NAME
       property_attributes - resource property attributes

DESCRIPTION
       The  list below describes the resource property attributes that you can use to change system-defined properties or create extension proper-
       ties.

       You cannot specify NULL or the empty string ("") as the default value for Boolean, Enum, or Int types.

       Array_maxsize

	   For Stringarray type, the maximum number of array elements permitted.

       Array_minsize

	   For Stringarray type, the minimum number of array elements that is permitted.

       Default

	   Indicates a default value for the property.

       Description

	   A string annotation intended to be a brief description of the property. The description attribute cannot be set in  the  RTR  file  for
	   system-defined properties.

       Enumlist

	   For an Enum type, a set of string values permitted for the property.

       Extension

	   If  used,  indicates that the RTR file entry declares an extension property defined by the resource type implementation. Otherwise, the
	   entry is a system-defined property.

       Max

	   For an Int type, the maximum value permitted for the property. Note that you cannot specify a maximum value for a method timeout.

       Maxlength

	   For String and Stringarray types, the maximum string length that is permitted.

       Min

	   For an Int type, the minimal value permitted for the property. Note that you cannot specify Min=0 for a method timeout.

       Minlength

	   For String and Stringarray types, the minimum string length permitted.

       Per_node

	   If used, indicates that the extension property can be set on a per-node or a per-zone basis.

	   If you specify the Per_node property attribute in a type definition, you must  specify  a  default  value  with  the  Default  property
	   attribute  as  well.  Specifying  a default value ensures that a value is returned when a user requests a per-node or per-zone property
	   value on a node or zone to which an explicit value has not been assigned.

       Property

	   The name of the resource property.

       Property Type

	   Allowed types are: String, Boolean, Int, Enum, and Stringarray. You cannot set the type attribute in an  RTR  file  entry  for  system-
	   defined  properties.  The  type determines acceptable property values and the type-specific attributes that are allowed in the RTR file
	   entry. An Enum type is a set of string values.

       Tunable

	   Indicates when the cluster administrator can set the value of this property in a resource. Can be set to None or False to  prevent  the
	   administrator  from	setting the property. Values that allow administrator tuning are: True or Anytime (at any time), At_creation (only
	   when the resource is created), or When_disabled (when the resource is offline).

	   The default is True (Anytime).

EXAMPLES
       Example 1 An Int Type Definition

       An Int type definition might look like this:

	 {
		 Property = Probe_timeout;
		 Extension;
		 Int;
		 Default = 30;
		 Tunable = Anytime;
		 Description = "Time out value for the probe (seconds)";
	 }

       Example 2 A Per_node Type Definition

       A Per_node type definition might look like this:

	 {
		 Property = LogLevel;
		 Extension;
		 Enum { Off, Terse, Verbose };
		 Default = Terse;
		 Per_node;
		 Tunable = At_creation;
		 Description ="Controls the level of detail for logging";
	 }

       If you specify the PER_NODE property attribute in a type definition, you must specify a default value with the DEFAULT  property  attribute
       as well.
