124 IBM Power System S822 Technical Overview and Introduction
4.3.4 Notifying
After a Power Systems server detects, diagnoses, and reports an error to an appropriate
aggregation point, it then takes steps to notify the client, and if necessary the IBM support
organization. Depending on the assessed severity of the error and support agreement, this
client notification might range from a simple notification to having field service personnel
automatically dispatched to the client site with the correct replacement part.
Client Notify
When an event is important enough to report, but does not indicate the need for a repair
action or the need to call home to IBM service and support, it is classified as
Client Notify.
Clients are notified because these events might be of interest to an administrator. The event
might be a symptom of an expected systemic change, such as a network reconfiguration or
failover testing of redundant power or cooling systems. These events include the following
examples:
Network events such as the loss of contact over a local area network (LAN)
Environmental events such as ambient temperature warnings
Events that need further examination by the client (although these events do not
necessarily require a part replacement or repair action)
Client Notify events are serviceable events, by definition, because they indicate that
something happened that requires client awareness if the client wants to take further action.
These events can always be reported back to IBM at the discretion of the client.
Call home
Call home refers to an automatic or manual call from a customer location to an IBM support
structure with error log data, server status, or other service-related information. The call home
feature invokes the service organization so that the appropriate service action can begin. Call
home can be done through HMC or most non-HMC managed systems. Although configuring
a call home function is optional, clients are encouraged to implement this feature to obtain
service enhancements such as reduced problem determination and faster and potentially
more accurate transmittal of error information. In general, using the call home feature can
result in increased system availability. The Electronic Service Agent application can be
configured for automated call home. See 4.4.4, “Electronic Services and Electronic Service
Agent” on page 135 for specific details.
Vital product data 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 the representatives to provide assistance in keeping
the firmware and software current on the server.
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.
