Re: BRMS + ProtecTier

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.
