Seven new system administration commands are provided with
HP-UX 11i for creating and maintaining partitions on all Superdome
systems.
Modified Commands |
 |
The commands shutdown and reboot have been modified to support Superdome platforms. Two
new options -R and -H have been
added to both these commands. The -R option is
used to shut down the system to a "ready to reconfig" state
and reboot automatically. The -H option is used to
shut down the system to a "ready to reconfig" state
but without rebooting. The "ready to reconfig" state
is the state that a partition must be put into before new cells
that have been assigned to the partition can be active or to complete
the removal of cells that have been unassigned from the partition.
(A normal reboot will not activate newly assigned cells.) See Managing Superdome Complexes: A Guide for HP-UX System Administrators,
part no, B2355-90702 for more information. The default behavior
or the behavior of all the other existing options remain unchanged.
The interpretation of Autoboot and Autosearch in the command setboot has changed for systems that support hardware partitions.
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 Boot Console Handler (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.
If the alternate paths are not configured 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 alternate path to be automatically
booted when the primary path fails. Instead the user will be prompted.
A new field called the Root Cell Numberhas been
added to the bootpath in setboot, to support this command on the Superdome platform. The
bootpath displayed by setboot now includes Root Cell Numberon Superdome
platform. To set the bootpath using setboot, the user needs to include Root Cell Numberin
the bootpath.
