The Boot Process Boot Console Handler (BCH) Commands
nPartitions boot in a similar manner to any HP 9000. Figure 17-2 shows the high-level steps involved in booting an nPartition:
Figure 17-5. Boot Steps
BCH is the primary way to interact with an nPartition at boot time, just as it is on any HP 9000. The steps and interfaces of the boot process meld together. There are a few different interfaces and levels of boot through which you work. When you get to the main menu of the Management Processor and issue commands you are using BCH. When you get past BCH, you reach ISL, which is considered the next step of the boot process beyond BCH. Then you reach the secondary system loader, which we'll see in the upcoming example by issuing the hpux command, which attempts to load the kernel. You need to know at what level of the boot process you are work ing so you can issue the appropriate commands.
When you access the console for an nPartition that is idle, you would issue the BOOT command and then stop the boot process if you wish to get an ISL> prompt or allow the nPartition to boot automatically. The BCH and boot process in general are not much different for an nPartition than they are for a much smaller system covered in Chapter 1.
The following listing shows several steps that we'll perform to boot an nPartition in the upcoming example. I'll issue a variety of commands to give you an idea of some steps you can perform during the boot process at various prompts. We'll do the following:
- Go from the Management Processor to the Command Menu with cm.
- List the default customer LAN settings of the Management Processor with ls.
- Change the customer LAN settings with lc.
- List the new LAN settings with ls.
- Go back to the main Management Processor menu with ma.
- Go to the nPartition consoles with co.
- Select nPartition 0 with 0.
- Boot from the primary boot path with bo pri.
- Specify that we want to stop at the ISL prompt.
- List ISL commands with ?.
- Proceed the boot from the primary path with hpux.

We have only scratched the surface of BCH and other boot-related commands in this example and section. Knowing where you are in the boot process and the commands available to you is important in working with nPartitions, so that you can perform functions on the nPartition on which you're working or the complex in general.
