Normally, NetBackup will label tapes
as it needs to. If you wish to label tapes to get rid of old headers
or some other reason, utilize multiple ALLOW_MEDIA_OVERWRITE
directives in bp.conf file to overwrite previously used media of a recognized
type
(ANSI, AOS/VS, CPIO, DBR, MTF1, or TAR). Use
the bplabel
command to write a label.
