FCWITHDR Comman d Desc ription (SDEVN and TDEVN Speciﬁed,

DDSW = NO, XTNTL

Speciﬁed) (Ca se 4C)

Case 5: SDEVN and TDEVN Speciﬁed, DDSW = YES

All the relationships established with the extents in the source or target device speciﬁed by SDEVN

are withdrawn.

If thedevicespeciﬁed by SDEVN is the source and if the relationships are set to the COPY mode, the

relationships are withdrawn after the backg round copy p rocess is completed.

If thedevicespeciﬁed by SDEVN is the source and if the relationships are set to the NOCOPY mode,

the

relationships are withdrawn af ter the copy operation mod e is changed to COPY mode and then the

background copy process is completed. If the device speciﬁed by SDEVN is the target, the relationships

are withdrawn immediately. The information on the device speciﬁed by TDEVN is ignored.

Below is an example of the command description for Case 5. When YES is selected for the DDSW

parameter, the parameter value for TDEVN is ignored. Therefore, the following two examples show

the

same content represented by a different description, both requesting the withdrawal of all the

relationships established with the device numbered 4202.

xample: FCWITHDR Command Description (SDEVN and TDEVN Speciﬁed,

DDSW = YES) (Case 5)

By executing the command described above, the relations established with Dataset 1 and Dataset

2 in the

dev

ice numbered 4202 are withdrawn. As a result, there will no longer be any relationships

establis

hed with the device numbered 4202 after executing this command.
