Innovation Data Processing, Little Falls, NJ, announces FDRPAS(“FDR Plug and Swap”) for the non-disruptive movement of OS/390 disk volumes from one disk device to another.

FDRPAS allows an OS/390 or z/OS installation to:

• Swap disk volumes from their current locations to new disk hardware

• Move disk volumes within the installation for load balancing

• Do this volume movement without interrupting any system activity

• Do this volume movement during normal system operations

• Swap shared DASD on all sharing systems simultaneously

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.

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

FDRPAS supports a wide variety of disk devices from hardware vendors including IBM, EMC, StorageTek, Amdahl, and Hitachi. It can swap disk volumes between disks of the same type from the same hardware vendor or different hardware vendors without any special software or hardware modifications.

Swap of a disk volume is very simple. An FDRPAS monitor job or task is started on each system that has access to the volumes to be swapped. Then a simple FDRPAS job or console command is issued to request that an online volume be swapped to an offline disk device. 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. FDRPAS will verify that the target device is offline to all sharing systems, to insure that an active volume cannot be accidentally overlaid.

For each requested volume, FDRPAS will copy all allocated tracks on the volume to the new disk device (for inactive data sets, only used tracks are copied), while simultaneously detecting all updates to the original device; updated tracks will be re-copied if necessary. The new device remains offline to OS/390 during the copy, so that the copied data is protected until the swap is complete.

Once the copy is completed, FDRPAS will swap the devices so that all I/O is now directed to the new device and the old device is no longer in use. The new device is placed online and the old device is offline. The old device will be modified so that OS/390 will no longer be able to vary it online. When the system is re-IPLed, the new device will automatically come online.

Only the source and target devices are accessed by FDRPAS. It does not use any additional communication between systems. It does not require TCP/IP, VTAM, a dataset on a third disk volume or a coupling facility.

Swapping of a volume can be terminated at any time before the final swap without affecting the original device or any applications using it.

After a successful swap, the now-offline original device can be used as a point-in-time backup of the volume, at the point of the final swap. When all volumes in an old disk subsystem have been swapped to new disks, the old subsystem can be disconnected and removed.

FDRPAS can swap any OS/390 or z/OS volume, except for volumes containing active page and swap data sets. This includes the SYSRES volume, other system volumes, application data volumes, CICS volumes, database volumes, TSO volumes, SMS-managed volumes and work volumes.

FDRPAS will be generally available in First Quarter 2001 in the USA and Second Quarter 2001 in other locations. Beta testing is currently in progress.

Swapping a disk volume to a new device or creating a point-in-time backup is very simple.

On a single system, issue a console command such as:

S PASPROC,PARM=’SWAP TYPE=FULL/MOUNT VOL=PROD01,SWAPUNIT=25C0’ 

//SWAP  EXEC  PGM=FDRPAS,REGION=0M 
//SYSPRINT  DD  SYSOUT=* 
//SYSIN  DD  * 
  SWAP TYPE=FULL,PACEDELAY=10 
  MOUNT VOL=PROD01,SWAPUNIT=25C0

On multiple systems, you simply start a FDRPAS monitor task for the potential FDRPAS target devices on each system with a console command, then issue the SWAP command on any system.

S PASPROC,PARM=’MONITOR TYPE=SWAP/MOUNT SWAPUNIT=(25C*,3*)’

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. FDRPAS will dynamically manage the copy process in response to system activity (e.g., copying inactive datasets before active datasets and pacing the copy I/O), to minimize its effect on the system.

By default, FDRPAS copies 15 tracks from the source to the target in each I/O. An FDRPAS SWAP will take about the same elapsed time as a normal full-volume disk-to-disk copy, unless there is a great deal of update activity on the volume being swapped.

POINT-IN-TIME BACKUPS

FDRPAS can also be used to create non-disruptive point-in-time backups of disk volumes, when used in conjunction with FDR InstantBackup, a feature of the FDR family of disk management software products.

The FDRPAS SWAPDUMP command can be used to start constantly updated images of one or more disk volumes, at some time before the backups are required. A single command to FDRPAS is then used to terminate the SWAPDUMP operation and create the offline point-in-time images of those volumes. FDR InstantBackup is used to backup those offline images.

ISPF MONITORING PANELS

FDRPAS ISPF panels allow you to initiate FDRPAS swaps, monitor their progress, change pacing values dynamically, and (if required) terminate swaps.

FDRPAS SAMPLE SWAP OUTPUT

The following sample output shows the swap of an volume shared by 3 systems. Applications were updating the volume on all of the systems. The swap takes place simultaneously on all 3 systems.
