The FLASHCPY WITHDRAW command usage defines specific combinations of parameters that are allowed. If you specify a parameter combination that is not allowed, the FLASHCPY WITHDRAW command terminates normally without performing any action.

The following table shows the FLASHCPY WITHDRAW parameters and applicable combinations.

Table. Parameters of FLASHCPY WITHDRAW command and applicable combinations
Parameter				Background copying
DDNAME, SYSNAME, UNITADDRESS	TARGETVOL	MODE	Executed	Relationship after completion
S-VOL	T-VOL or some other volume	COPY	Yes	Maintained when CHANGERECORDING = YES Released when CHANGERECORDING = NO
S-VOL	T-VOL	NOCOPY or not specified	No	Released
S-VOL	T-VOL or some other volume	ALL	Yes	Maintained when CHANGERECORDING = YES Released when CHANGERECORDING = NO
T-VOL	S-VOL or some other volume	ALL	No	Released

If the host is running z/OS^®, do one of the following:
- Specify the name on the JCL DD statement that defines the source volume in the DDNAME parameter.
- Specify the S-VOL device number of the relationship that you want to delete for the UNITADDRESS parameter.
If the host is running VSE, specify the SYSNAME of the ASSGN system control statement in the SYSNAME parameter.
In the TARGETVOL parameter, specify the CU number, LDEV number, and device number (if required) of the T-VOL.
As shown in the following table, specify any other necessary parameters and execute the FLASHCPY WITHDRAW command as shown in the following example:
FLASHCPY WITHDRAW UNIT(X'7000') TARGETVOL(X'00',X'01',7001) MODE(COPY)

ICKDSF supports only the creation of full volume relationships. However, the FLASHCPY WITHDRAW command causes both full volume and dataset (for example, extent) relationships to be withdrawn.
