Static or Dynamic. A static group is defined to contain a specific set of cluster nodes. A dynamic node group is one that has its members determined by specifying a selection criteria for node attributes.

membergroups
This attribute stores a comma-separated list of nodegroups that this nodegroup refers to. This attribute is only used by PCM.
wherevals
A list of “attr*val” pairs that can be used to determine the members of a dynamic group, the delimiter is “::” and the operator * can be ==, =~, != or !~.
comments
Any user-written notes.
