Booting on HP 9000 Servers (part 4) - HPUX Secondary System Loader (hpux)

The hpux utility manages loading the HP-UX kernel and gives control to the kernel. ISL can have hpux run an “autoexecute” file, or commands can be given interactively. In most situations, you just want to automatically boot the system, however, in this example so far, I decided to interact with IPL in the interest of looking at some of the functionality in ISL. I proceed with the boot process by simply issuing the HPUX utility name, as shown in the following example:

ISL> hpux

GenericSysName [HP Release B.11.11] (see /etc/issue)


					  

I abbreviated this listing where the three dots appear before the Console Login: prompt.

There are several volumes on an external HP storage unit on which fsck is run to perform a sanity check. 

I can issue with the HPUX utility. Table 4 shows examples of some common HPUX utility booting options.

Table 4. hpux Examples

Command (All at ISL> Prompt)	Comments
Automatic Boot	No interaction - autoboot sequence.
hpux -is	Brings up system at run level s for single user mode.
hpux	Default boot sequence from autoexecute, normally, object file is /stand/vmuinx.
hpux vmunix.test	Boots object file vmunix.test.
hpux (52.5.0.0) /stand/vmunix	Boots from /stand/vmunix on the disk at the path 52.5.0.0.
hpux lan(32) /stand/vmunix	Boots from LAN.
hpux -v	Gets HP-UX version numbers.
hpux ll /stand	Lists contents of /stand on root disk.

The part of the boot that takes place after the hpux command is issued is in four parts:

1. HP-UX initializes the system hardware and devices - The HP-UX kernel locates and initializes system hardware such as memory, I/O busses and devices, and so on. Kernel device drivers are associated with I/O devices at this time. You see many messages fly-by on the system console as this process is taking place.

2. HP-UX kernel data structures are created and initialized - Many tables for system processes and memory, file systems, and so on are created. You also see the status of this part of the boot on the system console.

3. HP-UX searches for the root file system - The base file system contains critical system files and is usually found on the disk from which HP-UX boots. Many commands are run as part of this process.

4. HP-UX starts the init process called /sbin/init - The init process, which has an ID of one, starts all other processes on the system. The init process reads /etc/inittab for direction.

I encourage you to issue some of the PDC, ISL, and hpux utility commands covered earlier, especially those that do not modify your system in any way but only provide information about the system.
