Description
Incorrect cartridge
When an incorrect tape cartridge is used for the test, the cartridge is unloaded, the yellow
Fault LED remains on, and a P, 7, or J is displayed in the SCD. This can happen if the
cartridge is:
v Write-protected (P is displayed in the SCD.)
v Damaged (7 is displayed in the SCD.)
v Not write-compatible with the drive (J is displayed in the SCD.)
Press the eject button to end the self-test and return the drive to normal operating mode.
Then return to step 1 and run the self-test again using a suitable cartridge.
Returning to normal operation
When self-testing has completed successfully, the tape cartridge is unloaded. The drive is no longer in
diagnostic mode and returns to normal operation.
When self-testing fails, the tape cartridge remains loaded inside the drive, and the drive remains in
diagnostic mode. Press the eject button to unload tape cartridge and return drive to normal operation.
200/400 GB Half High Ultrium 2 tape drive (FC 5755)
Learn about the features of this media device.
The LTO half-high tape drive is a SCSI device that can be used for backing up, restoring and archiving
data. These files can include multimedia, imaging, transaction processing, large databases, and other
storage-intensive applications. Each tape cartridge can store up to 200 GB of data (uncompressed), or up
to 400 GB of data (compressed), assuming a 2 to 1 compression ratio.
Note: The actual capacity varies depending on the application, the type of data, and the tape cartridge.
200 GB is typical and 400 GB is possible when the Data Compression setting is activated. The default
setting of Data Compression is controlled by the host system. The user and the application software can
control the activation or deactivation of the data compression setting. The drive can optimally achieve a
2:1 compression ratio.
The LTO half-high tape drive FRU part number is 23R3248
The custom card identification number (CCIN): 63A0
The LTO half-high tape drive features:
v A sustained native data transfer rate of up to 24 MB per second, 48 MB per second at 2:1 compression
v Downward read and write compatibility with earlier LTO-type data cartridges.
v Uses the self-configuring SCSI device driver native to the host operating system.
v Can be used as an bootable device, depending on the host system configuration.
v 5.25-inch half-high form factor
v Streaming operation
Attributes required: One 1.6-inch (41 mm) half-high media bay and one SCSI-2 internal 16-bit address
