Thanks Mike and Aria for your input. We did plan on having everything shutdown and are going disk to disk.

Thus, ensure that the target backup volumes are not being used by any system when being backed up. Best practice: shutdown the z/VM guest servers and even the z/VM system (since presumably it is being moved, too) during the backup. FDR can copy directly from disk to disk (presuming that the architecture is the same). Saves tape mounts and downtime. FDR has the capability to re-label the "from" volume when the copy has completed. Handy to prevent accidental usage when you are IPLing from the new DASD. All the data is on the old volumes, only the label has been changed to protect the innocent. ;-) Mike Walter Hewitt Associates Any opinions expressed herein are mine alone and do not necessarily represent the opinions or policies of Hewitt Associates.

We are going to move our z/VM 5.3 and Red Hat Linux 5.2 DASD volumes from address range 7xxx to 8xxx using FDR full volume physical backups/restores and keep the same volume labels. We will modify the system config file to vary online the 8xxx range and IPL off the new 8xxx RES pack. Is there anything else we need to change or be aware of? We are using EMC DASD but I don?t think that matters. FDR runs on z/OS. Thanks!
