Restrictions for saving to multiple devices

The devices that you specify in a media definition must be compatible standalone tape devices or tape media library devices.

The tape volumes that you specify must have compatible media formats.

Note: Your results might depend on the device type that you use. This is because different device types might identify different formats for the same media. For example, one 8 mm device might identify a tape as having an FMT7GB format, while a different 8 mm device might identify the same tape as having an FMT5GB format.
You might use a media definition on the following commands and APIs:
Name API1 Command2
Save Library   SAVLIB
Save Object QSRSAVO SAVOBJ
Save QsrSave SAV
Save Changed Object   SAVCHGOBJ
Restore Library   RSTLIB
Restore Object (Library)   RSTOBJ
Restore Object Integrated File System QsrRestore RST
Create Media Definition
QsrCreateMediaDefinition
QSRCRTMD
  
Delete Media Definition
QsrDeleteMediaDefinition
QSRDLTMD

Retrieve Media Definition
QsrRetrieveMediaDefinition
QSRRTVMD

For more information regarding these CL commands, refer to the CL command finder.
You must have *USE authority to the media definition, *EXECUTE authority to the media definition library, and normal save or restore authority for each device you specify in the media definition.
You cannot use a media definition if the save or restore command or API specifies any of the following:
  • Volume identifiers
  • A sequence number
  • A save file
  • An optical file

You cannot use a media definition if your system has been enabled for CD-ROM premastering by using the Generate CD-ROM Premastering Information (QLPCDINF, QlpGenCdPremasteringInfo) API.

Parallel format and media definition usage restrictions

  • SAVLIB LIB(*ALLUSR, *IBM, *NONSYS) cannot save data in parallel format. You will receive this error message if you specify a media definition in parallel format.
  • A media definition cannot be used to restore a list of libraries or generic libraries.
