For more information, see “Inserting virtual volumes” on page 552. 

To increase the size of the RMM CDS, you must quiesce RMM activities, back up the CDS, and then, reallocate a new CDS with a larger size and restore the CDS from the backup copy. To more information about calculating the correct size of the RMM CDS, see z/OS DFSMSrmm Implementation and Customization Guide , SC23-6874. 

Consider the use of VSAM extended format in your CDS. Extended format and Multivolume support almost any growth rate in the Configuration data set. 

Other TMSs, such as BrightStor, CA-1 Tape Management Copycat Utility (BrightStor CA-1 Copycat), and BrightStor CA-Dynam/TLMS Tape Management Copycat Utility (BrightStor CA-Dynam/TLMS Copycat) must reformat their database to add more volumes. Therefore, they must stop to define more cartridges. 

Also, some TMSs do not enable the specification of tape volumes with alphanumeric characters or require user modifications to do so. For more information, see the corresponding product documentation. 

In RMM and the other TMSs, the virtual volumes do not have to be initialized. The first time that a VOLSER is used, TS7700 marks the virtual volume with VOL1, HDR1, and a tape mark, as though it was done by EDGINERS or IEHINITT. 

## 8.7 IBM Spectrum Protect 

IBM Spectrumfi Protect (Tivoli Storage Manager family) provides backup, snapshot, archive, recovery, space management, bare machine recovery, and disaster recovery capabilities. Throughout this publication, the Tivoli Storage Manager name is referenced. IBM Tivoli Storage Manager, such as DFSMShsm, can automatically fill a native 3592 cartridge. It can use the tape up to EOV, independent of the media type. 

Released in 2009, Tivoli Storage Manager 6.1 did not include Tivoli Storage Manager Server support for z/OS. IBM Tivoli Storage Manager for z/OS Media V6.3 and IBM Tivoli Storage Manager for z/OS Media Extended Edition V6.3 are replacement products for Tivoli Storage Manager V5.5 and Tivoli Storage Manager Extended Edition for z/OS V5.5, with new functions available in Tivoli Storage Manager V6, while maintaining the ability to access Fibre Channel connection (FICON)-attached storage on a z/OS system. 

Introduced with Version 6.3, IBM Tivoli Storage Manager for z/OS Media and IBM Tivoli Storage Manager for z/OS Media Extended Edition enable IBM Tivoli Storage Manager V6.3 servers that are running on IBM AIX and Linux on z Systems to access various FICON-attached tape libraries on z/OS, including the TS7700 family. 

Tip:  Beginning with Version 7.1.3, IBM Tivoli Storage Manager is now IBM Spectrum Protect. Some applications, such as the software fulfillment systems and IBM License Metric Tool, use the new product name. However, the software and its product documentation continue to use the Tivoli Storage Manager product name. For more information about the rebranding transition, see this IBM Support web page. 

For more information about the current Tivoli Storage Manager supported levels for Linux on z Systems, see IBM Knowledge Center.
