| If | Then |
|---|---|
| The tape cartridge is not in the tape drive, and the Operate Handle light is blinking. |
Carefully close the tape drive handle until the Operate Handle light comes on and is steady. Reopen the tape drive handle. |
| The tape cartridge is in the tape drive and the Operate Handle light is on and steady (other lights may also be on). |
Slowly lift the tape drive handle to eject the cartridge. |
| The tape cartridge is in the drive and: ° The Operate Handle light is not on, or it is blinking ° The Tape in Use light is blinking steadily for more than four minutes ° All four top lights are blinking |
Ensure that the drive handle is completely closed. Gently press on the handle to close it. Attention: If the problem persists, suspect a defective tape cartridge, which causes the drive leader mechanism to detach as it is inserted into the tape drive loader. The detached leader requires a tape drive replacement. If a tape cartridge is found to be defective (see 'Tape Cartridge Inspection Procedure'), never reuse this tape cartridge in another tape drive. It will require tape drive replacement or each drive in which it is inserted. If closing the handle did not fix the problem, proceed to the next step. |
| The tape cartridge may or may not be in the drive, and all top and bottom lights are blinking (even after you have ensured that the drive handle is completely closed). |
Do one of the following to reset the tape drive: ° Press the Unload button on the tape drive bezel ° Turn the power to the library off, then on If the drive performs the Power-On Self Test (POST) without errors (no blinking status lights), remove the cartridge from the drive (if it was still in the drive). You may have to press the Unload button again. After the Operate Handle light comes on, lift the handle and carefully inspect the ejected cartridge. If there are no obvious defects, proceed to 'DLT7000 Tape Drive Diagnostic and Fix Verify Selections'. It POST failed (the status lights are blinking), turn off the power to the library and replace the tape drive (see 'Removing and Replacing a Tape Drive'). If a tape cartridge is still in a tape drive, remove it (see 'Manually Removing a Tape Cartridge'). After removing the failed tape drive and installing the replacement drive, perform the test in 'DLT7000 Tape Drive Diagnostic and Fix Verify Selections'. |
| The SERVICE REQD message displays on the operator panel. |
See the Then... path for the preceding four conditions. |
| Your system does not recognize the DLT7000 tape drive, or you are experiencing SCSI problems. |
Do one or more of the following: ° Configure your system to see the SCSI ID. ° Change your SCSI ID to a unique ID. Reconfigure your system, then turn the power off and on. ° Check your SCSI adapter installation to ensure that the parameters are correct. ° Check the pins on the SCSI cables, then reset the cables. Make sure that the cables are properly connected. ° Make sure that the termination is correct (see 'Terminators'). The terminator may be missing, there may be too many terminators, or the terminator may be incorrectly or loosely connected. Check for bent pins. ° Make sure that the SCSI cable length is correct and is not too long (see 'SCSI Cable Lengths'). |
| You received a system message or error sense data indicating a media or hardware problem or failure (sense key 03 or 04). Note: Tape drive load and unload problems could possibly be caused by library failure. Use the appropriate library diagnostics to further isolate the failure. |
For the additional sense code (ASC) and additional sense code qualifier (ASCQ) information from the sense data, see Figure 61. Verify or recreate the tape drive media or read/write problems using the DLT7000 diagnostic (DLT DIAGNOSTIC) from the tape library operator panel (see 'DLT DIAGNOSTIC - DLT7000 Read/Write Test'). Perform this test before removing or replacing the DLT7000 tape drive. ° If the DLT DIAGNOSTIC passes, suspect an intermittent tape drive problem or a media problem. Repeat the test as required. ° If the DLT DIAGNOSTIC fails, turn off the power to the library and replace the tape drive (see 'Removing and Replacing a Tape Drive'). On the replacement tape drive, perform the test in 'DLT7000 Tape Drive Diagnostic and Fix Verify Selections'). Call the next level of support if you are unable to determine or isolate the problem. |
| Other tape drive sense key ASC-ASCQ system console error information was received. |
See Appendix C, 'Accessing the System Error Log (for the RS/6000 Only)' to review various error log capabilities and exercisers available for problem isolation. Also see the Figure 61 for descriptions of the error. Refer to Appendix C, 'Accessing the System Error Log (for the RS/6000 Only)' for help in extracting sense key information. Use any host system diagnostic or exerciser capability to help isolate SCSI communication problems from possible software application problems. Perform the tape drive load and unload test (DRVLDULD) from the tape library operator panel. This test performs SCSI communications as well as library and tape drive operations at the device level. Call the next level of support if you are unable to determine or isolate the problem |
