About removing tape files
When you have completed reading or writing tape files, use the /usr/openv/volmgr/bin/tpunmount command to end the assignment of the tape file. This command removes from the directory the tape file you created by with tpreq and removes the tape volume from the tape drive. The tpunmount command is required for each file that the tpreq command creates.

On UNIX, the NetBackup tpunmount command runs the drive_unmount_notify script (if it exists) after media is unmounted.
