nPartition Administrator's Guide

To boot Windows Server 2003, the ACPI configuration setting for the nPartition must
be set to windows.
To boot Red Hat Enterprise Linux or SuSE Linux Enterprise Server:
◦ 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.
— acpiconfig enable softpowerdown — When set, causes nPartition hardware to
be powered off when the operating system issues a shutdown for reconfig command.
On HP rx7620, rx7640, rx8620, and rx8640 servers with a windows ACPI configuration
setting, this is the default behavior. Available only on HP rx7620, rx7640, rx8620, and
rx8640 servers.
— acpiconfig disable softpowerdown — When set, causes nPartition cells to
remain at BIB when the operating system issues a shutdown for reconfig command. In
this case an OS shutdown for reconfig makes the nPartition inactive. On HP rx7620,
rx7640, rx8620, and rx8640 servers this is the normal behavior for nPartitions with an
ACPI configuration setting of default or single-pci-domain. Available only on
HP Integrity rx7620, rx7640, rx8620, and rx8640 servers.
— reset — Resets the local nPartition, resetting all cells and then proceeding with the
nPartition boot phase.
— reconfigreset — Performs a shutdown for reconfig of the local nPartition, resetting
all cells and then holding them at the "wait at BIB" state, making the nPartition inactive.
• BCH menu support for managing nPartition booting includes the following commands.
(BCH is available only on HP 9000 servers.)
— BOOT — Initiate an operating system boot from a specified boot device path or path
variable.
— REBOOT — Resets the local nPartition, resetting all cells and then proceeding with the
nPartition boot phase.
— RECONFIGRESET — Performs a shutdown for reconfig of the local nPartition, resetting
all cells and then holding them at the "wait at BIB" state, making the nPartition inactive.
— PATH — List and set boot device path variables (PRI, HAA, ALT).
— Configuration menu, PATHFLAGS command — List and set the boot control flag for
each boot path, effectively determining the nPartition autoboot behavior.
• HP-UX includes the following commands for shutting down and rebooting the nPartition.
— shutdown -r — Shuts down HP-UX and resets the local nPartition, resetting cells and
then proceeding with the nPartition boot phase.
On HP 9000 servers shutdown -r resets only the active cells.
On HP Integrity servers shutdown -r has the same effect as shutdown -R. All cells
are reset and nPartition reconfiguration occurs as needed.
— shutdown -h — On HP 9000 servers, shuts down HP-UX, halts all processing on the
nPartition, and does not reset cells.
On HP Integrity servers, shutdown -h has the same effect as shutdown -R -H and
results in a shutdown for reconfig.
— shutdown -R — Shuts down HP-UX and performs a reboot for reconfig of the
nPartition. All cells are reset and nPartition reconfiguration occurs as needed. The
nPartition then proceeds with the nPartition boot phase.
— shutdown -R -H — Shuts down HP-UX and performs a shutdown for reconfig of the
nPartition. All cells are reset and nPartition reconfiguration occurs as needed. All cells
then remain at a "wait at BIB" state and the nPartition is inactive.
