ClusterPack V2.5 Release Note

Comprehensive Install Instructions

NOTE clbootnodes can only be used to boot nodes to the language

specification: English

The first time that HP-UX is booted after installation, it asks a series of questions:

• What language to use

• Hostname

• Time and Time zone settings

• Networking configuration

•Root password

Booting each node in a medium to large cluster can be a long and tedious task.

clbootnodes automates the processes to make it much faster and relatively free of

user interaction. It is also possible to boot only specified nodes using clbootnodes.

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.

• The utility could not determine the state of the console.

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. However, because

a user can leave the console in any state, it is not always possible to determine the

state of a console. 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:

• Language selection: All language selection options are set to English.
