DLT drive problems
Server cannot write to tape
Action:
• If the drive cleaning light is on, clean the drive.
NOTE: DLT cleaning cartridges are good for only 20 uses. If the cleaning cartridge is near that
limit and the drive cleaning light is still on after running the cleaning cartridge, use a new cleaning
tape to clean the drive.
• If the tape is write protected, remove the write protection. If the tape still does not work, insert another
tape into the drive to see if the original tape is faulty.
• Refer to the tape drive documentation to be sure the type of tape being used is supported by the drive.
• Check each tape cartridge that has been used in the drive to verify its condition and inspect its tape
leader to verify it is not damaged and is in the correct position. After you locate any bad cartridges,
dispose of them. A working tape drive may drop its leader when using bad cartridges, indicating that
they need replacing. If bad cartridges are found, you will need to inspect the DLT drives leader
assembly.
o To examine the cartridge 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.
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.
