This section describes the steps you take to setup High Availability Cluster Multi-Processing (HACMP) to work with HACWS.
Follow the instructions in the "Defining the cluster topology" chapter of the HACMP for AIX: Installation Guide to define the cluster environment. You must configure HACMP to use hardware address swapping in conjunction with IP address takeover on any service adapter belonging to the SP Ethernet network or whose name matches the host name of the primary control workstation.
The service adapter dutchess.xyz.com from the sample scenario, (see the |"Planning for a high availability control workstation" chapter |in RS/6000 SP: Planning, Volume 2, Control Workstation and Software Environment) falls into both categories. The "Planning TCP/IP networks" chapter of the HACMP for AIX: Planning Guide explains hardware address swapping.
As you define your cluster environment, you may find it helpful to read the following examples which reference the example configuration discussed in the |"Planning for a high availability control workstation" chapter |in RS/6000 SP: Planning, Volume 2, Control Workstation and Software Environment.
Follow the instructions in the HACMP for AIX: Installation Guide or the HACMP for AIX: Enhanced Scalability Installation and Administration Guide.
In the sample scenario discussed in RS/6000 SP: Planning, Volume 2, Control Workstation and Software Environment, the host names of the control workstations are dutchess.xyz.com and ulster.xyz.com. HACMP does not care whether you use the short or long host names, so use the short host names. The sample scenario short hostnames are dutchess and ulster. Follow the instructions in the HACMP for AIX: Installation Guide or the HACMP for AIX: Enhanced Scalability Installation and Administration Guide to define the cluster nodes to HACMP.
In the sample scenario discussed in RS/6000 SP: Planning, Volume 2, Control Workstation and Software Environment, the service address is dutchess.xyz.com. The node dutchess has the boot address dutchess_bt.xyz.com and the node ulster has the boot address ulster_bt.xyz.com. The screens in the following figures show how the sample scenario adapters would be defined to HACMP. Refer to these figures as you follow the instructions in the HACMP for AIX: Installation Guide to define the adapters to HACMP.

Follow the instructions in the "Configuring cluster resources" chapter of the HACMP for AIX: Installation Guide or the "Configuring an HACMP/ES cluster" chapter of the HACMP for AIX: Enhanced Scalability Installation and Administration Guide to configure the HACWS application server. Use the following definitions:
Follow the instructions in the "Configuring cluster resources" chapter of the HACMP for AIX: Installation Guide to define the resource group. If you are installing HACMP/ES, follow the instructions in the "Configuring an HACMP/ES cluster" chapter of the HACMP for AIX: Enhanced Scalability Installation and Administration Guide.
Use the following options:
Use the following options:
This field can contain multiple network interfaces. You may have to type them out in order to get the SMIT screen to accept them all. You must have at least one network interface name matching the host name of the primary control workstation.
Complete the rest of the instructions in the "Configuring cluster resources" chapter of the HACMP for AIX: Installation Guide. If you are installing HACMP/ES, finish the instructions in the "Configuring an HACMP/ES cluster" chapter of the HACMP for AIX: Enhanced Scalability Installation and Administration Guide.
Follow the instructions in the "Verifying the cluster topology" chapter of the HACMP for AIX: Installation Guide to verify the cluster and node environment.
