Hello, Mehdi. I hope this answer isn't too late for you.
In the TS7650[G], a virtual cartridge is not erased the volume is
written to from the beginning - i.e. a "label libvol" is performed on
it. Before the RELABELSCRATCH function was added to TSM, data on a
virtual volume would be accessible until the volume was reused, even if
it was returned to scratch 3 years ago and has been unused since.
Nowadays, if you use the RELABELSCRATCH feature, that data will be
accessible only until REUSEDELAY expires, whereupon the volume is
returned to scratch and relabeled, and the data erased.
The remote site will erase that same volume when the asynchronous
replication "catches up" to the relabeling.
A few things to keep in mind:
- For TSM to be able to find that data after expiration, TSM will have
to have its database restored to a point in time in which that data
still exists.
- Even if a file is expired, the volume it resides on is not reclaimed
until it falls below the RECLAIM of the stgpool. This means the volume
may not be reclaimed for quite a while after the expiration of the file
in which you are interested.

Hi,
A VTL in primary site copies backup data to remote site asynchronously.
If
some backups expire in TSM, what happens to the copy in remote site?
Will it
be expired or retained?
Thanks
