System Boot Configuration Options
This section briefly discusses the system boot options you can configure on nPartition-capable servers. You
can configure boot options that are specific to each nPartition in the server complex.
HP 9000 Boot Configuration Options
On nPartition-capable HP 9000 servers the configurable system boot options include boot device paths (PRI,
HAA, and ALT) and the autoboot setting for the nPartition. To set these options from HP-UX use the setboot
command. From the BCH system boot environment, use the PATH command at the BCH Main menu to set
boot device paths, and use the PATHFLAGS command at the BCH Configuration menu to set autoboot options.
For details issue HELP command at the appropriate BCH menu, where command is the command for which you
want help.
HP Integrity Boot Configuration Options
On nPartition-capable HP Integrity servers you must properly specify the ACPI configuration value, which
affects the OS startup process and on some servers can affect the shutdown behavior. You also can configure
boot device paths and the autoboot setting for the nPartition. Details are given in the following list.
• Boot Options List—HP Integrity Server Boot Device Paths
You can manage the boot options list for each nPartition either by using the bcfg command at the EFI
Shell, or by using the
Add a Boot Option, Delete Boot Option(s), and Change Boot Order menu items at the
EFI
Boot Option Maintenance menu.
To set boot options from HP-UX use the setboot command.
• Autoboot Setting
You can configure the autoboot setting for each nPartition either by using the autoboot command at the
EFI Shell, or by using the
Set Auto Boot TimeOut menu item at the EFI Boot Option Maintenance menu.
To set autoboot from HP-UX use the setboot command.
• ACPI Configuration Value—HP Integrity Server OS Boot
On nPartition-capable HP Integrity servers you must set the proper ACPI configuration for the OS that
will be booted on the nPartition.
To check the ACPI configuration value, issue the acpiconfig command with no arguments at the EFI
Shell.
To set the ACPI configuration value, issue the acpiconfig value command at the EFI Shell, where
value is either default, windows, or single-pci-domain. Then reset the nPartition by issuing the
reset EFI Shell command for the setting to take effect.
The ACPI configuration settings for the supported operating systems are in the following list.
— HP-UX ACPI Configuration: default
On nPartition-capable HP Integrity servers, to boot or install the HP-UX operating system an
nPartition must have its ACPI configuration value set to default.
For details see “ACPI Configuration for HP-UX Must Be “default”” on page 176.
