To unload a tape cartridge from the DLT2500XT stacker’s magazine, follow these steps: 1.
Chapter 5: Operation Replacing the Magazine in the Stacker To replace the magazine in the stacker, follow these steps: 1. Press the Open button. 2. Make sure that the magazine door is moved all the way to the left. 3. Holding the magazine by its handle, slide it into the stacker doorway, as shown in Figure 5-6. Since the magazine is slotted, you can reinstall it only in the correct orientation. 4. Move the locking lever at the left to the closed position to secure the magazine. 5.
Cleaning This command moves the tape from slot 0 in the magazine to the drive. In this example, the argument sc3d6l0 tells the system that the drive is located on SCSI bus 3 and the SCSI device ID is 6. To unload a tape from the drive into slot 0 in the stacker’s magazine, enter a command similar to % /usr/sbin/stacker -u 0 /dev/scsi/sc3d6l0 This command unloads the tape from the target drive sc3d6l0 (SCSI bus 3 device ID 6) and puts it into slot 6 in the stacker’s magazine.
Chapter 5: Operation Every time you use the cleaning cartridge, the drive uses a new, unused portion of the tape. After approximately 20 cleanings, the entire tape is used and you must obtain a new cartridge. Therefore, it is a good idea to keep track of the number of times you use each cartridge. To clean a DLT2000XT tape drive, follow these steps: 1. Load the cleaning cartridge into the drive and close the handle.
Chapter 6 6. Troubleshooting and Maintenance This chapter tells you how to identify and troubleshoot simple problems with the DLT2000XT tape drive or DLT2500XT stacker after it has been installed.
Chapter 6: Troubleshooting and Maintenance • The sled-mounted DLT2000XT tape drive may be plugged into the wrong SCSI channel. • The power supply for the DLT2000XT tape drive or DLT2500XT stacker may be malfunctioning or dead. Caution: The power supply in the desktop DLT2000XT tape drive or DLT2500XT stacker should be repaired only by qualified service personnel.

Chapter 6: Troubleshooting and Maintenance If you cannot read or write tapes in the DLT2000XT tape drive even though it is listed in hinv, it is possible that the device driver was not properly created during system bootup.
Solving Basic Problems on the DLT2000XT Tape Drive or DLT25000XT Stacker Table 6-1 (continued) General DLT2000XT Tape Drive Problem Symptoms and Possible Symptom Possible Solutions The host is registering numerous SCSI errors. Are the SCSI cables firmly connected? Are there any bent SCSI pins? Is the proper desktop DLT2000XT tape drive SCSI terminator in place? Is the external SCSI cable within acceptable length limits? External SCSI device or cable diagnostic fails at power on.
Chapter 6: Troubleshooting and Maintenance Removing a Jammed Tape Cartridge The following instructions are intended to help you if a tape cartridge becomes jammed in the DLT2000XT and will not unload. In the case of a stacker that fails to unload a tape, note that a full magazine precludes the tape from unloading. Before calling your service provider, try the following: 1. If the tape fails to unload, power the unit off and then on again, and push the Unload button again. 2.
Updating Firmware From a Tape Cartridge Updating Firmware on Sled-Mounted and Desktop DLT2000XT Tape Drives Follow these steps: 1. Make sure tape operations are finished. For the firmware update to be successful, the drive must have passed the power-on self-test (POST). 2. Remove any cartridge in the DLT2000XT tape drive and close the load/unload handle. 3. Press down and hold the Unload button for about six seconds until the Write Protect LED blinks.
Chapter 6: Troubleshooting and Maintenance If the firmware is already at the same level as the code on the tape, the DLT2000XT tape drive does not go through the update process. If the firmware is not at the same level as the code on the tape, the drive code goes through a two- to three-minute update. During this time, the Write Protect and Tape in Use LEDs flash alternately.
Updating Firmware From a Tape Cartridge 4. Press and hold the Display Mode button for about five seconds until the SCSI ID SEL message displays. 5. Press and hold the Load/Unload button until the SCSI ID SEL message starts to flash. Immediately release the button, and then press it again. The CODE UPDATE MODE message now displays. 6. Press the Open button twice to open the magazine door. Load the magazine into the stacker and close the door. Wait until the elevator stops scanning the magazine. 7.
Chapter 6: Troubleshooting and Maintenance In the third case, follow these steps: 1. Press the Load/Unload button to unload the tape cartridge from the drive. 2. Press the Open button to open the magazine door. Remove the magazine and close the door. The stacker does an elevator scan. 3. Open the door again. The message LDR RDY displays. 4. Try the code update procedure again If the update is still unsuccessful, contact your service provider.
