A good place to start is to look at our recommended settings for st.conf.
You can find that in a file I think called dev_config_guide.txt in
/usr/openv/netbackup.  Those settings are not "set" in stone mind you.  If
you have particular needs than read the man page on st to see what you might
want to change.  The most important for netbackup is that you have variable
block mode set which is the third setting a plain 'ol 0.  As for reusing DLT
tapes written by DLT4000 drives that's fine but sometimes you'll see a "not
enough space" error message the tape is scanned or written to.

Subject: [Veritas-bu] DLT 4000 to DLT 7000 conversion


We are using NetBackup 3.2 on a SUN4000 (Solaris 2.6) and using two STK
9710 silos with 10 DLT 4000 each. Our plan is to upgrade the tape drives
to DLT 7000s. The questions are:

  1. Will NetBackup be able to read existing backup tapes ( the DLT IV 
      carts are used )

  2. After the upgrade will the tapes be written in DLT7000 mode or
must      the tapes be blank labeled 

  3. I have seen several different DLT7000 definitions for the st.conf
      file .... what is correct


Thanks for the help,

Paul
