 | |
|        returns the nodeset state for the given nodes. The possible nodeset
 | |
|            states are: netboot, install, boot and discover.
 | |
|     Arguments:
 | |
|         nodes  --- a pointer to an array of nodes
 | |
|         states -- a pointer to a hash table. This hash will be filled by this
 | |
|              function.The key is the nodeset status and the value is a pointer
 | |
|              to an array of nodes.  
 | |
|     Returns:
