1. Introduction The Certance DAT 72 and DDS-4 tape autoloaders are fully integrated, intelligent, multi-cartridge tape systems that support the (Digital Data Storage) DDS-2 (DDS-4 autoloader only), DDS-3, DDS-4, and DAT 72 (DAT 72 autoloader only) 4mm tape formats. They include a magazine that can accommodate up to six (6) data cartridges. These autoloaders are an internal or standalone desktop subsystem that connects to a host system using an LVD 2 68-pin shielded SCSI cable.
Introduction Capacity and Transfer Rates Capacity and Transfer Rates The Certance DAT 72 and DDS-4 autoloaders provide the following capacities and sustained data transfer rates, depending upon the type and length of tape media used. These capacities and transfer rates are based on an assumed 2:1 data compression rate. Uncompressed (native) capacities are one-half these values. Table 1.

4. Operating Your Autoloader This chapter describes how to operate your autoloader.
Operating Your Autoloader Starting the Autoloader Starting the Autoloader Turn on all external SCSI devices attached to your computer before you turn on the computer. When the autoloader is first started, the following events should occur: 1. The Clean, Media, and Drive LED’s light up for two seconds, then start flashing. 2. The LCD display shows the current SCSI ID. 3.
Operating Your Autoloader Applying Labels Applying Labels When applying labels to a cartridge, observe the following precautions to prevent the cartridge from getting stuck in the autoloader: • Apply labels firmly, only in recessed label areas on the top side of the cartridge. • Do not let labels extend beyond label areas or fold over the edge of a cartridge. • Do not apply labels over other labels.
Operating Your Autoloader Ejecting a Cartridge or Magazine Loading a Magazine into the Autoloader CAUTION: Do not load a magazine if all the LED’s are flashing; this indicates that the autoloader is performing a Power On Self Test (POST). 1. Make sure the autoloader is powered on and operating normally. 2. Hold the magazine so that the slot numbers are right-side-up. 3. Write-protect or write-enable the magazine as appropriate.
Operating Your Autoloader 5. Ejecting a Cartridge or Magazine The magazine is ejected. If there is no cartridge loaded in the autoloader mechanism, the magazine is ejected without delay. Forcing an Eject If you press the Eject button when the autoloader is busy, the autoloader will complete the current task before responding to the eject request. This way no data is lost.
Operating Your Autoloader Write-Protecting a DAT Cartridge and Magazine Write-Protecting a DAT Cartridge and Magazine Write-protecting a DAT cartridge protects the data on the cartridge from being changed, overwritten, or deleted. To write-protect a cartridge, slide the write-protect tab on the back of the cartridge to the open position. To write-enable the cartridge, slide the write-protect tab so the hole is closed. Write enabled Write enabled Write protected Write protected Figure 11.
Operating Your Autoloader Cleaning the Tape Path Cleaning the Tape Path If excessive magnetic dust or debris collects at one or more of the tape heads, the autoloader may not be able to read from or write to tape, or may experience excessive errors. When the cleaning threshold is exceeded, the autoloader will display the cleaning request in two ways: • The LCD display will show the message “CLEANING REQUIRED.” • The Clean LED will remain ON continuously.
Operating Your Autoloader Preparation for Shipping Each time the cleaning cartridge is loaded, a new, unused portion of cleaning tape is advanced over the entire tape path. The drive does not rewind a cleaning cartridge. After about 30 cleaning cycles, the entire tape is used up, and you must purchase a new cleaning cartridge. If you insert a cleaning cartridge that has been used up, the cleaning cycle will not be carried out.
Operating Your Autoloader Preparation for Shipping 6. Wait 5 seconds. The LCD screen will again display the message “NO MAGAZINE.” After another 5 seconds, the LCD will display the message, “DOOR LOCKED.” 7. Switch off the autoloader. 8. Tap the door to make sure it has been successfully locked. The door is now locked in the closed position and the autoloader is ready to be packed and shipped. The door is automatically unlocked when the autoloader is restarted.
5. Understanding the Drive LEDs This chapter describes the LEDs on the front panel of the DDS-4 and DAT 72 autoloader. These LEDs provide information about both normal and error conditions.
Understanding the Drive LEDs LED Summary Eject Button You can use the Eject button to eject the magazine or to unload a cartridge from the drive. After pressing the Eject button, you must press the Enter button to confirm your request. Select Button You can use the Select button to select individual cartridges by their slot numbers (1 through 6), to scroll through items from menus on the LCD display, and to access loader menus if no magazine is installed.
Understanding the Drive LEDs Clean LED Clean LED The Clean LED indicates whether a drive needs to be cleaned. Table 8. Clean LED LED Status Description ON continuously Drive requires cleaning. Use only an approved DDS cleaning cartridge. Flashing slowly (approximately Tape cartridge in use has exceeded a predefined soft-error threshold. ON 2 seconds, OFF 1 second) This signal is a warning only and does not indicate that data has been compromised.
Understanding the Drive LEDs Drive LED Drive LED The amber Drive LED lets you know when data is being read from or written to tape. It also informs you when a hardware fault occurs. Table 10. Drive LED LED Status Description ON continuously The drive is reading or writing the tape (SCSI or tape movement is present). Flashing rapidly A hardware fault occurred. If the fault occurs immediately after powering on the drive, the Power On Self Test (POST) switch (switch 4) is enabled and a POST has failed.

Operating System DIP Switches Configuration for Novell Environment There are two possible ways to configure the DAT 72 and DDS-4 autoloader to work with the NetWare native backup application, depending on which tape driver you use.
Configuration for Novell and UNIX Operating System Configuration Digital UNIX Version 4.0 and Later With Version 4.0 of the Digital UNIX operating system, DEC introduced a new method of configuring the CAM SCSI driver. Modify the file /etc./ddr.dbase as follows: 1. Look through the file and locate the database entry for the DEC TLZ07 DAT drive 2. Copy this entry and paste it later in the file, taking care to maintain the file syntax. 3. Modify this new entry as shown below.
Configuration for Novell and UNIX Operating System Configuration (struct pt_info *)ccmn_null_sizes, SZ_NO_BLK, (DEC_MAX_REC - 1), &tlz07_dens, NO_MODE_TAB, SZ_NO_FLAGS, NO_OPT_CMDS, SZ_READY_DEF, SZ_NO_QUE, DD_REQSNS_VAL | DD_INQ_VAL, 36, 64 }, 4. Rebuild the kernel using the doconfig script. Then reboot the system.
Configuration for Novell and UNIX Operating System Configuration Solaris 2.x 1. To configure Solaris 2.x for compatibility with the DAT 72 or DDS-4, add the following lines to the file st.conf in the directory /kernel/drv. tape-config-list= “ARCHIVE Python”,“Iomega DAT Drive”,“ARCHIVE Python DAT”; ARCHIVE Python DAT = 1,0x34,0,0xd639,4,0x00,0x8C,0x8C,0x8C,3; 2. After modifying the file st.conf, you must reconfigure the kernel by booting the system using the boot -r command.
Configuration for Novell and UNIX Operating System Configuration Irix V6.x through V6.5 To configure Irix 6.x-6.5 to use a DAT 72 or DDS-4 autoloader, you must modify the files /var/ sysgen/master.d/scsi and /dev/MAKEDEV.d/TPS_base, as described below. After modifying these files you must rebuild the kernel. 1. Edit the file /var/sysgen/master.d/scsi and add one of the following entries, depending on your version of Irix: Irix V6.x through V6.
Configuration for Novell and UNIX Operating System Configuration Troubleshooting Installations on the SGI Platform Checking the Inquiry String It may be useful to confirm the autoloader’s inquiry string. This is done using the mt command. The following command line will retrieve the Inquiry string and other status data from the autoloader on SCSI bus 1, ID 6.
Configuration for Novell and UNIX Operating System Configuration immediately, SAM will create a new kernel, and automatically reboot the system. Once the system comes back up, the necessary drivers will be loaded, and the system will be able to use the tape drive. 8. If you had to shut down the system in order to physically connect the tape drive, re-enter SAM and repeat steps 3 through 6 above. 9. Choose the new tape drive. 10. From the Actions menu, choose Create Device Files. 11.
Configuration for Novell and UNIX 7. Operating System Configuration Exit SMIT. Controlling Data Compression under AIX After you run SMIT, device files will have been created for your new tape drive. Typical filenames are listed below: /dev/rmt0/dev/rmt0.1/dev/rmt0.2/dev/rmt0.3 /dev/rmt0.4/dev/rmt0.5/dev/rmt0.6/dev/rmt0.7 If you enter the configuration information specified in step 5 of the configuration process, devices rmt0, rmt0.1, rmt0.2 and rmt0.3 will cause the drive to write in compressed mode.
7. Troubleshooting This chapter provides suggestions for troubleshooting your drives in the unlikely event you encounter a problem with them.
Troubleshooting SCSI Termination Problems SCSI Termination Problems If the DDS-4 or DAT 72 autoloader is the last device or the only device in a SCSI chain, you must install a terminating plug on the unused SCSI connector. If the drive is the only SCSI device, attach the drive to the connector which is next to last on the SCSI chain and attach a multi-mode terminator to the last connector in the chain.
Troubleshooting 3. Backup Program Does Not Recognize Drive Check that the SCSI bus is terminated properly. Note that the DDS-4 and DAT 72 autoloaders do not provide SCSI termination and, therefore, should not be the last devices on a SCSI chain. Backup Program Does Not Recognize Drive If your backup application program does not recognize the drive: 1. Use the Windows Device Manager to determine whether the operating system has recognized the drive.
Appendix A: Loading Revised Firmware Your DDS-4 or DAT 72 autoloader includes permanently installed, electrically upgradeable flash memory. This memory allows qualified OEMs to revise DAT 72 and DDS-4 SCSI firmware quickly and easily. It also prolongs the life of the tape drive by allowing the drive to inherit leading technologies as soon as those technologies become available. This appendix describes how to load firmware onto your tape drive.
Loading Revised Firmware Using Firmware Cartridges cartridge and the drive LEDs blink in a progressive pattern. When the blinking pattern stops, the firmware upgrade operation is complete. WARNINGS: Once the firmware upgrade cartridge is inserted into the drive, no power interruption can occur while the firmware is loading. Do not power off the drive. If a power interruption occurs, the firmware may not be loaded correctly and the drive may not operate properly.
