Name
nodedef - CSM node definition file.
Description
The nodedef (node definition) file is a text file that contains
node attributes that may be used to create CSM node definitions. It is
used as input to the definenode command.
The nodedef file is structured in stanza format, where each stanza
contains information for a unique node. The following rules must be
followed when creating a nodedef file:
- A stanza header consists of the node name followed by a colon
(:).
- Attribute lines must take the form of Attribute=Value.
- A warning message is issued for attributes that are not valid, but the
code continues.
- Each line of the file may have only one header or attribute
definition.
- Only one stanza may exist for each node.
- If the header keyword is default, the attribute values in the
stanza are considered default values for subsequent node definitions.
- Default stanzas may be specified multiple times and at any point in a
definition file. The values apply to all definitions following the
default stanzas in a file. The default values are cumulative. In
other words, a default attribute value will stay set until it is explicitly
unset or changed.
- To turn off a default value, set the attribute to nothing (blank).
- When a specific value for an attribute is provided in the node stanza, it
takes priority over any default value that had been set.
- Comments beginning with the pound sign (#) may be added to the
file. A comment must be on a separate line.
- When parsing the file, tab characters and spaces are ignored.
- By default, some attribute values will be set by the definenode
command when the nodedef file is used as input.
For information about the node definition attributes, see the nodeattributes File.
