Hi
Further explanation. Here is my dilemma in a nut shell: I have a z/Linux volume on a guest that does not have a z/OS VTOC. We typically use DFDSS on z/OS to back the z/Linux disks up and restore them at out DR site. Since this particular guest does not have z VTOC DFDSS cannot open it. So given this we decided to use DDR for this disk but the guests have the disk allocated so we are not able to attach the disk to the user that would be doing the DDR. So the only way I know to get this backed up is shutdown the guest and then attach the disk to the user doing the DDR. So I am assuming that if I do this that DDR will back up everything needed on this pack to do a good restore at the DR site. Are assumption good here and is there other ways to do this say without bringing the guest down?

It simply copies whatever is there. A very useful trait in many cases. Peter -----Original Message----- From: The IBM z/VM Operating System [mailto:[email protected]] On Behalf Of Martin, Terry R.

Also do you know if DDR cares rather there is a VTOC on a volume if it is used to backup the volume without a VTOC?
