Configuring the Pass-Through Driver

Note These instructions are based on the HP-UX man page for scsi_pt (man 7

scsi_pt). Please refer to this man page if you need more details about any

aspect of the pass-through driver installation.

1 Type ioscan -f to determine the hardware path and LU for the autoloader.

The output should look something like this:

Class LU H/W Path Driver H/W Status S/W S

====================================================================================

bc - 0 bus_converter ok(0xc00) ok

scsi - 0/8 bus_converter.scsi1 ok(0x3980) ok

: : : : : :

scsi - 0/28 bus_converter.scsi1 ok(0x3980) ok

target - 0/28.0 bus_converter.scsi1.target ok(0x1800202) ok

tape_drive 1 0/28.0.0 bus_converter.scsi1.target.tape2 ok(0x1800202) ok

unknown - 0/28.0.1 bus_converter.scsi1.target.? ok(0x8c00202) No_Dr

: : : : : :

In this example:

n The DDS-3 autoloader resides on the SCSI adapter at hardware path 0/28

and has SCSI address 0.

n The DDS-3 drive in the autoloader (C1537A) is LUN 0 (0/28.0.0).

n The changer mechanism (C1557A) is LUN 1 (0/28.0.1).

2 Make a backup copy of the original /etc/master file:

cp /etc/master /etc/master.9_04

3 Edit the /etc/master file and make the following two changes:

a Add the text from the file /etc/contrib/bin/master.diff to your

/etc/master file where other drivers are defined.

b Add the library libspt.a to the loadorder statement in the

/etc/master file.

4 Make a backup copy of the kernel gen file in /etc/conf/gen (typically

named /etc/conf/gen/S800):

cp /etc/conf/gen/S800 /etc/conf/gen/S800.nospt

5 Edit the gen file (/etc/conf/gen/S800) and make the following two

changes:

a Add the include statement for the SCSI pass-through driver (spt) at the end

of the include statements:

include spt;

Add an io statement. The io statement is used to include drivers that do not

support autoconfiguration. The io statement is needed to map the spt driver
