autoload_master-frame6.fm Page 4 Monday, December 29, 2003 9:39 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 37). This will provide information about the SCSI bus and the SCSI IDs in use.
autoload_master-frame6.fm Page 5 Monday, December 29, 2003 9:39 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 11 Monday, December 29, 2003 9:39 AM Step 1: Check the autoloader’s SCSI ID Note 1 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 29 Monday, December 29, 2003 9:39 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 31 Monday, December 29, 2003 9:39 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 32 Monday, December 29, 2003 9:39 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 38 Monday, December 29, 2003 9:39 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 39 Monday, December 29, 2003 9:39 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 40 Monday, December 29, 2003 9:39 AM How should the SCSI bus be configured?
