Chapter 1 The Scalar Series This Chapter … p provides a brief overview of Scalar Library features. For detailed specifications, see Appendix C.
W 2 elcome to your new adic Scalar Library (Scalar 458 shown above). Your new library is a fully automated, high-performance, high-capacity, mass storage system. The Scalar Series is designed to provide you with unattended, near-line and off-line data storage, archiving, backup, hierarchical storage management (HSM), and retrieval for mid-range and high-end servers and networks.
The Scalar Series models (Scalar 224, 448, 458) are SCSI-2 compliant library systems incorporating streaming tape cartridge data storage devices which feature high capacity, high throughput, and data compression. Equipped with four Digital Linear Tape (DLT) drives, your library operates as five independent SCSI devices on up to five SCSI buses. Your library can contain up to 58 data cartridges providing a maximum formatted capacity of 4.
l Manual Cartridge Use. Individual cartridges can easily be transported to the drives through the Mailbox. l Cartridge Pre-Check. Whenever you power up your Scalar Library the Media Picker will scan the cartridge storage slots and build a log of valid cartridge locations. Sensors in the Mailbox allow a similar mapping of the area. l Reverse Cartridge Protection. The cartridge storage slots, and the slots in the Mailbox employ a design that prevents the cartridges from being inserted incorrectly.

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.
Using the Mailbox (Scalar 458 only) On-Line Mode When the Scalar Library is in On-Line Mode the application software is in control and directs all library operations. The application software can use the Mailbox to insert or remove individual cartridges to/from the drives, or to/from the cartridge storage shelves. Follow closely the instructions the application software provides on your host computer system monitor.
Off-Line Mode When the Scalar 458 Library is in Off-Line Mode you can use the Mailbox to insert or remove individual cartridges to/from the drives, or to/from the cartridge storage shelves. If your application software does not automate the drive head cleaning, use this procedure to manually perform the head cleaning As in On-Line Mode the access control doors are unlocked, except when the library is picking or placing a cartridge.
After you have completed the intended manual operation with this cartridge, follow the procedure outlined in the next subsection, Unloading a Cartridge from Drive, if you are going to unload the cartridge from the drive and remove it from the library. p Return the Scalar 458 Library to the On-Line Mode by pressing the MENU key on the Operator Panel. Your Scalar 458 Library is once again ready for use.
Note Remember, the access control doors are locked whenever the library is performing a pick or place operation. p Return the Scalar 458 Library to On-Line Mode by pressing the MENU key on the Operator Panel. Your Scalar 458 Library is once again ready for use. Moving a Cartridge to/from the Storage Shelves The same functions are performed as loading or unloading a cartridge from a drive to move a cartridge between the library storage shelves and the Mailbox.
Normal Maintenance Cleaning the Drive Head Cleaning Tape The tape heads should be cleaned once a month, or when the Use Cleaning Tape LED is illuminated on the drive front panel. Use a DLT cleaning tape to clean the drive heads. A cleaning tape is shipped with your adic Scalar Library. Figure 16:. DLT Cleaning Tape Cleaning the head should always be performed as the first step if the Use Cleaning Tape LED is illuminated on the drive.
The following table tells you when to use the cleaning tape: If . . . 1. It means . . . You should . . . The Use Cleaning Tape LED The drive head needs cleaning or the is illuminated on the drive front tape is bad panel Use the cleaning tape. Load the cleaning tape using the procedure in section Using the Mailbox, subsection Loading a Cartridge into Drive. When cleaning is complete, the beeper will sound alerting you to remove the cleaning tape.
Note To initiate the cleaning cycle manually you must be aware of the present state of the Scalar Library and the drive that you wish to clean. If a cartridge is present in the drive, you must first press the UNLOAD button on the drive front panel, then, when the OPERATE HANDLE LED is illuminated, open the drive door and remove the cartridge. You can then proceed with these instructions.
• Worn heads. The tape heads will eventually wear out causing the time between cleanings to get shorter and shorter. The DLT2000XT, DLT4000, and DLT7000 drives have a head life rating of 30,000 hours. Cleaning the Enclosure The outside of the enclosure can be cleaned with a damp towel. If you use a liquid all-purpose cleaner, apply it to the towel. Do not directly spray the enclosure.
