Establishing Compatible FlashCopy relationships by volumes using DFSMSdss
command
The DFSMSdss command used to process Compatible FlashCopy volume copy operation is COPY
FULL. The following table shows the parameters you can use with the DFSMSdss command when
you establish Compatible FlashCopy relationships by volumes.
Table 22 Parameters for the DFSMSdss command (Volume Copying)
DescriptionValueParameter
The COPYVOLID command option allows you to select whether you
want to copy the ID label (VOLSER). When you specify COPYVOLID,
N/ACOPYVOLID *1
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, it is not necessary
to specify COPYVOLID to copy the volume label.
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.
N/ADUMPCONDITIONING *1
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/AFCNOCOPY
The relationship made by NOCOPY mode is copied in the
background. When all the data are copied, the relationship is released
automatically.
N/AFCNOCOPYTOCOPY
Executes Compatible FlashCopy copy operation as a priority. If
Compatible FlashCopy cannot be used, executes Concurrent Copy
or copy operation via the host.
PREFERREDFASTREPLICATION
When FASTREPLICATION is not specified, the copy operation will be
performed in the same way when PREFERRED is specified.
Executes Compatible FlashCopy copy operation unconditionally. If
Compatible FlashCopy cannot be used, reports error.
REQUIRED
Does not execute Compatible FlashCopy copy operation.NONE
This option is for temporarily suspending the write operation from the
host to the S-VOLs when you establish relationships to maintain the
N/AFCCGFREEZE
consistency of data. To resume the write operation from the host to
the S-VOLs, use the DFSMSdss CGCREATE command or the TSO
FCWITHDR command.
To use the Incremental FlashCopy function, use FCINCREMENTAL.
For details about the Incremental FlashCopy function, see the “Reverse
Restore function” (page 12).
N/AFCINCREMENTAL
When FCINCREMENTAL is specified, a relationship covering the
entire volume is created. This relationship is maintained after the
background copying process is completed. When FCINCREMENTAL
is specified, the following additional functionality becomes available.
• Manage the differential data between the S-VOL and the T-VOL.
• When you re-execute the COPY command, only the differential
data will be copied to the T-VOL.
