nPartition Administrator's Guide

NOTE: On Superdome SX1000 PA and SX2000 PA, shutdown -R -H does not stop
at BIB if the MP has been hot swapped since the last reboot.
On HP rx7620, rx7640, rx8620, and rx8640 servers with a default (to support HP-UX)
ACPI configuration setting a "wait at BIB" state is the default behavior, but the
acpiconfig enable softpowerdown EFI Shell command can be used to instead
cause all nPartition hardware to power off.
• HP OpenVMS I64 includes the following commands for shutting down and rebooting the
nPartition.
— @SYS$SYSTEM:SHUTDOWN.COM — Shuts down the OpenVMS I64 operating system.
The @SYS$SYSTEM:SHUTDOWN.COM command provides a series of prompts that you
use to establish the shutdown behavior, including the shutdown time and whether the
system is rebooted after it is shut down.
◦ To perform a reboot for reconfig from OpenVMS I64 running on an nPartition,
issue @SYS$SYSTEM:SHUTDOWN.COM from OpenVMS, and then enter Yes at the
"Should an automatic system reboot be performed" prompt
◦ To perform a shutdown for reconfig of an nPartition running OpenVMS I64: first
issue @SYS$SYSTEM:SHUTDOWN.COM from OpenVMS and enter No at the "Should
an automatic system reboot be performed" prompt, then access the MP and, from
the MP Command Menu, issue the RR command and specify the nPartition that is
to be shutdown for reconfig.
— RUN SYS$SYSTEM:OPCRASH — Causes OpenVMS to dump system memory and then
halt at the P00>> prompt. To reset the nPartition following OPCRASH, access the
nPartition console and press any key to reboot.
• 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.
