Radoslaw, As Greg indicated, this WWID field is for use with a 3592/WORM cartridge. You may or may not need an upgrade to your 3592 devices; but the cartridges themselves are unique. As WORM indicates, they are Write-ONCE-Read-Many (the ONCE being the key). After you have written data to them you can MOD onto the last file or add additional files. But the tape can never go scratch and be re-used. Once you have data written, that data will remain until the tape is destroyed. And NEVER use a utility that writes its own EOV records; once EOV's have been written the tape is 100% full (even if its not) and nothing further can be put onto the cartridge. MVS will not allow a new secondary file to be placed behind the EOV records and MVS will not allow you to MOD onto a file that ends with EOV records.
