7.1 Configuring a Physical Partition

7.1 Configuring a Physical Partition
This section provides an overview of physical partition configuration.
To configure a SPARC M12-2S or SPARC M10-4S system, configure a physical partition (PPAR) by combining one or more building blocks in a server of the same model. Configuring physical partitions is called partitioning, and the resulting configured object is called a physical partition (PPAR).
In the SPARC M12-2S/M10-4S, up to 16 physical partitions can be configured.
Note that since the SPARC M12-2/M10-1/M10-4 is a model consisting of a single chassis, it can be configured with only one physical partition.
In the XSCF firmware, when configuring a physical partition, one building block is treated as one system board (PSB).
Generally, there is no problem when the physical partition number for a physical partition being configured matches any of the existing SPARC M12-2S/M10-4S IDs (BB-IDs) in the system.
However, if you anticipate that the system may be reduced after operation starts, you need to consider the appropriate physical partition number for that case when determining the physical partition number. This is because any physical partition with a physical partition number that is the same as the BB-ID of the SPARC M12-2S/M10-4S to be removed must be stopped at the time of reduction.
Before configuring a physical partition, be sure to see "Chapter 4  Configuring a Physical Partition" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide and check the recommended method of configuring a physical partition.
Physical partitions are configured with the setpcl and addboard commands of the XSCF firmware. For details, see "3.1  Operations and Commands Related to Physical Partition Configurations" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 Domain Configuration Guide.
