InstallationinaMulti-Tape
BackupTray 1
Follow the instructions in this chapter to configure and install the DLT4000
tape drive in a Multi-Tape Backup Tray.
Installation
1. Determine your operating system using the uname -rs command.
Caution – For SunOS 5.4, 5.5, or 5.5.1 operating systems, you must perform the
procedures in Appendix A, "Modfiying 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.
3. Determine the SCSI device identifier (SCSI ID) for the tape drive.
To check for an available SCSI ID, enter probe-scsi-all at the ok
prompt. Use a SCSI ID that is not returned by this command. Tape drives
are usually set to a SCSI ID of 4 or 5. Write down the SCSI ID (and SCSI host
adapter identifier) for future use.
Note – Do not use SCSI ID 7; it is reserved for the host adapter.
4. Turn off the power to your system and then to 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.
Connect the cables as shown in Figure 1-1
Figure 1-1 Back of DLT4000 Tape Drive
Note – Although there are other switches and connectors on the tape drive,
they are inactive in Sun™ configurations.

7. Install new locking brackets and spacers if you are installing the tape
drive in a Multi-Tape Backup Tray that is in a Data Center Expansion
Cabinet.
a. Install new locking brackets on the Multi-Tape Backup Tray.
Figure 1-2 Installing New Locking Brackets on a Multi-Tape Backup Tray
b. Install spacers and screws on the other tape devices and filler panels to
make them flush with the DLT4000 tape drive.

8. Power on your peripherals and then your system.
Note – If your system starts to reboot, interrupt the reboot proces by pressing
the ‘Stop’ and ‘A’ keys together.
9. Reboot your system using the boot -r command.
10. Load a tape cartridge into the tape drive (see "Loading a Tape Cartridge"
on page 19).
Wait for the tape drive to fully load the tape cartridge.
Note – If all the LEDs on the right or left side of the tape drive front panel are
blinking, then the tape drive has failed its power-on self-test (POST). Go to
“Troubleshooting” on page 6.
11. Determine which remote number the tape drive has been mapped to.
a. Process the remote numbers in the /dev/rmt directory.
For example, a system with two tape drives (one connected to an internal
SCSI host adapter and one to an external host adapter) might look like:
b. Find the remote number that contains the controller and SCSI ID (st)
number for the tape drive you installed.
In the previous example, the remote number 0would be used for a tape
drive connected to SCSI ID 4 on SCSI host adapter at
dma@f,81000/esp@f,80000.

12. Verify that the system recognizes the tape drive.
•A correct response would resemble:
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.
•Incorrect responses include:
•No tape loaded or drive offline indicates there is no cartridge
in the drive or that the cartridge is not yet loaded. Install a cartridge or
wait for the cartridge load to complete and retry the mt status
command.
•No such file or directory indicates there is no tape drive
attached to that rmt (remote) number. Try another remote number.
•SCSI tape drive indicates the st.conf entry is incorrect. You must
edit the st.conf file and reboot until you no longer see SCSI tape
drive.
The Tape In Use LED should be lit, signifying that the drive is ready for use.
Go to Chapter 3, "Operation."
Note – If the tape drive does not complete POST, or if all the right- or left-side
LEDs blink repeatedly, go to “Troubleshooting” on page 6.

Troubleshooting
If the DLT4000 tape drive fails during POST or operation, use Table 1-1 to
determine the problem and the action to take.
Table 1-1 Troubleshooting
Symptom: Your system does not recognize the DLT4000 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.
Action: Try to unload the tape and reinitialize the drive by pressing the
Unload button, or turn the drive power off and then on again.
The right- or left-side LEDs stop blinking and the drive tries to
reinitialize. The LEDs should turn on steady again and go off if
the test succeeds.
If all right- or left-side LEDs still blink, the drive has a hardware
failure.
