1.3.2 Working With a Physical Partition Configuration


1.3.2 Working With a Physical Partition Configuration
This section describes how to work with a physical partition configuration with multiple SPARC M12-2S or M10-4S units.
To set the physical partition configuration and work with physical partitions, use the XSCF shell and XSCF Web provided by the XSCF. Operations through them are collectively managed by the XSCF. In addition, XSCF security management allows only administrators with specific access privileges to perform operations related to a physical partition configuration. For details on the XSCF shell commands for physical partition configurations, see "3.1 Operations and Commands Related to Physical Partition Configurations."
For XSCF Web operations, see "Chapter 3 Configuring the System" in the Fujitsu SPARC M12 and Fujitsu M10/SPARC M10 System Operation and Administration Guide.
Registering/Releasing a system board
"Registering a system board" means providing a physical system board (PSB) that indicates one building block (BB) with a logical system board number (LSB number) and setting it in the physical partition configuration information.
"Releasing a system board" means deleting a PSB (BB) from the physical partition configuration information. The registration of a physical system board (PSB) in physical partition configuration information enables you to perform PSB (BB) operations, such as assigning and incorporating the PSB (BB) into the physical partition.
Adding a system board
"Adding a system board" means incorporating an installed building block (PSB) or unused PSB (BB) that does not belong to any physical partition, into a physical partition. The process of adding a PSB (BB) is performed step-by-step, first with "connect" and then "configure." When you add a PSB (BB), the specified PSB (BB) first connects to the relevant physical partition. That is followed by the process of incorporating the PSB (BB). The addition of the PSB (BB) is completed at this point.
Deleting a system board
"Deleting a system board" means releasing a building block (PSB) that is no longer necessary from the physical partition to be configured. The process of deleting a PSB (BB) is performed step-by-step, first with "unconfigure" and then "disconnect."

To assign the PSB (BB) to a different physical partition, you need to include the unassign operation in the deletion process. When you delete a PSB (BB), the specified PSB (BB) is first released. Then, it is disconnected from the physical partition to which it belongs. The deletion of the PSB (BB) is completed at this time.
Assigning/Unassigning a system board
"Assigning a system board" means assigning an installed building block (PSB) or an unused PSB (BB) that does not belong to any physical partition so that it belongs to a physical partition. "Unassigning a system board" means releasing a building block or PSB from the physical partition to which it belongs.

Assigning a PSB (BB) to the relevant physical partition disables operation of the PSB (BB) from a different physical partition. When you assign a PSB (BB) to a physical partition and power on the physical partition, the PSB (BB) is added. When you power off the physical partition, the PSB (BB) is deleted and assigned to the physical partition.

When you unassign an assigned system board from its physical partition, it no longer belongs to any physical partition and can be assigned to a different physical partition.
Replacing a system board
"Replacing a system board" means replacing a building block (PSB) for maintenance purposes. You can use this operation when replacing CPU, memory, and I/O device hardware resources. The process of replacing a PSB (BB) is performed step-by-step. When you replace a PSB (BB), the specified PSB (BB) is deleted. Once the deletion of the PSB (BB) is completed, the PSB (BB) is ready to be removed. Remove the PSB (BB) at this point. Then, after performing work such as component replacement, re-install the new PSB (BB) for the replacement. After that, once the installation is completed, the addition of the PSB (BB) completes the replacement.
System board pool function
The system board pool function is a function that puts a specific system board (PSB<BB>) into a state where it does not belong to any physical partition. This function is effective for moving a PSB (BB) among multiple physical partitions as required. For example, you can take a PSB (BB) from the system board pool and then add it to a physical partition that is subject to high CPU and memory loads. You can also return a system board to the system board pool when it is no longer needed.
You can assign a pooled PSB (BB) to a physical partition only if it is registered in physical partition configuration information (PPAR configuration information). In other words, by registering the same PSB (BB) in the configuration information for multiple PPARs, you can flexibly operate the system by incorporating or releasing the PSB (BB) according to the operating status of physical partitions. However the usage of pooled PSB (BB) must be properly managed for such operations.
You can also combine this function with the memory nullification option and I/O nullification option described in "2.2 XSCF Conditions and Settings" to easily add and delete PSBs (BBs).
Reserving a physical partition configuration change
You not only can dynamically add or delete a system board (PSB<BB>) in a physical partition but also can reserve the reconfiguration performed at the next power on/off or restart time of that physical partition.
For example, you can reserve a physical partition configuration change for the following occasions.
  1. When dynamic reconfiguration cannot reconfigure hardware resources for business and operational convenience.
  2. When you do not want to immediately change the physical partition configuration.
  3. When you want to prevent dynamic reconfiguration operations from changing settings and want to change the configuration immediately after a physical partition restart: An example is when you are deleting a PSB (BB) that has a driver or PCI card that does not support dynamic reconfiguration.
Table 1-1 lists the operations available on the system boards (PSB<BB>) composing a physical partition.

Term Description
Register To register a system board in physical partition configuration information
Release To release the registration of a system board from physical partition configuration information
