This allows a 24x7 installation, with no window for major re-configurations and hardware changes, to install and activate new disk hardware. It can swap disk volumes between disks from the same hardware vendor or different hardware vendors without any special software or hardware modifications. The swap of a volume can be initiated on any system in the complex, and the other systems will automatically join in the swap operation. Multiple volumes can be swapped concurrently. The swap is accomplished with minimal impact on the performance of applications using the volumes being swapped.
Applications continue to execute, unaware that the data movement is occurring or has completed.
Swapping of a volume can be terminated at any time before the final swap without affecting the original device. When all volumes in an old disk subsystem have been swapped to new disks, the old subsystem can be disconnected and removed.
