LPAR to a test LPAR. We would quiesce the files as above. And we would also
make the SnapShot copy. But, this time, the volume serial number of the source
would be retained on the target. Because the target volume for a SNAP copy is
always in a DVCDN condition, the duplicate volume serial number would not
interfere with the production system. The target volumes would then be taken
away from the VSE production system through the use of the offline command.
The volumes would then be placed online to the test LPAR and then, using the
IDCAMS IMPORT CONNECT to access the UCAT, you can use the files in the test
LPAR. In this case, IDCAMS BACKUP could be used to back up the files.
