Introduction

This booklet explains how to configure Scorpion 40 drives and

various Windows NT, UNIX and Novell operating systems for

optimum compatibility.

Operating-system configuration dip switches

The figure below shows the location of the operating-system

configuration dip switches on the bottom of the internal Scorpion 40.

Note: If the drive is to be used with an operating system other than

those described here, these switches should be left in their

default positions.

Configurations for Windows NT

If you use Windows NT 4.0 with the 4mmDAT.SYS driver from

Microsoft, you

must

set Switch 10 (the Inquiry-String switch) to OFF.

If you use Windows NT 4.0 with the STDAT4.SYS driver from

Seagate, you can leave the Switch 10 in to ON (the default setting).

In either case, switches 5 through 8, the UNIX configuration switches,

should all be set to ON (the default settings).

Configurations for the Novell environment

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).

Configuration 2:

If you use the

latest

Novell NWTAPE driver

(available on the Novell web site), the Operating-System

Configuration Dip switches should be left in their default positions (all

switches ON). From the administrator workstation, place the new

NWTAPE driver in the same directory as the TAPEDAI driver (usually

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

8 are OFF, as shown in the table on the front of this sheet. This is

different from their default settings (all switches ON).

(available on the Novell web site), the Operating-System

Configuration Dip switches can be left in their default positions (all

switches ON). Before installing the new NWTAPE driver, first rename

the old NWTAPE driver (usually found in the system directory). Then

copy the new version of NWTAPE into the same directory. Do not

delete the old driver, because it might come in handy in resolving

future problems.

DEC UNIX OFFONONON

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

Scorpion 40 configurations for Windows NT, Novell, and UNIX 6

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.

Digital UNIX Versions earlier than 4.0.

Configure the system by modifying the file

cam_data.c

. This

is located in either

/usr/sys/data

/sys/data

, depending on

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.

/* Seagate DAT Drive Returning "SEAGATE DAT" Inquiry */

{"SEAGATE DAT", 14, DEV_TLZ07,

ALL_DTYPE_SEQUENTIAL << DTYPE_SHFT) | SZ_RDAT_CLASS,

NO_OPT_CMDS, SZ_READY_DEF, SZ_NO_QUE,

DD_REQSNS_VAL | DD_INQ_VAL, 36, 64

4. Rebuild the kernel using the

doconfig

script. Then reboot the

system.

Sun UNIX ON OFF ON ON

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:

/*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),

5000,5000,

{0x0,0x8c,0x8c,0x8c},

{0,0,0,0}

}

3. Use the

config

command to rebuild the kernel and include the

new device definition. Refer to the

config

man page for details.

Solaris 2.x

1. To configure Solaris 2.x for compatibility with the Scorpion 40,

add the following lines to the file

st.conf

in the directory

/kernel/drv

tape-config-list=

"SEAGATE DAT 06240-XXX","Seagate DAT

Drive","SEAGATE_DAT";

SEAGATE_DAT = 1,0x34,0,0xd639,4,0x00,0x8C,0x8C,0x8C,3;

Note: The inquiry string above contains four spaces between the

word DAT and the value 06240.

2. After modifying the file

st.conf

, you must reconfigure the kernel

by booting the system using the

boot -r

command

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},

MTCAN_SILI|MTCAN_SEEK|MTCAN_CHTYPEANY,

/* minimum delay on i/o is 12 minutes, to allow the Drives

* full error recovery sequence to be performed. */

40, 12*60, 12*60, 12*60, 512, 512*512 },

Note: The string above contains four spaces between the word DAT

and the value 06240.

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.

Scorpion 40 configurations for Windows NT, Novell, and UNIX 10

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

MTCAN_SILI|MTCAN_SEEK|MTCAN_CHTYPEANY|MTCAN_COMPRESS,

/* minimum delay on i/o is 12 minutes, to allow the Drives

* full error recovery sequence to be performed. */

40, 12*60, 12*60, 12*60, 512, 512*512, 0, (u_char *)0 },

For IRIX V6.5:

{ 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

MTCAN_SILI|MTCAN_SEEK|MTCAN_CHTYPEANY|MTCAN_COMPRESS,

/* minimum delay on i/o is 12 minutes, to allow the Drives

* full error recovery sequence to be performed. */

40, 12*60, 12*60, 12*60, 3*3600, 512, 512*512,

Scorpion 40 configurations for Windows NT, Novell, and UNIX 11

tpsc_default_dens_count, tpsc_default_hwg_dens_names,

tpsc_default_alias_dens_names,

{0},0,0,0,

0, (u_char *)0 },

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.

Follow the steps below to configure these HP-UX systems:

1. Log in as root.

2. Run the SAM utility.

3. Choose the Peripheral Devices option.

4. Choose Tape Drives.

5. From the Actions menu in the Tape Device Manager window,

choose Add.

6. Within the Add a Tape Drive window, read the instructions, then

click on OK.

7. SAM may detect that your HP-UX kernel lacks the drivers

necessary to make use of your new tape drive. If so, within the

“Device Driver Check” window, read the message and choose

the appropriate action. If the chosen option is Build a new kernel

and shut down the system immediately, SAM will create a new

kernel, and automatically reboot the system. Once the system

comes back up, the necessary drivers will be loaded, and the

system will be able to use the tape drive.

8. If you had to shut down the system in order to physically connect

the tape drive, re-enter SAM and repeat steps 3 through 6 above.

9. Choose the new tape drive.

10. From the

Actions

menu, choose

Create Device Files.

11. Press OK and then exit from SAM.

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

Scorpion 40 configurations for Windows NT, Novell, and UNIX 15

• Set the “Maximum delay for the Read/Write command” to

900

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.
