From the CommCell Browser, expand Storage Resources > Libraries > Library.
-
Right-click the mount path that you no longer want to use, and then click Properties.
-
From the Allocation Policy tab, click and enable the Disable mount path for new data option.

Retiring a Mount Path
When you retire a mount path, the mount path will not be used for subsequent write operations. However, you can perform restores (read operations) on the data available in the mount path.
To retire a mount path, disable the write operations on a mount path for any new data. For instructions, see Disabling Write Operations on a Mount Path.
Note
-
Depending on the retention criteria set on the storage policy copy, the data in the mount path will be pruned when the data aging operation is run.
-
When all the data in the mount path is completely pruned, the mount path can be deleted.
-
Important: For storage policies with deduplication, you can delete a mount path only when all jobs associated with the DDB are pruned. This is because the jobs managed by the DDB might have data on other mount paths that still refer to unique data blocks on this mount path. Therefore, deletion of a mount path is not allowed until the DDB has no more valid jobs.
To determine whether the mount path has valid data, see View the Contents of a Mount Path.
To delete a mount path, see Delete a Mount Path.
