Configuring HP-UX For Peripherals

Getting Started

Conﬁguring HP-UX for any Peripheral (A Summary)

(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 2. Notify users that the system must be rebooted.

Step 3. Shut down and halt the system using the /usr/sbin/shutdown -h

command.

a. 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.

b. Install the peripheral device, following directions in the supplied

hardware documentation.

c. 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.

NOTE Before attempting to reboot using the new kernel, the system startup

scripts save a copy of the old kernel in /stand/vmunix.prev. If the new

kernel won't boot, use this copy of the old kernel, together with the copy

of the old system ﬁle you saved in /stand/system.prev, to restart the

system.

Step 4. Verify the conﬁguration by invoking the ioscan command, as discussed

earlier in this chapter.
