SCF Objects
For more specific information about useful SCF commands, refer to Section 2, Using
SCF to Display Your System’s Configuration.
SCF Objects
The individual subsystem components are called objects. Each object has an object
type and an object name. The object type describes the type of the object, such as SU
(subdevice), DISK, or PROCESS. The object name uniquely identifies an object within
the system.
Object names usually follow a consistent set of naming conventions. SCF objects are
usually referred to by their device names, which consist of a dollar sign ($) followed by
a letter and several alphanumeric characters. The number of characters is determined
by the subsystem. A LINE object, for example, might have the name $LIN32. A
PROCESS object sometimes has the same name as the line it controls. For detailed
information about objects, refer to SCF Objects on page 5-2.
There are many other object types and object names used in SCF. The objects
relevant to each subsystem are described in the SCF reference manual relating to that
subsystem.
SCF Subdevices
The object name for a subdevice usually has two parts: the name of the object to
which a subdevice has been added and the unique name of the subdevice itself. The
subdevice part of the name begins with a pound sign (#) and includes several
alphanumeric characters. The number of characters is determined by the subsystem.
For example, a subdevice might have the name $LIN32.#PC, where $LIN32 is the
name of the line.
Some subsystems are structured hierarchically, with a group of objects of one type
logically subordinate to an object of another type. For example, if a number of
subdevices are configured on a single line, an object specification (
object-spec
) of
the form $
line-name.*
(as in $LINE1.*) can be used to refer to all subdevices on
that line.
Other subsystems use the SUB parameter of some SCF commands to refer to all
subordinate objects. The SUB parameter has the form
SUB [
subobjtype
]
This parameter selects the subordinate objects the command affects. The
subobjtype
variable can be a subordinate object type or one of the keywords ONLY,
ALL, or NONE:
•
If a subordinate object type is named, only objects of that type are affected. If
subobjtype
is omitted, ALL is assumed.
•
ONLY specifies that only the subordinate objects are affected.
