Load the data cassette into the tape drive. 3. In a terminal window, enter the following command line to write to the tape: tar -cvf /dev/rmt/〈devicefile〉 〈pathname〉 where 〈devicefile〉 is one of the device files listed from ioscan and 〈pathname〉 is the pathname of the file or directory containing files that you want to write to the tape. To use the data-compression mode, use one of the device file names that sam listed as supporting compression. 112 Chapter 5

Using Your Digital Data Storage (DDS) Tape Drive
Operating the DDS Tape Drive
Archiving Data
This section describes how to transfer data to and from a DDS-format
data cassette (saving and restoring) using the HP-UX
tar
command and
your tape drive’s device file.
The
tar
command allows you to save files to a data cassette, restore files
from a data cassette to your system, or list the files on your data cassette.
Writing to a Data Cassette
Use the following instructions to save files to a data cassette:
1.
Check that the write-protect tab on the data cassette is in the write
position.
2.
Load the data cassette into the tape drive.
3.
In a terminal window, enter the following command line to write to
the tape:
tar -cvf /dev/rmt/
〈
devicefile
〉〈
pathname
〉
where
〈
devicefile
〉
is one of the device files listed from
ioscan
and
〈
pathname
〉
is the pathname of the file or directory containing files
that you want to write to the tape. To use the data-compression mode,
use one of the device file names that
sam
listed as supporting
compression.
