EJ,

Just so we are on the same page about this, my understanding is that you 
want only the nodes that have ZERO data (backup, archive, or copy). Under 
normal circumstances, there would be two ways that would happen within 
TSM, if you are running Spectrum Protect (SP)(version 7.1.3 and above) 
there would be three ways, and they are; 
1. The node never performed a backup
2. All of the nodes filespaces have been deleted
3. If node was decommissioned using the SP decommission command

The only time a file within TSM/SP is deleted from the TSM/SP database, is 
if it was modified or deleted, at that time you data retention setting 
kick in. With the SP decommission command, SP marks all of the files as 
inactive thereby applying the assigned data retention setting to all data, 
which would allow for all data to be deleted and once that has completed, 
removes the decommissioned node.

That said, you can try this:

audit lic (ensures that the latest totals are recorded for each node)
select node_name from auditocc where total_mb=0 

That command will validate there is no data (archive, backup, copy) for 
the node

Hi guys!
I'm trying to query the occupancy table to identify nodes with no more 
data store, but I can't find the proper syntax. I thought of this one:
select node_name from occupancy where physical_mb is null
But it returns no nodes, while I know for sure there are several of 
them...
Thanks for any help in advance!
Kind regards,
