librarymediaoptimization

Starting with LTO-9 the LTO tape drive will perform a media characterization/optimization process for each initially loaded cartridge.

Regarding the longer lasting optimization time, cartridges should be optimized proactively in the target environment.

The%librarymediaoptimization; subcommand for medium changers offers the option to identify uninitialized cartridges in a logical tape library and load cartridges in the desired tape drive(s) for optimization.

This subcommand with no parameters determines all tape drives and storage slots available in a logical tape library and use those for media optimization.

Already initialized cartridges will be skipped.

With the optional -start number parameter, the first storage element address can be specified used for and with optional parameter -slots numberofslots, the numbers of slots can be limited.

The optional parameter-drives numberofdrives specifies the numbers of drives and with the optional parameter -drivelist identifiers, a defined list of drives is used -identifiers is a comma separated list containing the drive element address or the drive serial number.

The optional parameter -volserlist identifiers allows the specification of a list of volser names where the media characterization/optimization should be performed, identifiers is a comma separated list containing the volser names. The characters * and ? can be used as wildcard characters .
