HP Integrity rx7640, Service Manual

• To perform a reboot for reconfiguration of an nPartition:
shutdown -R
• To hold an nPartition at a shutdown for reconfiguration state:
shutdown -R -H
For details, refer to the shutdown(1M) manpage.
NOTE: On HP rx7620, rx7640, rx8620, and rx8640 servers, you can configure the nPartition
behavior when an OS is shut down and halted (
shutdown -h
or
shutdown -R -H
). The two
options are to have hardware power off when the OS is halted, or to have the nPartition be made
inactive (all cells are in a boot-is-blocked state).
The normal behavior for HP-UX shut down and halt is for the nPartition to be made inactive.
For details, refer to “ACPI Softpowerdown Configuration—OS Shutdown Behavior” (page 92) .
Procedure 4-9 Shutting Down HP-UX
From the HP-UX command line, issue the
shutdown
command to shut down the HP-UX OS.
1. Log in to HP-UX running on the nPartition that you want to shut down.
Log in to the management processor for the server and use the Console menu to access the
system console. Accessing the console through the MP enables you to maintain console
access to the system after HP-UX has shut down.
2. Issue the
shutdown
command with the appropriate command-line options.
The command-line options you specify dictate the way in which HP-UX is shut down,
whether the nPartition is rebooted, and whether any nPartition configuration changes take
place (for example, adding or removing cells).
Use the following list to choose an HP-UX shutdown option for your nPartition:
• Shut down HP-UX and halt the nPartition.
On cell-based HP Integrity servers, the
shutdown -h
command puts an nPartition
into the shutdown for reconfiguration state; for details, refer to the discussion of
shutdown -R -H
in this list.
• Shut down HP-UX and reboot the nPartition.
Issue the
shutdown -r
command to shut down and reboot the nPartition.
On cell-based HP Integrity servers, the
shutdown -r
command is equivalent to the
shutdown -R
command.
• Perform a reboot for reconfiguration of the nPartition.
Issue the HP-UX
shutdown -R
command to perform a reboot for reconfiguration.
This shuts down HP-UX, reconfigures the nPartition if needed, and reboots the
nPartition.
• Reboot the nPartition and put it into the shutdown for reconfiguration state.
Use the HP-UX
shutdown -R -H
command to hold the nPartition in the shutdown
for reconfiguration state.
This leaves the nPartition and all its cells in an inactive state (the nPartition can be
reconfigured remotely), unless the normal behavior has been modified. For details,
refer to
“ACPI Softpowerdown Configuration—OS Shutdown Behavior” (page 92) .
To reboot the nPartition, you must do so manually by using the
BO
command at the
management processor Command Menu.
If HP-UX is halted on the nPartition, thus not allowing you to use the
shutdown
command,
you can reboot or reset the nPartition by issuing commands from the management processor
Command Menu.
