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.
