Non-Disruptive - The operating system, application jobs, online systems, and users will be unaware that FDRPAS is swapping disk volumes to new disk devices. When FDRPAS completes the swap of a disk, the volume resides completely on the new device, and the original device is no longer required. When all volumes on an old disk subsystem are moved to new locations with FDRPAS, the old subsystem can be powered off and disconnected.

24 x 7 Installations - have no window for major re-configurations and hardware changes. OS/390 hardware and software allows you to attach new disk subsystems (hardware) to your system and dynamically activate an updated I/O configuration to make them available. FDRPAS complements that capability by allowing you to move the data from existing volumes to this new hardware while those volumes are still in use.

Move terabytes of data - Even installations with maintenance windows do not have the time to move the terabytes residing in large shops. FDRPAS allows you to swap large number of volumes during normal business hours.

Versatility - FDRPAS can swap volumes in use on a single system image, as well as those attached to multiple systems or LPARs in a shared-DASD complex or sysplex, whether locally or remotely attached. Multiple volumes can be swapped concurrently.

I/O Load Balancing - When the I/O load in one or more disk subsystems is excessive, while other subsystems are underutilized, you can use FDRPAS to rearrange your disk volumes to equitably distribute the I/O load and improve performance.

Backup - create a point-in-time backup for FDRINSTANT™.

Monitoring - the progress of swapping can be monitored locally or remotely.
