CHAPTER 1 RCI Overview
RCI redundancy (only for the high-end system)
The eXtended System Control Facility (XSCF) unit (Note) of the high-end system has
a redundant configuration (duplicated configuration), realizing a high-reliability
system. The redundant configuration of the XSCF unit can duplicate a network (RCI
network) created by connecting RCI units with RCI cables.
Note: The XSCF has a system control facility that runs on a service processor
provided as standard in the base cabinet. A board with a preinstalled XSCF
control program (XSCF firmware) is an XSCF unit.
1.2 RCI Functions
This section describes the functions provided by the RCI.
RCI network status monitoring
For stable operation of an RCI network, an RCI host constantly monitors the status of
the RCI network. Upon detection of a failure in the RCI network, the RCI host
collects a hardware log and reports the failure to the relevant domain.
Control of power supply to RCI I/O units
When an RCI host is powered on or off, the RCI host powers on or off, respectively,
RCI I/O units synchronously. When at least one RCI host in an RCI network is
powered on, all RCI I/O units are powered on synchronously. When all RCI hosts are
powered off, all RCI I/O units are powered off synchronously.
Interlocking mechanism for power supply to domains
When remote power control mode is set for a domain, the domain is powered on and
off in synchronization with other domains in the RCI network.
To set remote power control mode in a domain, execute the setpwrmode command in
the domain.

Administration.
