Installation 1 This chapter describes how to install, configure, and troubleshoot the DLT7000 tape drive. Installing the Tape Drive 1. Determine your operating system using the uname -rs command. ! Caution – For SunOS 5.5 or 5.5.1 operating systems, you must perform the procedures in Appendix A, “Modifying the st.conf File," before proceeding. 2. Shut down the operating system. Use either the init or shutdown command. See the man pages for these commands or the Solaris AnswerBook online documentation.
1 5. Prepare your system or enclosure for servicing. Follow the procedures in the service manual for your system or enclosure. 6. Install the tape drive. Refer to the procedures in your system or enclosure service manual. Install this drive as you would any full-height device. a. Connect the SCSI and power cables to the connectors on the back of the tape drive (Figure 1-1).
1 b. Set the SCSI ID. For systems or enclosures with a SCSI ID cable, install the SCSI ID cable as shown in Figure 1-2 and set the SCSI ID for the tape drive using the SCSI ID switch on the system or enclosure. SCSI ID connectors Figure 1-2 SCSI ID Connectors For systems or enclosures that do not have a SCSI ID cable, connect the jumpers as shown in Figure 1-3.
1 7. Power on your peripherals and then your system. Note – If your system starts to reboot, interrupt the reboot process by pressing the Stop and A keys together. 8. Reboot your system using the boot -r command. 9. Load a tape cartridge into the tape drive (see “Loading a Tape Cartridge” on page 13). Wait for the tape drive to fully load the tape cartridge.
1 11. Verify that the system recognizes the tape drive. #mt -f /dev/rmt/remote_number status • A correct response would resemble: #mt -f /dev/rmt/3 status Other tape drive: sense key(0x0)= No Additional Sense file no= 0 block no= 0 # residual= 0 retries= 0 Other tape drive on the first line of the output indicates that the tape drive is correctly recognized. The rest of the output does not matter.
1 Troubleshooting If the DLT7000 tape drive fails during POST or operation, use Table 1-1 to determine the problem and the action to take. Table 1-1 6 Troubleshooting Symptom: Your system does not recognize the DLT7000 tape drive. Action: Make sure that: • The SCSI ID is unique. • The SCSI data cable is not loose. • The SCSI bus is correctly terminated. • You have rebooted the system using the boot -r command. Symptom: All LEDs on the right- or left-side of the tape drive front panel blink.
2 Operation This chapter gives details of the basic operation of the DLT7000 tape drive, and the meanings of the front panel displays. For information about software commands, refer to the Solaris Handbook for SMCC Peripherals or the AnswerBook documentation for your operating system.

2 Left Front Panel LEDs The tape drive has seven left front panel LEDs (Figure 2-1). The LEDs are described in Table 2-1. Table 2-1 Left Front Panel LEDs LED State Operating Condition 2.6 On/Blinking 1 Tape is recorded in 2.6 Gbyte format 6.0 On/Blinking 1 Tape is recorded in 6.0 Gbyte format 10.0/15.0 20.0 On/Blinking On/Blinking 1 1 1 Tape is recorded in 10.0 or 15.0 Gbyte format Tape is recorded in 20.0 Gbyte format Tape is recorded in 35.0 Gbyte format 35.
2 Right Front Panel LEDs The tape drive has four right front panel LEDs (Figure 2-1). The LEDs are described in Table 2-2. Table 2-2 Right Front Panel LEDs LED State Operating Condition Write Protected On Tape is write-protected. Off Tape is write-enabled. On Tape is loaded and ready for use. Blinking Tape is in use. On Drive head needs cleaning, or the tape is bad (See “Using a Cleaning Tape Cartridge” on page 17). Off Cleaning is complete, or cleaning is unnecessary.
2 Beeper There is a short beep whenever you press the Select or Unload button. There is a long beep to indicate that the tape unload sequence is complete and that you can operate the cartridge insert/release handle. The Operate Handle LED should also be on. To prevent damage to the drive, wait for the long beep before opening the door.

Assumes a typical compression ratio of 2:1. The compression ratio will vary depending upon the type of data being compressed.
2 Handling and Storage ! Caution – Do not drop or bang the tape cartridge. This can displace the tape leader, making the tape cartridge unusable and possibly damaging the drive. Follow these guidelines when handling tape cartridges: • Do not forcibly remove a tape cartridge from the drive. If a cartridge is difficult to remove, reinsert the tape cartridge, wait for the tape cartridge to load, and then try to unload the tape cartridge again. • Do not use adhesive labels on the tape cartridge.
2 Loading a Tape Cartridge 2 3 4 Figure 2-3 Loading a Tape Cartridge To load a tape cartridge into the tape drive: 1. Make sure that the Operate Handle LED is on (Figure 2-1). 2. Lift the cartridge insert/release handle (Figure 2-3). 3. Insert the cartridge into the tape drive. 4. Push the handle closed. Note – To prevent handle failures, do not flip the handle closed. The Operate Handle LED turns off and the Tape In Use LED blinks to show the tape is loading.
2 Selecting Density You can select the density that the tape cartridge will record data by using the front-panel Select button or by using a software command. In either case, the new density does not take effect until a write from beginning of tape (BOT) is executed. Until then, the original density will be used. Note – Blank tape cartridges do not have default densities. The DLT7000 will not light any LEDs on the left-side of the front panel until data has been written to the tape.
2 Selecting Density Using Software Commands. To select the recording density by using software commands: 1. Choose a density specifier from Table 2-5.

2 Unloading a Tape Cartridge Figure 2-4 ! 1 2 3 4 Unloading a Tape Cartridge Caution – Remove a tape cartridge from the drive before turning off the host system power. Failure to remove a tape cartridge can result in cartridge and drive damage. To unload a tape cartridge from the tape drive: 1. Press the Unload button (Figure 2-4). The Tape in Use LED blinks as the tape rewinds. This may take between 17 seconds and two minutes. 2.
2 Using a Cleaning Tape Cartridge ! Caution – Use only a DLT Type III cleaning cartridge to clean the tape drive. When the Use Cleaning Tape LED lights: 1. Load cleaning tape cartridge into the tape drive. See “Loading a Tape Cartridge". Note – If the Use Cleaning Tape LED lights after you load the cleaning tape cartridge, cleaning has not been done because the cleaning tape cartridge is expired. Replace the cleaning tape cartridge. A cleaning tape usually lasts about 20 cleanings. 2.

Modifying the st.conf File A The Solaris software environment recognizes all tape drives and autoloaders that were supported by Sun when your operating system was released. If your system uses SunOS releases 5.5 or 5.5.1, which were released before the DLT7000 tape drive, you need to modify the /kernel/drv/st.conf file so that your Solaris software will recognize the DLT7000 tape drive. If you are familiar with this procedure, go to “Modifying the st.conf File” on page 22.
A Understanding the st.conf File The beginning of the st.conf file contains possible values that you might use to configure third-party or other unsupported tape drives. These values are divided into three sections: • • • tape-config-list Tape device identifiers Configuration values tape-config-list The line: #tape-config-list= indicates the start of values that the operating system will use to configure previously unsupported tape devices.
A 1. The information about the tape device that the operating system sees when it 'looks at' a tape device. 2. The information the operating system outputs when queried about the tape device (by programs such as SunVTS diagnostic software). 3. A string which acts as a pointer to values that will be used to configure the tape device. Note – The first two lines of the example end in commas. The last line in the example ends with a semi-colon.
A Modifying the st.conf File Read this entire procedure before editing the st.conf file. Note – The syntax is critical. Verify the placement of commas, semicolons, and beginning and ending quotation marks. 1. Become superuser. % su Password: # 2. Make a copy of the original st.conf file as a backup (st.conf.old). #cp /kernel/drv/st.conf /kernel/drv/st.conf.old 3. Edit the st.conf file. Using an editor, scroll through the st.conf file to the following line: #tape-config-list= a.
A Note – If multiple devices are enabled (lines uncommented) only the last uncommented line with this format must end with a semicolon. All previous lines with this format must end with a comma. d. Using the editor, continue to scroll until you come to the end of the “Configuration Values” section. The line will look something like: #WtQIC = 1,0x32,512,0x0624,1,0x00,0; e.
