nPartition Administrator's Guide, Second Edition

The ACPI configuration settings for the supported OSes are in the following list.
— HP-UX ACPI Configuration: default On cell-based HP Integrity servers, to boot or install
the HP-UX OS, you must set the ACPI configuration value for the nPartition to default.
For details refer to “ACPI Configuration for HP-UX Must Be default” (page 110).
— HP OpenVMS I64 ACPI Configuration: default On cell-based HP Integrity servers, to
boot or install the HP OpenVMS I64 OS, you must set the ACPI configuration value for
the nPartition to default.
For details refer to “ACPI Configuration for HP OpenVMS I64 Must Be default”
(page 122).
— Windows ACPI Configuration: windows On cell-based HP Integrity servers, to boot or
install the Windows OS, you must set the ACPI configuration value for the nPartition
to windows.
For details refer to “ACPI Configuration for Windows Must Be windows” (page 127).
— Red Hat Enterprise Linux ACPI Configuration: single-pci-domain or default On cell-based
HP Integrity servers, to boot or install the Red Hat Enterprise Linux OS, you must set
the ACPI configuration value for the nPartition to either single-pci-domain or
default.
◦ On HP rx7620 servers, rx8620 servers, or Integrity Superdome (SD16A, SD32A,
SD64A), the ACPI configuration must be set to single-pci-domain.
◦ On HP rx7640 servers, rx8640 servers, or Integrity Superdome (SD16B, SD32B,
SD64B), the ACPI configuration must be set to default.
For details refer to “ACPI Configuration for Red Hat Enterprise Linux Must Be
single-pci-domain or default” (page 131).
— SuSE Linux Enterprise Server ACPI Configuration: single-pci-domain or default On
cell-based HP Integrity servers, to boot or install the SuSE Linux Enterprise Server OS,
you must set the ACPI configuration value for the nPartition to single-pci-domain
or default.
◦ On HP rx7620 servers, rx8620 servers, or Integrity Superdome (SD16A, SD32A,
SD64A), the ACPI configuration must be set to single-pci-domain.
◦ On HP rx7640 servers, rx8640 servers, or Integrity Superdome (SD16B, SD32B,
SD64B), the ACPI configuration must be set to default.
For details refer to “ACPI Configuration for SuSE Linux Enterprise Server Must Be
single-pci-domain or default” (page 133).
• ACPI Softpowerdown Configuration—OS Shutdown Behavior On HP rx7620, rx7640, rx8620,
and rx8640 servers, you can configure the nPartition behavior when an OS is shut down
and halted. The two options are to have hardware power off when the OS is halted, or to
have the nPartition be made inactive (all cells are in a boot-is-blocked state). The normal OS
shutdown behavior on these servers depends on the ACPI configuration for the nPartition.
You can run the acpiconfig command with no arguments to check the current ACPI
configuration setting; however, softpowerdown information is displayed only when different
from normal behavior.
To change the nPartition behavior when an OS is shut down and halted, use either the
acpiconfig enable softpowerdown EFI Shell command or the acpiconfig disable
softpowerdown command, and then reset the nPartition to make the ACPI configuration
change take effect.
— acpiconfig enable softpowerdown When set on HP rx7620, rx7640, rx8620, and rx8640
servers, acpiconfig enable softpowerdown causes nPartition hardware to be
