Domain Component
List (DCL)
This is a list of domain configuration information. The DCL represents the hardware
resource information that is set for each domain and each LSB belonging to a domain. It
can be specified and displayed by
setdcl
(8) and
showdcl
(8), respectively.
Memory mirror
mode
In this mode, a PSB has two memory units, one mirroring the other. Saving the same data
in the separate memory units improves data security.
DIMM (Memory)
Memory modules on a system board. For details on DIMMs, see the
Service Manual
for
your server.
Configuration
policy (Note 2)
If an error is detected in a domain in an initial hardware diagnosis, the range of logical
resources to be removed can be specified. The policy determines whether to remove
system boards or separate resources. On M3000 servers, the
setdcl
(8) command can only
be used to set configuration policy.
Omit-I/O option
(Note 2)
System board (XSB) configuration that prevents a specific domain from logically using
I/O units on a system board. The DR function (Note 1) is enabled with fewer hardware
resources.
(A PCI and LAN driver are prevented from being incorporated into the domain of an
LSB.)
Omit-memory
option
(Note 2)
System board (XSB) configuration that prevents a specific domain from logically using
memory on a system board.
Floating board
(Note 2)
A floating board is designated to be moved easily to another domain. In operation with a
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
TABLE 2-23
.
Fault code
Indicating that an error occurred in an XSB. For details on the fault codes, see
TABLE 2-23
.
System board pool
(SP)
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
load. When the added system board becomes unnecessary, the system board can be
returned to the system board pool state.
