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 mid-range 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 mid-range servers, the default behavior is for shutdown /s to cause
nPartition hardware to be powered off. You can use the EFI Shell
command acpiconfig disable softpowerdown instead to make all
cells remain at a “wait at BIB” state.
