ClusterPack Tutorial

sysimage_register. You can see a list of registered images by executing:

The full path of the image must be given to clbootnodes:

Note:

After installing an image with clbootnodes -i, it may be necessary to wait several

minutes after clbootnodes returns before running compute_config as the

deamons may need time to start and stablize

Step 4 Invoke /opt/clusterpack/bin/compute_config on Management Server

This tool is the driver that installs and configures appropriate components on every Compute

ode. It is invoked with the "add node" option -a as follows:

% /opt/clusterpack/bin/compute_config -a <new_node_name>

This command configures the new node with the specified hostname to serve as a Compute Node

in the cluster.

The '-a' option can be repeated if more than one node needs to be added to the system.

For more information on the usage of compute_config, refer to the man pages.

% man compute_config

Step 5 Invoke /opt/clusterpack/bin/finalize_config on Management Server

Finalize and validate the addition of the new node to ClusterPack:

% /opt/clusterpack/bin/finalize_config

This step completes the configuration process, does verification checks on the Cluster

Management Software, and validates the addition of the new node.

1.6.2 Remove Node(s) from the Cluster

Compute Nodes are removed from ClusterPack by using the three stage process that is used for

installation:

Installation and configuration of the Management Server

Installation and configuration of the Compute Nodes

Verification of the Management Server and Compute Nodes

The steps in this section must be followed in the specified order to ensure that everything works
