Case 1: TDEVN Spe
cified, DDSW = NO
All the relationships established with the copy target extents existing in the device specified by TDEVN
are withdrawn. The relationships established with the copy source extents existing in the specified
volume are not w
ithdrawn.
Below is an example of the command description for Case 1. This example requests the withdrawal of all
the
relationships established with the copy target extents existing in the device numbered 4203.
FCWITHDR TDEVN(X'4203')
Figure 45 Example: FCWITHDR Command Desc ription (C a s e 1)
By executing the command described above, the relationship established with the specified target,
Dataset 3, in the device num bered 4203 is withdrawn. The relationship established with Dataset 4 is not
withdrawn because it is the dataset specified as the source. In short, there are two relationships before
executing the command above, and after executing the command, there is only one relationship.
