Hi Guys,

I'm a networker noob being more familiar with the NetBackup environment.  
I have a question regarding some media management oddities I am seeing.

I have a Scalar 100 Library with 3 LTO-3 drives (400/800GB).  I have 
labled up 20 slots of tapes for this months cycle, lets say for example 
A01-A-20 (parrallelism is set to 12 so all three drives will be utilised 
at once).  

When I first started running the backups, 3 tapes (A01-A03) where mounted 
in the drives and the backups ran fine.  After a few days these tapes 
reached 100% (mode append).  So I therefore assumed (as in netbackup), 
that on the next backup run, the EOT marker would be reached and that 
networker would eject the tapes, mark them as full and import new media 
into the drives. 

This doesn't seem to be the case.  All media in the drives (still A01-A03)
is showing at 100%, all my backup seem to run ok (monitoring shows 
successful backups with fileset information).  But tape usage figures 
shown under Media->Volumes are as follows  
A01 = 805GB, A02 = 735GB, A03 = 1875GB

Clearly something is wrong in my configuration.  A01-A02 look kind of 
right, but A03 is way off.  I would have expected my backups to have 
failed after the last tape reached over 800GB or the media management to 
mount the next available media in the Volume pool.

Any ideas as to what might be happening ?
