Introduction  
Setting the SCSI-2 Address  
The DDS-3 drive must have a unique SCSI-2 target address. The DDS-3 drive jumpers  
are set at the factory to the SCSI-2 default address of 3, as shown in Figure 1–3. We  
recommend that you keep the default address, if possible.  
You must also ensure that the Operation Mode jumpers are set for correct drive operation,  
as shown in Figure 1–4. We ship the drive with the Operation Mode jumpers set to  
operate correctly with your system.  
CAUTION: SCSI tape drives are susceptible to mechanical and electrostatic  
shock. When handling a DDS-3 drive, always wear the static-  
grounding wrist strap that comes in the DDS-3 drive kit, and al-  
ways handle the drive carefully.  
Electrostatic charges can damage drives. To prevent such damage  
from occurring, observe the following precautions during unpack-  
ing and installation:  
D Stand on a static-free mat.  
D Wear a static strap to ensure that any accumulated electrostatic  
charge discharges from your body to ground.  
D Connect all equipment together, including the static-free mat,  
static strap, routing nodes, and peripheral units.  
D Keep uninstalled DDS-3 drives in their protective antistatic  
bags.  
If you need to change the DDS-3 drive address or operation mode, follow these  
instructions, referring to Figures 1–3 and 1–4:  
1. Locate the jumpers at the back of the DDS-3 drive.  
2. To change the jumper settings, use needlenose pliers to set the drive’s SCSI ID to an  
address that is not used by another SCSI device. Check that the other jumpers are set  
correctly.  
1–7  
Introduction  
3. If you need to change the Operation Mode switches, locate the switches on the un-  
derside of the DDS-3 tape drive. Switches 1 and 2 are used to configure the data  
compression operation mode. Switches 3 through 8 are used to specify drive connec-  
tivity and functionality according to host or customer requirements. The default set-  
ting is all switches ON.  
Address Jumpers  
To set the drive’s address, use the SCSI-2 address jumpers, and perform the following  
steps:  
1. Attach the static-grounding wrist strap by following the instructions on the package.  
Attach one end of the strap to the system chassis.  
2. Locate the address jumpers on the rear of the DDS-3 drive. Figure 1–3 shows the  
rear of the DDS-3 drive with the significant bits identified.  
3. Set the drive’s SCSI-2 target address to an address that’s not used by another SCSI-2  
device. Using Figure 1–3 as a guide, use needlenose pliers to set the jumpers. When  
finished, refer to “Preparing the System,” later in this chapter, for information on  
verifying the jumpers have been set correctly and your system sees the drive.  
NOTICE: Do not use SCSI-2 address 7 because the system’s SCSI-2  
controller uses address 7 by default. We advise that you do not use  
SCSI-2 address 6 because the root disk drive uses it.

3. Shut down the system.  
If you are running HP-UX under HP VUE, shut down your system according to the  
shutdown procedure described in the owner’s guide that came with your worksta-  
tion.  
If you are running HP-UX without HP VUE, shut down your system by typing the  
following command:  
RETURN  
#/etc/shutdown -h  
You must have superuser privileges to use the /etc/shutdown command. If you do  
not have superuser privileges, contact your system administrator.  
If your workstation is part of a cluster, refer to Managing Clusters of HP 9000 Com-  
puters for instructions on shutting down.  
SCSI-2 Connection and Termination  
Only single-ended SCSI-2 configuration is supported.  
Only unshielded connectors can be used.  
The DDS-3 drive does not support termination on the device itself. Normally, drives such  
as this are not required to be at the end of a bus, but if this is unavoidable, HP  
recommends using a feed-through SCSI terminator that plugs directly into the rear of the  
drive.  
1–12  
Introduction  
If you do not already have a SCSI terminator, you must order either terminator K2291  
(bale-lock style) or terminator C2904A (thumbscrew style).  
NOTICE: Use care when inserting and removing feed-through terminators to  
avoid damaging the end walls of the terminator and the drive.  
Powering Off the Workstation and Any Peripherals  
To power off the workstation and any peripherals, perform the following steps:  
1. Power off the workstation, using the power switch on the front of the workstation.  
CAUTION: Do not power off your workstation without first shutting down  
HP-UX. Powering off with HP-UX still running could damage the  
data on the disks associated with your workstation.  
If you are already at the boot-administration level (the level used to check the SCSI-2  
IDs), you do not need to shut down before powering off.  
If you accidentally rebooted HP-UX while determining the address settings, see  
“Preparing the System,” earlier in this chapter, for instructions on shutting down HP-UX.  
2. Disconnect the power cord from the rear of the workstation and the wall outlet.  
3. Power off any external peripherals attached to your workstation, and unplug their  
power cables from the wall outlet.

Controls and features of the DDS-3 drive  
Using the DDS-3 drive  
To verify HP-UX system operation, see the owner’s guide that came with your  
workstation.  
For more information on checking or reconfiguring the kernel for a device driver or file,  
see System Administration Tasks Manual: HP 9000 Series 700 Computers.  
2–1  
Using Your DDS Drive  
Your DDS-3 Drive Configuration  
Your HP-UX operating system comes with preconfigured device files and drivers. If you  
use these preconfigured device files and drivers, you won’t need to configure your  
DDS-3 drive with the operating system.  
To find out more about creating and using device files, see the owner’s guide that came  
with your system.  
Controls and Features of the DDS-3 Drive  
Your DDS-3 tape drive is either a 3 1/2-inch form factor, or a 5 1/4-inch form factor  
DDS-3 tape drive with data compression and a SCSI interface. It conforms to the DDS-3  
format standard for storing computer data. It’s a high-capacity, high transfer-rate device  
for data storage on tape.  
Figure 2–1 shows the LEDs and eject button of the DDS-3 drive.

Data Cassettes  
Media Life  
HP DDS data cassettes are currently specified to 2000 passes over any part of the tape  
under optimal environmental conditions (50% relative humidity, 22 degrees C). During a  
tape operation, any one area of the tape may have multiple passes over the heads. This  
translates into approximately 200 to 300 backups or restores.  
Under certain conditions, the life of your data cassette is less than 200 to 300 backups or  
restores. Replace your data cassettes after 100 backups or restores if your operating  
conditions meet any of the following criteria:  
2–3  
Using Your DDS Drive  
The relative humidity in your operating environment is consistently less than  
50%.  
You know that the backup software you are using makes multiple passes over  
sections of the tape during backups or restores.  
You notice that when you do backups and restores the tape stops and starts fre-  
quently.  
Cleaning the Tape Heads  
Clean the heads of your tape drive after every 25 hours of tape drive use or if the Media  
Wear (Caution) signal is displayed on the LED.  
NOTICE: Only use HP Cleaning Cassettes (HP92283K) to clean the tape  
heads. Do not use swabs or other means of cleaning the tape heads.  
Follow this procedure to clean the tape heads:  
1. Insert the cleaning cassette into the drive. The tape automatically loads the cassette  
and cleans the heads. At the end of the cleaning cycle, the drive ejects the cassette.  
2. Write the current date on the cleaning cassette label so that you know how many  
times you have used it. Discard the cleaning cassette after you have used it 50 times.  
Media Restrictions  
If you interchange media between other HP workstation DDS tape drives, note that data  
cassettes with compressed data can only be read by tape drives that have data  
compression capabilities. This includes data cassettes that contain both compressed and  
noncompressed data.  
Setting the Write-Protect Tab on a Data Cassette  
You can only store or change information on a data cassette when the write-protect tab is  
in the write position. So, before trying to write to the data cassette, make sure that the  
write-protect tab is in the write position, as shown in Figure 2–2.  
2–4  
Using Your DDS Drive  
Push tab right  
for write.  
Push tab

writeĆprotect.  
Figure 2–2. Setting the Write-Protect Tab on a DDS Tape  
To protect information on a data cassette from being overwritten, set the write-protect tab  
to the write-protect position, as shown in Figure 2–2.  
NOTICE: The write-protect tab should always be in the write position for  
transferring data to a cassette.

1. Insert the data cassette into the drive, as shown in Figure 2–3.  
Eject Button  
Figure 2–3. Loading a Data Cassette  
2–6  
Using Your DDS Drive  
2. Push the data cassette about three quarters of an inch into the drive. The drive  
automatically pulls the data cassette the rest of the way in. When the Tape LED on  
the left front of the drive stops flashing, the drive has loaded the data cassette.  
3. To remove the data cassette, press and release the eject button on the front of the  
drive, as shown in Figure 2–3. The Tape LED on the drive flashes on and off. Ten to  
twenty seconds later, the data cassette slides partway out of the drive. Remove the  
cassette from the drive.
