ClusterPack V2.5 Release Note

Comprehensive Install Instructions

Step 13. Run compute_config on the Management Server

Background

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

Compute Node.

• Registers Compute Nodes with HP SIM on the Management Server

• Pushes agent components to all Compute Nodes

• Sets up each Compute Node as an NTP client, NIS client, and NFS client

• Starts necessary agents in each of the Compute Nodes

• Modifies configuration files on all Compute Nodes to enable auto-startup of

agents after reboots

• Allows for the configuration of additional networks with clnetworks

• Prints a PASS diagnostic message if all configuration steps are successful

clnetworks

Each Compute Node is known to the Management Server through the IP address

and specified to manager_config. These interfaces are collectively known as the

Cluster Network. This term can be somewhat confusing when a cluster consists of

both private nodes and public nodes. This is possible, for example, when an initial

set of Compute Nodes is created on a private network and then additional nodes

outside the private network are added using -a. The IP address of each Compute

Node known by the Management Server makes up the Cluster Network.

ClusterPack includes a utility to configure additional networks on all of the

Compute Nodes. These networks, like the Cluster Network, refer to a logical

collection of interfaces/IP addresses and not to a physical network. However, they

must share a common netmask. The concept of a network is defined as:

• A name (for reference only)

• A subset of the nodes in the cluster

• A network interface for each node in the subset

• An IP address for each interface

• A name extension that is added to the hostname of each machine and

associated with each host’s interface
