Re: Moving from 1 large tape pool to multiple tape pools

[Ray Baughman]

Bruce,

select distinct node_name from contents where volume_name = 'volumename'
will tell the nodes on a tape.  If you move the data on the volume, it will
separate the nodes, if collocation is on.  If the volume has multiple nodes
on it, just do a move data to the same storage pool.

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,
