When the DFSMSdss com m a nd is executed, all datasets on the source volume are copied to the T-VOL
(see
Figure 10 on page 37). A volume area tha t is not allocated as a dataset is not copied.

Figure 10 C opying All Data sets Using the CO PYFULL Command ( Version 1)
Notes:
The following conditions cause the storage system to output the AD R935W message and end with
CC = 4 (co py operation is performed via the host):
The size of the T-VOL is larger than the S-VOL within the same CU image.
The emulation types of the S-VOLs and T-VOLs are different within the same CU image.
When the SSID boundary is 64-LDEV and you establish a relationship between two volumes that
have the same CU image but different SSIDs, you can copy data from the S-VOL to the T-VOL
by
the host program.
Releasing a Version 1 Relationship Using FCWITHDR
You need to use the FCWITHDR comm a nd of PPRC TSO to release a Version 1 relationship. The specied
volume m
ust have an established relationship.
When the SSID boundar y is 64-LDEV, the S-VOL a nd the T--VOL for Version 1 must be established in the
same CU image and SSID. When the S-VOL and the T-VOL are in different CUs or different SSIDs, delete
the
relationship from the ShadowImage for Mainframe’s Pair Operation window.
The following table shows the parameters you can use with the FCWITHDR command.

the number (device address) of the S-VOL on which you
want to
perform the FCWITHDR command.
TDEVN
Target device number.
Specify the number (device address) of the T-VOL on which you
want to perform the FCW ITHDR command.
Figure 11 on page 37 shows an example of the FCW ITHDR c om m a nd.
