Data Access During Operating System or Hardware Outages z/OS DFSMS Introduction SC23-6851-00 |
|
DFSMS can provide you with access to your data even during operating system or hardware outages. For example, you can restore data from tapes when the operating system is not functional. You can also maintain access to critical data sets on DASD in case of device problems by allowing DFSMS to maintain dual copies of your key DASD volumes. |
