HP 9000 rp8420 Server - User Service Guide, Fifth Edition

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 9000 servers have PA-RISC processors and including the following nPartition-capable
models:
— HP 9000 Superdome (SD16A, SD32A, and SD64A models)
— HP rp8420, rp8400
— HP rp7420, rp7405/rp7410
See “Booting HP-UX” (page 195) for details on booting an OS on these servers.
These HP 9000 servers run HP-UX 11i Version 1 (B.11.11). These HP 9000 servers also run
the September 2004 or later release of HP-UX 11i Version 2 (B.11.23). Releases of HP-UX
B.11.23 prior to September 2004 do not support HP 9000 servers.
• 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 195) for details.
— Microsoft® Windows® Server 2003 — See “Booting the Microsoft Windows Operating
System” (page 202) 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” for details.
— SuSE Linux Enterprise Server 9 — See “Booting the SuSE Linux Enterprise Server
Operating System” 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 9000 Boot Configuration Options On nPartition-capable HP 9000 servers the configurable
system boot options include boot device paths (PRI, HAA, and ALT) and the autoboot setting for
the nPartition. To set these options from HP-UX use the setboot command. From the BCH
system boot environment, use the PATH command at the BCH Main menu to set boot device
paths, and use the PATHFLAGS command at the BCH Configuration menu to set autoboot options.
For details issue HELP command at the appropriate BCH menu, where command is the command
for which you want help.
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
