Once device files have been created, you should confirm that your new tape drive is working
properly. Chapter 8 on page 37 provides instructions on backing up and restoring a sample file to
test your installation.
Device filenames under AIX
Use device filenames as listed below for the combination of Rewind on Close, Retension on Open,
and Compression that you want:
The
n
in the filename is the instance number assigned to the drive by the operating system, where 0
is the first device, 1 is the second and so on.

Rewind on Close Normally, the drive repositions the tape to BOT (Beginning of Tape) when the
device file is closed. Using the no rewind option is useful when creating and
reading tapes that contain multiple files.
Retension on Open Retensioning consists of winding to EOT (End of Tape) and then rewinding to
BOT, in order to reduce errors. If this option is selected, the tape is positioned
at BOT as part of the open process.
Compression Compression can be disabled or enabled.
