W HOFRPH Congratulations on selecting the ADIC Scalar AIT 220 Library. Your new library provides unattended data storage, archiving, backup, and retrieval for mid-range and high-end workstations, servers, and networks. The robotic cartridge handling mechanism (CHM) automatically moves cartridges between tape drives and storage slots, while the tape drives read and write data. The library is available in standalone (vertical) and rack-mount (horizontal) models, as shown in the figure.
$ERXW WKH 6FDODU $,7 The Scalar AIT 220 includes two data cartridge magazines and either one or two 3.5” form factor Sony AIT tape drives. It can operate as three SCSI devices on up to three SCSI buses. When the library is is equipped with AIT-1 drives, the library is a differential SCSI-2 device and the drives are differential Fast/Wide SCSI-2 devices.
The Sony SDX1-25C, SDX1-35C, SDX2-36C, and SDX2-50C data cartridges support the Advanced Intelligent Tape format. The cartridges use a new recording format, Adaptive Lossless Data Compression (ALDC), Memory In Cassette (MIC) technology capabilities and use Sony’s AME media, which incorporates dual cobalt magnetic layers, the absence of binder material to prevent tape head contamination and a super-durable “diamond-like carbon” protective coating for extreme durability.
,QWHUQDO FRPSRQHQWV S Tape drives. The library can include one or two AIT-1 or AIT-2 tape drives, which are housed in drive carriers. S Data cartridge magazine(s) and fixed slot. The Scalar AIT 220 includes two removable 10-tape magazines on a rotor. The fixed slot allows you to store an AIT cleaning cartridge or an additional AIT data cartridge. S CHM (cartridge handling mechanism). The CHM is the robotic assembly that moves cartridges between the storage locations and the tape drives.
%DFN SDQHO FRPSRQHQWV S Fan and power entry module. The fan reduces the library's operating temperature. The power entry module includes the AC power connector, power switch, and fuse drawer.

,QVWDOODWLRQ DQG 6HWXS Step 3 – Prepare the host computer Make certain the SCSI host bus adapter card installed in the computer and the application software are compatible with the Scalar AIT 220. You can obtain software compatibility information about ADIC products from ADIC’s internet site (http://www.adic.com). Note: If your application only supports a single AIT tape drive, you can run the library in one of the sequential modes (see page 46 and page 153).
&KDSWHU Installing the library hardware This section provides step-by-step instructions for installing the library hardware. You can use the table below as a checklist. ✔ Step Description 1 Install the library into a rack, if you have a rack-mount model. 2 Unlock and open the front door. 3 Remove the packing foam. 4 Prepare and install cartridges. 5 Close and lock the door. 6 Connect the library to the SCSI bus. 7 Connect the power cord. 8 Power on the library.
,QVWDOODWLRQ DQG 6HWXS Step 1 – Install the library into a rack If you have a rack-mount library, follow these instructions to install the library into a standard EIA 19-inch rack. WARNING! Depending on the number of drives installed, the rack-mount library weighs 50 – 70 pounds (27.2 – 31.8 kg); the standalone library weighs 70 – 90 pounds (31.8 – 40.9 kg). At least 2 people are needed to move or lift the library. Most of the weight is toward the back of the library.
&KDSWHU To install the library into a rack: 1. Locate the slide rail assembly attached to each side of the library chassis, as shown in the figure. 2. Slide the rack-slide rail toward the rear of the library, as shown in the figure. Press the spring clips to remove the rack-slide rail from the chassis-slide rail.
,QVWDOODWLRQ DQG 6HWXS 3. Locate the mounting holes on the rack where you want to install the library. Allow 1½ inches (3.8 cm) minimum clearance below the bottom mounting hole. Note: If the rack does not have threaded holes, attach the clip nuts provided with the library over the mounting holes, as shown in the figure.
&KDSWHU 4. Orient the rack-slide rails so that the metal stop is towards the back of the cabinet, as shown in the figure. If the rails are not long enough to reach the back of the cabinet, use a T-15 TORX driver to loosen the nuts on the rails. Extend the rails to the desired length and tighten the nuts.
,QVWDOODWLRQ DQG 6HWXS 5. Using a T-25 TORX driver and four screws per rail, attach (but do not tighten) the rack slide rails to the mounting holes on the rack, as shown in the figure on page 7. 6. Adjust the distance between the rail brackets on each side of the cabinet to 17 5/8 inches (44.75 cm). Measure both the front and back. 7. Use a T-25 TORX screwdriver to tighten the screws to 12.0 inch-pounds (13.8 kg-cm) of torque.
&KDSWHU 8. Using two people to lift it, slide the library into the rack by inserting the chassis slide rails into the rack slide rails, as shown in the figure. Press the spring clips while pushing the library firmly into the rack. When the library is seated properly, you will hear the latch engage.
,QVWDOODWLRQ DQG 6HWXS Step 2 – Unlock and open the front door To open the front door, insert the key from your accessory kit into the lock, push in, and turn the key one-quarter turn to the right. Pull open the door.
&KDSWHU Step 3 – Remove the packing foam To remove the two foam packing pieces: 1. From inside the door, remove the first foam packing piece (rack-mount model shown below). 2. To remove the second foam packing piece, you must first move the cartridge handling mechanism (CHM) out and away from the magazine, as described on the next page. ➤ Important The CHM contains a bar code scanner. Do not touch the lens when you move the CHM. Smudges on the lens can cause scan errors. 3.
,QVWDOODWLRQ DQG 6HWXS Rack-mount model: ➊ Pull firmly on the upper portion of the CHM to slide it back (toward you). Do not pull on the CHM base. ➋ Push against the CHM base, sliding it firmly to the right or left. Standalone model: ➊ Pull firmly on the upper portion of the CHM to slide it back (toward you). Do not pull on the CHM base. ➋ Push against the CHM base, sliding it firmly to the top or bottom.
&KDSWHU Step 4 – Prepare and install cartridges Four types of AIT data cartridges are available: SDX1-25C, SDX1-35C, SDX2-36C and SDX2-50C. The SDX1-25C and SDX2-36C are 170 meters in length, while the SDX1-35C and SDX2-50C are 230 meters in length and all use Sony’s Advanced-Metal Evaporated (AME) tape.
,QVWDOODWLRQ DQG 6HWXS To prepare and install cartridges: Your library is equipped with a bar code scanner. You can affix bar code labels to the cartridges. To do this, position the label using the ridge on the cartridge for guidance. Make sure you orient the label correctly, as shown in the following illustration. ➤ Important If you remove a bar code label from a data cartridge without replacing it, make sure you clean the label area thoroughly.
&KDSWHU 4. Make sure the write-protect switches on the cartridges are set correctly, as shown in the following figure. You can use a ball-point pen or similar instrument to set the write-protect switch. If the orange tab fills the window, the cartridge is write-protected.
,QVWDOODWLRQ DQG 6HWXS 5. Remove the cartridge magazine (shown in the following figure). For rack-mount models, pull it out first from the right, then the left; for standalone models, pull it out first from the top, and then bottom. Access the back magazine by turning the rotor manually. CAUTION Make sure the CHM and its cabling are safely out of the way before you remove or install a cartridge magazine. If the CHM is blocking the magazine, move it by following the instructions on page 13.
&KDSWHU 6. Place the magazine on its feet with the single mounting guide toward the right. Position each cartridge so that the bar code label is on top and the write-protect switch is toward the front. Insert the cartridge into the magazine slot. Note: Very little force is needed to install a data cartridge. If it does not snap into place easily or if it protrudes further than the magazine’s center rib, check the orientation of the cartridge. 7. To re-install the magazine, follow the instructions below.
,QVWDOODWLRQ DQG 6HWXS 8. The library contains one fixed cartridge slot for a cleaning cartridge or an additional data cartridge. If desired, install a cleaning cartridge in the fixed cartridge slot, as shown on the following page. ➤ Important Use only a Sony SDX-TCL cleaning cartridge.
&KDSWHU Rack-mount model: Position the cleaning cartridge so that the window showing the tape reels is to the right and snap the cartridge into place. Standalone model: Position the cleaning cartridge so that the window showing the tape reels is to the top and snap the cartridge into place.
,QVWDOODWLRQ DQG 6HWXS Step 5 – Close and lock the door Close the door and turn the key a quarter-turn to the left. Step 6 – Connect the library to the SCSI bus This section provides general guidelines for connecting the library to the SCSI bus. The library consists of three SCSI devices: the library itself and the two tape drives. If a drive blank is installed, the library consists of two SCSI devices (the drive blank is not addressable). Before you begin 1.
&KDSWHU 5. For each device that terminates the bus (either the library or one of the tape drives), install a terminator on one of the connectors for that device. Connecting the Scalar AIT 220 The Scalar AIT 220 can operate on one, two, or three SCSI buses. The library, Drive 1, and Drive 2 can operate on separate SCSI buses or on the same SCSI bus. 1. Connect the library to the SCSI bus, using the connector assignments shown in the following figure.
,QVWDOODWLRQ DQG 6HWXS 2. If you are connecting the library and two tape drives to one or two SCSI buses, install a jumper (or jumpers) over the connectors between devices, as shown in the example.
&KDSWHU 3. For each device that terminates the bus (either the library or one of the tape drives), install a terminator on one of the connectors for that device. The example below shows a Scalar AIT 220 connected to three SCSI buses. All the buses are terminated.
,QVWDOODWLRQ DQG 6HWXS Step 7 – Connect the power cord ➤ Important The power cord shipped with the library is a 120 VAC three-conductor power cord for use in the United States and Canada. If you are planning to use an input voltage other than 120 volts AC or if you plan to use the library outside of the United States or Canada, you must supply your own power cord. Refer to page 135 for more information. 1. Make sure that the power switch on the back of the library is off (the 0 is pressed).
&KDSWHU 2. Connect the female end of the power cord to the power connector on the back of the library. 3. Plug the male end of the power cord into the power source. Note: The library has autoranging voltage selection, so you do not need to change the voltage setting. Step 8 – Power on the library 1. Make certain the library's door is closed and locked. 2. Turn on the host computer system.
,QVWDOODWLRQ DQG 6HWXS If problems occur . . . If the library does not power on as described: Check the following: S Is the power switch on (1 is pressed)? S Is the power cord inserted correctly? S Is the library door closed and locked? S Is the SCSI bus terminated? S Is the SCSI cable connected to the library and host computer? S Is the host computer system turned on? For additional troubleshooting tips, see “Problems with library installation” on page 128.
&KDSWHU Configuring the library Configuration steps include: S S S S Displaying the Configuration Menu Setting SCSI IDs Setting LCD security (optional) Setting other configuration options (if necessary) To change options, you will use the operator panel (LCD and keypad) on the front of the library, as shown in the figure. If desired, you can tilt the LCD for easier viewing.
,QVWDOODWLRQ DQG 6HWXS Step 1 – Display the Configuration Menu To display the Configuration Menu: 1. Access the Main Menu by pressing >(VFDSH@ on the keypad. The Main Menu is shown. →M a i n S c r e e n I n t e r C o n f f a c e M e n u i g u r a t i o n M a i n t e n a n c e M e n u M e n u ↓ 2. Press > @ to scroll down to Configuration Menu. Then press >(QWHU@.
&KDSWHU During library configuration, use the operator keys for the following functions: To select an item from a menu: Press > @ or > @ to scroll up and down through the items. When the screen arrow (→) points to the desired item, press >(QWHU@. To move the screen arrow left and right, or toggle some options: Press > @ or > @. To return to a previous screen Press >(VFDSH@.
,QVWDOODWLRQ DQG 6HWXS To view or change the SCSI IDs: 1. From the Configuration Menu, select Set SCSI IDs. The following screen appears: S C S I D 2 D 1 I D s : 3 2 L I B 1 ¦ ↓ → 2. To set the SCSI ID for Drive 2 (farthest from the magazine), press > @ or > @ until the screen displays the correct SCSI ID. 3. Press > @ to move the screen arrows to Drive 1. 4. To set the SCSI ID for Drive 1 (closest to the magazine), press > @ or > @ until the screen displays the correct SCSI ID. 5.
&KDSWHU Step 3 – Set security The Security option allows you to prevent unauthorized personnel from disrupting the operation of the library.
,QVWDOODWLRQ DQG 6HWXS Whichever method is used to enable security (operator panel or SCSI) must also be used to disable security. That is, if you enable security from the operator panel, you must disable it from the operator panel. If security is enabled by the application (SCSI), it must be disabled by the application. Note: To determine if security has been set by your application, look at the SCSI Mode Parameters screen (see page 93). Security remains in effect across resets.
&KDSWHU Disabling security from the operator panel 1. From the Configuration Menu, select Set Security Off. The following screen appears: S e t S e c u r E n t e r i t y P a s s w o r d f : 0 0 0 ↑ T h e n P r e s s O f E n t e r → Note: If the menu displays Set Security On, the LCD security function is disabled. However, security may have been enabled by your application using a SCSI command. If so, it must be disabled by your application. Refer to your software documentation. 2.
,QVWDOODWLRQ DQG 6HWXS Step 4 – Set other configuration options The Configuration Menu contains some other configuration options for the library, as described in the table below. If desired, you can check these settings and change them. Configuration options SCSI Parity* Allows you to enable parity checking for the library (if the SCSI adapter card connected to the library supports it). When enabled, the library checks all data on the SCSI bus for parity. This remains in effect across power cycles.
&KDSWHU * Parity checking for the library can also be enabled by the application software using the SCSI command, MODE SELECT. The method used last to set parity checking (LCD or SCSI command) has precedence. Parity checking for tape drives is set separately. Checking the setup After installing the hardware and software, check the setup by performing some exercises on the library, as described below.
,QVWDOODWLRQ DQG 6HWXS If problems occur . . . If the library and tape drive are not operating as expected: See Chapter 7 for troubleshooting information. If there is an error code displayed on the LCD: See Appendix J for a list of error codes and corrective actions. If you cannot solve the problem yourself: Contact your service provider or ADIC. Where to go from here Before you begin library operations, check the following: • A cartridge magazine is installed.
&KDSWHU 1RWHV 6FDODU $,7
/LEUDU\ 2SHUDWLRQ Once the library and application software are installed and configured, you can automatically perform backup and restore operations using the application software. You do not need to intervene in the cartridge processing during normal library operations.
&KDSWHU 8VLQJ WKH RSHUDWRU SDQHO The library includes a four-line LCD and keypad, called the operator panel, which allows you to interactively control library operations. Using the operator panel, you can set library options, check operating statistics, and diagnose errors. If desired, you can tilt the LCD for easier viewing. 0DLQ 6FUHHQ The Main Screen appears when you apply power to the library.

/LEUDU\ 2SHUDWLRQ 2SHUDWLQJ LQ GLIIHUHQW FRQWURO PRGHV To determine which interface will control CHM motion, you can set the library to one of the following control modes: S S S S S S SCSI Interface Sequential 1 Sequential 2 Dual Sequential LCD Interface 25/9-Pin These control modes allow you to operate the library with the application software (SCSI Interface), operate the library as a sequential stacker device (Sequential 1, Sequential 2, Dual Sequential), or perform diagnostic functions on the library
&KDSWHU &RQWURO PRGH GHVFULSWLRQV 6&6, ,QWHUIDFH PRGH If you want the application software to control library operations, you must set the library to SCSI Interface mode. In this standard operating mode, the application software controls the motion of the CHM by issuing SCSI commands across the SCSI bus. 1RWH The application software can issue commands to the library regardless of the control mode. However, the library must be in SCSI Interface mode for the application software to control CHM motion.
/LEUDU\ 2SHUDWLRQ /&' ,QWHUIDFH PRGH If you want to perform any operations from the operator panel that involve moving the CHM, you need to set the library to LCD Interface mode. All of these operations, such as cleaning the tape drives and performing diagnostics, are included under the Maintenance Menu. 1RWH LCD Interface mode is required only when you want to control the motions of the CHM. For example, you do not need to switch control modes to access the menus.
&KDSWHU From the Interface Menu, select Control Mode Menu. The following screen appears: → L C D I n t e r * S C S I f a c e I n t e r f a c e S e q u e n t i a l 1 S e q u e n t i a l 2 ↓ 1RWH The Sequential 2 option does not appear in this menu if you have a drive blank installed.

/LEUDU\ 2SHUDWLRQ 6WRULQJ FDUWULGJHV To maximize the shelf life of your tapes and ensure data integrity, follow these guidelines when storing cartridges: S Store cartridges in a suitable environment. Follow the specifications for storage temperature and other environmental requirements, as described on the cartridge packaging. Do not allow the temperature and humidity in the storage environment to fluctuate. S Keep the storage location as free of airborne particulates as possible.
&KDSWHU 5HVHWWLQJ WKH OLEUDU\ If the library has encountered an error and is still not operating after you have tried the corrective action for the error, you may need to reset the library. A reset causes the library and the tape drives to perform their power-on self tests. Unless configured otherwise, tape drives will rewind the tape after a reset, but will not eject the data cartridge.
7DSH 'ULYH 2SHUDWLRQ The application software automatically controls the tape drives to perform backup and restore operations.
&KDSWHU 0RQLWRULQJ WKH WDSH GULYH /('V The SDX-300C and SDX-500C tape drive use their three front panel LEDs to report the current status/operation of the drive. The following table shows the possible states of the three LEDs and the conditions they indicate.
7DSH 'ULYH 2SHUDWLRQ &OHDQLQJ WKH WDSH GULYHV You should clean a tape drive whenever the library displays “Drive needs cleaning” on the Main Screen of the LCD or whenever your application software notifies you. (Not all software applications display cleaning requirements.) Regular cleaning helps ensure that the tape drives function reliably. 1RWH Some applications monitor the tape drives’ cleaning needs and automatically insert the cleaning cartridge in the drive whenever it needs cleaning.
&KDSWHU Make certain a cleaning cartridge is installed in the fixed cartridge slot. (If the fixed slot contains a data cartridge and you follow these steps, you will have to manually eject the data cartridge from the tape drive.) If security has been enabled, disable it (see page 34). Switch to LCD Interface mode (see page 46). From the Main Menu, select Maintenance Menu. Then select Clean Drives Menu.
7DSH 'ULYH 2SHUDWLRQ Confirm that the cleaning was done by looking at the Status LED on the front of the drive. The Status LED should be off.

&KDSWHU (OHPHQW LQGH[HV Each element has an element index, which enables the library to identify the elements. Many LCD functions require you to use element indexes. For example, to move a cartridge using the Diagnostics Menu, you must specify the source and destination element indexes. The source is either a cartridge slot or the tape drive where the CHM will pick a cartridge. The destination is either the slot or the tape drive where the CHM will place the cartridge.
$GYDQFHG 2SHUDWLRQ ,QGH[HV IRU WKH VWDQGDORQH PRGHO (OHPHQW DGGUHVVHV Your application software may use element addresses to identify elements in the library. The difference between an element index and an element address is that an index is a fixed number set by the library, whereas an address can be changed by your application software (using the SCSI command, MODE SELECT). The element indexes correspond to the library's default element addresses.

On a single-ended SCSI bus, one signal line is used to transmit a bus signal between devices. On a differential bus, two signal lines are used. Your library is differential; all devices must be differential.
6&6, &RQILJXUDWLRQ Differential SCSI cable lengths. Make sure the total length of all internal and external cables on the SCSI bus does not exceed 82 feet (25.0 meters). If LVD devices are connected to the bus the total length of all internal and external cables on the SCSI bus does not exceed 41 feet (12.0 meters). Internal cabling. You must include the amount of internal cabling in your calculations. See “Determining the cable length for each bus” on page 136 for information.
$SSHQGL[ % If you have one tape drive installed, the library uses two SCSI IDs, one for the library itself and one for the tape drive. If you have two drives installed, the library uses three IDs. Separate IDs allow the library and tape drives to operate as independent devices, receiving different sets of SCSI commands from the host.

' . 6HTXHQWLDO 2SHUDWLRQ This appendix describes how you can operate the library in the sequential control mode: Sequential 1. +RZ VHTXHQWLDO RSHUDWLRQ ZRUNV When the library is operating in one of the sequential modes, its internal firmware instructs the CHM to move cartridges sequentially between the cartridge slots and one or both tape drives. No application software is required to support cartridge pick and place functions.
$SSHQGL[ ' In Sequential 1 mode, the library processes the cartridges in tape drive 1 (closest to the magazine). In Sequential 1 mode, the library performs the following steps: Picks the cartridge from slot 1 and places it in the tape drive specified by the mode (1 or 2). If the slot is empty, the CHM picks the next cartridge in the magazine. Waits until the tape drive ejects the cartridge, then returns the cartridge to its original slot.
6HTXHQWLDO 2SHUDWLRQ Depending on how the Loop option is set, either returns to the first cartridge and begins the process again, or stops. The Loop option is described on page 156. 1RWH In the sequential mode, the tape drive specified by the mode must be installed; the library will not switch to the other tape drive. If both drives are installed, the library ignores the additional drive. 6HTXHQWLDO RSWLRQV For Sequential 1 mode, you can set the Restart and Loop options.
$SSHQGL[ ' %HIRUH WKH OLEUDU\ UHVWDUWV Before restarting, the library performs the following actions: If the CHM was moving a cartridge, it finishes the move. (This includes inserting the cartridge into the tape drive if the CHM was moving a cartridge to a tape drive.) 1RWH If you attempted to open the door, the library does not release the door interlock until it has completed the move. The library performs a power-on self-test (POST).
6HTXHQWLDO 2SHUDWLRQ 5HVHWWLQJ VHTXHQWLDO SURFHVVLQJ If you want to resume sequential processing from the first cartridge, select “Set Next Cart to 1” from the Sequential Options menu.
$SSHQGL[ ' $YRLGLQJ LQWHUUXSWLRQV Although the library has effective methods for resuming operation, it is best to avoid interruptions when the library is operating sequentially. In particular: S Do not reset or power cycle the library unless absolutely necessary. Reset the library only to clear certain error conditions and power off the library only to perform maintenance or to store it. Avoid resetting or power cycling the library when a cartridge is in a tape drive or the CHM.
