[D]
degraded
The action to release a unit or function where a failure may have occurred. The action to prevent the failure from affecting the system operation.

The environment where Oracle Solaris configured on the SPARC M12/M10 system can run independently. In the SPARC M12/M10 system, you can configure multiple domains and assign hardware resources to each domain.
[E]
eXtended System Control Facility (XSCF)
The firmware that controls and monitors the SPARC M12/M10.
[F]
fan unit (FANU)
The unit for cooling components inside the chassis of the SPARC M12/M10 system.
field replaceable unit (FRU)
The unit that can be used for replacement, expansion, or reduction of one of the components composing the SPARC M12/M10.
[I]
I/O board
One of the components composing the PCI expansion unit.
[L]
logical system board (LSB)
The board that is associated with a BB in order to be recognized from the domain side when the physical partition (PPAR) is configured. It means a single SPARC M12/M10.
[M]
master XSCF
The XSCF that monitors, manages, and controls the entire system in a building block configuration.
[O]
operation panel (OPNL)
The operation panel installed at the front of the server main unit.
[P]
PCI expansion unit
An optional device for PCIe slot expansion. It is connected by an optical or electrical cable via a link card mounted in the SPARC M12/M10.
physical partition (PPAR)
The unit of physical resources divided by partitioning in a configuration connecting multiple SPARC M12-2S or SPARC M10-4S units in the building block method.
physical partition dynamic reconfiguration (PPAR DR)
The function that enables the addition and deletion of hardware resources (CPU, memory, and I/O) in a physical partition while continuing business on the physical partition.
physical system board (PSB)
The smallest unit of hardware resource for the configuration of a physical partition (PPAR). It means a single SPARC M12/M10.
power distribution unit (PDU)
The unit mounted in the expansion rack to supply power to the crossbar box and SPARC M10-4S.
power supply unit (PSU)
The unit for supplying power to the SPARC M12/M10 system.
power-on self test (POST)
The diagnosis test that is automatically executed when the SPARC M12/M10 is powered on. This test determines whether memory or other hardware has failed.
PPAR configuration list
Information on the hardware resources in each physical partition.
PPAR-ID
The ID used for identifying a physical partition. You can assign up to as many PPAR-IDs as the number of SPARC M12 or SPARC M10 units in a configuration in which multiple SPARC M12-2S units or SPARC M10-4S units are connected in the building block method. For a system in a single-unit configuration, the PPAR-ID is fixed at 0.
- SPARC M12-2S/M10-4S: The PPAR-ID identifies a physical partition in a range of PPAR-ID 0 to 15.
- SPARC M12-1/M12-2/M10-1/M10-4: The PPAR-ID is fixed at 0.
PSU backplane (PSUBP)
The PSU backplane supplies power from the power supply unit to the units composing the SPARC M12/M10.
[R]
RCIL
The interface using IPMI (Intelligent Platform Management Interface) over LAN to implement functions such as power control and network state monitoring.
[S]
service processor
The processor to control and monitor the SPARC M12/M10.
slave XSCF
The state of an XSCF that is neither a master XSCF nor standby XSCF in a building block configuration. A slave XSCF operates in cooperation with the master XSCF, and it monitors, manages, and controls the unit in which it is installed.
SP to SP communication protocol (SSCP)
The protocol for an inter-XSCF network used in a building block configuration.
standby XSCF
The XSCF that operates as the backup to the master XSCF in a building block configuration. If a failure occurs in the master XSCF, the standby XSCF is switched to the master XSCF to continue system control and monitoring.
system control network
The network used for maintenance and management of the SPARC M12/M10. The term is synonymous with "XSCF network."
[T]
takeover IP address
A virtual IP address to be assigned to the master XSCF and standby XSCF in a building block configuration. A virtual IP address allows you to log in to the master XSCF by using an invariable IP address even when the master XSCF and standby XSCF are switched to each other.
[X]
XCP
The package that includes multiple firmware for controlling the SPARC M12/M10. It consists of the following firmware:
- XSCF
- OpenBoot PROM
- Hypervisor
- Power-on self test (POST)
XSCF interface unit (XSCFIFU)
The interface unit that is mounted only in a crossbar box and connects the XSCF of the crossbar box and the one of the SPARC M12-2S/M10-4S.
XSCF network
The network used by the XSCF firmware to manage and monitor the SPARC M12/M10. The term is synonymous with "system control network."
XSCF shell
The command-line interface (CLI) function of the XSCF.
XSCF unit (XSCFU)
The unit where the service processor with the installed XSCF firmware is mounted. The unit is mounted in a crossbar box and the SPARC M12-2/M12-2S. For convenience, a component that has the mounted service processor in the SPARC M12-1/M10-1/M10-4/M10-4S is sometimes called the XSCF unit.
XSCF Web
The browser user interface (BUI) function of the XSCF firmware.
