Chapter 1 Introduction This document describes the HP DDS-2 (HP model number C1539A) drive, its installation, operation, troubleshooting, and removal/replacement procedures. This chapter introduces the DDS-2 drive and contains the following information: General description of the drive Major features of the drive Preparing to install the drive Preparing the system Powering off the workstation and any peripherals.
Introduction General Description The HP DDS-format drives have been developed by Hewlett Packard for data storage drives that build on DAT technology. The DDS-2 drive has 4-GB native capacity, yielding up to 8 GB of stored data and has data compression functionality. Figure 1–1 shows the DDS-2 drive.
Introduction Major Features of DDS Drives The DDS-1 format incorporates error correction techniques used in audio DAT drives with additional techniques specifically designed to provide the integrity of data necessary for computer use. These extra methods of error detection and correction are as follows: C3 ECC, a third level of Error Correction Code providing correction across frames within groups.
Introduction DDS-2 Drive The HP C1539A implements the DDS-2 format. This includes all of the features of the DDS-1 and DDS-DC formats, plus the ability to read and write with much higher capacity as follows: Reads and writes using DDS-1 and DDS-DC formats when using DDS-1 media (60 m and 90 m).

Introduction Preparing to Install the DDS-2 Drive The following information describes how to prepare the DDS-2 drive for installation. Tools Required The following tools are needed to install the DDS-2 drive: #2 Phillips screwdriver Small needle-nose pliers T10 torx wrench Verifying Kit Contents Verify that the kit contains one of each of the following: DDS-2 drive (manufacturing part number 0950–2658)
Introduction Setting the SCSI-2 Address The DDS-2 drive must have a unique SCSI-2 target address. The DDS-2 drive’s jumpers are set at the factory to the SCSI-2 default address of 3 as shown in Figure 1–3. You must also ensure that the Operation Mode jumpers are set for correct drive operation, as shown in Figure 1–4.
Introduction If you need to change the Operation Mode switches, locate the switches on the un- derside of the DDS-2 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.

Introduction 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, with a maximum sustained transfer rate of 5.0 MB/second.
Introduction Powering Off the Workstation and any Peripherals To power off the workstation and any peripherals, perform the following steps: 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.
Introduction Adding or Removing the DDS-2 Drive Bezels or Expansion Brackets Depending on the size of the drive opening in your system, you may need to add or remove a bezel or expansion brackets to ensure that your DDS-2 drive fits in your system.
Introduction To remove a bezel from a drive, use a straight blade screwdriver to lift the bezel tabs from the sides of the drive. Refer to Figure 1–6. Figure 1–6. Removing a Bezel from the DDS-2 Drive To add expansion brackets to the drive or to remove them, use a T10 torx wrench to either tighten or remove the four torx screws that hold each expansion bracket to the drive.
Introduction You are now ready to begin the hardware installation of your DDS-2 drive. The step-by-step instructions for installing the drive are found in the Owner’s Guide that came with your workstation. 1–17...
Chapter 2 Using the DDS-2 Drive This chapter provides the following information on using your DDS-2 drive: DDS-2 drive configuration Controls and features of the DDS-2 drive Using the DDS-2 drive To verify HP-UX system operation, see the Owner’s Guide that came with your workstation.
Using Your DDS Drive Your DDS-2 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-2 drive with the operating system. To find out more about creating and using device files, the the Owner’s Guide that came with your system.
Using Your DDS Drive LEDs The front panel has two colored LEDs: the Tape Light and the Clean/Attention Light. The Tape Light flashes green to show activity (loading, unloading, reading, and writing). Steady green means a cartridge is loaded. The Clean/Attention Light flashes amber to indicate head cleaning is needed or a cartridge is near the end of its life.
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.
Using Your DDS Drive 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.
Using Your DDS Drive Using the DDS-2 Drive This section describes how to perform tasks with your DDS-2 tape drive. Loading and Unloading a Data Cassette Follow these steps to load and unload a data cassette from the DDS-2 tape drive: Turn on power to the tape drive.
Using Your DDS Drive Push the data cassette about three quarters of the way into the drive. The drive automatically pulls the data cassette the rest of the way in. When the LEDs on the front of the drive stop flashing, the drive has loaded the data cassette. To remove the data cassette, press and release the eject button on the front of the drive, as shown in Figure 2–3.
Using Your DDS Drive For information on using device files or archiving data to or from the DDS-2 drive, see the Owner’s Guide that came with your workstation. Media Interchangeability Restrictions If you interchange media between DDS-format tape drives, note that data cassettes with compressed data can only be read by tape drives that have data compression capabilities.
Using Your DDS Drive Ordering Information To order Hewlett-Packard data cassettes and cleaning cassettes for use in your DDS-2 tape drive, use the following order numbers: HP92283A Box of five 60-meter DDS data cassettes HP92283B Box of five 90-meter DDS data cassettes...
