Mainframe Enablers TimeFinder SnapVX and zDP 8.5 Product Guide

Determines whether the source device is to overwrite data on an existing target device.

If the existing device contains user data and you do not specify this parameter, the snap operation terminates. A volume with no user data is defined as one with only a VTOC, a VTOC index, and a VVDS.

If you specify YES and the target volume is not empty, old data on that volume are overwritten. Catalog entries for any datasets existing on the target volume may become invalid.

The REPLACE parameter can be specified on the GLOBAL and LINK command. It has a matching site option, &REPLACE.

The REPLACE parameter establishes the REPLACE value for all operations.

The REPLACE parameter only applies to locally addressable volumes. REPLACE is ignored if you specify it on actions with the SYMDV#, LOCAL, or REMOTE parameters. The REPLACE parameter is also ignored when you specify volumes by GNS group.

The REPLACE parameter is valid only with the TARGET parameter.

For information about using REPLACE with the REUSE parameter, see the TimeFinder/Clone Mainframe Snap Facility Product Guide.
