Media optimization
Media optimization is a new feature for the LTO-9 tape drive with L9 media. The increased number of tracks used to write data
on tape requires greater precision. Media optimization creates a referenced calibration for each cartridge that enables the tape
drive’s intelligent alignment to optimize data placement. LTO-9 media optimization enhances LTO tape long-term media
durability.
It is important to consider when media optimization will be performed:
Media optimization will be performed on first load of L9 media during initialization.
Recommendation is to perform first load in the location of deployment, which should be in a stable environment that
meets the recommended environmental specification.
Media optimization is a one-time operation that can be completed on any drive in the environment, enabling the media
to be used across all tape drives without further optimization.
Other considerations for media optimization:
Media optimization averages 40 minutes per first load of a cartridge to a tape drive. Although most media optimizations
will complete within 60 minutes some media optimizations may take up to 2 hours.
Interruption of the process is not recommended.
A different mount will not necessarily improve the time to complete the one-time optimization.
An update to software may be required. Contact your software application provider for more details. Customized software, not
provided as a standard market product, may require modification to ensure that the software can handle the extended first
mount time. For additional details, review the detailed section of the IBM LTO Ultrium Tape Drive SCSI Reference.
Operation Features
The half high LTO tape drive has the following operator controls.
Unload Button
Unload Button
The unload button (1 in Figure 1) is used to eject an installed tape cartridge, perform maintenance functions, and reset the
drive. The unload button operates only when the power is on. For more information on the Unload Button functions, see Unload
Button.
Indicator LEDs
The half high LTO has the following indicator LEDs.
