Switch Settings for Data Compression Operation Mode 1­10 Introduction Preparing the System Perform the following steps to prepare the system for the DDS-2 drive installation: 1. Determine the existing SCSI-2 address settings currently in use on your system by completing the following steps:. If you are using SONY-UX 9. X, enter the following at the prompt: /etc/ioscan -d scsitape RETURN 2. After a few moments the ioscan utility lists all of the SCSI I/O devices it can find. If there is a SCSI DDS drive in the list, its listing appears similar to the following: H/W Path Description Status ============================================== 2. 0. 1. 3. 0 scsi ok(nnnnnnnn) If you are using SONY-UX 10. X, enter the following at the prompt: /usr/sbin/ioscan -d stape RETURN After a few moments the ioscan utility lists all of the SCSI I/O devices it could find. The list appears similar to the following: H/W Path Description Status ============================================== 2/0/1. 3. 0 tape SONY C1533A 1­11 Introduction If you are using SONY-UX 10.

" 1­12 Introduction 3. Shut down the system. If you are running SONY-UX under SONY VUE, shut down your system according to the shutdown procedure described in the Owner's Guide that came with your workstation. If you are running SONY-UX without SONY VUE, shut down your system by typing the following command: # /etc/shutdown -h RETURN 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 SONY 9000 Computers 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. Figure 2­1 shows the LEDs and eject button of the DDS-2 drive. Tape Light Clean/Attention Light Eject Button Figure 2­1. DDS-2 Drive Controls and Indicators 2­2 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.

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: 2­3 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 frequently. 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. [. . . ] To prevent such damage from occurring, follow proper ESD precautions. Field Replaceable Units The following components are authorized for field replacement. Description DDS-2 Part Number C1533A­69203 Powering Off the System Before performing the removal/replacement procedures, observe the following precautions: 1. 3. Refer to the Owner's Guide that came with your system for the procedures to power off the system. Unplug the system unit power cord and the power cords of any peripheral devices from the power source. [. . . ]
