=head3 getNodesetStates
|
|
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:
|
|
(return code, error message)
