The IBM® HyperSwap® feature in IBM PowerHA® SystemMirror® provides continuous storage availability in a multisite PowerHA cluster. It gives the advantage of planned and unplanned maintenance and migration of storage. To achieve HyperSwap configuration across sites, administrators need to configure Peer-to-Peer Remote Copy (PPRC) Metro Mirror between pairs and need to enable the HyperSwap feature for each of the disks. This involves collecting the logical unit number (LUN) and logical subsystem (LSS) information of the shared disks from the cluster nodes, and this is a time-consuming process. This article describes the scripts that can perform the HyperSwap configuration automatically.
