Re: booting process of rp8420
I don't understand what "step by step process of rp8420 server " means, but if you want to boot to single user mode, just stop at the boot menu (BCH), boot from the (primary) disk, interact with ISL:
Main Menu: Enter command or menu > bo pri
Interact with IPL (Y, N, or Cancel)?> y
Booting...
Boot IO Dependent Code (IODC) revision 1
HARD Booted.
ISL Revision A.00.38 OCT 26, 1994
ISL> hpux -is
Hope this helps!
Regards
Torsten.

Re: booting process of rp8420
The boot process of an HP-9000 (rp8420) server starts when you power it on or when you reboot a running system. It can be divided into two main parts.
boot ROM startup
HP-UX startup
In the first stage, the boot ROM startup process is carried out. At its completion, it initiates the HP-UX startup process, which is completed in a number of steps. On an abstract level, the boot sequence can be divided into the following steps.
Power on or reboot.
The processor dependent code (PDC) executes and performs self-tests. These tests include memory and CPU tests. The PDC also detects any peripherals attached to the system.
PDC initializes the console to display messages. It looks for the primary boot path for booting the system. The boot path is the hardware path to the disk used as the boot device.
PDC loads and executes the initial system loader (ISL) from the boot path and executes it. At this stage in the startup process, the role of the boot ROM ends.
ISL loads the secondary system loader known as hpux, which resides on the boot area of the disk.
The hpux loads the HP-UX kernel /stand/vmunix into memory and hands control over to the kernel.
The kernel starts the swapper process and then the init process.
The init process reads its initialization file, /etc/inittab, and initializes most of the operating system daemons and processes. It brings the system into an appropriate state and makes it usable for users.
As soon as the init process has completed its tasks, you see a login prompt at the console or at any terminal attached to the system.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
On BCH(Boot Console Handler)
To discontinue, press any key within 10 seconds.
Boot terminated.
Main Menu: Enter command or menu > BO PRI
To boot the system in single-user mode for system administration purposes, use:
ISL> hpux -is
