Configuring HP-UX For Peripherals

Chapter 5 157
Configuring Disk Drives, Disk Arrays, and CD-ROM Drives
Configuring into your System an LVM Disk Already Containing Data
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
Step 8. Bring the system down and physically install the disk device.
Step 9. Turn on the power to all peripheral devices. Wait for them to become
"ready", then turn on power to the SPU.
Step 10. Watch the boot up sequence and record the name of the block device
special file created for the new LVM disk.
You can also identify the disk device by using the ioscan command.
/usr/sbin/ioscan
-fn -C disk will display all disks and their device special files. Or, you
can use /usr/sbin/ioscan -H hardware_path -fn to identify the disk
