About AIX and IBM HACMP

This sub-book describes how to install Transfer CFT and configure using AIX with IBM HACMP. This topic lists prerequisites and provides an overview of the system.

Prerequisites

System:

  • AIX 5.3 and higher

Software:

  • HACMP 4.4.1
  • Transfer CFT

Preparing the environment

The test environment comprises two nodes: hacmp1 and hacmp2.

For the virtual IP address, we defined the virtual IP of the Transfer CFT server for HACMP on our DNS. It is also possible to declare the virtual IP on each node of the cluster, in the /etc/hosts file. For our tests, we added the following line to this file:

172.17.50.57  cft-ip

This virtual cft-ip address must be declared on all the cluster nodes (hacmp1 and hacmp2 for our tests). Use it for our Transfer CFT service.

Shared File Systems

On our cluster, the shared file system is /cft-vg. (group volume cftvg).

You can use several separate file systems to install the configuration, the scripts, the files to be sent, and the files to be received.

Setting up the Transfer CFT scripts for HACMP

The scripts cftstartFailover and cftstopFailover are copied to the shared filesystem:

  • cftstartFailover:This script creates a backup and recreates the logs and accounting files. It then restarts Transfer CFT.
  • cftstopFailover:This script tries a normal Transfer CFT stop procedure, then cleans the environment.

These scripts are available in the topic Transfer CFT Scripts of this document.

Transfer CFT installation

The process of installing Transfer CFT is the same as for installing Sun Cluster.
