ClusterPack Tutorial

When booting a node, clbootnodes will answer the first boot questions rather than having to answer the
m
manually. The questions are answered using the following information:
z
Language selection: All language selection options are set to English.
z
Keyboard selection: The keyboard selection is US English
z
Timezone: The time zone information is determined based on the setting of the
Management Server
z
Time: The current time is accepted. The time will later be synchronized to the
Management Server using NTP.
z
Networking: The LAN card specified will be configured to the IP address specified to
manager_config.
z
Hostname: The hostname will be set to the name specified through manager_config.
z
Root password: The root password will be queried before the nodes are booted.
Overview
Use the clbootnodes program to power up all Compute Nodes that have a connected MP that you specifi
e
the previous step. It will answer the first boot questions for all nodes automatically.
Provide the following information to the clbootnodes program:
z
Language to use,
z
Host name,
z
Time and time zone settings,
z
Network configuration,
z
Root password.
Details
To run clbootnodes, use the following command:
%
/opt/clusterpack/bin/clbootnodes
Before booting the nodes, clbootnodes will ask you for the root password to set on the Compute Nodes a
n
the LAN card to configure for networking for each host. The LAN card choice for each host will be set t
o
IP address specified earlier via manager_config.
To boot the node using DHCP, invoke the program as follows:
% /opt/clusterpack/bin/clbootnodes <list_of_node_names>
You can omit the argument list, in which all nodes in the cluster will be processed. The IP address used
w
b
e the one that you provided previously. The program will interact with you to obtain the name of the L
A
card to use.
