This chapter introduces Suntrademark Management Center software platform and domain administration on Sun SPARC® Enterprise M4000/M5000/M8000/M9000 servers.

About This Sun Management Center Add-On Software

Sun Management Center software is an open, extensible system-monitoring and
-management application that uses Javatrademark software protocol and Simple Network Management Protocol (SNMP) to provide an integrated and comprehensive enterprise-wide management of Sun products and their subsystems, components, and peripheral devices.

The Sun Management Center User's Guide includes definitions, explanations, and diagrams that clarify the Sun Management Center architecture. Review that document whenever you have questions about how consoles, servers, agents, domains, and modules interact.

The add-on software for Sun SPARC Enterprise Mx000 servers adapts the core Sun Management Center software to function with Sun SPARC Enterprise Mx000 servers.

Sun Management Center 3.6.1 Version 2 add-on software introduces support for the following systems:

This add-on software for Sun SPARC Enterprise Mx000 servers provides the following features:

Sun SPARC Enterprise Mx000 servers are divided into hardware domains, with each domain running a separate instance of the operating system. Depending on the capability and the number of hardware resources, Sun SPARC Enterprise Mx000 servers can support up to 24 domains. (The minimum is one domain.) Because domains are used, the add-on software for Sun SPARC Enterprise Mx000 servers has two modes of operation (FIGURE 1-1):

After the add-on software has been installed on a host machine (workstation or server), you can run Sun Management Center software on that host machine to access the Service Processors in Sun SPARC Enterprise Mx000 servers, as shown in FIGURE 1-2.

To Identify Platforms and Hardware Domains

The platform and hardware domain Details windows are very similar when they are first displayed. By default, both windows open to the Module Browser tab.

Reference: Terms Used in This Document

Note - In this document, administrative domain refers to a Sun Management Center administrative domain, and should not be confused with other uses of the term "domain" related to other Sun products or documentation.

Administrative domain - An administrative domain consists of one or more host systems.

Dynamic reconfiguration - The add-on software for Sun SPARC Enterprise Mx000 servers provides a graphical user interface to facilitate dynamic reconfiguration operations. On the Solaris Operating System, the dynamic reconfiguration feature provides the ability to safely remove compact PCI I/O cards into a system while the operating system is running. On the Service Processor, dynamic reconfiguration provides the ability to reconfigure system resources and safely replace system boards.

Platform - An alternative term for a complete server system. A Sun SPARC Enterprise M5000 server is an example of a platform, as described in this book.

Domain or hardware domain - Within a Sun SPARC Enterprise Mx000 server platform, a domain can consist of a logically independent aggregation of system resources within a partition, with each domain running a separate copy of the operating system. This type of domain consists of system boards and other devices, as opposed to an administrative domain, which can consist of multiple hardware domains and entire platforms. For clarity, this type of domain is referred to as a hardware domain in this book.

Reference: Modules

Hardware configuration information, process monitoring, and management operations for the Sun SPARC Enterprise Mx000 servers are provided by the modules listed in TABLE 1-1:
