Windows Integrity nPartition Guide

Using Other Tools for Managing nPartitions

nPartition-level tasks

Chapter 4

To change the nPartition behavior when an OS is shutdown 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, acpiconfig enable softpowerdown causes nPartition hardware to be

powered off when the operating system issues a shutdown for reconfig command

(for example, shutdown -h or shutdown /s).

This is the normal behavior on mid-range servers with a windows ACPI

configuration setting.

When softpowerdown is enabled on a mid-range server, if one nPartition is defined

in the server then halting the operating system powers off the server cabinet

(including all cells and I/O chassis). On a mid-range server with multiple

nPartitions, halting the operating system from an nPartition with softpowerdown

enabled causes only the resources on the local nPartition to be powered off.

To power on hardware that has been powered off, use the PE command at the

management processor command menu.

— acpiconfig disable softpowerdown

When set, acpiconfig disable softpowerdown causes nPartition cells to

remain at a boot-is-blocked state when the operating system issues a shutdown

for reconfig command (for example, shutdown -h or shutdown /s). In this case an

OS shutdown for reconfig makes the nPartition inactive.

This is the normal behavior on mid-range servers with an ACPI configuration

setting of default or single-pci-domain.

To make an inactive nPartition active, use the management processor BO

command to boot the nPartition past the boot-is-blocked state.

Find bootable devices

Find bootable devices using the following procedure:

Find bootable devices [EFI shell]

From the EFI Shell environment, issue the map command to list bootable devices.

Step 1. Access the EFI Shell environment for the nPartition whose bootable devices you want to

list.

nPartition console.

When accessing the console, confirm that you are at the EFI Boot Manager menu (the

main EFI menu). If at another EFI menu, select the

Exit option from the sub-menus until

you return to the screen with the EFI Boot Manager heading.

From the EFI Boot Manager menu, select the

EFI Shell menu option to access the EFI

Shell environment.

Step 2. At the EFI Shell, issue the map command to list all disk devices with a potentially

bootable EFI System Partition.
