5 Installing the tape library 5.1 AP Series TL4000 4U tape library features and requirements The AP Series tape library provides a compact, high-capacity, low-cost solution for simple, unattended data backup. This unique design houses up to 48 tape cartridges in a compact 4U form factor with easy access to tape cartridges via two removable magazines and a mailslot. The magazines can hold up to twelve (left magazine including mailslot) and twelve (right magazine) cartridges.
5.2 SCSI requirements The AP Series tape library incorporates a wide SCSI-2 or SCSI-3 Low-Voltage Differential (LVD) SCSI bus, but may also be attached to a Single-Ended (SE) SCSI bus. Make sure your SCSI host adapter or controller supports these standards. If you connect the library to an SE SCSI bus, or if there are SE devices attached to the same SCSI bus, the library’s performance is limited to the maximum data transfer speed and maximum cable lengths of the SE bus.
Preparing the host IMPORTANT: Use proper procedures to prevent electrostatic discharge (ESD) (see use wristgrounding straps and anti-static mats when handing internal components. Follow these general guidelines: Make sure that your backup application supports the SCSI host bus adapter. If the host server is connected to a network, check with the system administrator before turning off power. Install a suitably rated HBA.

Figure 12 Securing the library to the rack Connecting the SCSI and power cable NOTE: The LTO3 tape drive is an Ultra 160 or 320 SCSI LVD device. Only cables and terminators specified for Ultra160 or 320 use or labeled as Multi Mode should be used. WARNING! Approved power cord for your specific geographic region.
Remove before operation! 3. Attach the other end of the SCSI cable to the connector on the SCSI host bus adapter or to the connector on the previous device on the SCSI bus. NOTE: The host bus adapter should be LVDS. A SE SCSI host bus adapter will work, but will severely degrade performance, and limit cable length. If there are any SE devices on the same SCSI bus, the entire SCSI bus will negotiate down to SE speed and severely degrade performance. Never attach the LTO3 tape drive to a SE SCSI bus. 4.
7. Turn on the library using the power button. Check the LCD screen to make sure the library is receiving power. If it is not, check the power connections and your power source. During the Power-On-Self-Test (POST), all four LEDs are illuminated briefly, followed by a flashing Ready LED. When the initialization sequence is complete, the Home screen will be displayed. 8. Plug in the host server or workstation and all attached devices. 9. Turn on any other devices you turned off earlier. 10.
6 Operating the tape library 6.1 Operating Modes There are 2 basic modes that the OCP operates in. First is the User Interaction mode. This mode is employed when a user is pushing buttons on the Op-Panel. The second mode is the System Driven mode. This is the normal mode of operation. In this mode, the Op-Panel displays status associated with the actions that were caused from commands issued via the Drive’s serial interface. Actions like Loading, Rewinding or Moving tape will be displayed.
Figure 15 Start-Up Screen After this initial status screen the home screen will be shown until a key is pressed. This home screen shows the overall health of the loader, indicating the status of the robotic and the connected drives.
6.4 Note about the LED’s All LEDs are updated during Power Up and Reset sequences. Upon power up or software Reset, the loader will illuminate all LEDs as soon as POST allows. This will help the User to verify if all LEDs are functional. When initialization starts, all LEDs will be extinguished and the Ready/Activity LED will flash at a reasonable rate of approximately 1-second per cycle, 50% duty cycle.
6.6 Power ON/OFF Part of the operator control panel is the Power On/Off button. Pressing this button will initiate a controlled Power Down of the unit (soft landing).

9 Troubleshooting 9.1 Installation problems Problems encountered during the installation of the library are usually caused by improper SCSI bus configuration, application software configuration errors, or an incorrectly configured operating system. If the application software that you are using is not communicating with the library after installation, check the following: SCSI ID: The library uses a single SCSI ID.
Device Driver Installation: Make sure that the proper device driver, if applicable, is installed for the library. Contact your support representative for more information. NOTE: Many backup applications use their own drivers for the library and drive. Before installing a driver, make sure it will not be in conflict with the software. 9.
Cannot write to or read from tape. Make sure that the cartridge is write enabled (move the write-protect switch to the enabled position). Make sure you have the appropriate data cartridge for your library model. Make sure you are using an Ultrium cartridge that has not been degaussed. Do not degauss Ultrium cartridges. Make sure that the cartridge has not been exposed to harsh environmental or electrical conditions and is not physically damaged in any way.
Bad performance Try a new cartridge. A marginal cartridge can cause performance problems due to bad spots on the tape requiring retries. Backing up data that compresses poorly or is already compressed will lower performance. Check the size of the files. Small file size can impact performance. Confirm that the backup application is utilizing block sizes of at least 32KB, preferably 64KB. Refer to the backup application documentation for details.
9.3 Device not properly terminated. See ”Installation problems” on page 60. Power on device before powering on the host computer. Check that the device has been powered on and is not in an error state. Check the SCSI connector for bent pins.
