Peripheral Configuration in Its Simplest Terms

HP-UX version 11.00.01 Getting Started 1-5

Using SAM to Configure Peripherals

The System Administration Manager (SAM) provides the easiest way to view your

Continuum system configuration and configure the peripheral device drivers into

the kernel. To invoke SAM, enter

sam

SAM’s user interface and online help system allow you to discover the

configuration information as you proceed through its screens. Once you provide

SAM with basic information about the device being configured, SAM performs the

following steps:

1. Checks your currently running kernel configuration file for the required

device drivers

2. Reports whether or not the drivers are present

3. Adds them (if necessary)

4. Reconfigures the kernel (if necessary)

For some devices, SAM also automates other necessary steps. For example, when

adding a terminal to your Continuum system, SAM edits the /etc/inittab file

to add the terminal entry. You have to perform this step manually if you are not

using SAM to configure the terminal.

Using Commands to Configure Peripherals

You must use HP-UX operating system commands to configure peripherals to the

system if the device cannot be automatically configured or if SAM is not on your

system.

Most Stratus peripherals are configured automatically. Each peripheral-specific

chapter of this book gives procedures for using HP-UX operating system

commands and Stratus-specific commands for configuration. Most Stratus

peripherals can be configured into a running Continuum system without

rebooting.

Third-party drivers and certain drivers used for instrumentation or “black-box”

applications are not recognized by insf to create device files automatically during

the reboot process.

If you are adding a peripheral device requiring a driver that cannot be configured

automatically, you must configure the device driver and create the device files

using the ioscan and mksf or mknod commands.

Read the /usr/conf/master.d/core-hpux file and the master(4) man page for

information about the architectural-context dependencies.
