Hello Jim,

yes, ProtecTier shows about state only "active" and "read/write",
as it doesn't know about expiration state from BRMS.

IT management here wants to know the real used "active" data space,
thus when a tape goes to "expired" they argue that the space on
the VTL should be freed - my only idea about this is to init the
tape as then the allocated spaces is set back to 0MB...

This depends on backup strategy here which should be revised in my opinion.
At this moment they use retention time of 35 - 56 days, depending of
LPAR, and do a full save every night. The VTL has some more media for
each LPAR for test saves etc. In my opinion the lose time struggling
around with that question - but they want to know of the used storage
on the VTL will be enough in the next months / years or if the
amount is rising for any reason.

In my thoughts - it is a theoretical discussion :)

thanks for your input,

In a BRMS environment you would only initialize a tape or tape image exactly one time, when you first add it to BRMS. ...
