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
