## 17.3.2 Suggested configurations of BRMS 

Policies 

QBRM and QUSRBRM 

Defines how BRMS operations are processed. There are different types of policies, which include system policy, backup policy, recovery policy, media policy, and move policy. A policy determines how data is to be processed. 

These IBM i libraries contain BRMS-related objects and management information. 

VTL versus physical tape drives:  Configuration of BRMS for ProtecTIER virtual tape devices is no different from configuration for physical tape devices. Relevant BRMS version guidelines and steps to configure BRMS tape devices are available in the IBM BRMS product information section at the following web page:

This section focuses on the suggested BRMS configurations that are relevant to ProtecTIER virtual tape devices. The following list includes some guidelines: 

GLYPH<SM590000> Use STRSST  to reset the tape adapter that is attached to the ProtecTIER node to recognize newly created virtual tape devices in ProtecTIER system. 

GLYPH<SM590000> The ProtecTIER VTL takes the next available TAPMLBxx name by default. Rename it to match the name that you used in ProtecTIER Manager to keep your environment orderly. 

GLYPH<SM590000> The ProtecTIER product emulates LTO3 tape devices. When you define the BRMS media class in a ProtecTIER environment, create a separate media class for virtual LTO3 volumes from the media class for physical LTO3 volumes. Use a *ULTRIUM3 density. 

Tip:  You can make the virtual LTO3 cartridges any size you want, but not the LTO3 size. The cartridges’ performance matches whatever your ProtecTIER configuration supports, and is not tied to LTO3 speed. 

GLYPH<SM590000> Add the virtual cartridges in to BRMS by running ADDMLMBRM  command and be sure to initialize them to reflect the virtual cartridge’s actual label (bar code). Use the actual command rather than navigating there from the WRKMLMBRM  menu. 

GLYPH<SM590000> To choose your replication destination with ProtecTIER Manager, complete the following steps: 

– If you choose a remote VTL as a destination, configure the move policy for the selected media so that the media can be moved out from the local VTL to the shelf after a save operation. The replica cartridges can then be moved to a remote VTL and be accessible in remote IBM i. 

– Do not configure a move policy if you want the media to stay in the library after save operations. You can perform a manual move when you want to access it from a remote site.
