## Logical volume ranges or insert volumes connected to defined ranges 

On the MI window (see Figure I-17), insert the number of logical volumes that fits your initial need for PROD and TEST. The example shows how to insert 1000 logical volumes for the TEST partition. Normally, you define the inserted volume size to be 800 MB (ECCST). When used on z/OS, the assignment of DC defines the maximum volume size, which is 800 MB or 6000 MB in the case study.

## User Management on the Management Interface 

Depending on your requirements, you can define roles and rules for the users that use the MI to prevent unauthorized access to data and to set user privileges. For more information, see 9.3.9, “The Access icon” on page 463. 

## Verification of changes 

After setting the definitions, evaluate your setup against the one shown in Figure I-18 on page 939. If you attempt to access volumes from the other host, and SDAC is used, your job fails with this message: 

CBR4175I VOLUME volser  LIBRARY libname  ACCESS GROUP DENIES MOUNT 

If you are not using SDAC, and RMM is your TMS, you see the following message instead: 

EDG4058I VOLUME 100066 REJECTED BY INSTALLATION OPENRULE COMMAND REJECT ACTION
