If you want requests to space to end of data to be faster, you should also enable
ST_FAST_MTEOM
in the same file. After changing this file, rebuild the modules and install the
new binary. At the very least, this requires:
make modules
make modules_install
from the
/usr/src/linux
directory. See your kernel documentation.
Using the Seek and Tell Features of mt
In order to use the seek and tell features of
mt
, you must tell the
st
driver that HP Ultrium drives
use logical block addressing.
You can do this by using the command:
mt -f <device file> stsetoptions scsi2logical
where
/dev/stp
is the device file.
Note however that this information is not preserved across reboots, so you need to execute this
command each time the system comes up. The
stinit
utility offers a convenient way of
handling this; see the relevant
man
page for more information. If you use this approach, set the
manufacturer parameter to
HP
and the model to “
Ultrium 3-SCSI
”.

Once the device files have been created, you should confirm that your new tape drive is
working properly. Chapter 7, “Verifying the Installation” provides instructions on backing up
and restoring a sample file to test your installation.
