Hello all,
I want to separate my tape pool into tape pools for each OS (ie AIX, NT/200,
Netware....)  I turned on collocation about 6 months ago.
1)  How can I find out which tapes are fully collocated & which tapes have
multiple node backups on them.

This can be done by running a query against the database. Something like:
select volume_name,node_name from volumeusage where volume_name='$1' group by 
volume_name,node_name



2)  If a tape has multiple nodes on them (same OS) & I do a MOVEDATA to the
new tape pool will the movedata command put each node to a
separate tape?

Provided collocation is turned and you have enough tapes available.

3)  If a tape contains multiple nodes (different OS's) how do I move this
data to new storage pools?

I don't know of an easy way. What I did was a move to a disk pool, and then 
migrate back to a tape pool with collocate, and then move the separate vols. to 
the pools you want them in. Rather tedious, but it worked.

Thanks,
