Conﬁguring Disk Drives, Disk Arrays, and CD-ROM Drives

Conﬁguring HP-UX for a New Disk Device

The simplest way to conﬁgure a disk device (hard disk, ﬂoppy disk, disk

array, or CD-ROM) is to use SAM (/usr/sbin/sam). If SAM is not loaded

on your system or if you prefer to use the command-line interface, the

following procedure will guide you through the task. Familiarize yourself

with the instructions before getting started.

Step 1. Invoke /usr/sbin/ioscan

-fn to ﬁgure out what addresses are available on the interface card to

which you will be attaching the disk.

For examples of ioscan usage, consult "Using ioscan to Display yourI/O

Conﬁguration," in Appendix B of this book.

Step 2. Consult the tables in the previous section ( “Selecting Device Drivers for

a Disk Device and Interface”) to determine the device driver(s) needed

for your disk and interface. (If you are conﬁguring a magneto-optical

device, use the table in the section, Magneto-Optical Disk Conﬁguration

Guidelines, found in the next chapter.) If any necessary static driver is

absent from the kernel, you will need to rebuild the kernel to include it.

Here is how to rebuild the kernel:

Step 3. 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, as follows:

cd /stand/build

/usr/lbin/sysadm/system_prep -v -s system

The system_prep script writes a system ﬁle in your current directory

(that is, it creates /stand/build/system). The -v gives verbose

explanation as the script executes.

Step 4. 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
