Domain Configuration Terms (Continued)
TABLE 2-19
Term Description
Floating board A floating board is designated to be moved easily to another domain. In operation with a
(Note) kernel and important I/O on the system board in a domain, and to facilitate the DR
operation of the system board, it is necessary to define the system board so that can be
deleted or moved easily.
This definition is called a floating board option. A system board that lowered priority of
the kernel memory loading by enabling the floating board option is called a floating
board.
XSB status The power status and the diagnostic, assignment, and integration conditions of a system
board belonging to a domain are displayed for each XSB. The progress of changes in
conditions can be found by switching the domain configuration. The XSB status
information can be referred to with showdcl (8) and showboards (8). For details on the
XSB status, see
Fault code Indicating that an error occurred in an XSB. For details on the fault codes, see
System board pool The state of system board that does not belong to any domain. A system board that is the
system board pool state can be added to a domain where a CPU or memory has a high
(SP)
load. When the added system board becomes unnecessary, the system board can be
returned to the system board pool state.
Note – DR: Abbreviation for Dynamic Reconfiguration. This function dynamically
adds a system board to a domain or deletes it from a domain. For details on DR, see
the Dynamic Reconfiguration User's Guide.
Note – Specified or displayed by the DCL. When the system board uses kernel or
I/O, for details of the DR operation and notation, see the Dynamic Reconfiguration
User's Guide.
Note – For details of components such as CMU, I/O unit, and Motherboard unit,
see the Service Manual for your server.
