conditions, forwards them to the Service Focal Point application, and notifies the system
administrator.
After the information is logged in the Service Focal Point application, if the system is correctly
configured, a Call Home service request is initiated and the pertinent failure data with service
parts information and part locations is sent to the IBM service organization. This information
also contains the client contact information as defined in the IBM Electronic Service Agent
(ESA) guided setup wizard. With the new HMC V8R8.1.0, a Serviceable Event Manager is
available to block problems from being automatically transferred to IBM. For more information,
see “Service Event Manager” on page 135.
Error logging and analysis
When the root cause of an error is identified by a fault isolation component, an error log entry
is created with basic data, such as the following examples:
򐂰 An error code that uniquely describes the error event
򐂰 The location of the failing component
򐂰 The part number of the component to be replaced, including pertinent data such as
engineering and manufacturing levels
򐂰 Return codes
򐂰
Resource identifiers
򐂰 FFDC data
Data that contains information about the effect that the repair has on the system is also
included. Error log routines in the operating system and FSP can then use this information
and decide whether the fault is a Call Home candidate. If the fault requires support
intervention, a call is placed with service and support, and a notification is sent to the contact
that is defined in the ESA-guided setup wizard.
Remote support
The Remote Monitoring and Control (RMC) subsystem is delivered as part of the base
operating system, including the operating system that runs on the HMC. RMC provides a
secure transport mechanism across the LAN interface between the operating system and the
optional HMC. It is used by the operating system diagnostic application for transmitting error
information. It also performs several other functions, but they are not used for the service
infrastructure.
Service Focal Point application for partitioned systems
A critical requirement in a logically partitioned environment is to ensure that errors are not lost
before being reported for service. In addition, each error should be reported only once,
regardless of how many logical partitions experience the effect of the error. The Service Focal
Point application on the management console or in the IVM is responsible for aggregating
duplicate error reports, and ensures that all errors are recorded for review and management.
The Service Focal Point application provides other service-related functions, such as
controlling service indicators, setting up Call Home, and providing guided maintenance.
When a local or globally reported service request is made to the operating system, the
operating system diagnostic subsystem uses the RMC subsystem to relay error information to
the optional HMC. For global events (platform unrecoverable errors, for example), the service
processor also forwards error notification of these events to the HMC, providing a redundant
error-reporting path in case of errors in the RMC subsystem network.
