Appendix D. Troubleshooting

The first step in problem solving is establishing whether the problem lies with the cartridge, the drive, the host computer and its connections, the backup software or with the way the system is being operated. If none of the following advice helps you solve the problem, contact your supplier.

The computer starts but does not recognize the tape drive

Possible reason	Recommended action

The power or SCSI cable is not connected properly.	Check that the cables to the tape drive are firmly
	connected. Ensure that the SCSI cable is LVD-compliant
	and that it does not have any bent pins. Replace if
	necessary.

The SCSI bus is not terminated correctly.	Check that the SCSI bus is actively terminated. (Refer to
	the documentation for your SCSI controller and any
	other SCSI devices you have).

The SCSI ID address of the tape drive is not unique.	Make sure that each device connected to the SCSI
	controller has a unique SCSI ID. Remember that 7 is
	normally reserved for the host bus adapter.

The application does not recognize the tape drive

Possible reason	Recommended action

The application does not support the tape drive.	Refer to your manufacturer’s World Wide Web site for
	details of backup applications that support the Ultrium
	tape drive. Load any service packs as necessary.

Some applications require drivers to be loaded.	Check that the correct SCSI and tape drive drivers are
	installed. Consult the installation notes of the backup
	application for details.

HH LTO specifications

IBM's Linear Tape-Open (LTO) technology has become a cornerstone of data storage solutions, providing organizations with a reliable, cost-effective means to manage the vast amounts of data generated in today’s digital age. The IBM HH LTO, specifically referring to the Half-Height Linear Tape Open drives, brings together advanced features and technologies tailored to meet the needs of modern enterprises.

One of the main features of the IBM HH LTO drives is their impressive storage capacity. The latest LTO generation can store up to 18 TB of uncompressed data per cartridge, and with data compression, that number can effectively double to 36 TB. This high capacity allows organizations to store large datasets efficiently without needing to invest heavily in multiple storage media.

In terms of performance, IBM HH LTO drives are engineered for speed. With transfer rates that can reach up to 400 MB/s uncompressed and 800 MB/s compressed, these drives ensure that data backups and retrievals are swift and efficient. This boosts operational productivity, allowing IT teams to focus on strategic initiatives rather than data management tasks.

Technologically, the IBM HH LTO utilizes advanced error correction and data integrity features. The integration of features such as Linear Tape File System (LTFS) simplifies data management by providing file-system-like access to tape data. This makes it easier for users to manage and retrieve specific files without the need to work through a cumbersome backup system.

Another characteristic that stands out is the drive's environmental sustainability. IBM LTO technology focuses on energy efficiency and lower total cost of ownership, making it an eco-friendly option for data archiving. The drives consume less power in standby modes, which aligns with enterprises’ growing sustainability goals.

Moreover, IBM's commitment to innovation is evident through its ongoing development of future LTO generations that are expected to enhance capacity, performance, and more advanced features, ensuring that businesses can continue to rely on LTO technology as their data storage needs evolve.

Overall, the IBM HH LTO drives embody a blend of high capacity, speed, reliability, and sustainability, making them an ideal choice for organizations looking to optimize their data storage strategy while preparing for future growth.
