Chapter 4. Continuous availability and manageability 177
Client Notify events are serviceable events, by definition, because they indicate that
something has happened that requires client awareness in the event that the client
wants to take further action. These events can always be reported back to IBM at the
client’s discretion.
Call home
A correctly configured POWER processor-based system can initiate an automatic or manual
call from a client location to the IBM service and support organization with error data, server
status, or other service-related information. The call-home feature invokes the service
organization in order for the appropriate service action to begin, automatically opening a
problem report and, in certain cases, also dispatching field support. This automated reporting
provides faster and potentially more accurate transmittal of error information. Although
configuring call-home is optional, clients are strongly encouraged to configure this feature to
obtain the full value of IBM service enhancements.
Vital product data (VPD) and inventory management
Power Systems store vital product data (VPD) internally, which keeps a record of how much
memory is installed, how many processors are installed, the manufacturing level of the parts,
and so on. These records provide valuable information that can be used by remote support
and service representatives, enabling them to provide assistance in keeping the firmware and
software on the server up-to-date.
IBM problem management database
At the IBM support center, historical problem data is entered into the IBM Service and
Support Problem Management database. All of the information that is related to the error,
along with any service actions taken by the service representative, is recorded for problem
management by the support and development organizations. The problem is then tracked
and monitored until the system fault is repaired.
4.3.5 Locating and servicing
The final component of a comprehensive design for serviceability is the ability to effectively
locate and replace parts requiring service. POWER processor-based systems use a
combination of visual cues and guided maintenance procedures to ensure that the identified
part is replaced correctly, every time.
Packaging for service
The following service enhancements are included in the physical packaging of the systems to
facilitate service:
򐂰 Color coding (touch points)
– Terra-cotta-colored touch points indicate that a component (FRU or CRU) can be
concurrently maintained.
– Blue-colored touch points delineate components that are not concurrently maintained
(those that require the system to be turned off for removal or repair).
򐂰 Tool-less design: Selected IBM systems support tool-less or simple tool designs. These
designs require no tools or simple tools, such as flathead screw drivers to service the
hardware components.
򐂰 Positive retention: Positive retention mechanisms help to ensure proper connections
between hardware components, such as from cables to connectors, and between two
cards that attach to each other. Without positive retention, hardware components run the
risk of becoming loose during shipping or installation, preventing a good electrical
