Restoring the Minidisk

To restore a minidisk that was backed up in a physical format, follow these steps:

  1. On the file selection screen or the Select Version of Minidisk or Directory to Restore screen, type r in the Req column next to the ** Non-CMS ** descriptor.

    CA VM:Backup displays the Restore From a Physical Backup screen. CA VM:Backup also displays this screen if you select the option to restore the latest version of an entire minidisk from the Select Minidisk or Directory From Which to Restore screen and the minidisk was backed up in a physical format. However, in this case, the ** Non-CMS ** descriptor is not displayed.

  2. By default, the Minidisk field contains the virtual address of the minidisk you selected to restore. Type the virtual address of the target minidisk in the Minidisk field. You can only restore to a minidisk that belongs to you.

    When you restore from a physical backup, you must restore to a minidisk. Minidisks backed up in physical format cannot be restored to a virtual reader or directory. The minidisk to which you restore must be of the same DASD type--that is, CKD or FBA--as the minidisk from which it was backed up. In addition, for CKD devices, the minidisks must be of the same type and class. Data backed up from a 3380 must be restored to a 3380 and data backed up from a 3390 must be restored to a 3390.

  3. Enter your response to the following question:

    Restore the entire minidisk?

    By default (NO), CA VM:Backup does not restore the entire minidisk. If you want to restore the entire minidisk, type yes.

  4. If you accepted the default (NO) because you do not want to restore the entire minidisk, you must specify the portions of the minidisk that you want restored.

    If you are restoring data that was backed up from CKD DASD, you must specify the cylinders and tracks to be restored. Type the physical ranges in the From and To columns. If you are restoring only one cylinder or track, identify that cylinder or track in the From column and leave the To column blank.

    If you are restoring data that was backed up from FBA DASD, you must specify the blocks to be restored. Type the physical ranges in the From and To columns. If you are restoring only one block, identify that block in the From column and leave the To column blank.

  5. Press ENTER to submit your request.
