*Valid in Compatible FlashCopy SE.
To perform volume copying:
1.
Set the T-VOL to offline.
2. Without specifying the EXTENTS and XTNTLST parameters, execute the FCESTABL command.
3. Change the VOLSER of the T-VOL.
When VTOC is copied, the VOLSER of the S-VOL and the T-VOL will become the same. This
step must be performed before setting the T-VOL back to online.
4. Set the T-VOL back to online.
The following example shows another way that the FCESTABL command is used. In this example,
the FCESTABL command specifies that the data in the source device numbered 4202 is to be
copied to target device numbered 4203 by COPY mode while 4203 is online. Example of the
FCESTABL command (COPY mode):
FCESTABL SDEVN(X'4202') TDEVN(X'4203') MODE(COPY) ONLINTGT (YES)
Using DFMSdss to establish Compatible FlashCopy relationships by volumes
COPY FULL is the DFSMSdss command that is used to process the Compatible FlashCopy volume

The COPYVOLID command option enables you to select whether you
want to copy the ID label (VOLSER). When you specify COPYVOLID, N/A COPYVOLID

the ID label of the volume set as the source is copied to the volume set
as the target. When COPYVOLID command is executed, the volume
used as the target is set to offline automatically.
The COPYVOLID command had to be specified for volumes controlled
by SMS. However, when DUMPCONDITIONINO command added by
APAR OW45674 is specified, the VOLSER of the source volume is
copied to the backup tape or disk. In this case, it is not necessary to
specify COPYVOLID to copy the volume label.
DUMPCONDITIONINO is used when you want to specify that the
purpose of the copy operation is to create a backup copy and not for
using the copied volume for application. N/A DUMPCONDITIONINO

This command sets the copy operation mode to NOCOPY mode. When
this command is specified, the background copying process is omitted
from the copy operation. N/A FCNOCOPY
The relationship made by NOCOPY mode is copied in the background.
When all the data are copied, the relationship is released automatically. N/A FCNOCOPYTOCOPY
