NAME setdcl - set a domain component list (DCL)
SYNOPSIS setdcl -d domain_id -s policy=value
setdcl -d domain_id -s option=value lsb [ lsb...]
setdcl -d domain_id -a lsb=xsb [ lsb=xsb...]
setdcl -d domain_id -r lsb [ lsb...]
setdcl -h
DESCRIPTION The setdcl(8) command sets a domain component list (DCL).
A DCL is hardware resource information that can be set for a domain or the logical
system boards (LSBs) that are components of a domain.
An LSB is a board unit recognized by an operating system in a domain. Up to 16
boards can be registered in each domain, and they are represented by integer
numbers ranging from 0 to 15.
An extended system board (XSB) is a board unit that can be used in the system and
is one partition of a partitioned physical system board (PSB). An XSB is represented
by x-y, a combination of a PSB number and the number of one partition of the
partitioned PSB (x is an integer ranging from 00 to 15, and y is an integer ranging
from 0 to 3).
The setdcl(8) command associates an XSB with an LSB that can be recognized by
an operating system in the domain, and its settings enable the operating system in
the domain to use hardware resources on the associated XSB.
The setdcl(8) command can set the following types of DCL information:
For the domain:
■ Degradation range applicable for an error detected during an initial diagnosis of
hardware (policy)
For the LSB:
■ XSB number of the XSB to be associated with an LSB (lsb, xsb)
The XSB with the specified XSB number is associated with an LSB.
■ Using memory mounted on an LSB (no-mem)
The user can specify whether an operating system in the domain can use
memory mounted on an LSB.
■ Using I/O devices mounted on an LSB (no-io)
The user can specify whether an operating system in the domain can use I/O
devices, such as a PCI card, mounted on an LSB.
