If a disaster occurs, you might have to restore Tivoli® Storage Manager with devices that are not included in the device configuration file.
If this occurs, you must update the device configuration files manually with information about the new devices. Whenever you define, update, or delete device information in the database, the device configuration file is automatically updated. This information includes definitions for device classes, libraries, drives, and servers.
Definitions for paths are included when SRCTYPE is set to SERVER.
Library volume location information is updated in the device configuration file whenever CHECKIN LIBVOLUME, CHECKOUT LIBVOLUME, and AUDIT LIBRARY commands are issued for SCSI libraries.
If an automated tape library is used at the recovery site, volume location information in comments (/*....*/) in the device configuration file must be modified. First, manually place the physical database backup volumes in the automated library and note the element numbers where you place them. Then manually edit the device configuration file to identify the locations of the database backup volumes so that the server can find them to restore the database.
For virtual volumes, the device configuration file stores the password (in encrypted form) for connecting to the remote server. If you regressed the server to an earlier point-in-time, this password might not match what the remote server expects. In this case, manually set the password in the device configuration file. Then ensure that the password on the remote server matches the password in the device configuration file.
