IBM PowerHA SystemMirror V7.2 for AIX

IBM PowerHA SystemMirror V7.2 for AIX enables HA and DR.

It is an update of the V7 family of products. It uses the same clustering foundation as V7.1, which enables simpler migration support from V7.1.

PowerHA SystemMirror V7.2 for AIX offers following features and benefits:

• Saves you time and money by integrating IBM Power Enterprise Pools and Elastic Capacity on Demand as part of a PowerHA failover operation.
• Enables automation that eliminates the need for an operator to conduct manual steps to perform a live partition mobility (LPM) move or AIX Live Update.
• Automatically replaces failed repository disk.
• Includes nondisruptive upgrade of the PowerHA SystemMirror release.
• Performs automatic verification checks for AIX and PowerHA across all the nodes in the cluster, thereby eliminating operator effort and error.
• Includes quarantine policies for handling cluster splits, eliminating the potential for data corruption. Disk fencing and HMC-based active node shoot-downs to isolate the sick node.
• Enables tie breaker to be set up using an NFS server.
• Includes a wizard to configure GLVM (low cost mirroring) in a PowerHA cluster.
• Enables manual control for mirror resync operations in EMC SRDF deployments.

PowerHA SystemMirror is the IBM Power Systems strategic solution for HA and DR. Cluster Aware AIX was introduced with V7.1, making PowerHA an integrated extension of AIX.

V7.2 features capabilities that enhance economic value, providing greater automation and higher levels of resilience. PowerHA V7.2 makes the solution less expensive to acquire and less expensive to own by integrating Power Enterprise Pools and Elastic Capacity on Demand as a natural extension of failover operations. Greater degrees of automation are designed to minimize dependence on IT operational procedures and advanced capabilities such as nondisruptive upgrades.
