9. A popup screen should then indicate the Disk Library has been successfully created and on the main CommVault menu the device will appear as a Disk Library. Right click on the library (within the Storage Resources-Libraries folder) to display the Library Properties dialog. In our example, we are changing the library name on the General tab to something more meaningful (DiskLibrary16 to CommVaultShare1). Mount Paths tab A number of settings on this tab should also be edited. The Attribute, Prevent accidental deletion of data from mountpaths, must be unchecked to allow operation. The Allocate number of Writers value allows you to establish the maximum number of concurrent data protection operations on the disk library. HP recommends setting a specific number of writers per D2D NAS share dependent on the D2D Backup System. For example: the recommended setting is 12 for the HP D2D4312 Backup System. This value is set to ensure that the D2D NAS share does not exceed its maximum open file limit (see Appendix B). This setting is also dependent on the number of data streams set in the Storage Policy. 18 Discover the NAS CIFS share in CommVault
