If you have a static disk library that was created using a previous version of the Commvault software you may not be able to share the mount path. Use the MMConvertMagLibToStaticShared script found in the Installation_Directory/Base folder. You can execute the script from the command line using the following command:
qoperation execscript -sn MMConvertMagLibToStaticShared -si "LIBRARY NAME"
Where:
LIBRARY NAME is the name of the library in which the mount path is configured.
For more information on running QScripts, see Command Line Operations using QScripts.
