The XSCF firmware consists of system management applications and two user interfaces to configure and control them:

■XSCF Web, a browser-based graphical user interface

■XSCF Shell, a terminal-based command-line interface

You can access the XSCF firmware by logging in to the XSCF command shell. This document includes instructions for using the XSCF interface as part of the initial system configuration. For more information about the XSCF firmware, refer to Chapter 2 and to the SPARC Enterprise M4000/M5000/M8000/M9000 Servers XSCF User’s Guide.

XSCF firmware, OpenBoot™ PROM firmware, and power-on self-test (POST) firmware are known collectively as the XSCF Control Package (XCP).

XSCF firmware has two networks for internal communication. The Domain to Service Processor Communications Protocol (DSCP) network provides an internal communication link between the Service Processor and the Solaris domains. The Inter-SCF Network (ISN) provides an internal communication link between the two Service Processors in a high-end server.

On a high-end server with two Service Processors, one Service Processor is configured as active and the other is configured as standby. This redundancy of two Service Processors allows them to exchange system management information and, in case of failover, to change roles. All configuration information on the active Service Processor is available to the standby Service Processor.

Solaris OS Software

The Solaris OS is pre-installed at the factory on one domain by default. Within its domain, the Solaris OS includes features to manage Solaris OS system capabilities.

Note – The XSCF firmware requires that all domains have the SUNWsckmr and SUNWsckmu.u packages. Since the Core System, Reduced Network, and Minimal System versions of the Solaris OS do not automatically install these packages, you must do so on any domains that do not already have them.

You can install applications on the domains. That process is managed through the Solaris OS tools. Likewise, any other software management applications that you prefer to use on the domains must be installed through the Solaris OS tools.

The DSCP network provides an internal communication link between the Service Processor and the Solaris domains.
