Troubleshooting Boot Problems

On HP cell-based servers, you might encounter different boot issues than on other HP servers.
The following boot issues are possible on cell-based servers.
• Problem: On an HP Integrity server, HP-UX begins booting but is interrupted with a panic
when launching the HP-UX kernel (/stand/vmunix).
Causes: The nPartition ACPI configuration might not be properly set for booting HP-UX.
In order to boot the HP-UX operating system an nPartition must have its acpiconfig value
set to default.
Actions: At the EFI Shell interface, enter the acpiconfig command with no arguments to
list the current ACPI configuration for an nPartition. If the acpiconfig value is set to
windows, then HP-UX cannot boot; in this situation you must reconfigure acpiconfig.
To set the ACPI configuration for HP-UX: at the EFI Shell interface enter the acpiconfig
default command, and then enter the reset command for the nPartition to reboot with
the proper (default) configuration for HP-UX.

Summary
• BCH Menu: the PATHFLAGS command from the BCH Configuration menu sets
boot-time actions for an nPartition.
To set the boot actions for an nPartition boot paths, enter:
PATHFLAGS VAR action
where VAR is the boot path variable (PRI, HAA, or ALT) and action is the boot action
(0 for "go to BCH", 1 for "boot, if fail go to BCH", 2 for "boot, if fail try next path", or 3
for "skip this path, try next path").
• EFI Boot Manager: Boot Option Maintenance Set Auto Boot TimeOut operation.
• EFI Shell: autoboot command.
For example: autoboot off to disable autoboot, or autoboot 60 to enable autoboot
with a 60-second timeout period.
• HP-UX: setboot -b on or setboot -b off command, to turn on (enable) or turn
off (disable) autoboot.

• NOTE: HP recommends that all self tests be performed.
• BCH Menu: Configuration menu FASTBOOT command: enter FASTBOOT to list settings;
enter FASTBOOT RUN to enable all tests; enter FASTBOOT TEST RUN or FASTBOOT
TEST SKIP to enable or disable an individual test.
• EFI Shell: boottest command to list settings; boottest on to enable all tests;
boottest off to disable all tests. To configure a specific test, use the boottest
test on or boottest test off command.
• HP-UX B.11.11: setboot -t testname=value to configure the test for all following
boots, or setboot -T testname=value to configure the test for the next boot only.
setboot -v to list settings.
• HP-UX B.11.23 and B.11.31: setboot -t testname=value to configure the test for the
next boot only. setboot -v to list settings.
