Parameter
Value
Description
COPYVOLID
N/A
The COPYVOLID command option allows you to select
whether you want to copy the ID label (VOLSER). When
you specify COPYVOLID, the ID label of the volume set as
thesourceiscopiedtothe volume that is setasthe target.
When the
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 the
DUMPCONDITIONING command added by APAR
OW456 74 is specified,the VOLSER of thesourcevolume
is
copied to the backup tape or disk. In this case, there is
no need to specify COPYVOLID to copy the volume label.
DUMPCONDITIONING
N/A
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
N/A
This command sets the copy operation mode to NOCOPY
mode. When this comm and is specified, the background
copying process is omitted from the copy operation.

relationships in order to maintain the 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.
For information about the FCWITHDR command, see
Releasing a Version 2 Relationship Using FCWITHDR on
page 83. For details about the process of suspending and
resuming the write operation from the host to the S-VOLs,
see Using Consistency Groups for Dataset Copies that
Span Volumes on page 46.
