type, choice of slots or ID's, or conguration will result in slightly dierent listing.
The important thing is the presence of a tap e device reported as an HP35450A.
This is really a
DAT-Link
emulating an HP tape device.
The next step is to create a device le in the
/dev/rmt
directory. The
sam
system
management utility can b e used for this. Once
sam
is started select the
Peripheral
Devices
option, then the
Tape Drives
option. You should then have a list of
installed tap e devices including one for the
DAT-Link
which will have a line similar
to:
10/12/5.0.0 stape C1533A 4 GB DDS Data Compression Tape
Note again, that the details will change dep ending on the particular machine con-
guration. For example, the rst digit of the string '5.0.0' will always b e the SCSI
ID selected for the
DAT-Link
.
The next step is to select the line for the
DAT-Link
by p ositioning the cursor
over it and pressing return. You then need to use the
Actions
menu to select
the
Create Device Files
item. From there, select the
Create Default Devices
Files
choice. This will create a set of device les in
/dev/rmt
. You can see
the names of these device les bycho osing
Show Device Files
from the
Actions
menu. Note the short device name for the following step. Depending on the number
of tap e drives already installed this will probably b e
0m
or
1m
.
Finally, exit from
sam
and give the following command:
ln -s rmt/1m datlink0
where the
1m
should be replaced with the device name found ab ove. You can now
proceed with the software installation in Section 2.6 below.
