Uni-XSB One of the division types for a PSB to be configured. Uni-XSB is a name for when a PSB is
logically only one unit (undivided status). It is a default value setting for the division type
for a PSB. The division type can be changed by using the XSCF command
<setupfru(8)>. Uni-XSB may be used to describe a PSB division type or status.
Quad-XSB One of the division types for a PSB to be configured. Quad-XSB is a name for when a PSB
is logically divided into four parts. The division type can be changed by using the XSCF
command <setupfru(8)>. Quad-XSB may be used to describe a PSB division type or
status.
Hardware resource Hardware components contained on a system board that configures a domain.
Domain
Configuration Divides hardware resources in this system into independent software-based units.
Partitioning is performed with XSCF as follows:
1. XSBs are defined with each consisting of a CMU or MBU and an I/O unit divided by
software. (In midrange servers, there will be I/O on only half of the XSBs.)
2. Each XSB is handled as a logical system board (LSB) so that it can configure a domain
and be assigned a number (LSB number). Furthermore, XSCF can define LSB resources in
detail.
3. The domain operates with the LSB resources and the LSB number.
Domain ID (DID) ID assigned to a domain.
DCL Abbreviation for Domain Component List. 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 physical system board (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) 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.
Omit-I/O option
(Note) System board (XSB) configuration that prevents a specific domain from logically using
I/O units on a system board. The DR function 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) System board (XSB) configuration that prevents a specific domain from logically using
memory on a system board.
