VALIDATION OF THE IDENTITY OF A REMOVABLE MEDIA VOLUME MOUNTED IN AN AUTOMATED DATA STORAGE LIBRARY

摘要

In an automated data storage library, procedures are implemented to ensure that a correct volume is mounted before data is written to or read from the volume. After a host requests access to a specified volume, the volume is retrieved and mounted in a storage drive. The drive then verifies the volume serial number (VolSer) to ensure that it matches the VolSer of the requested volume. If the two VolSers are the same, the host is notified that the identity has been verified and access is allowed. If the two VolSers are different, an error recovery procedure may be initiated. The VolSer may be read by the drive through electronic means, such as a cartridge memory reader or an RFID tag reader, thereby avoiding potential problems which may result from physically reading or scanning an external label affixed to the volume.
