PowerHA can be used in conjunction with an IBM i hosting i environment to provide disaster recovery for a production partition. This is not a standard PowerHA cluster/IASP environment, but rather a full system replication solution used by some customers as a DR solution. In this environment, the full production partition including the operating system is hosted in a network storage space within an IASP on the host partition. That IASP is then replicated using PowerHA to a backup host partition. In the event of a failure of the production partition, the target IASP and NWSD can be varied on, and the production partition can be IPLed on the second system.
