IBM SG24-5131-00 manual Networks, Network Name, Network Attribute

The following diagram shows a cluster consisting of two nodes and a client. A single public network connects the nodes and the client, and the nodes are linked point-to-point by a private high-speed SOCC connection that provides an alternate path for cluster and lock traffic should the public network fail.

2.4.3.2 Networks

Networks in an HACMP cluster are identified by name and attribute.

Network Name

The network name is a symbolic value that identifies a network in an HACMP for AIX environment. Cluster processes use this information to determine which adapters are connected to the same physical network. In most cases, the network name is arbitrary, and it must be used consistently. If several adapters share the same physical network, make sure that you use the same network name when defining these adapters.

Network Attribute

A TCP/IP network’s attribute is either public or private.

Public A public network connects from two to 32 nodes and allows clients to monitor or access cluster nodes. Ethernet, Token-Ring, FDDI, and
