or customize the nodes.
More information about this process and what files are created, can be found in

7.1.2 Booting Problems

Figure 77. Booting Problems
The booting process has several components that work together to accomplish
the tasks of network booting, installing, and customizing a node. During the first
steps of this process, you have to specify who will serve the nodes you want to
install. Along with that, you set the boot responds to install or customize in the
SDR. Finally, you run setup_server. This script executes several NIM
commands to allocate the necessary NIM resources to each client. Note that if
you are installing several nodes with several NIM masters, setup_server will run
in each one of the NIM masters that will be part of this installation or
customization.
If you encounter problems running setup_server, look at 2.9.2, "Setup_server
Fails" on page 56, which covers those kinds of problems. However, after
running setup_server successfully, you are about to start the booting process.
To start installing or customizing your nodes, you must reboot them or power
them on, if they were powered off. When they start booting, you will see the LED
in the panel display.
The LED numbers are very useful to determine which step is being executed. In
the chart, you see LED numbers indicating where nodes usually get stuck, for
several reasons.
