7.1.3 Error handling

Detection of certain CEC hardware failures will cause the primary service
processor to terminate the IPL. After the IPL has been terminated the primary
service processor will initiate a failover to the back-up service processor (when
supporting firmware is available and installed).
In the case that a system dump is performed, this will occur on the primary
service processor detecting the CEC hardware failure. If the dump has not been
extracted prior to the failover, then the CEC hardware data must be shadowed to
the new primary. The CEC hardware data and main store memory would then be
extracted from this new primary.
From the HMC a user can open an Advanced System Management (ASMI)
browser session to view error log information and access the service processor.
ASMI menus are accessible as long as there is the power applied to the frame.
ASMI sessions can also be opened while partitions are running. It is possible to
connect to the service processor using a personal computer as long as the
system is connected to the service processor network. The IBM Sserver
Hardware Information Center has a section on accessing the Advanced System
Management Interface.

7.2 Service processor cabling

There are five ports on the service processor card used for power (SPCN), light
strip connectors, t bulk power controller (BPC) connectors and one unused
connection (J05). Figure 7-1 provides a front view of the service processor card
connections. The service processor cable connections are summarized in
Table 7-1 on page 173.
