nPartition Administrator's Guide, Second Edition

• Microsoft® Windows® includes the following commands for shutting down and rebooting
the nPartition.
— shutdown /r — Shuts down Windows 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 /s — Shuts down Windows and performs a shutdown for reconfig of the
nPartition. The default behavior differs on HP Integrity Superdome servers and HP
Integrity HP rx7620, rx7640, rx8620, and rx8640 servers.
On HP Integrity Superdome servers, shutdown /s causes all cells to be reset and
nPartition reconfiguration to occur as needed. All cells then remain at a "wait at BIB"
state and the nPartition is inactive
On HP Integrity HP rx7620, rx7640, rx8620, and rx8640 servers, the default behavior is
for shutdown /s to cause nPartition hardware to be powered off. On HP rx7620,
rx7640, rx8620, and rx8640 servers with a windows ACPI configuration setting, the the
acpiconfig disable softpowerdown EFI Shell command can be used to instead
cause all cells to instead remain at a "wait at BIB" state.
• Red Hat Enterprise Linux and SuSE Linux Enterprise Server include the following commands
for shutting down and rebooting the nPartition.
— shutdown -r time — Shuts down Linux 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.
The required time argument specifies when the Linux shutdown is to occur.
You can specify time in the format hh:mm, in which hh is the hour (one or two digits)
and mm is the minute of the hour (two digits); or in the format +m, in which m is the
number of minutes delay until shutdown; or specify now to immediately shut down.
— shutdown -h time — Shuts down Linux 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.
The required time argument specifies when the Linux shutdown is to occur.
On HP rx7620, rx7640, rx8620, and rx8640 servers with an ACPI configuration setting
of single-pci-domain, a "wait at BIB" state is the default OS shutdown for reconfig
behavior, but the acpiconfig enable softpowerdown EFI Shell command can be
used to instead cause all nPartition hardware to power off.
For details see Chapter 5 (page 87).
Complex Profile
The configurable aspects of a server complex are represented in a set of data called the "Complex
Profile", which determines how hardware is assigned to and used by nPartitions within a server.
