Another approach is:
select node_name from volumeusage where stgpool_name='________'
to verify if the nodes you expect are actually participating in a
group-collocated storage pool.
Notes:
- Nodes may participate in a group-collocated storage pool and
not be defined in a collocation group, such that collocation by
node would then be in effect for such clients, and make for more
tape use than you might expect.
- The VOLUMEUSAGE table is expensive to search, so do only when
necessary.
