o To examine the drive take-up leader, tilt the cartridge receiver door on the front of the drive and look inside to see that the drive leader is connected to the buckling link-hook, which should be engaged in the leader slot. DLT drive failure occurs Action: • Be sure the power and signal cables are properly connected. • Be sure the power and signal cable connectors are not damaged. • If the drive is connected to a nonembedded controller, be sure the controller is properly seated. DLT drive does not read tape Action: • Be sure the drive is seated. • Be sure the drive is installed properly. • Check each tape cartridge that has been used in the drive to see if a leader was dropped. After you locate any bad cartridges, dispose of them. A working tape drive will drop the leader of a bad cartridge, indicating that the cartridge needs replacing. • Refer to the tape drive documentation to be sure the type of tape being used is supported by the drive. Server cannot find the DLT drive Action: • Be sure a device conflict does not exist. Check for duplicate SCSI IDs in use and refer to the documentation of the DLT drive and the array controller to be sure they are compatible. • Be sure the maximum number of drives per controller has not been exceeded. Refer to the controller documentation to determine the capacity of the controller. NOTE: It is recommended that no more than two DLT drives per bus exist. • If using an external DLT drive that requires a SCSI terminator to be secured to the unused SCSI IN connector on the back of the drive, be sure the SCSI terminator is connected. DLT drives can be daisy chained, but do not connect more than three units per SCSI controller. The last DLT drive in the chain requires the SCSI terminator. • Check cables for damaged or bent connectors. An error occurs during backup, but the backup is completed Action: Contact the software vendor for more information about the message. If the error does not disrupt the backup, you may be able to ignore the error. Troubleshooting 37

Troubleshooting 37
o
To examine the drive take-up leader, tilt the cartridge receiver door on the front of the drive and
look inside to see that the drive leader is connected to the buckling link-hook, which should be
engaged in the leader slot.
DLT drive failure occurs
Action
:
•
Be sure the power and signal cables are properly connected.
•
Be sure the power and signal cable connectors are not damaged.
•
If the drive is connected to a nonembedded controller, be sure the controller is properly seated.
DLT drive does not read tape
Action
:
•
Be sure the drive is seated.
•
Be sure the drive is installed properly.
•
Check each tape cartridge that has been used in the drive to see if a leader was dropped. After you
locate any bad cartridges, dispose of them. A working tape drive will drop the leader of a bad
cartridge, indicating that the cartridge needs replacing.
•
Refer to the tape drive documentation to be sure the type of tape being used is supported by the
drive.
Server cannot find the DLT drive
Action
:
•
Be sure a device conflict does not exist. Check for duplicate SCSI IDs in use and refer to the
documentation of the DLT drive and the array controller to be sure they are compatible.
•
Be sure the maximum number of drives per controller has not been exceeded. Refer to the controller
documentation to determine the capacity of the controller.
NOTE:
It is recommended that no more than two DLT drives per bus exist.
•
If using an external DLT drive that requires a SCSI terminator to be secured to the unused SCSI IN
connector on the back of the drive, be sure the SCSI terminator is connected.
DLT drives can be daisy chained, but do not connect more than three units per SCSI controller. The
last DLT drive in the chain requires the SCSI terminator.
•
Check cables for damaged or bent connectors.
