HP A3716A DDS-3 Autoloader User's Manual - 3716-96001

Installing Your Autoloader

Configuring the Pass-Through Driver
Note These instructions are based on the HP-UX man page for scsi_pt (man 7
scsi_pt) and should only be used if you are installing the autoloader onto an
NIO SCSI interface card. Please refer to this man page if you need more details
about any aspect of the pass-through driver installation.
1 Type ioscan -f
The output should look something like this:

In the example above, the autoloader is shown as a drive mechanism
(HP C1537A) at 36.0.0 and a changer mechanism (HP C1557A) at 36.0.1.
2 Go to the build area:
cd /stand/build
3 Create a system file from your existing kernel:
/usr/lbin/sysadm/system_prep -s system
4 Check if the SCSI pass-through driver is already configured into your current
kernel:
grep spt system
5 If no spt line was printed, make the following two changes to the system file:
a Add a line to the SCSI drivers area (/stand/build/system):
spt
A driver statement is needed since the system cannot autoconfigure the SCSI
pass-through driver. One statement is needed for the changer mechanism on
each autoloader.
b Append the driver line or lines to the system file:
driver <path> spt
where <path> is the complete hardware path of the autoloader (from
ioscan cmd).
