The following material:

LTAPEDEV specifies the device to which the logical logs are backed up when you use ontape for backups. LTAPEDEV also specifies the device to which data is loaded or unloaded when you use the -l option of onload or onunload. If you are using LTAPEDEV to specify a device for onunload or onload, the same information for TAPEDEV is relevant for LTAPEDEV.
