HP StorageWorks DAT autoloaders can be connected to servers running under Windows®, NetWare, UNIX, Tru64 and Linux. Refer to the “HP StorageWorks Tape Software Compatibility” topic on our World Wide Web site (www.hp.
autoload_master-frame6.fm Page 4 Monday, December 29, 2003 9:28 AM How can I check the SCSI bus type and SCSI ID? For many operating systems, you can install HP Library & Tape Tools from www.hp.com/ support/tapetools and run the “Install Check” to check your server’s current SCSI configuration (see page 43). This will provide information about the SCSI bus and the SCSI IDs in use.
autoload_master-frame6.fm Page 5 Monday, December 29, 2003 9:28 AM Backup software and drivers Backup software For optimum performance it is important to use a backup application that is appropriate for your system’s configuration. In a direct attach environment, where the autoloader is attached to a standalone server, you can use backup software that is designed for a single server environment. In network configurations you will need backup software that supports enterprise environments.

autoload_master-frame6.fm Page 9 Monday, December 29, 2003 9:28 AM Checking the SCSI connection Use the following questions to help you check your SCSI connection. As long as you have a spare drive bay in your server you should have a spare connection on the internal SCSI bus. You need to ensure it is the correct SCSI bus type. If you answer ‘Yes’ to all these questions, you are ready to install your autoloader. If you answer ‘No’, you will probably need to purchase and install additional items.

autoload_master-frame6.fm Page 11 Monday, December 29, 2003 9:28 AM Step 1: Check the autoloader’s SCSI ID Note Your HP StorageWorks DAT autoloader is shipped with a default SCSI ID of 5. Each device on the SCSI bus must have a unique SCSI ID number. The autoloader can be assigned any unused ID between 0 and 15. Do not use SCSI ID 7, which is reserved for the SCSI controller. SCSI ID 0 is typically assigned to the boot disk and should also not be used unless the autoloader is on a dedicated SCSI bus.

autoload_master-frame6.fm Page 17 Monday, December 29, 2003 9:28 AM Step 4: Prepare the mounting bay Warning To avoid personal injury or damage to the server or autoloader, ensure that the server is disconnected from the mains power supply while you install the drive. Caution Static electricity can damage electronic components. Always wear an antistatic wriststrap if one is available. If not, after you have disconnected power from the server and removed the cover, touch a bare metal part of the chassis.
autoload_master-frame6.fm Page 18 Monday, December 29, 2003 9:28 AM The diagram illustrates metal rails for use with a legacy HP ProLiant server. Other servers have different mounting hardware requirements. Please refer to your server documentation. Omit this step if your server does not require mounting hardware.
autoload_master-frame6.fm Page 19 Monday, December 29, 2003 9:28 AM Step 5: Attach mounting hardware If your server requires special rails or other hardware to install the autoloader, mount them on the autoloader in this step. If your server does not require special mounting hardware, proceed to “Step 6: Attach Ycable and install drive” on page 21 now. HP ProLiant servers Different models of server require different mounting methods. • Some HP ProLiant servers require mounting rails.

In stacker mode, the loaded cartridge is used first; when it is full, or the host server sends an UNLOAD command, the autoloader replaces it with the cartridge from the next highest numbered slot in the magazine. See page 29 for more information about autoloader modes.
autoload_master-frame6.
autoload_master-frame6.fm Page 35 Monday, December 29, 2003 9:28 AM Use the correct media In order to maximize drive and media reliability, normally use the autoloader to provide one week's backup per magazine. Ideally, use five cartridges and one cleaning cartridge in each magazine. This allows you to perform a full backup, up to 40 (DDS-4) GB or 72 (DAT 72) GB each working day, and ensures that the tape heads are cleaned once a week. For best performance we recommend HP branded media.
autoload_master-frame6.
autoload_master-frame6.fm Page 37 Monday, December 29, 2003 9:28 AM To clean the tape heads HP recommends weekly cleaning of the autoloader using an HP cleaning cartridge (part number C5709A). Do not use swabs or other means of cleaning the heads. The cleaning cartridge uses a special tape to clean the tape heads. A cleaning cartridge can only be used 50 times or as instructed on the cartridge packaging. Always place a check mark in a box each time you use the cartridge to clean the drive.
autoload_master-frame6.fm Page 38 Monday, December 29, 2003 9:28 AM Handling cartridges • Do not touch the tape media. • Do not attempt to clean the tape path or tape guides inside the cartridge. • Do not leave cartridges in excessively dry or humid conditions. Do not leave cartridges in direct sunlight or in places where magnetic fields are present (for example, under telephones, next to monitors or near transformers). • Do not drop cartridges or handle them roughly.
autoload_master-frame6.fm Page 39 Monday, December 29, 2003 9:28 AM Register your autoloader Once you have installed and tested your HP StorageWorks DAT autoloader, please take a few minutes to register your product.

autoload_master-frame6.fm Page 41 Monday, December 29, 2003 9:28 AM Using HP OBDR Compatibility HP One-Button Disaster Recovery is a standard feature on all HP StorageWorks DAT autoloaders. However, it can only be used with specific configurations and will only recover the server to which the autoloader is directly connected. To check whether your system (hardware, operating system and backup software) is OBDRcompatible, please refer to our World Wide Web site www.hp.com/go/connect.
autoload_master-frame6.fm Page 42 Monday, December 29, 2003 9:28 AM Testing for compatibility We recommend that you perform a full disaster recovery immediately after installation—if possible, onto a blank hard disk. If you do not have a blank hard disk and do not want to overwrite your system, you can safely cancel the disaster recovery process at step 3 in the following procedure. Refer to our connectivity web site (www.hp.com/go/connect) for more information about suitable backup applications.

autoload_master-frame6.fm Page 44 Monday, December 29, 2003 9:28 AM Optimizing performance Various factors can affect autoloader performance, particularly in a network environment or if the drive is not on a dedicated SCSI bus. If your autoloader is not performing as well as expected, consider the following points before contacting HP Support at www.hp.com/support. • Is the autoloader connected to a suitably-rated built-in SCSI bus or HBA, see “Why is the SCSI bus type important?” on page 3.
autoload_master-frame6.fm Page 45 Monday, December 29, 2003 9:28 AM Troubleshooting The first step in problem-solving is establishing whether the problem lies with the cartridge, the drive, the host server and its connections, or with the way the system is being operated. Most modern SCSI host bus adapters locate and display attached devices when the system is booting up. On Windows systems, if you swap or connect a product when your system is running, you will need to reboot the system.
autoload_master-frame6.fm Page 46 Monday, December 29, 2003 9:28 AM How should the SCSI bus be configured?
