We've been on test-mode the past seevral days and we notice 
available_media reports FULL tapes at being filled to no more than 35GB 
capacity even if we don't set the Policies to do compression and the 
backup sets are highly compressible. Netbackup is using the device 
entries in the form of /dev/rmt/c8t0d2BESTnb -- which is the bsd BEST 
density device on HPUX systems... It supposedly offers compression 
laready but an "lssf" or mt stat on the device file does not echo out a 
status that will seem to indicate  has compression... I know that I 
canmanually create a compression device file using "mksf -d stape 
-c....." but isn't Netbackup on HPUX11i  set to automatically confiure 
the best (compression) device entries for the OS?

ANyone running Netbackup 4.5 on HPUX and DLT7000 drives? Please could 
you check what device entries you're using and whether you can go veyond 
the 35GB native capcity?

Thanks!
