mechanism and record the information.
• Run the recommended tests.
Step 3. Consult Table 6-3, “Magneto-Optical Disk Library Configuration
Requirements,” to determine the device drivers needed for your
magneto-optical disk library and interface. If any necessary static device
driver is absent from the kernel, you will need to rebuild the kernel to
include it. Here is how to do so:
a. Change directory to the build environment (/stand/build). 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 gives
verbose explanation as the script executes.
cd /stand/build
/usr/lbin/sysadm/system_prep -v -s system
b. 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.
c. 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
d. 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
e. Prepare for rebooting by invoking the kmupdate command. This sets a
flag that tells the system to use the new kernel when it restarts.
/usr/sbin/kmupdate
