When used in random-access mode, the VLS allows software selection of any cassette in the magazine in any order. You can logically divide cassette usage to satisfy particular data storage needs. For example, you can assign one or more cassettes to specific data functions (such as certain directories or network servers), or you can assign specific cassettes to individual users.

If you select "Y" for "Lpbk" the designated first cassette will be loaded into the tape drive after the last cassette has been filled and ejected. If you select "N" an error message will be issued and the backup will stop.

Warning We highly recommend that these diagnostic functions be used only by a qualified service technician (or on the instruction of a qualified technician). Some of these functions assume that the unit has been set up correctly and thus many of the normal built-in safety checks are turned off. Misusing these diagnostic functions without the normal safety checks could result in improper operation (or even damage to media or VLS). Equipment Description 25 Write EEPROM Mode The Write EEPROM Mode is used whenever you upgrade the VLS firmware. Refer to Appendix C in this manual for additional information. 26 Equipment Description Chapter 4 Operation and Maintenance This Chapter . . . describes normal operation features of the VLS provides details on the media and magazine explains normal maintenance procedures 27 The VLS unit is composed of one or two DAT drives and the robotics that control the drive(s), magazine and media. The drive status LEDs function per the manufacturer's specifications. No routine maintenance is required ­ apart from cleaning the heads after approximately each 8 to 10 hours of tape motion or when the Media Caution indication is displayed on the drive LEDs (see Cleaning the Drive Head later in this manual).

These data-grade cassettes are manufactured under more stringent environmental, reliability and durability specifications than audio-grade cassettes, producing superior data reliability. The 125-meter cassettes, used only in DDS-3 drives, and the 120-meter cassettes, which can be used in both DDS-3 and DDS-2 drives, are marked with the DDS-3 and DDS-2 logos, respectively. A write-protect switch is used to prevent recording over existing data. To prevent recording or deleting, place the write-protect switch to the open position. The drive senses the position of the switch and will not allow writing in this position. When inserting cassettes in the magazine, place the switch in the closed position (unless you do not wish to record on a specific cassette). 28 Operation and Maintenance Write-Protect Switch Open (Protected) Closed (Unprotected) Inserting Data Cassettes into the Magazine The magazine for the 4mm VLS holds fifteen 4mm cassettes. It includes a clear dust cover to protect the cassettes and for easy storage. Insert each cassette into a slot of the magazine making sure that the write-protect tab is on the top and the cassette faces toward you when the magazine is loaded onto the carriage of the VLS (as illustrated).

For example, for fastest access, data is usually stored on a local drive. If you have a very large file that is needed occasionally, you may store it on a tape in a VLS magazine, or on an optical drive. A host computer system that requests an operation to be performed by a target. [. . . ]
