1 Changing Physical Disk Storage in IBM DB2 pureScale: A Practical Example This IBM Redbooks® Analytics Support web doc introduces a reference procedure and related  considerations for storage migration that is based on a real-life test example. Database and system  administrators can use this document as a reference when performing a storage migration in DB2  pureScale. This document applies to DB2 pureScale V9.8, V10.1, V10.5, and V11. Database administrators, operating system administrators, and system administrators working with DB2  pureScale in different capacities must understand how to upgrade the system and manage the changes  that are required for the upgrade effectively by performing the correct steps. Like any component in an IT infrastructure, DB2 pureScale eventually might require a migration to meet  the demands of upgraded hardware and software. IBM® DB2® pureScale® is a feature that provides continuous availability to multiple active servers that  share a common set of disk storage subsystems. This feature includes multiple components, such as IBM  Tivoli® System Automation (TSA) for high availability (HA) and General Parallel File System (IBM  GPFS™) for clustered file systems.  ® Changing Physical Disk Storage in IBM DB2  pureScale: A Practical Example
