6.4.1 Starting the Test

A Standalone Diagnostic test requires a tape that is not write-protected. The media type can be any media type that supports a tape format that can be written by the drive.

CAUTION: Since the test involves write operations, the existing tape contents will be destroyed!

1.Make sure that no cartridge is loaded.

No cartridge should be loaded at this stage. If a cartridge is loaded it can be ejected by clicking the Eject Button.

2.Enter Service Mode by keeping the Eject Button pressed for at least 6 seconds.

The Ready LED (on the left) starts flashing fast (indicating the drive is in Service Mode and that Service entry number 1 is active).

3.Insert the tape cartridge into the drive within 15 seconds.

The drive loads the cartridge and the Ready LED starts flashing indicating that Standalone Diagnostics has started. The eject button has now returned to normal mode. During the Standalone Diagnostics test, it is possible to abort the test and eject the cartridge by clicking the eject button. The drive indicates the detection of the abort request by flashing both the Ready and Activity LEDs. Depending on at which stage the test is aborted, it may take a while before the drive starts the eject operation. When the cartridge has been ejected, all LEDs are turned off (the Cleaning LED may however be on).

The Ready LED will continue flashing during the complete test. The Activity LED will be flashing when the test performs tape motion.

If no cartridge has been inserted after 15 seconds, the LEDs revert back to their initial state and the Eject Button must be pressed for 6 seconds again to get back to Service Mode.

6.4.2 Test Sequence

The Tandberg LTO HH Standalone Diagnostics test will perform the following operations:

Collect Information. Reads and stores drive and medium information:

•Firmware and Drive ID

•Tape type and format

•Cartridge serial number

•Error History Log and Log page 0x33 from EEPROM

•Run-time counters from EEPROM

Mainboard Test. Tests the mainboard hardware.

Cartridge Manipulation Test. The Cartridge Manipulation Test performs the same mechanical movement operations as those performed during Cartridge Load and Eject.

Read/Write Test. This test involves actual reading and writing on the tape medium. A write pass and a read pass are executed.

When the test has completed without errors the tape cartridge is ejected. No LEDs will be lit (the Cleaning LED may however be on).

6.4.3 Failure Indication

When a failure has been detected the tape is not ejected and the Failure LED will be flashing.

Detailed information can be retrieved by the ‘Receive Diagnostic Results’ SCSI command.

LTO-1 HH, LTO-2 HH, LTO-3 HH specifications

Tandberg Data has long been recognized as a leading provider of innovative data storage and backup solutions, and their tape drives, specifically the LTO-1, LTO-2, and LTO-3 Half Height (HH) models, represent a significant advancement in data storage technology. These systems are designed to meet the demands of modern data management, balancing capacity, speed, and reliability.

The LTO-1 HH, introduced in 2001, marked a groundbreaking step in the linear tape-open (LTO) technology. It offered a native storage capacity of 100 GB and a compressed capacity of up to 200 GB. The tape drive featured a data transfer rate of 20 MB/s, allowing for efficient backup processes. One of the key technologies in the LTO-1 was its use of ultral Linear Tapes, which helped in maintaining the integrity of data over extended periods. The built-in data compression capabilities also contributed to the efficient storage of large volumes of data, making it suitable for small to medium-sized businesses.

Building on the success of the LTO-1, the LTO-2 HH was launched, significantly enhancing performance with a native capacity of 200 GB and a compressed capacity of up to 400 GB. The data transfer rate improved as well, reaching 40 MB/s. The LTO-2 introduced the concept of WORM (Write Once, Read Many) technology, which added a layer of security by ensuring that data could not be tampered with after being written. This was particularly important for industries requiring regulatory compliance. Enhanced error correction and data integrity features were also hallmarks of the LTO-2, ensuring reliable long-term data storage.

The LTO-3 HH followed suit with even greater advancements, providing a native capacity of 400 GB and a compressed capacity of 800 GB, along with a data transfer rate of up to 80 MB/s. Its improved track layout and data encoding methods further enhanced performance and reliability. Additionally, LTO-3 introduced the partitioning feature, which divided the tape into virtual partitions for more efficient data management, allowing users to access data faster. The data encryption capabilities introduced with LTO-3 provided enhanced security, protecting sensitive data during backup and storage.

Together, these Tandberg Data LTO tape drives showcase a remarkable evolution in data storage technology, offering robust solutions that cater to businesses of all sizes. Their reliability, security features, and substantial data capacities ensure that organizations can efficiently manage their growing data storage needs in an increasingly digital world.
