Novell 4.11
There are two possible ways to configure the Scorpion 40 to work
with Novell 4.11, depending on which tape driver you use.
Configuration 1:
If you are using the existing Novell TAPEDAI driver
or a version of the NWTAPE driver created before 11/3/99, you must
change the Operating-System Configuration Dip switches so that
switches 5 and 8 are OFF, as shown in the table below. This is
different from their default settings (all switches ON).

the system directory). Edit any .ncf files, such as autoexec.ncf, which
call the TAPEDAI driver and replace calls to TAPEDAI with
NWTAPE. Do not delete the TAPEDAI driver, because it may come
in handy in resolving future problems.

Novell 5.x
There are two possible ways to configure the Scorpion 40 to work
with Novell 5.x, depending on which tape driver you use.
Configuration 1:
If you are still using the original Novell NWTAPE
driver or any version created before 11/3/99, you must change the
Operating-System Configuration Dip switches so that switches 5 and

Digital UNIX Version 4.0 and later
With Version 4.0 of their UNIX operating system, DEC
introduced a new method of configuring the CAM SCSI driver.
Modify the file
/etc/ddr.dbase
as follows:
1. Look through the file and locate the database entry for the DEC
TLZ07 DAT drive
2. Copy this entry and paste it later in the file, taking care to
maintain the file syntax.
3. Modify this new entry as shown below.
SCSIDEVICE
#
Type = tape
Name = "SEAGATE" "DAT"
#
PARAMETERS:
TypeSubClass = rdat
TagQueueDepth = 0
MaxTransferSize = 0x0ffffff # (16MB - 1)
ReadyTimeSeconds = 60 # seconds
DENSITY:
#
DensityNumber = 0,3,4,5,6,7
DensityCode = default
CompressionCode = 0x0
Buffered = 0x1
DENSITY:
#
DensityNumber = 1,2
DensityCode = default
CompressionCode = 0x1
Buffered = 0x1

4. Save the database file.
5. Run the following command:
ddr_config -c.
This takes the
default input file, ddr.dbase, and builds a new device database.
The new device database is effective immediately, and there is
no need to rebuild the kernel.

the system configuration. The cam_data.c file should be
modified as shown below:
1. Look through the file to locate the database entry for the “TLZ07 RDAT” drive.
2. Make a copy of this entry and paste it later in the file, taking care
to maintain the syntax of the C source.
3. Modify the new entry as shown below.

Sun OS 4.1.x
To configure SunOS 4.1.x to use the Scorpion 40, you must modify
the
stdef.h
and
st_conf.c
files (in the directory /usr/sys/scsi/
targets), then rebuild the kernel, as described below:
1. Modify the
stdef.h
file by adding a define statement for the
Seagate drive like the one shown below:
#define ST_TYPE_SEAGATE_DAT <value>
This statement should be added after the last ST_TYPE_ define
statement in the file. <value> should be the next unused
hexadecimal value. This value will depend on the release and
number of devices supported by the system. For example, if the
last value for an existing device is 0x2d, then use a value of
0x2e.
2. Modify the
st_conf.c
file by adding the following lines at the end
of the device definition list:
3. Use the
/*Seagate DAT drive support */
{
“SEAGATE DAT”,7,”SEAGATE”,ST_TYPE_SEAGATE_DAT,10240,
(ST_VARIABLE|ST_BSF|ST_BSR|ST_LONG_ERASE|ST_KNOWS_EOD),

Note:
The main difference between tape drive support in Irix 5.x and
6.x is the introduction for Data Compression switching via
software in Irix version 6.2. When running Irix 5.x, the drive
will always operate in the compression setting determined by
switch 6 on the bottom of the drive (off=compression enabled
(default), on=compression disabled).
Irix V5.x
To configure Irix 5.x to use the Scorpion 40, you must modify the file
/var/sysgen/master.d/scsi as described below:
1. Edit the file
/var/sysgen/master.d/scsi
and add the following
entry:
{DATTAPE,TPDAT,7,12,"SEAGATE","DAT 06240"/*DAT*/,0,0,{0,0,0,0},

2. Rebuild the kernel using the autoconfig command (see the
autoconfig man page for details ). After the kernel is rebuilt you
will need to reboot the system again to bring the changes into
effect.

Note:
Irix 5.3 and later will detect the changes made and
automatically rebuild the kernel the next time the system
boots.
Irix V6.x through V6.5
To configure Irix 6.x-6.5 to use a Scorpion 40, you must modify the
files
/var/sysgen/master.d/scsi
and
/dev/MAKEDEV.d/TPS_base
as described below. After modifying these files you must rebuild the
kernel.
1. Edit the file
/var/sysgen/master.d/scsi
and add one of the
following entries, depending on your version of IRIX:
For IRIX V6.x through V6.4:
{ DATTAPE, TPDAT, 7, 12, "SEAGATE",”DAT 06240”/*DAT*/, 0, 0,
{0},
/* This drive uses mode select page 0xf for compression control;
* most of the other drives supporting compression use page 0x10

2.Edit the file
/dev/MAKEDEV.d/TPS_base
and make the following
modification (this modification is not required on systems running
IRIX 6.4 or 6.5).
Locate the area of code which deals with DAT drives. This starts
with:
*Drive?type:*DAT*
Then insert the following text before or after the similar entries for
other supported devices:
*Device:*DAT*06240*) # DAT drive with compression
;;
mdev=`expr $mdev + 8`;
mknod ${prf}$1c c ${C_TPS} $mdev;
3.Restart the system. Irix 6.x will detect the changes made and
automatically rebuild the kernel on startup.
Alternatively, you could manually rebuild the kernel using the
autoconfig command (see the autoconfig man page for details ),
then reboot the system again to bring the changes into effect.
Troubleshooting installations on the SGI platform
Checking the drive's inquiry string
It may be useful to confirm the drive’s inquiry string. This is done
using the mt command. The following command line will retrieve the
Inquiry string and other status data from a drive on SCSI bus 1, ID 4.
mt -f /dev/rmt/tps1d4 status
System Interchange Problems
If the following error appears when trying to restore a cpio archive
from another system, it is likely that a mistake was made in the
installation sequence in section 7.1 above:
Byte swapped Data - re-try with correct device
Scorpion 40 configurations for Windows NT, Novell, and UNIX 12
If this error is encountered, make sure that the correct modifications
were made to the file /var/sysgen/master.d/scsi.
Switching Hardware Compression
Irix 6.x provides support for software switching of hardware
compression through the use of different device drivers. Drivers
including a “c” in the device name should enable compression. You
may be able to resolve problems with data compression by installing
the latest Irix 6.x patch set.

AIX Version 3.2 and later
AIX Versions 3.2 and later can be configured to work with the
Scorpion 40 by using the SMIT “Other SCSI Tape Drive”
option
.
Note:
To use this procedure, you will need to know the SCSI ID
being used by the tape drive.
To configure AIX using the SMIT utility, use the following
procedure:
1. Enter SMIT at the Tape Drive menu by typing “smit tape”
2. Select “Add a tape drive”
3. Select the type of tape drive you will be adding. Use the “Other
SCSI Tape Drive” option.
4. Select the parent SCSI Adapter from the available list
5. The Add a tape Drive entry fields now appear. Some of the
standard options need to be changed to maximize drive
performance and functionality:
Set the “Connection Address” with the tape drive’s Target
•
and LUN (always use 0 for the LUN). In the list, the Target is
the first number and the LUN is the second. For example, if
the drive is ID 5, choose 5,0
Set the Fixed “Blocksize” to 1024
•
Set “Density 1” to 140
•

6. Press the
RETURN
key. The drive will be installed in the system
database and the appropriate devices created
7. Exit SMIT
Controlling data compression under AIX
After you run SMIT, device files will have been created for your new
tape drive. Typical filenames are listed below:
/dev/rmt0 /dev/rmt0.1 /dev/rmt0.2 /dev/rmt0.3
/dev/rmt0.4 /dev/rmt0.5 /dev/rmt0.6 /dev/rmt0.7
If you enter the configuration information specified in step 5 of the
configuration process, devices rmt0, rmt0.1, rmt0.2 and rmt0.3 will
cause the drive to write in compressed mode. Using devices rmt0.4,
rmt0.5, rmt0.6 and rmt0.7 will cause the drive to write with
compression disabled.
