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.
JES3 SUPPORT
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.
SUSPEND/RESUME
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.
FDRINSTANT
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.
