NOTE: For IBM FlashCopy and PPRC, you can create a PPRC pair that includes a volume that functions as
both a FlashCopy T-VOL and a PPRC P-VOL (primary volume), and PPRC pair that includes a volume that
functions as both a FlashCopy T-VOL and a PPRC S-VOL (secondary volume).
Using ShadowImage - FlashCopy Host Commands
ShadowImage - FlashCopy supports both DFSMSdss commands and TSO PPRC commands to perform
ShadowImage - FlashCopy operations from the zSeries and S/390 host system.
Before you use ShadowImage - FlashCopy, you must take the following steps:
1. Install the SI390 feature and software.
2. Install the ShadowImage - FlashCopy feature and software.
3. Change the corresponding devices offline to the host, and then change the devices online to the host
again. This ensures that you have the latest device information before performing ShadowImage -
FlashCopy operations. This offline/online operation is required just once.
ShadowImage - FlashCopy does not support the REMOVEFCPY parameter of ICKDSF CONTROL
command. To delete the relationship of all the ShadowImage - FlashCopy pairs established in the disk
array, use the SI390 main window.
DFSMSdss Command Support
ShadowImage - FlashCopy can be used by the COPYFULL command (description) through the DFSMS dss
commands. DFSMS dss will automatically choose the fastest solution. The COPYFULL command completes
within a few seconds and the ShadowImage - FlashCopy pair is established at once. ShadowImage -
FlashCopy data is copied in the background and the completion of copy is not reported to the user. The
following shows an example of the DFSMSdss commands.
ShadowImage - FlashCopy can establish a relationship for one volume pair at a time. When
ShadowImage - FlashCopy copy is requested for a volume pair in the F-Copy status, DFSMSdss identifies
the request as an SI390 copy request through the host and performs SI390 copy operations.
The COPYVOID option is used to copy the volume serial number (VOLSER). If the COPYVOID option is
specified, the volume serial number is copied to the T-VOL and the T-VOL becomes offline automatically.
This COPYVOID option was necessary for SMS-managed volumes until the DUMPCONDITIONING
parameter was added to DFSMSdss with APAR OW 45674. If the DUMPCONDITIONING parameter is
specified, there is no need to copy the volume serial number for SMS-managed volumes.
When the DFSMSdss command is executed, all datasets on the source volume are copied to the T-VOL.
Volume area that is not allocated as a dataset is not copied.

NOTE: You cannot specify both the COPYVOID option and DUMPCONDITIONING parameter at the
same time.
