Autochanger control port to the port at which we found it. Networker managed tape autocleaning on. At least one drive was defined with multiple paths. All such drives are defined with a hardware identification as well as a path value to avoid confusion by uniquely identifying the drive. The hardware identification for all drives which have one is always autochanger_name - Drive # where “autochanger_name“ is the name you gave to the autochanger that was just defined, and the # symbol is the drive numer. Barcode reading to on. Volume labels that match the barcodes. Slot intended to hold cleaning cartridge to 29. Please insure that a cleaning cartridge is in that slot Number of times we will use a new cleaning cartridge to 50. Cleaning interval for the tape drives to 6 months. You can review and change the characteristics of the autochanger and its associated devices using nwadmin. Would you like to configure another jukebox?
