Page 13: Other Usage Models
A single-spindle disk, particularly a fast disk such as a 15K RPM drive, will be sufficient for LTO-2 tape drives, but be aware of other factors that can affect performance—such as, compressibility of data, disk fragmentation and the number of files. - Page 14 Further details about suitable products can be found on http://www.oracle.com/us/products/servers-storage/storage/ tape-storage/029151.htm. It is important to check for software compatibility and install any recommended upgrades. NOTE: Certain backup applications require you to use their own tape driver instead of the Solaris tape driver. Before you start...

Page 15: Installing An Internal Lto Scsi Tape Drive
Check the internal drive's SCSI ID Your LTO tape drive is shipped with a default SCSI ID of 3. Each device on the SCSI bus must have a unique SCSI ID. 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 not be used unless the tape drive is on a dedicated SCSI bus. -
Page 16: Prepare Mounting Bay
ID you want. Spare jumpers are provided with the drive. Prepare mounting bay You need one industry-standard, 5¼-inch, half-height bay in which to install the LTO tape drive. WARNING! To avoid personal injury or damage to the server or tape drive, ensure that the server is disconnected from the main power supply while you install the drive. -
Page 17: Attach Mounting Hardware
The LTO half-height drive only allows 3 mm of the engagement of the screw into the drive. If you remove an existing drive, do not assume the screws that you remove are the correct length for your new LTO drive. Always use 3 mm screws and use washers or shims to tighten, if necessary. -

Page 19: Install Drive
Check your server or HBA documentation to ensure that the SCSI bus and cabling supports the tape drive's bus speeds: Ultra320 for LTO–4 and LTO–3 tape drives, Ultra160 for LTO-2 tape drives. See also “Why is the SCSI bus type important?”... -
Page 20: Where Should The Scsi Terminator Be
If the drive is the last device on the SCSI chain, make sure that the SCSI cable is terminated correctly. Daisy-chaining two devices is not recommended. If you were to do so, do not mix drive families (daisy-chain only with other LTO tape drives) and do not daisy chain any Ultra320 devices. 1. SCSI cable 5. -

Page 23: Installing An External Lto Scsi Tape Drive
Check the external drive's SCSI ID Your LTO tape drive is shipped with a default SCSI ID of 3. Each device on the SCSI bus must have a unique SCSI ID. 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 not be used unless the tape drive is on a dedicated SCSI bus. -
Page 24: Connect The Scsi Cable
Do not connect the tape drive to a single-ended SCSI bus or to a RAID controller. For optimum performance, we recommend that your LTO tape drive is installed on a dedicated SCSI bus. If it is not, do not connect it to the same bus as your disk drive. -
Page 25: Does The Tape Drive Need A Terminator
The SCSI-OUT connector is only used when daisy-chaining two devices. This is not recommended. If you were to do so, do not mix drive families (only daisy-chain with other LTO tape drives) and do not daisy-chain Ultra320 tape drives. Does the tape drive need a terminator? If the tape drive is on a dedicated SCSI bus, it does not require a terminator. -

Page 35: Use The Correct Media
LTO tape drives use Ultrium tape cartridges. These are single-reel cartridges that match your drive's format and are optimized for high capacity, throughput and reliability. Compatible media can be recognized by the LTO logo, which is the same as the logo on the front of your drive. Do not use other format cartridges in your tape drive and do not use Ultrium cartridges in other format tape drives. -
Page 36: Worm Data Cartridges
WORM data cartridges are clearly identified by their distinctive, two-tone cartridge color. They can only be used with LTO tape drives that support the WORM feature. -
Page 37: Cleaning The Tape Drive
Clean LED will be on solid and the green Ready LED will flash. Each Ultrium Universal Cleaning Cartridge cleaning cartridge can be used up to 50 times with LTO tape drives. If the cleaning cartridge is ejected immediately with the Tape LED on, it has expired. -
Page 38: Operating And Storage Environment
• Do not drop cartridges or handle them roughly. • Stick labels onto the label area only. • Do not bulk erase (or degauss) LTO format cartridges because this will render them unusable. Operating and storage environment To prevent condensation and for long life, the cartridge should only be operated or stored as follows: •... -
Page 39: Troubleshooting
Check through the media chapter, “Use the correct media” on page 35. Check that you are using an Ultrium cartridge. Compatible media can be recognized by the LTO logo, which is the same as the logo on the front of your drive. -
Page 40: Optimizing Performance
A single-spindle disk may be sufficient for an LTO-2 tape drive, depending on your data's compressibility. Best practice to ensure good throughput is to utilize multiple disk spindles or data sources. -
Page 41: Problems With Cartridges
Use a new or known-good piece of media and see if it loads. If it does, the original cartridge is faulty and should be discarded. Check if another LTO drive of the same model will accept the cartridge. If it does, the original drive may be faulty. Before calling customer service, please check that the tape drive is responding. - Page 42 Troubleshooting...

Page 43: A Scsi Configuration Guide
They are designed to operate on a low voltage differential (LVDS) SCSI interface and are not compatible with high voltage differential (HVD) SCSI devices. LTO-4 and LTO-3 tape drives support a burst transfer rate of 320 MB/sec; LTO-2 tape drives support a burst transfer rate of 160 MB/sec. -
Page 44: Setting Up The Scsi Bus
Various terms are used when describing SCSI devices. These terms relate to factors that affect performance and cable length: • The speed of the data bus, which may be Fast, Ultra, Ultra2, Ultra3, Ultra160 or Ultra320. • The width of the data bus, which may be Wide or Narrow (16-Bit or 8-Bit). •... -

SCSI ID” on page 15. • On external LTO tape drives, the ID is displayed on the rear panel and can be set by pressing the little buttons above and below the number (using a ball point pen), see “Check the external drive's SCSI ID” on page 23. -
Page 46: External Drives
See the host bus adapter's documentation for details of how to do this. External drives For LTO external tape drives the enclosure provides active termination. As long as the drive is the only device on the SCSI chain, no terminators are required. The green ACT Term LED on the rear of the drive indicates whether auto-termination is active (on) or not (off). -
Page 47: Scsi Termination On A Single Lto Tape Drive
The green ACT Term LED on the rear of the first drive will be off while on the rear of the second drive it will be on. If the second device is not an LTO external drive, make sure that it is terminated using an LVDS-rated multimode terminator. -
Page 48: Scsi Cables
LTO tape drives have a 68-pin wide, high-density SCSI connector. A suitable cable with the correct termination is supplied with the tape drive. If you are using an LTO drive on an internal bus with other peripherals that run at Ultra2 speeds, it is important that a 68-pin LVDS-compatible ribbon cable is used. -
