the UNITADDRESS parameter.
2. Specify SYSNAME of the ASSGN system control statement in the SYSNAME parameter if the
OS of the host server is VSE.

Example 10 FLASHCPY WITHDRAW command description
FLASHCPY WITHDRAW UNIT(X'7000') TARGETVOL(X'00',X'01',7001) MODE(NOCOPY)
NOTE: When the FLASHCPY WITHDRAW command is executed, all of the dataset
relationships existing in the specified volume will be withdrawn.
The FLASHCPY WITHDRAW command and the applicable combinations are predetermined. If you
specify any other parameter than the predetermined combinations, the FLASHCPY WITHDRAW
command is normally ended without executing any process.
The following table describes the parameters and the applicable combinations of the FLASHCPY
WITHDRAW
command. See the following table and specify any other necessary parameters.

Using ANTRQST Macro to release relationships
The FCWITHDRAW command can be used just as Compatible FlashCopy. However, DDSW=YES
cannot be specified. By specifying the SPACEREL=YES parameter, the allocated area of TSE-VOL
can be withdrawn.
Using z/VM CP to release relationships
The FLASHCOPY WITHDRAW command of z/VM CP can be used to release relationships. By
specifying the RELEASE parameter, the allocated area of a TSE-VOL can be released.
Viewing TSE-VOL or pool information using LISTDATA
The LISTDATA command can be used to display information of a TSE-VOL or a pool in the storage
system. The pool information here means the pool information for Thin Provisioning Z. The other
pool information is not displayed.
The following table shows the LISTDATA command parameters:
