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_VARIABLE|ST_BSF|ST_BSR|ST_LONG_ERASE|ST_KNOWS_EOD),
5000,5000,
{0x0,0x8c,0x8c,0x8c},
{0,0,0,0}
}
