Configuring HP-UX for any Peripheral (A Summary)

Prepare by gathering information required for the successful configuration of the peripheral. Considerations vary and are discussed in each peripheral-specific chapter. For example:

Have you prepared the physical location for the peripheral device?
To what interface are you connecting the peripheral?
What device drivers are required by the peripheral device?

In virtually all cases, the System Administration Manager (SAM) provides the simplest interface for configuring HP-UX for any standard peripheral device. If you must use the command line interface instead of SAM, the following procedure will familiarize you with the task.

Determine the device drivers needed for your peripheral device and interface by consulting the tables in the chapter devoted to that class of peripheral device. If any necessary device driver is absent from the kernel, you will need to rebuild the kernel to include it.
Here is how to rebuild the kernel:
1. Change directory to the build environment (/stand/build). There, execute a system preparation script, system_prep. system_prep writes a system file based on your current kernel in the 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
2. Edit the /stand/build/system file to add the absent driver(s).
3. Build the kernel by invoking the mk_kernel command. This creates /stand/build/vmunix_test, a kernel ready for testing.
  /usr/sbin/mk_kernel -s system
4. Save the old system file and kernel by moving them. Thus, if anything goes wrong, you still have a bootable kernel.
  mv /stand/system /stand/system.prev mv /stand/vmunix /stand/vmunix.prev
5. Move the new system file and new kernel into place, ready to be used when you reboot the system.
  mv /stand/build/system /stand/system mv /stand/build/vmunix_test /stand/vmunix
Notify users that the system must be rebooted.
Shut down and halt the system using the /usr/sbin/shutdown -h command.
1. When HALTED, you may cycle power appears on the screen, turn off the computer and unplug the power cord. This is recommended for all devices; for SCSI devices and interface cards, it is required.
2. Install the peripheral device, following directions in the supplied hardware documentation.
3. Power on the peripheral devices and wait for them to signal ready; then power on the computer system, which will cause your system to reboot. As HP-UX reboots, it will create the device special files required by the new peripheral device in the appropriate /dev directories.
Verify the configuration by invoking the ioscan command, as discussed earlier in this chapter.
