| | | |  | NOTE: Although this procedure refers explicitly to plotters,
it can be used to configure other devices that need the instr0 device driver on a Series 800 computer. | | | | |
Unlike printers, plotters cannot be automatically configured
by the kernel. Instead, you must manually ensure that the driver
is associated with the hardware path by using the capabilities of ioscan. Connect your plotter, noting the hardware
address to which you are connecting it and the HP-IB address to
which you are setting the plotter. In this example, we are configuring
an HP 7596A Draftmaster II to an HP-IB interface located in card-cage
slot 12 in a Model 806 computer. The HP-IB address is set to 5. Identify the hardware path to the plotter by invoking ioscan. An excerpt of the output might resemble the following: /usr/sbin/ioscan -f
Class I H/W Path Driver S/W State H/W Type Description
=================================================================
bc 0 root CLAIMED BUS_NEXUS
bc 1 56 bc CLAIMED BUS_NEXUS Bus Converter
lanmux 0 56/44 lanmux0 CLAIMED INTERFACE HP J2146A - 802.3 LAN
lan 1 56/44.1 lan3 CLAIMED INTERFACE |
The interface driver is hpib1 and the hardware path of interface card to which
the plotter is connected is 56/48 (hardware path equals slot number times four;
the bus converter is in slot 14, the interface card is in slot 12).
Neither the HP-IB address of the plotter nor the instr0 device driver is shown. Rebuild the kernel to include the instr0 driver. Here
is how to do so: Change
directory to the build environment (/stand/build). There, execute a system preparation script,
system_prep, which extracts the system file from the current
kernel and writes a system file in your current directory. (That is, it creates
/stand/build/system.) The -v provides verbose explanation as the script executes. cd /stand/build
/usr/lbin/sysadm/system_prep -v -s system |
Modify the /stand/build/system file to add the absent driver(s) by invoking the kmsystem command. The -c Y specifies that driver-name is to be configured
into the system. /usr/sbin/kmsystem -S /stand/build/system -c Y driver-name |
| | | | | NOTE: To avoid introducing format errors, do not edit the
HP-UX system description files directly. Instead, use the commands kmsystem and kmtune. These commands are new for Release 11.0; consult kmsystem(1M) and kmtune(1M) in
the HP-UX Reference. | | | | |
Build the new kernel by invoking the mk_kernel command. This creates /stand/build/vmunix_test, a kernel ready for testing. /usr/sbin/mk_kernel -s /stand/build/system |
Save the old system file by moving it. Then move the
new system file into place. mv /stand/system /stand/system.prev
mv /stand/build/system /stand/system |
Prepare for rebooting by invoking the kmupdate command. This sets a flag that tells the system
to use the new kernel when it restarts.
Reboot the system by invoking the shutdown command with sufficient grace period to allow
users to exit their files before the system goes down. See shutdown(1M) in
the HP-UX Reference. Bind the software driver used by the plotter (instr0) to the plotter's full hardware path (56/48.5) by executing /usr/sbin/ioscan with the -M and -H options. Then verify the results by executing ioscan again. As shown in the following sequence of commands and ioscan output, the device driver (instr0) associates with a peripheral device at address 56/48.5. The instr0 driver cannot identify any more specifically what instrument
is attached, but it can communicate with it. /usr/sbin/ioscan -M instr0 -H 56/48.5
/usr/sbin/ioscan -kf

Create a device special file for the plotter by invoking /usr/sbin/insf with the -H (hardware path) option; for example: /usr/sbin/insf -H 56/48.5 |
This installs the device special file for the hardware path
and instr0. You can verify this by executing ioscan -H 56/48.5 -fn to see the file name and then lssf filename to see the device file's attributes.
Your next step will be to configure the LP spooler to enable
you to send print jobs to the plotter; for procedure, see "Managing
Printers and Printer Output" of the Managing Systems
and Workgroups manual. |
