NetBackup uses a file to determine which protocols and settings to use to communicate with storage devices. NetBackup also uses the file during device discovery and configuration.
In some cases, you can add support for new or upgraded devices without waiting for a release update from Symantec. To do so, download the current device mapping file from the Symantec support Web site and configure NetBackup to use that file. Refer to the README file that is supplied with the device mapping file for additional instructions.
