2 Introduction This poster describes how to install your ActiTape LTO half-height internal tape drives with SCSI and SAS interface. Use the fixing screws supplied with the tape drive Connect to an Ultra320 SCSI HBA for LTO-4/LTO-3 Use the correct driver WARNING: To avoid personal injury or damage to the server or tape drive, disconnect your server from the mains power supply before installing the tape drive. To avoid damage to server or tape drive observe all recommended anti-static and power-grounding precautions, as specified in your server and tape drive manuals. Preparing the SCSI host IMPORTANT: Refer to for detailed compatibility information about operating systems and software applications. SCSI HBA We recommend an Ultra320 host bus adapter for LTO-4/LTO-3. If necessary, install a new HBA before you connect the tape drive. Ensure that you are connecting to a supported HBA running the recommended firmware version. Your tape drive will work with lower-rated LVDS SCSI but performance may be degraded. Single-ended SCSI will degrade performance and limit cable length. Do not attach to narrow or HVD SCSI. Drivers For Windows systems, download the latest drivers from For other operating systems, patch to the latest version of the operating system, following the instructions in the patch documentation.

3 Backup software Always upgrade your software application to ensure it works correctly with the tape drive. We do NOT recommend native backup applications, such as Windows Backup, because they do not support the full features of the tape drive and may cause performance problems. NOTE: Some backup applications require you to use their own drivers. Refer to the documentation of your software application to ensure you are using the recommended driver. Check the drive s SCSI ID Your actidata LTO HH tape drive is shipped with a default SCSI ID of 0. Each device on the SCSI bus must have an unique SCSI ID number. The drive can be assigned any unused ID between 0 and 15. Do not use SCSI ID 7, which is reserved for the SCSI controller. SCSI ID 0 is typically assigned to the boot disk and should also not be used unless the tape drive is on a dedicated SCSI bus. CAUTION: Static electricity can damage electronic components. Always wear an antistatic wriststrap if possible. If not, to equalize the electromagnetic charges, touch a bare metal part of theserver (such as the back plate) before you remove the tape drive from its bag.

4 SCSI ID jumper setting Set the SCSI ID by placing jumpers or by attaching a cable with a connector block in the middle of the connector J1 (see Item 3 in Error! Reference source not found.). SCSI IDs are set as shown in Figure 7 SCSI ID Jumper Settings by placing jumpers between the top and bottom rows of J1, when J1 is oriented as shown in the Figure With no jumpers the ID is set to zero; a jumper in place sets the ID bit to logic one. The rightmost column is the least significant bit. Note that the second to leftmost jumper is reserved. Connecting the SCSI tape drive CAUTION: Turn off and remove the power cords from the server and all attached accessories SCSI cable and termination Check your server or HBA documentation to ensure that the SCSI bus and cabling are the correct specification for your tape drive: an Ultra320 bus for actidata LTO-4 and LTO-3 drives. We recommend that you attach the SCSI ribbon cable directly to the SCSI host bus adapter. Daisy-chaining multiple devices is not recommended. If you do so, do not mix drive families (only daisy-chain with other LTO tape drives) and attach no more than two devices to the same SCSI bus. If the drive is the last device on the SCSI chain, make sure that the SCSI cable is terminated correctly. Power cable Attach a spare power cable from the server's internal power supply to the power connector (2). Page 4 of 11

5 Install and connect to a SAS host HBA Items Connector/Switch 1 Feature switch Block 2 SAS Connectors 3 Library Interface (LDI, or ADI) and Serial Port (for service use only) The following instructions are valid ONLY for servers with an HBA that supports internal SAS ports. You must purchase a supported HBA and cable, if you do not already have a SAS card installed. You need a spare PCI slot for the new HBA. 1. If necessary install the new HBA (Follow the instructions supplied with the HBA to install the new SAS HBA). 2. Install the tape drive 3. Connect the SAS cable supplied with the tape drive to the new HBA and the tape drive. 4. Connect the SAS and power cables to the tape drive. 5. Power up the server. Watch the boot screen carefully after installation. Check to see that the new SAS tape drive is listed in the boot sequence. If there are any error or unexpected messages go back and check the SAS cabling carefully. 7. Install drivers For Windows systems, download the latest drivers from For other operating systems, patch to the latest version of the operating system, following the instructions in the patch documentation. 8. Upgrade backup software Always upgrade your software application to ensure it works correctly with the Page 5 of 11

6 tape drive. We do NOT recommend native backup applications, such as Windows Backup, because they do not support the full features of the tape drive and may cause performance problems. NOTE: Some backup applications require you to use their own drivers. Refer to the documentation of your software application to ensure you are using the recommended driver. Power on the tape drive and verify connection Plug in the host server or workstation and all attached devices. Turn on any other devices you turned off earlier. Turn on the server. Check the Ready LED on the front panel to make sure the tape drive is ready for use. Verify the connection. Checking the performance of the product If performance is not meeting expectations and you are not meeting your backup window, check for bottlenecks in your system architecture. NOTE: See for recommended backup applications and for software configuration. What causes bottlenecks? 1. actidata recommends direct attach for LTO-4 and LTO-3 tape drives. If you back up over a network, anything less than Gigabit Ethernet may limit performance. 2. A single disk may limit backup performance. Have disks in parallel (e.g. RAID) if possible or, if your backup application supports interleaving of data, back up streams from multiple sources. 3. Use the latest version of your backup application. Native backup applications, such as Windows backup, may limit performance. Page 6 of 11

7 4. Connect the tape drive to a dedicated SCSI or SAS bus. Hardware encryption on your actidata LTO-4 tape drive Your actidata LTO-4 tape drive provides the ability to hardware encrypt your data, applying the strongest level of AES industry-standard encryption and protecting the data from unauthorized access and use. Encryption is supported only on actidata LTO TB media; media encrypted on a actidata LTO-4 drive can only be read on a compatible Ultrium tape drive that supports hardware encryption. Hardware encryption can be used with or without compression and without speed or capacity penalties. IMPORTANT: Hardware encryption is a powerful feature, but should be used with care. If you need to import your media onto another machine or to recover after disaster you will be required to enter an encryption key. Hardware encryption is turned off by default and is switched on by settings in your backup application, where you also generate and supply the encryption key. Your backup application must support hardware encryption for it to work. The software supplied with the tape drive provides this support. See for an up-to-date list of backup software. You should keep a record or backup of your encryption keys and store them in a secure place separate from the computer running the backup software. If you are unable to supply the key when requested to do so, neither you nor actidata will be able to access the encrypted data. Page 7 of 11

8 Selecting and looking after media Your high-performance tape drive works best with high-performance actidata LTO media. For optimum performance always use a data cartridge that matches the specification of your tape drive (see table). actidata LTO4-HH Actidata LTO-3HH LTO-2 format 400GB* Read only LTO-3 format 800GB* Read/Write Read/Write LTO-4 format 1600GB* Read/Write Read/Write NO * Capacity assumes 2:1 compression. The recommended cleaning cartridge is the actidata LTO universal cleaning cartridge. This cartridge is designed to work with any Ultrium drive and may be used for up to 50 cleans. Look after your media Many tape drive and backup failures are caused by damaged or badly handled tape media. Keep media in the case provided. Follow the temperature, humidity and acclimatization guidelines on the media packaging. Avoid dropping it or rough handling, as this is likely to damage the cartridge. Inspect it regularly for damage. Do not exceed normal cartridge life (260 full volume backup or restore operations).

9 Understanding the LED s and singlecharacter display on LTO4-HH Condition of Green Status LED Condition of Amber Status LED Condition of the SCD Panel Condition of the SCD Dot Meaning of LED and SCD Panel and SCD Dot Off Off Off Off The tape drive has no power or is powered off. Green/Solid Off Off Off The tape drive is powered on. Green/Flashing (at 1 Hz) Off Off Off The tape drive is reading from the tape, writing to the tape, rewinding the tape, locating data on the tape, loading the tape, or unloading the tape. The status light also flashes green if the tape drive contains a cartridge during the power-on cycle. In this case, the drive completes POST and slowly rewinds the tape (the process may take approximately 13 minutes). The light stops blinking when the drive completes the recovery and is ready for a read or write operation. To eject the cartridge, press the unload button. Off Amber/Solid Display Error Code On/Off Displaying error code on SCD at maintenance mode option 9. Off Amber/Solid Red/Solid On/Off The tape drive is in maintenance mode. Off Amber/Solid 1 Hz flashing, On/Off Exit from maintenance mode. Display of 0 Off Amber/Solid 1 Hz flashing, Display option On/Off Executing the selected option while in maintenance mode. Off Amber/Flashing at 1Hz Red/Solid Off If flashing at a 1-Hz rate, an error occurred and the tape drive or media may require service or it may require cleaning. Note the code on the singlecharacter display, and then go to Table 21 to determine the meaning of the error codes. If C then it requires that a cleaner cartridge be loaded. Off Amber/Flashing at 2 Hz Red/Solid Off If flashing at a 2 Hz rate, the drive is updating microcode. Off Amber/Flashing at 0.5 Hz Off Off If flashing at a 0.5 Hz rate, the drive detected an error and is performing a microcode recovery. It will reset automatically. Page 9 of 11
