       property_attributes - resource property attributes

       The  list below describes the resource property attributes that you can use to change sys-
       tem-defined properties or create extension properties.

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


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


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


	   Indicates a default value for the property.


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


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


	   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.


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


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


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


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


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

	   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.


	   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.


	   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).

       Example 1 An Int Type Definition

       An Int type definition might look like this:

		 Property = Probe_timeout;
		 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;
		 Enum { Off, Terse, Verbose };
		 Default = Terse;
		 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.
