Scorpion 40 configurations for Windows NT, Novell, and UNIX 7

Configurations for the Sun UNIX environment

Dip switch settings

Before using the Scorpion 40 in a Sun UNIX environment, set the

operating-system dip switches as shown below:

Operating System / tape

driver software

Switch

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.
