Installation Chapter 1 – Installation Installation This chapter describes installation and configuration of the A3542A DDS-3 tape drive, including the following: 1. Preparing to install the device. 2. Peripheral upgrade rules. 3. Setting the configuration switches. 4. Setting the SCSI address. 5. Installing the device. — HP 3000 Series 9xx — HP 9000 Series 7xx, 8xx, and D/E/F/G/H/I/K/L/C Series — HP 9000 V-Class 6. Configuring and verifying the device.
1. Preparing to install the device A. Observe antistatic precautions. The device contains electronic components which can easily be damaged by small amounts of static electricity. To avoid damage, use a grounding wrist strap during installation. B. Inspect the items for physical damage. If any items are missing, contact your Hewlett-Packard representative. C. Record information. Record the device’s serial number. Record the SCSI bus and SCSI address to be used during installation.
Refer to your system installation manual for instructions and guidelines for internal peripheral installation. For V Class servers, see the Service Manual, HP 9000 V Class Server (Part No. A3725-90006). 3. Setting the configuration switches for data compression and MRS There is an eight-switch DIP switch on the bottom of the tape drive. Use switches 1, 2, and 3 to set the drive’s data compression and Media Recognition System (MRS) characteristics.
• Use switch 3 to configure the drive’s response to DDS MRS tapes. The Media Recognition System (MRS) is a method by which a tape drive can recognize a data-grade tape. The tape has a series of stripes on its transparent leader tape which the drive can detect. By default, the drive treats a non-Media Recognition System tape as read-only and will not write data to it. However, it is possible to switch the recognition system off using the configuration switches on the underside of the tape drive.
Installation 4. Setting the SCSI address To set the tape drive’s SCSI address, see the figure below. The default address is set to 0 for Series 800 systems and 3 for Series 700 systems. For V Class servers, the SCSI ID default is set to 1. Note Your tape drive firmware may be corrupted by assigning to a tape mechanism a SCSI ID previously assigned to another device. SCSI address jumpers Back of tape drive The SCSI address jumpers are shown below. Set the jumpers for one of the values shown below.
5. Installing the device HP 3000/9x9KS and HP 9000 Models K100/K200/K400 Use the manual HP 3000/9x9KS and HP 9000/Kx00 Internal Peripherals Upgrade Guide (Part No. A237590008) to install the device in the system unit. See the installation manual for your system for installation instructions for internal peripherals. For V Class servers, see the Service Manual, HP 9000 V Class Server (Part No. A3725-90006).
Installation 6. Configuring and verifying the drive Configuring and verifying for HP-UX References: • • System Administration Tasks manual for HP 9000 Series 800 Computers (B2437-90006) Installing Peripherals manual (B2437-90005) The tape drive will auto-configure on HP-UX systems, version 9.04 or later. When the operating system reboots, it determines that the DDS-3 tape drive has been installed, and installs the correct software device file to communicate with the tape drive.
Add the transparent manager Using the SCSI address of the tape drive, enter the following to add the transparent manager to the path. Use the SCSI address the tape drive was set to during installation. This example assumes the SCSI address is 0. io>APATH PATH=52.0 ID=PSEUDO Add the tape device Logical Device Number (LDEV) To add the device to the configuration, the Logical Device Number (LDEV) is used. The example assumes the LDEV address is 0 and the MPE/iX ldev number is 8. io>ADEV LDEV=8 PATH=52.2.
Installation Reboot with the new configuration Shut down the system by entering: CNTRL-A The cursor will return to the first column in the next line. Now enter: SHUTDOWN and press the RETURN key. When the system is completely shut down, it will respond: Shutdown of operating system complete. Now the system can safely be powered down or rebooted. Reboot the system by entering: START NORECOVERY Create a System Load Tape (SLT) This is an optional procedure.

Chapter 2 – Operation Operation Operation This chapter describes the features and operations of the DDS-3 tape drive, including the following: • • • • • • Features Front panel Operating the tape drive Handling and storing tape cartridges Cleaning the tape heads Backup routines Operation 2-1
Features The HP A3542A DDS-3 tape drive is a storage device which uses 4 mm DDS certified cartridge tapes. Some features include • • • • • Up to 12 gigabytes storage capacity (uncompressed mode) Read and write compatibility with DDS-1 and DDS-2 tapes 5 1/4 inch, half-height form factor Industry leading performance and reliability Built-in self-test diagnostic routines HP DDS tape drives are designed for optimum performance with HP’s DDS media. Use of HP media assures maximum reliability and performance.
Operating the tape drive Once the system is powered on, normal tape drive operation consists of loading and unloading tape cartridges. Power on • • • The device is powered on when the host system is powered on. The tape drive automatically begins a self-test. The green Tape LED flashes slowly during the test. When the self-test is complete, normal tape operations can begin. Loading tape cartridges • • • To write to the tape, set the write-enable tab.
• Put the tape cartridge in its box and store it in a safe place. Note Some application software can be configured to prevent unloading a tape until the program ends. If the cartridge will not eject, check the software. Forcing a tape cartridge to eject Caution Data may be irretrievably lost if a tape is forced to eject. There may be a need to unload a tape cartridge immediately, even if data is lost. To do this, force the tape cartridge to eject.
Handling and storing tape cartridges Tape Cartridge Do’s • • • • • Always store the cartridge in its protective case. • • • Keep the cartridge away from magnetic sources. • Write on the label before adhering the label to the cartridge. Always remove the old labels before adhering new ones. • Be consistent with the type of media used. The heads need to adjust to the characteristics of each different kind of media. Always keep the cartridges in a clean environment.
Temperature Only use cartridges at temperatures between 5° C (40° F) and 40° C (113° F). The cartridges can be stored at temperatures down to -40° C (-40° F), but Hewlett-Packard does not recommend this practice. If the cartridges are exposed to temperatures outside the operating limits, stabilize them before using them. Do this by leaving the cartridge in a room at operating temperature for a minimum of two hours.
Cleaning the read/write heads Use the following table as a guide for cleaning the tape’s read/write heads. You should also clean the tape heads if the Clean/Attention LED is lit. Caution Only use an HP Cleaning Cartridge (HP 92283K) to clean the tape heads. Do not use swabs or other means of cleaning the heads. The cleaning requirements for the DDS-3 tape drives are significantly different from those for HP’s previous DDS products.
Backup routines Your backup routine depends on how frequently the data changes, how extensive the changes are, and how valuable the data is. It is essential that you follow a routine, so data backup is regular and trouble-free. The following three models present routines which are commonly used. In each model, a “‘set”’ of cartridges is the smallest number of tapes that will hold a full or partial backup.
Model 3: Monthly and weekly rotation with daily backup The backup model which offers optimum data protection uses six full backup sets (three monthly and 3 weekly), and four sets for daily partial backups. This model is recommended if you compile large quantities of data where loss would be disastrous. It also provides the best method of securing data from software viruses. The four sets of tapes for daily partial backup are labeled Monday, Tuesday, Wednesday, and Thursday as in model 2.
For example, if it happens that you use 3 cartridges each day, then cleaning is required every three weeks. In that case, if you are using backup model 3, you should store a cleaning cartridge with one particular set of weekly full backup cartridges, so the heads are cleaned every time that set is used.
Chapter 3 – Service Service Service This chapter describes service and troubleshooting procedures for the DDS-3 tape drive, including the following: • • • • • • • Maintaining the device Troubleshooting Preparing for a service call Reshipment guidelines Media specifications Required patches Specifications Service 3-1
Maintaining the device The device is designed to give years of trouble-free service. With regular maintenance, the drive should produce consistent results with minimal errors. This tape drive is designed for best performance with HP DDS-3 tapes. Case studies have shown that tape mechanism failures can be reduced by 80% using a strict tape management and cleaning regimen. Environmental limits The performance and reliability of the drive depend on the operating environment.
Preventive maintenance The tape drive requires regular preventive maintenance, which consists of cleaning the tape drive’s read/ write heads with a cleaning cartridge. Clean the heads regularly and also any time the Clean/Attention LED is flashing. The frequency of cleaning varies according to how much the tape drive is used.
Troubleshooting The first indication of a problem with the tape drive will probably be in the form a message from the application using the tape drive. If a problem occurs, check the tape drive’s status LEDs. Condition No LEDs on Tape LED is steady green Tape LED is flashing green Clean/Attention LED is flashing amber Probable Cause Action No tape in drive. Insert a tape in the drive. No power to drive. Be sure the system is powered on. Indicates normal activity.
SupportWave and other troubleshooting software The computer may be supplied with a tool called Support Tools Manager, which a system administrator can use to troubleshoot problems. Find out more about using Support Tools Manager in the manual Support Media Manual (part number 92453-90010). The system may also include other on-line or off-line troubleshooting utilities to aid in the diagnosis of the drive.
Preparing for a service call If the tape drive requires service, there are several things to do to help the Hewlett-Packard service provider identify and solve a problem quickly. Do the following before calling for assistance. If you have a V Class servers, see your service contract for information needed for service calls.
