7.7 Creating a PPAR Configuration List


7.7 Creating a PPAR Configuration List
This section describes how to create a PPAR configuration list.
Note - Generally, there is no problem when the physical partition number for a physical partition being configured matches any of the existing SPARC M12-2S 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 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.
The PPAR configuration list defines the following information required for configuring a physical partition (PPAR):
  1. The number of the physical system board (PSB) of the building block that configures PPAR and the corresponding logical system board (LSB) number
  2. Degradation range (configuration policy)
  3. Hardware resource information
For the SPARC M12-2S, the PPAR configuration list is not set. Set the PPAR configuration list and the configuration policy (which specifies the degradation range for an error detected in an initial diagnosis of hardware).

Use the showpcl command to check the PPAR configuration list, and use the setpcl command to set the list. For an explanation of the setpcl command options, see the setpcl command manual page or the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 XSCF Reference Manual.
With SPARC M12-2S, one SPARC M12-2S unit is treated as one building block (BB). This single building block or the combination of multiple building blocks are used to configure the physical partition (PPAR).
In the building block configuration system, one PPAR or multiple PPARs can be configured. In this case, one building block is treated as a physical system board (PSB) by the firmware. One PPAR is defined by assigning the number of the PSB that shows which building block is used and the number of the corresponding logical system board (LSB).

  1. Execute the showpcl command to check the PPAR configuration list.
    The factory default settings do not have a set PPAR configuration list.
XSCF> showpcl -p 0
PPAR-ID    LSB    PSB   Status
  1. Execute the setpcl command to create a PPAR configuration list.
  1. The following example maps the BB-ID (PSB 00-0) to LSB 0 of physical partition 0 (PPAR-ID 0).
XSCF> setpcl -p 0 -a 0=00-0
  1. The following example maps BB#01 (PSB 01-0), BB#02 (PSB 02-0), and BB#03 (PSB 03-0) to LSB 0, LSB 1, and LSB 2 of physical partition 1 (PPAR-ID 1), respectively.
XSCF> setpcl -p 1 -a 0=01-0 1=02-0 2=03-0
  1. Execute the setpcl command to set the configuration policy for all physical partitions as a whole.
XSCF> setpcl -p ppar_id -s policy=value
  1. For value, specify fru (a part, such as a CPU or memory), BB (physical system board (PSB)), or system (all physical partitions as a whole) as the degradation unit. The default setting is fru.

    The following example sets the configuration policy to "All physical partitions" for physical partitions 0 and 1.
XSCF> setpcl -p 0 -s policy=system
XSCF> setpcl -p 1 -s policy=system
  1. Execute the showpcl command to check the PPAR configuration list that has been set.
    The following example assumes the 1BB configuration with the SPARC M12-2S.
XSCF> showpcl -a -v
