2. 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 volume specified as the T-VOL back to online.
The following example shows another example of how the FCESTABL command is used. In this
example, the FCESTABL command specifies to establish a relationship to copy the data in the
source device numbered 4202 to the target device numbered 4203 by NOCOPY mode while
4203 is online.
Example 38 Example of the FCESTABL command (COPY mode)
FCESTABL SDEVN(X'4202') TDEVN(X'4203') MODE(NOCOPY) SETGTOCK (YES)
Establishing Compatible FlashCopy SE relationships by volumes using
DFSMSdss command
The DFSMSdss command used to process Compatible FlashCopy SE volume copy operation is
FCSETGTOK + FCNOCOPY.
DFSMSdss processes the COPY FULL command in a few seconds and establishes the Compatible
FlashCopy SE relationship simultaneously as it completes the processing. The completion of this
process is not reported to the user.
The following first example shows an example of the DFSMSdss command for processing
Compatible FlashCopy SE volume copy operation. The second example shows an example of the
COPY FULL Command (FCCGFREEZE).
If you execute the command as shown below, the entire data in a volume numbered FCPY05 is
copied to a volume numbered FCPY06.
Example 39 COPY FULL command
//COPY FULL JOB

//INSTIMG EXEC PGM=ADRDSSU
//SYSPRINT DD SYSOUT=*
//SYSUDUMP DD SYSOUT=V,OUTLIM=3000

Establishing Compatible FlashCopy SE relationships while suspending
Write Operations to S-VOLs
When you establish Compatible FlashCopy SE relationships with the FCESTABL command while
suspending the write operations to S-VOLs to keep the data consistency, the ACTION parameter
(see the following table) is available in addition to the parameters in Table 53 (page 91).
Table 53 Parameters for the FCESTABL command (Compatible FlashCopy SE / In case of suspending
write operations to S-VOLs)
DescriptionValueParameter
Suspend the write operations from the host to S-VOLs. Although if you establish a
relationship specifying extents, the ACTION parameter will suspend the write operation
to the whole volume.

The following example shows an example of how to use the FCESTABL command to suspend the
write operation to an S-VOL when you establish a Compatible FlashCopy SE relationship. In this
