Configuration for the Sun UNIX environment

Dip switch settings

Before using the Scorpion 240 in a Sun UNIX environment, set the operating-system dip switches as shown below:

		Switch 5	Switch 6	Switch 7	Switch 8
	Setting	ON	OFF	ON	ON
Sun OS 4.1.x

To configure SunOS 4.1.x to use the Scorpion 240, 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_VARIABLEST_BSFST_BSRST_LONG_ERASEST_KNOWS_EOD),

5000,5000,

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

{0,0,0,0}

}
