clbootnodes will gain console access by using telnet to reach the MP. clbootnodes uses a library called Expect to produce the input needed to gain access to the console and step through the boot processes. There are times when manual intervention is necessary. In these cases, a message will be displayed explaining why control is being returned to the user. The user can then interact with the MP/console and then return control to clbootnodes by pressing '~'. Control may be given to the user for the following reasons:

The MP is password protected.

A LAN card choice was not specified to clbootnodes.

clbootnodes is intended to boot a node or nodes through the first boot sequence. It can generally be run at any time to ensure that a node is booted and can usually recognize if the console represents a node that is already booted.

Because of this, it is recommended that clbootnodes be used for booting nodes which are known to be in a "first boot" condition.

When booting a node, clbootnodes will automatically answer the first boot questions. The questions are answered using the following information:
