System boot process:

  • Power on
  • PDC executes CPU, Memory and other tests
  • PDC initialize the console to display messages
  • Looks for Primary boot path
  • It loads and executes Initial System Loader (ISL). Roll of boot ROM ends.
  • ISL loads the secondary system loader called “hpux”. It resides on boot area of the disk
  • “hpux” loads “/stand/vmunix” into memory and hands control over to kernel
  • Kernel loads the device drivers
  • Swapper process started. It has process ID 0. It manages memory for swapping in and out. It schedules all other process. Its first job is to startup the init process.
  • /sbin/pre_init_rc getting executed. It checks and repairs root file system.
  • /sbin/init started. Process ID is 1.
  • It refers /etc/inittab. It does the following.
    1. read the /etc/inittab for default run level
    2. ioinitrc – It invokes insf command with -e option to find any new devices.
    3. bcheckrc – activates LVM and run fsck on file systems if required.
    4. /sbin/rc – It brings the system to the default run level. This script is run whenever the system moves from to a higher one or vice versa.
    5. /usr/bin/getty
