HP Integrity rx8620 Server User Service Guide

E Operating System Boot and Shutdown
This appendix covers procedures for booting an operating system (OS) on an nPartition (hardware
partition) and procedures for shutting down the OS.
Operating Systems Supported on HP nPartition-capable Servers
HP supports nPartitions on HP 9000 servers and HP Integrity servers. The following list describes
the operating systems supported on the different nPartition-capable models.
• HP Integrity servers have Intel Itanium 2 processors and include the following
nPartition-capable models:
— HP Integrity Superdome (SD16A, SD32A, and SD64A models)
— HP rx8620
— HP rx7620
These HP Integrity servers run the following OSes:
— HP-UX 11i Version 2 (B.11.23) — See “Booting HP-UX” (page 205) for details.
— Microsoft® Windows® Server 2003 — See “Booting the Microsoft Windows Operating
System” (page 208) for details.
— Red Hat Enterprise Linux 3 Update 2 and Red Hat Enterprise Linux 3 Update 3 — See
“Booting the Red Hat Linux Operating System” (page 210) for details.
— SuSE Linux Enterprise Server 9 — See “Booting the SuSE Linux Enterprise Server
Operating System” (page 211)for details.
System Boot Configuration Options
This section briefly discusses the system boot options you can configure on nPartition-capable
servers. You can configure boot options that are specific to each nPartition in the server complex.
HP Integrity Boot Configuration Options
On nPartition-capable HP Integrity servers you must properly specify the ACPI configuration
value, which affects the OS startup process and on some servers can affect the shutdown behavior.
You also can configure boot device paths and the autoboot setting for the nPartition. Details are
given in the following list.
• Boot Options List—HP Integrity Server Boot Device Paths You can manage the boot options
list for each nPartition either by using the bcfg command at the EFI Shell, or by using the
Add a Boot Option, Delete Boot Option(s), and Change Boot Order menu
items at the EFI Boot Option Maintenance menu.
To set boot options from HP-UX use the setboot command.
• Autoboot Setting You can configure the autoboot setting for each nPartition either by using
the autoboot command at the EFI Shell, or by using the Set Auto Boot TimeOut menu
item at the EFI Boot Option Maintenance menu.
To set autoboot from HP-UX, use the setboot command.
• ACPI Configuration Value—HP Integrity Server OS Boot On nPartition-capable HP Integrity
servers you must set the proper ACPI configuration for the OS that will be booted on the
nPartition.
To check the ACPI configuration value, issue the acpiconfig command with no arguments
at the EFI Shell.
To set the ACPI configuration value, issue the acpiconfig value command at the EFI Shell,
where value is either default, windows, or single-pci-domain. Then reset the nPartition
by issuing the reset EFI Shell command for the setting to take effect.
