NAME

nodegroup - a table in the xCAT database.

SYNOPSIS

nodegroup Attributes: groupname, grouptype, members, membergroups, wherevals, comments, disable

DESCRIPTION

Contains group definitions, whose membership is dynamic depending on characteristics of the node.

nodegroup Attributes:

groupname

Name of the group.

grouptype

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.

members

The value of the attribute is not used, but the attribute is necessary as a place holder for the object def commands. (The membership for static groups is stored in the nodelist table.)

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.

disable

Set to ‘yes’ or ‘1’ to comment out this row.
