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.

IF the two-color status LED is . . .	AND the other LEDs are . . .	THEN . . .
off,	off,	refer to the procedures for troubleshooting power
		problems under Computer Hardware Does Not Recognize
		the Tape Drive to determine why the green status LED is
		not on.
green,	on or flashing,	see Table 4-1 to determine whether the other LED activity
		is normal or abnormal. Then proceed to step 2 of this
		procedure.
		If the two-color status LED is flashing amber and the
		seven-segment LED displays the number "4" or "5" to
		indicate a Power On Self Test error, contact Technical
		Support to resolve the possible problem with the tape
		drive.
green,	off,	skip to step 3 of this procedure.

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.

IF . . .	THEN . . .
the two-color status LED is flashing green with no other indicators on,	wait for the tape to eject (normally takes from 2 to 3 minutes).
	• If the tape ejects, and the two-color status LED stops flashing green,
	the problem has been resolved.
	• If the tape does not eject, and there are no other LED indications,
	contact Technical Support to resolve the possible problem with the
	tape drive.

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:

•Watching the system the startup process

•Examining the system startup log files

IF the tape drive is . . . to a SAS controller,	THEN . . .
attached	proceed to step 2 of this procedure to determine whether the tape drive
	shares the SCSI bus with another active SCSI device.
not attached	attach the tape drive to a SCSI controller to achieve the best possible
	hardware performance for the best possible transfer rate.

2.If the tape drive is attached to a SAS controller, verify that the tape drive is detected by:
