CHAPTER 1 Installation This chapter describes how to install, configure, and troubleshoot the DLT8000 tape drive. Installing the Tape Drive ▼ To Install the Tape Drive 1. Determine your operating environment using the uname -rs command. Caution – If your system uses the Solaris 2.5, 2.5.1, 2.6, or 2.7 operating environments, you must perform the procedures in Appendix A before proceeding. 2. Shut down the operating environment. Use either the init or shutdown command.
4. Power off your system and then your peripherals. 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.
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.
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.
A correct response would resemble: #mt -f /dev/rmt/3 status Other tape drive: ___sense key (0x0)= No Additional Sense residual= 0 retries= 0 ___file no= 0 block no= 0 # Other tape drive on the first line of the output indicates that the tape drive is correctly recognized. If one of the following error messages is displayed, troubleshoot as follows: ■ ■ ■ No tape loaded or drive offline indicates there is no cartridge in the drive or that the cartridge is not yet loaded.
Troubleshooting If the tape drive fails during POST or operation, use Table 1-1 to identify the problem and determine what action to take. TABLE 1-1 6 Troubleshooting Symptom: Your system does not recognize the DLT8000 tape drive. Action: Make sure that: • The SCSI ID is unique. • The SCSI 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.
CHAPTER 2 Operation This chapter gives details of the basic operation of the Sun StorEdge DLT8000 tape drive, and provides a description of the front panel LED indicators. This chapter is organized as follows: ■ ■ ■ ■ “Front Panel Controls and LED Indicators” on page 7. “Tape Cartridge” on page 10. “Selecting Density” on page 14. “System Diagnostic Support” on page 16. Front Panel Controls and LED Indicators W 2.6 rite Pr ote c ted 610 15.0.0/ .0 10 20.0 .0/1 Ta p In e Us e 5.0 2 350.0 .

On Compression mode is enabled. Off Compression mode is disabled. On You selected a density from the front panel. Off Density will be selected by the host.
Right Front Panel LEDs TABLE 2-2 Right Front Panel Led 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 “To Clean the Drive Head” on page 14). Off Cleaning is complete, or cleaning is unnecessary. On OK to use the cartridge insert/release handle. Off Do not use the cartridge insert/release handle. On POST is starting.
Tape Cartridge Label area Write-protect switch FIGURE 2-2 DLT Tape Cartridge The DLT8000 tape drive uses type III, IIIxt, and IV DLT tape cartridges. These tape cartridges contain 1/2-inch magnetic metal particle tape.
Write Protect The tape cartridge has a write-protect switch (FIGURE 2-1) to prevent accidental erasure of data. This switch can be set prior to or after inserting the tape cartridge into the tape drive. ■ To write protect a tape cartridge, move the switch to the left so that a small rectangle is visible. ■ To write enable a tape cartridge, move the switch to the right so that the rectangle is not visible.
Note – If a tape cartridge has been exposed to extreme heat or cold, stabilize the cartridge at room temperature for the same amount of time it was exposed (up to 24 hours). ▼ To Load a Tape Cartridge Into the Tape Drive 2 3 4 FIGURE 2-3 Loading a Tape Cartridge 1. Make sure that the Operate Handle LED is on (FIGURE 2-1). 2. Lift the cartridge insert/release handle (FIGURE 2-1). 3. Insert the cartridge into the tape drive.
4. Gently push the handle closed. The Operate Handle LED turns off and the Tape In Use LED blinks to show the tape is loading. When the tape is loaded, the Tape In Use LED turns on steadily. The tape is now ready for use. ▼ To Unload a Tape Cartridge From the Tape Drive 1 3 FIGURE 2-4 2 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. 1.
3. Remove the cartridge. 4. Push the handle closed. ▼ To Clean the Drive Head Caution – Use only a DLT Type III cleaning tape cartridge to clean the tape drive. The Use Cleaning Tape LED lights when the tape drive needs cleaning. 1. Load the cleaning tape cartridge into the tape drive (see “To Load a Tape Cartridge Into the Tape Drive”). 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.
Note – Blank tape cartridges do not have default densities. None of the density LED indicators on the front panel will light until data has been written to the tape. Table 2-4 shows the densities you can be select for the tape drive. TABLE 2-4 ▼ Selectable Densities Tape Type Selectable Densities (in Gbytes) III 2.6, 6.0, 10.0 native or 10.0 compressed IIIxt 15.0 native IV 20.0, 35.0/40.0 native or 20.0, 35.0/40.0 compressed To Select Density Using the Front Panel 1.
▼ To Select Density Using Software Commands 1. Choose a density specifier from Table 2-5. TABLE 2-5 Density Specifiers Cartridge Types and Capacities Density Specifiers Type IV l 35 Gbytes m 70 Gbytes h 40 Gbytes 80 Gbytes u 1 Type IIIxt Type III 15 Gbytes 10 Gbytes 30 Gbytes1 15 Gbytes 1 30 Gbytes1 20 Gbytes1 10 Gbytes 20 Gbytes1 1. Assumes a typical compression ratio of 2:1. The compression ratio may vary depending upon the type of data being compressed. 2.
APPENDIX A Modifying the st.conf File The Solaris operating environment recognizes all tape drives and autoloaders that were supported by Sun when your operating environment was released. If your system uses Solaris releases 2.5, 2.5.1, 2.6, or 2.7—all of which were released before the DLT8000 tape drive—you must modify the /kernel/drv/st.conf file so that your operating environment will recognize the DLT8000 drive. Note – No st.
Understanding the st.conf File The beginning of the st.conf file contains values you can use to configure thirdparty 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 environment will use to configure previously unsupported tape devices.
1. The information about the tape device that the operating environment “sees” when it “looks at” a tape device. 2. The information the operating environment outputs when queried about the tape device (by programs such as SunVTS diagnostic software). 3. A string that 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 semicolon.
▼ To Modify 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.
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. On the next line, add the following entry exactly as shown: QDLT8 = 1, 0x36, 4, 0x9639, 0x84, 0x85, 0x88, 0x89, 3; Note – All lines in this section end with semicolons. f. Save and exit the file. 4. Go to Step 2 on page 1 and continue the installation procedure. Appendix A Modifying the st.
