While a media management application greatly simplifies and extends a tape library's capabilities, you can perform many tape functions in an iSeries™ environment with commands included in i5/OS™.
The following table shows the typical setup and operational tasks and associated CL commands for the tape library.
You need to use these commands if you do not use a media management application such as BRMS.
