Predefined Attribute Extended (PdAtXtd) Object Class

The Predefined Attribute Extended (PdAtXtd) object class is used to supplement existing device attributes that are represented in the Predefined Attribute (PdAt) object class with information that can be used by Device Management User Interface.

Types of attributes to represent in PdAtXtd

Not all existing device attributes in PdAt must be represented in the PdAtXtd object class. Non-displayable attributes (that is, attributes with a null string in the 'generic' field of the PdAt object class) must not have a corresponding PdAtXtd entry, otherwise, it becomes displayable.

The PdAtXtd object class can also be used to override the current value or possible values of an attribute.

Predefined Attribute Extended Object Class Descriptors

The Predefined Attribute Extended object class contains the following descriptors:

ODM Type	Descriptor Name	Description	Required
ODM_CHAR	uniquetype	Unique Type	Yes
ODM_CHAR	attribute	Attribute Name	No
ODM_CHAR	classification	Attribute Classification	No
ODM_CHAR	sequence	Sequence number	No
ODM_VCHAR	operation	Operation Name	No
ODM_VCHAR	operation_value	Operation Value	No
ODM_VCHAR	description	Attribute Description	No
ODM_VCHAR	list_cmd	Command to list Attribute value	No
ODM_VCHAR	list_values_cmd	Command to list Attribute values	No
ODM_VCHAR	change_cmd	Command to change Attribute value	No
ODM_VCHAR	help	Help text	NO
ODM_VCHAR	nls_values	Translated Attribute values	No

These descriptors are described as follows:

Descriptor	Description
uniquetype	Identifies the class-subclass-type name of the device to which this attribute is associated. This descriptor is the same as the Unique Type descriptor in the PdAt object class.
attribute	Identifies the device attribute. This name can be passed to mkdev and chdev configuration commands and device methods in the attribute-name and attribute-value pairs.
classification	Identifies the classification of the device attribute. The followings characters are valid values: B Indicates a basic attribute. A Indicates an advanced attribute. R Indicates a required attribute.
sequence	Identifies the number that is used to position the attribute in relation to others on a panel or menu. This field is identical to the `id_seq_num` currently in the `sm_cmd_opt` (SMIT Dialog/Selector Command Option) object class.
operation	Identifies the type of operation that is associated with the unique device type. Operation and attribute name fields are mutually exclusive.
operation_value	Identifies the value that is associated with the `Operation` field. When the operation is `add_device`, the `operation_value` field can contain the command that is used to make the device, if the mkdev command cannot be used.
description	Identifies the attribute description.
list_cmd	Identifies the command to override the current value of the attribute, except when the operation field is set. If the operation field is set, it identifies the command to return information that is associated with the operation. For example, in the case of the `add_tty`operation, the `list_cmd` field contains the following value: `lsdev -P -c tty -s rs232 -Fdescription`
list_values_cmd	Identifies the command to obtain the possible values of an attribute. The values that are returned override the values field in the Predefined Attribute object class.
change_cmd	Identifies the command to change the attribute value if the chdevcommand cannot be used.
help	Identifies the help text that is associated with the attribute. The help text format follows: `message file,set id,msg id,default text` OR `a numeric string equal to a SMIT identifier tag.`
nls_values	Identifies the text that is associated with the attribute values. These values are displayed in place of the values that are stored in the Predefined Attribute object class. This field must be of the following form: `message file,set id,msg id,default text` The ordering of values must match the ordering in the Predefined Attribute values field.
