To update the current device mapping file

1. Find the latest external types file for your devices on the Symantec support Web site. The following is the address for the site:

   http://entsupport.symantec.com

   The files that you download are named similarly to the following files (x represents the NetBackup release, such as 7):

   Mappings_x_nnnnnn.ZIP

2. Download the file to the following location on the system that hosts the EMM server:

   • /usr/openv/var/global (UNIX)

   • install_path\netbackup\var\global (Windows)

3. Uncompress the file.

   It contains a Readme.txt and a device_mappings.txt file.

4. Update the EMM database with the new version of the device mapping file by using the following command (no command-line parameters are required):

   install_path\volmgr\bin\tpext

5. Stop and restart the NetBackup Device Manager.
