health of HP servers running HP-UX. It retrieves information about a system’s hardware devices such as CPU, memory, power supply, and cooling devices. It operates within the WBEM environment, an industry-wide standards-based initiative to aid the management of large scale systems.
The WBEM-based hardware diagnostics solution is available on the OE media and on the Web.
This section includes the following topics: • “Terminologies Used in EMS & STM based and WBEM-Based Solution” (page 7) • “Comparison of EMS & STM based and WBEM-Based Hardware Monitoring” (page 7) • “Comparison of Features Provided by WBEM-Based Solution Over EMS & STM based Solution” (page 8) Terminologies Used in EMS & STM based and WBEM-Based Solution This section compares the terminologies used in the EMS & STM based and WBEM-based hardware diagnostics solution.
Figure 1 Architecture of EMS & STM based and WBEM-Based Hardware Monitoring Solution The hardware monitoring process for the EMS & STM based hardware diagnostics solution works in the following way: 1. The EMS Hardware Monitors constantly monitors the health of the server hardware. 2. If the monitor detects an error or an abnormal behavior on the resource it monitors, the monitor generates an event and communicates it to the EMS framework. 3. The EMS framework reports the event to the EMS clients. 4.

2 Migrating from EMS/STM based Solution to WBEM-Based Solution To migrate from the EMS & STM based to the WBEM-based hardware diagnostics solution, use SFM and other WBEM providers. This section includes the following topics: • “Obtaining SFM and WBEM Providers” (page 10) • “Migrating from EMS/STM based to WBEM-Based Solution” (page 10) It also describes the prerequisites for migration.
Starting with the HP-UX 11i v3 February 2007 release, SFM is installed by default on a system running HP-UX 11i v3. SFM is the default monitoring mode on HP-UX 11i v3 operating systems starting with the March 2008 release. This means that the core system hardware such as processors, memory, fan, and power supplies are monitored by the SFM monitors instead of the EMS hardware monitors.
3 Post Migration Activities You can start using SFM without performing any specific tasks or special configuration. However, to take advantage of advance capabilities, which SFM provides, HP recommends few one-time, post migration activities.

Glossary CIM Common Information Model. An object-based model for describing managed resources. CIM uses the object-oriented paradigm, where managed objects are modeled using the concepts of classes and instances. CIMOM Common Information Model Object Manager. The component of WBEM that manages the interaction between the providers and other modules in the WBEM environment. CIMOM manages CIM objects. It receives and processes CIM operation requests and issues responses.
