HP-UX Reference (11i v2 03/08) - 1M System Administration Commands N-Z (vol 4)

s
setboot(1M) setboot(1M)
setboot -t late_cpu=off
4. Reset all tests to the machine-shipped default values.
setboot -t all=default
5. Reset only the
FASTBOOT (full_memory and PDH) tests to their default values.
setboot -t FASTBOOT=default
6. Cause the early and late CPU tests to be executed on the next system boot. The previously set test
values take effect again after the single boot.
setboot -T SELFTESTS=on
7. Cause all tests to be skipped on the next reboot. The previously set test values will take effect for
subsequent reboots.
setboot -T all=off
WARNINGS
The setboot command fails under the following circumstances:
• The number of writes to the stable storage exceeds the number allowed by the architecture imple-
mentation.
• Hardware failure.
• The implementation does not have memory for the alternate boot path, in which case, this variable
is neither readable nor writable.
The interpretation of Autoboot and Autosearch has changed for systems that support hardware parti-
tions. The firmware interprets the bits in combination and not individually as done before. In order to
approximate the traditional behavior of
setboot, the user input for the autoboot and autosearch flags
is internally mapped to the right combination to achieve the desired behavior. This mapping should be
transparent to the user of setboot, but might show up when accessing the firmware using means
other than setboot.
For the primary path, the boot action corresponds to the Autoboot and Autosearch flags in the following
manner:
AutoBoot AutoSearch Boot Action
off off Go to the BCH and prompt the user.
on off Attempt the primary path; on failure
go to BCH.
on on Attempt the primary path; on failure
try next path.
off on Skip the primary path and try alternate path.
If the alternate paths are not configured to
boot or fail, go to BCH.
Additionally, systems with hardware partitions support a boot action for each path. However the boot
action for the paths other than the primary path cannot be set using setboot. Instead, these must be set
through the Boot Console Handler using the pf command. The default boot action for the hardware
partitions is to "skip this device and try next path". The case where both the autosearch and autoboot
flags are on, will not work as expected until the path flags for the alternate paths are set appropriately
through the BCH. In the default case, specifying setboot -b on -s on will not cause an alter-
nate path to be automatically booted when the primary path fails, instead the user will be prompted.
DEPENDENCIES
If SpeedyBoot is not installed on a system, options
-v, -t, and -T will produce a diagnostic error.
Currently -t option is not supported on Itanium-based architecture.
