SUMMARY OF MODIFICATIONS FOR VERSION 5.4 LEVEL 11
PARALLEL ACCESS VOLUME(PAV) SUPPORT
Parallel Access Volumes are now supported by FDRPAS. It supports PAVs on the IBM 2105 ESS (Shark) and also on EMC Symmetrix systems in 2105 emulation. PAVs will be disabled during the swap process. If you are swapping from one device with PAVs to another device with PAVs, they will be re-enabled after the swap. However, if you are swapping from a non-PAV device to a PAV device, or vice versa, an IBM limitation forces PAVs to remain disabled on the PAV device until the next IPL.
EMC CONSISTENCY GROUP SUPPORT
FDRPAS now supports EMC Consistency Groups. However, to complete the support you must install V4.0.0 or higher of the EMC Consistency Group Software. FDRPAS will allow a volume in a consistency group to be swapped only to another
volume in the same consistency group.
CONCURRENT COPY SUPPORT
If FDRPAS detects that a concurrent copy session is active and doing I/O on a source volume, it will delay completing the swap until no concurrent copy I/O has been detected for 2 minutes.
FDRPAS can now be executed under JES3. However, it can only swap volumes on devices which are not managed by JES3.
INDEXED VTOC REBUILD
FDRPAS includes a utility function which allows you to build an indexed VTOC (VTOCIX) or rebuild a disabled VTOCIX on a shared DASD volume while it is online to multiple systems. This is equivalent to the BUILDIX function of the IBM ICKDSF utility, except that ICKDSF requires that you vary the volume offline to every system except one before you execute BUILDIX. The SWAPBUILDIX function of FDRPAS uses FDRPAS communication and co-ordination techniques to allow the VTOCIX to be built while online to all sharing systems.
Through the FDRPAS ISPF panels, it is now possible to suspend an active swap, and resume it later. When suspended, FDRPAS will not copy any tracks from the source volume to the target device, but it will continue to monitor updates on the source volume. When resumed, copying of original and updated tracks begins again.
Come join us at the IBM Storage and Storage Networking Symposium on August 20-24, 2001 in Las Vegas, NV.
Join an informative discussion on the ability of INNOVATION's technology to meet your demands for non-stop processing. Attend the presentation on "Employing FDRPAS Solutions for Non-Disruptive Hardware Installation", given by Storage Management Architect, Bruce Black.
The presentation will be in the Capri Room, on Tuesday, August 21 at 4:10pm.

FDRPAS (FDR Plug and Swap)
"Non-Disruptive" disk volume relocation provides continuos 24x7x365 availability, even as you install more storage capacity, upgrade existing hardware, move volumes for load balancing and eliminate hot spots on the "fly", so business operations continue non-stop.
Employing IBM FlashCopy, StorageTek SnapShot Copy, EMC TimeFinder and Hitachi ShadowImage provide e-Business protection with INSTANT disk backup/restore and non-disruptive tape backup's.
