Send Volume Tag - B6h

Note: Send Volume Tag B6h is only supported by Scalar i2000 and i6000 libraries.

The library searches its existing inventory for barcode labels that match the volume tag template passed in with this command. The results of this search can then be retrieved through sending a subsequent REQUEST VOLUME ELEMENT ADDRESS command.

This command can be used to search for specific cartridges or ranges of cartridges within the library. A REQUEST VOLUME ELEMENT ADDRESS command must be sent to retrieve the results of the search. The results only reflect those of the most recent SEND VOLUME TAG command.

The SEND VOLUME TAG CDB format is shown in the following table.
