CHAPTER 5 Using Your Tape Drive This chapter describes how to start using your tape drive system. This includes making a trial back-up, cleaning the tape mechanism, and various troubleshooting information. This chapter also includes information on the LEDs and buttons on the front panel of the system. This chapter covers the following topics: • “Power On Self Test” describes the sequence of activities that occur when power is first applied to the drive.
CHAPTER 5: Using Your Tape Drive SDLT 220 and SDLT 320 Product Manual 5.1 Power On Self Test When power is applied to the tape system, the system performs a Power On Self Test (POST). POST completes in approximately ten seconds. While POST is running, the tape system responds BUSY to SCSI commands. The tape system also responds to various SCSI messages during POST. During this time, if a host tries to negotiate Synchronous or Wide transfers, the tape system will negotiate to Asynchronous or Narrow.
SDLT 220 and SDLT 320 Product Manual CHAPTER 5: Using Your Tape Drive 5.2 Performing a Trial Back-up Complete the following steps to perform a trial back-up and verify the tape drive has been correctly installed: • Insert a cartridge. Push the cartridge completely into the system. The tape will load automatically. • Choose a sample file set from the host computer. • Perform a back-up and then restore the file set.
CHAPTER 5: Using Your Tape Drive SDLT 220 and SDLT 320 Product Manual 5.3 Updating the Firmware When you need to update the firmware in a drive, you can do it either of two ways: • Build a firmware image tape; this tape can be used in either a manual firmware update or in a Library setting. • Update the firmware over the SCSI bus. Both of these approaches are described briefly in the following subsections.
SDLT 220 and SDLT 320 Product Manual CHAPTER 5: Using Your Tape Drive 5.3.2 Making a FUP/CUP Tape SDLT Update is a tool that allows you to update a drive’s firmware (using the SCSI bus), or to create a code update (CUP/FUP) tape for an SDLT drive. SDLT Update is available on Quantum’s web site, http://www.quantum.com. Follow the path Support =>Drivers and Software and download the SDLT Update package. For detailed instructions about how to make the tape, refer to that tool’s built-in online help. 5.3.
CHAPTER 5: Using Your Tape Drive SDLT 220 and SDLT 320 Product Manual NOTE: The Firmware Upgrade will fail the microcode update process if the firmware personalities do not match; this will be noted in the history log, along with the reason for the failure. 7. Wait several minutes for the update process to complete. The Amber and Green LEDs will blink the entire time that memory is being updated. 8. When the update is complete, the drive resets itself and goes through POST.
SDLT 220 and SDLT 320 Product Manual CHAPTER 5: Using Your Tape Drive 5.4 Cleaning the Tape Mechanism This section discusses the SDLT cleaning tape, maintenance considerations, and important compatibility issues you need to be aware of.

APPENDIX A Super DLTtape I Data Cartridge By following general handling procedures, conducting careful visual inspections of data cartridges on a regular, ongoing basis, and making sure that data cartridges are stored within their environmental limits, you will greatly reduce any chance that you will experience problems with your data cartridges or cause damage to your SDLT system. Respect your media as much as you do your data.
APPENDIX A: Super DLTtape I Data Cartridge SDLT 220 and SDLT 320 Product Manual A.1 Recognizing Quantum-authorized Super DLTtape Data Cartridges From the outside, the Super DLTtape I data cartridge looks very similar to the DLTtape IV data cartridges. However, the Super DLTtape I data cartridge is easy to recognize; it has a different color (green) than the DLTtape IV data cartridge (charcoal) and contains a distinctive pattern molded into the shell.
SDLT 220 and SDLT 320 Product Manual APPENDIX A: Super DLTtape I Data Cartridge A.2 Data Cartridge Handling Guidelines Ensure that your tape backup solution performs reliably by following these general handling guidelines: • Always keep each data cartridge in its protective plastic case when it is not in the tape drive. • When carrying data cartridges in their cases, always orient the cases so that the grooves in the cases interlock. This prevents the cases from slipping apart and falling.
APPENDIX A: Super DLTtape I Data Cartridge SDLT 220 and SDLT 320 Product Manual • A dropped cartridge may have dislodged, loosened, or damaged internal components. If you drop a cartridge, give it a thorough visual inspection, as described in “Data Cartridge Inspection Procedure” on page A-4. • Never apply adhesive labels or “sticky” notes on the top, side, or bottom of your Super DLTtape I data cartridge.
