Symptom
After you upgrade the MediaAgent to Commvault, the disk library runs out of space prematurely. An error similar to the following appears in the CVMA.log file:
28532 6f9c 12/05 12:08:45 ------ WORKER [ ] CVMAMagneticWorker.cpp:5479: Error while opening the mount path label [$[disk_library_location]\CV_MAGNETIC\MOUNTPATH_LABEL], error=0xECCC0002:{QiFile.cpp[CQiFile::Open(92)]} + {utfFsUtils.cpp[CQiUTFOSAPI::open(85)]/ErrNo.2.(No such file or directory)-Open failed, File=\\?\$[disk_library_location]\CV_MAGNETIC\MOUNTPATH_LABEL, OperationFlag=0x8000, PermissionMode=0x100}
Cause
The input file (mount path label file) is missing from the mount path. This prevents aged data from being pruned.
Resolution
You can create mount path label files using the workflow. For more information, see Predefined Workflow - Create Mount Path Labels.
