Figure 56 shows an example of the DFSMSdss command for processing FlashCopy Mirror Version 2
dataset copy operation. In this example, the dataset on the volume numbered FCPY05 is copied to a
volume numbered FCPY06.
Figure 56 Example of DFSMSdss Command (COPY DS)
FlashCopy Mirror Version 2 allows you to establish up to 16 pairs simultaneously from a single copy
source extent.
DFSMSdss Copy Command Options
• COPYVOLID
COPYVOLID command option allows you to select whether you want to copy the ID label (VOLSER:
Volume Serial Number). When you specify 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
DUMPCONDITIONING command added by APAR OW45674 is specified, the VOLSER of the source
volume is copied to the backup tape or disk. In this case, there is no need of specifying COPYVOLID to
copy the volume label.
NOTE: COPYVOLID and DUMPCONDITIONING cannot be specified at the same time.
• DUMPCONDITIONING
DUMPCONDITIONING 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.
• FCNOCOPY
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.
• FASTERREPLICATION
See
Table 54 for the explanation of the available parameters of this command. When
FASTERREPLICATION is not specified, the copy operation will be performed in the same way when
PREFERRED is specified.
