Holger;

In a BRMS environment you would only initialize a tape or tape image exactly one time, when you first add it to BRMS. To re-initialize it will destroy quite a bit of information that is very useful. BRMS does not automatically initialize a tape since it uses expiration dates to the utmost, it will automatically expire a tape and files on the tape as appropriate when BRMS maintenance is run.

Most of the virtual tape libraries I know allocate the space for a tape image and then leave that space allocated even after the tape is expired since that is the space that would be potentially used on another backup operation. Does the ProtecTier not have a management screen that shows you it's status? (I have not worked with one) Every other VTL I do work with does, and I think that's the number that really matters. In the SPHiNX (Crossroads) the storage status is easy to view, each tape and the space it uses is clearly laid out. I have to believe there is a similar display for the ProtecTier system.

Hello all,

i am sitting at a customers running a P750 with BRMS and saving
to a VTL (IBM ProtecTier). Working perfectly, but we have the
question of how good is the capacity display on the ProtecTier.
For example we have media in BRMS which are set to *EXP,
but the ProtecTier shows them as active (it does not know
about the *EXP state). We want to know how much data is
really "active", and how to set the media in the VTL to
"expired". At this time we are going to do an INZTAP on
the media, which should be done automatically by BRMS.

Does anyone has a good idea on that question?

Thanks,
Holger
