System Management 4
System Management is an all-encompassing term whose definition can vary drastically depending
on the type of system that is being developed. System Management can indicate anything from
system configuration all the way to active reporting, proactive fault remediation, and
comprehensive system security. In a relatively closed system with limited access to external
interaction, system management could be limited to chassis management, event logging, and
resource management. In systems that require more sophisticated external interface and a finer
granularity of control, system management mechanisms can provide a myriad of APIs and system
services for administering a system.
The intent of this section is to give a developer an overview of what application programming
interfaces are supplied by the High Availability SDK (HASDK).
The HASDK provides System Management capable APIs. The APIs enable Redundant Host
configuration and administration, IPMI infrastructure communication and administration, Hot
Swap device detection and management, Slot Control for control and access of backplane slot
attributes.
Most of the details for creating and administering a Telco based solution are beyond the scope of
this document.
4.1 Redundant Host API
Among these APIs is a PICMG* 2.12 compliant Redundant Host Programming Interface. This
interface allows a client to perform the following operations:
• Initialize and terminate an instance of this interface
• Enumerate the Hosts, domains and slots in the system
• Get information about devices in slots
• Initiate domain switchovers among Hosts
• Enable and disable notifications regarding switchover operations
• Specify actions that result from hardware-initiated alarms and control
See Chapter 6, “Redundant Host API,” for more information.
4.1.1 IPMI API
Platform management is a major component of a comprehensive system management architecture.
Platform management allows for status and event notification of all exposed interfaces such as
temperature sensors, voltage monitors, and other sensory devices. These status and
communications capabilities need to be as extensible as possible.
