![]() This function allows the DS8000 to quickly return a “format completed” status to the IBM i partition making the volumes available to the host. When adding disk units on an IBM i partition (either SYSBAS or IASP volumes), the DS8000 defaults to using an internal quick initialization. The HA/DR copy of the IASP is protected during the process because the PPRC relationship on the existing volumes continues while the new volumes are included in the PPRC relationship before they are added to the IASP. ![]() The process described is the fastest and least disruptive manner in which to add new volumes into an ICSM environment. ![]() This document outlines the preferred approach, which keeps the IASP available to the system while preserving the HA/DR copy. There are different ways of adding disk units into an existing configuration. When increasing the capacity of an existing IASP Copy Services Manager environment, you need to plan carefully to ensure the current environment is protected throughout the entire process. *NOTE - Refer to attachments at the bottom if using toolkit for Multi-Target Replication with CSM Adding IASP disk units to an existing DS8000 IASP Copy Services Manager (ICSM) environment ![]()
