I'm in the midst of doing a cleanup job on our TSM servers.  When I do a 'q
license', one of the results is:

Number of Managed System for LAN in use: 107

My question is, what counts as 'in use'?  For example, there are a bunch of
nodes that are defined and are no longer used or associated with any
schedules.  Do these count as 'in use', and if so, should I export the node
out of the db and delete it to get the license counts down?  One other
question: anyone got a query to figure out which nodes are NOT associated
with a schedule.  This would help me identify nodes that are candidates for
export.

Many thanks,
Dylan
