HP-UX Operating System
Starting HP-UX
Step 4. Issue the OBP menu’s BOOT command to boot HP-UX on the V-Class
server.
You can set the server to automatically boot HP-UX if you have also set a
primary boot device (PRI). The OBP menu provides the AUTO BOOT
option, which causes the server to automatically boot HP-UX from the
primary boot device when AUTO BOOT is set to ON.
If a cabinet is already powered on before the SSP booted, the cabinet can
be reset from the SSP after it boots, using the do_reset command.
Boot variables
Several variables affecting the boot process can be set using the HP boot
(OBP) menu. For example, you can set the server to automatically
proceed to boot HP-UX by setting the AUTO BOOT option to ON and
setting the PRI boot path variable.
Boot variable settings are stored in non-volatile memory (NVRAM)
residing on the utility board of each V-Class server cabinet. These
variables are stored permanently until they are modified using the HP
boot menu interface. Refer to Chapter 4, “Firmware (OBP and PDC)” for
more information.
On multiple-cabinet V-Class servers the boot variable settings for the
monarch cabinet (cabinet ID 0) determine the server’s boot-time
behavior.
You should ordinarily need to interact with only the monarch cabinet’s
OBP menu, although the RC (RemoteCommand) option is available for
interacting with the OBP menus on other cabinets. See also “Assuming
control of the console” on page 51.
