Hello

 

I have several  Tape Archive Pools defined on TSM.

 

The Archive's tapes are removed periodically from TSM library to a safe.

 

During normal TSM usage there are some Nodes that made archives to those
storage pools.

 

Regarding that some of the tapes are offsite TSM Library, TSM use new
scratch volumes for archive.

 

Now I have several archives tapes with low PCT_UTILIZED how are using
many tapes like the example bellow.

 

Example:

 

VOLUME_NAME  EST_CAPACITY     PCT_UTILIZED     PCT_RECLAIM

Note: Collocation are not used in  Storage Pool

 

My question is: There are any way to configure storage pool to use the
minimal number of tapes (use tape maximum capacity on storage pool)?

 

There are any way to reduce the number of tapes using the maximum tape
capacity or I have to do it manually with command (MOVE DATA)?

 

 

 

Thank you
