5. Attempt to insert a different tape cartridge.
6. If a tape still cannot be inserted into the tape drive, contact Technical Support to resolve the possible problem with the tape drive.
Drive Does Not Eject the Tape Cartridge
If you cannot eject a tape cartridge from the PowerVault LTO-4-120 Half-Height tape drive:
1. Verify that the two-color status indicator is green and the other indicators are off/blank.
2. If other LEDs are on, reset the tape drive by either pressing and holding the Eject button on the front panel for more than 5 seconds and releasing it.
3. With the the two-color status LED green and the other indicators off, press the eject button on the front panel.
Slow Backup Operations
Many factors can make backups appear to be slow. To achieve the highest possible transfer rate, the PowerVault LTO-4-120 Half-Height tape drive must be
attached to a SAS HBA capable of a minimum of 3 GB/sec. Verify that the tape drive is attached to a Dell SAS HBA. You can do this by:
l Watching the system the startup process
l Examining the system startup log files
2. If the tape drive is attached to a SAS controller, verify that the tape drive is detected by:
¡ Checking:
n Windows Device Manager
n Linux logs

you see a message similar to:
You cannot eject the cartridge because the tape drive is in use. Wait until the
operation is complete before ejecting the cartridge. The backup software may
still have the tape drive in prevent mode so that the cartridge cannot be
ejected. Use the backup software commands to eject the tape.
use the mt offline command to eject the tape.
NOTE: In Linux environments, the message may not appear, even though
the operating system prevents the drive from ejecting the tape. Use the mt
offline command anyway.
