Restrictions for saving to multiple devices

The devices that you specify in a media definition must be compatible stand-alone tape devices or tape media library devices. The tape volumes that you specify must have compatible media formats.

Note: Your results may depend on the device type that you use. This is because different device types may identify different formats for the same media. For example, one 8mm device may identify a tape as having an FMT7GB format, while a different 8mm device might identify the same tape as having an FMT5GB format.

You may 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	DLTMEDDFN
Retrieve Media Definition	QsrRetrieveMediaDefinition QSRRTVMD
¹ For more information regarding these APIs, refer to System API reference. ² For more information regarding these CL commands, refer to System CL Command reference.

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 server has been enabled for CD-ROM premastering by using the Handle CD-ROM Premastering State (QlpHandleCDState) 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.
