USING ICKDSF to release Compatible FlashCopy V2 relationships

DDNAME or DNAME

JCL statement

Specifies the JCL statement identifying the volume. If the OS of the host server is z/OS^®, this parameter or the UNITADDRESS parameter is required.

SYSNAME

SYSNAME

Specifies the SYSNAME in the ASSGN system control statement. If the OS of the host server is VSE, this parameter is required.

UNITADDRESS, UNITADDR, or UNIT

Source device number

Specifies the device number (device address) of the S-VOL on which you want to perform the FLASHCPY WITHDRAW command. If the OS of the host server is z/OS^®, this parameter or the DDNAME parameter is required.

TARGETVOL or TGTVOL

CU number LDEV number Target device number

Specifies the CU number, LDEV number, and device number (device address) of the T-VOL on which you want to perform the FLASHCPY WITHDRAW command. This parameter is required. The Target device number is required only in certain situations. See the IBM^® Device Support Facilities (ICKDSF) manual for more information.

MODE

COPY

Executes a background copy operation for all source relationships existing for the volume specified in the DDNAME, SYSNAME, or UNITADDRESS parameter. If YES is specified for CHANGERECORDING when creating the relationship, the relationship will be maintained after the background copying operation is completed. If NO or nothing is specified for CHANGERECORDING when creating the relationship, the relationship will be withdrawn after the background copying operation completes.

NOCOPY

Deletes all source relationships for the specified source volume and specified target volume.

NOCOPY is the default setting.

ALL

Performs the same actions as MODE(COPY) and also withdraws all target relations on the addressed volume.

RESETTGTWRTINHIBIT, RESETTGTWRTINHB, or RTWI

No value required

Permits write operations to the T-VOL. The relationship is not deleted.

SOURCEVOL or SRCVOL

CU number

LDEV number

SSID

Serial number

Source device number

This parameter is required only when the Compatible FlashCopy^® V2 source volume is a PPRC secondary volume of the device identified by the DDNAME, SYSNAME, or UNITADDRESS parameter. It specifies the CU number, LDEV number, and SSID of the Compatible FlashCopy^® V2 source volume, the serial number of the storage system containing the Compatible FlashCopy^® V2 source volume, and the device number (device address) of the source volume. The device number is required only in specific situations. See the IBM^® Device Support Facilities (ICKDSF) manual.

FORCE

YES

Releases the relationship established by the Preserve Mirror FlashCopy^® function without executing the background copy operation. Releases the relationship defined to the copy target.

NO

Releases the relationship established by the Preserve Mirror FlashCopy^® function after the background copy operation completes.

NO is the default setting.

RELATSPACE*

No value required

If the T-VOL is a TSE-VOL, the physical capacity of the allocated TSE-VOL is released.

*Valid only for Compatible FlashCopy^® SE.
