About this guide
1 Before you start In • • • • this chapter: “HP StorageWorks DAT models” on page 13 “Which operating systems are supported?” on page 14 “Supplied cables” on page 14 “Using the HP StorageWorks Tape CD-ROM” on page 16 HP StorageWorks DAT models This guide describes how to install and operate the following HP StorageWorks DAT SAS tape drive models: • HP StorageWorks DAT 320 • HP StorageWorks DAT 160 For a detailed product specification, please refer to our World Wide Web site (http://www.hp.com). 1.
1. Clean LED 4. Ready LED 2. Tape LED 5. Eject button 3. Drive LED Figure 2 Front view of HP StorageWorks DAT 160 tape drive . Which operating systems are supported? HP StorageWorks DAT drives can be connected to servers running under Windows®, Linux and other major operating systems. Refer to the HP StorageWorks Tape Software Compatibility topic on our World Wide Web site, http://www.hp.com/go/connect/, for the most recent information about the operating system versions that are supported.
• If the host SAS controller has a mini-SAS connector, the supplied cable may be used to connect the tape drive. • If it has a SAS Infiniband-style connector, you must purchase a different cable.
CAUTION: HP SAS cables that connect to an internal port are split cables that contain four data paths, which normally support up to four hard disks. When used to connect to the host SAS controller, the split cable diverts one of these data paths to the tape drive, which means that the data path is no longer available for a hard disk drive. Take care if connecting to an internal port on the host SAS controller because you may lose the use of one of your hard disk drive bays.

Before you start
2 Drivers and backup software In this chapter: • “Install drivers ” on page 19 • “Upgrade backup software” on page 20 Install drivers Installing on Windows One driver is required in order to use HP StorageWorks DAT SAS tape drives. HPDAT is the HP Tape driver that works with all HP DAT products. It is regularly updated and is available on the HP StorageWorks CD-ROM or on the HP Support web site. However, certain software applications require you to use their own driver.
Either: Follow the on-screen instructions to search for the required on the CD-ROM. Or: 1. Cancel the wizard and insert the HP StorageWorks Tape CD-ROM. 2. Select the install drivers link on the CD-ROM. 3. Run the automated installer and follow the process to load the onto the system. 4. On completion of the installation the tape drive will be ready to use. Upgrade backup software For optimum performance it is important to use a backup application that is appropriate for your system's configuration.
3 Installing an internal DAT tape drive In • • • • • • this chapter: “Make sure you have the correct SAS cable” on page 21 “Prepare mounting bay” on page 23 “Attach mounting hardware” on page 24 “Install drive” on page 25 “Connect SAS and power cables” on page 25 “Secure the drive” on page 36 Please refer to “Installing an external DAT SAS tape drive” on page 37, if you are installing an external DAT tape drive.
1. Mini-SAS connector to server 4. Unused second branch on supplied cable 2. SAS connector to tape drive 5. Tie wrap 3. Power connector to server's power supply 6. Cover on unused SAS connector Figure 3 Supplied cable . The cable supplied with the tape drive is suitable for connecting to a dedicated HBA. An alternative option for HP ProLiant servers is to connect to the server's SAS controller.
CAUTION: HP SAS cables are split cables that contain four data paths, which normally support up to four hard disks. When used to connect to the host SAS controller, both the HP SAS Infiniband and the HP Mini-SAS split cables divert one of these data paths to the tape drive, which means that the data path is no longer available for a hard disk drive. Take care if connecting to the host SAS controller because you may lose the use of one of your hard disk drive bays.
Attach mounting hardware If your server requires special rails or other hardware to install the tape drive, mount them on the tape drive now. If your server does not require special mounting hardware, proceed to “Install drive” on page 25 now. Please check your HP ProLiant server documentation to ascertain the correct method of mounting, and to check whether mounting hardware is provided with the server or must be purchased separately. For more details about mounting hardware refer also to: http://www.hp.
Install 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. Similarly, touch a bare metal part of the drive before installing it. NOTE: If cable access for the tape drive bay is awkward, it may be easier to access power and other connections if the tape drive is installed in the top bay.
Supported cable configurations The internal tape drive may be installed in one of three configurations: • Connect to a dedicated HBA. If necessary, install an additional SAS HBA and HBA driver.. This is the recommended configuration and is suitable for HP and non-HP servers. It is described as Option 1 in this section. • Connect the tape drive to a spare SAS port on the host SAS controller. This cabling option is suitable for some HP ProLiant servers only. It is described as Option 2 in this section.
Figure 6 Selecting the correct cabling option for an internal tape drive . IMPORTANT: You may damage your server configuration, if you follow the wrong installation instructions when connecting to the host SAS controller. Always refer to http://www.hp.com/go/connect to find out which cabling option is appropriate for your combination of server and SAS host bus adapter. This will also advise about any possible impact on connectivity to disk drive bays.
Option 1: Connect to a dedicated HBA (all HP ProLiant servers and all non-HP servers) The following instructions are valid ONLY IF you have purchased and installed an additional HBA. Always refer to http://www.hp.com/go/connect BEFORE installing your tape drive. IMPORTANT: A SAS cable for connection to a dedicated HBA is supplied with the tape drive. This is a split cable, but the second branch is not required. Do NOT remove the tie wrap and cover on the spare connector. 1. If necessary, install a new HBA.
3. Connect the SAS data cable to the tape drive, as illustrated below. Connect a spare power cable from the server's internal power supply to the power connector on the SAS data cable. Figure 8 Connecting cables to the DAT 320 tape drive . Figure 9 Connecting cables to the DAT 160 tape drive . 1. SAS connector to tape drive 4. 2. Power connector Now go to “Secure the drive” on page 36.
If the internal port on the host SAS controller has a mini-SAS connector, use the supplied cable. This is a split cable, but the second branch is not required. Do NOT remove the tie wrap and cover on the spare connector. If the internal port on the host SAS controller has an Infiniband-style connector, you must purchase a separate cable. Always refer to http://www.hp.com/go/connect BEFORE installing your tape drive to check that this configuration is supported and which cable you require. 1.
2. Connect the SAS data cable to the tape drive, as illustrated below. Connect a spare power cable from the server's internal power supply to the power connector on the SAS data cable. Figure 11 Connecting cables to the DAT 320 tape drive . Figure 12 Connecting cables to the DAT 160 tape drive . 1. SAS connector to tape drive 2. Power connector 3. This will leave unused SAS cabling within the server because the other SAS connector is not required in this configuration.
IMPORTANT: This installation uses the HP SAS split cable to replace the existing SAS cable from the host SAS controller to the server's SAS hard disk drive bays. It diverts the wiring from one of the hard disk drive bays to the tape drive. You should be aware that you may lose the use of a hard disk drive bay with this cabling solution. CAUTION: This option normally disconnects the data path to the highest-numbered disk bay, but it is not always possible to identify which disk this is.

4 Installing an external SAS tape drive Please refer to “Installing an internal DAT tape drive” on page 21, if you are installing an internal DAT tape drive. In this chapter: • “Before you start” on page 37 • “Connecting the tape drive to an external SAS port” on page 38 The illustrations in this chapter show the HP StorageWorks DAT 320 tape drive. The process is the same for all models of tape drive. Before you start This installation connects the tape drive directly to the external port.
WARNING! The supplied power cord is HP approved for your specific geographic region. Use of a non-HP approved power cord may result in: 1) not meeting individual country specific safety requirements; 2) insufficient conductor ampacity that could result in overheating with potential personal injury and/or property damage; and 3) an unapproved power cord could fracture resulting in the internal contacts being exposed, which potentially could subject the user to a shock hazard.
3. Connect the SAS cable to the tape drive. Attach the supplied power cord to the tape drive and the mains power outlet. 1. SAS connector 3. Power on/off button 2.

Insert a compatible cartridge into the slot on the front panel. As the cartridge is inserted, the drive takes it and performs a load sequence. NOTE: The illustration shows an 8 mm cartridge.
1. Press the Eject button on the front panel. 1. eject button Figure 26 Ejecting a DAT 320 cartridge from an HP StorageWorks DAT 320 external drive . 2. The drive completes any task it is currently performing, winds the tape to the beginning, and ejects the cartridge. The sequence will take about 25 seconds for a write-enabled cartridge and 10 seconds for a write-protected cartridge.
7 Use the correct media For best performance we recommend HP branded media. Order online at: http://www.hp.com/go/ storagemedia.
Tape drive/media compatibility For optimum performance and storage capacity, use tape cartridges that match your drive's format, and normally use only one cartridge per day. Ideally, use: • HP's DAT 320 cartridges with DAT 320 tape drives • HP's DAT 160 cartridges with DAT 160 tape drives The compatibility between drive models and cartridges is summarized in Table 8 on page 50. Capacities assume a compression ration of 2:1.
When should I use encryption? Your company policy will determine when you need to use encryption. For example, it may be mandatory for company confidential and financial data, but not for personal data. Company policy will also define how encryption keys should be generated and managed. Backup applications that support encryption will generate a key for you or allow you to enter a key manually.
Does encryption affect tape drive performance? Hardware encryption can be used with or without compression and without speed or capacity penalties. Does the tape drive encrypt media in an earlier DAT format? No. Encryption is supported only on DAT 320 GB media. DAT 320 GB TB tapes encrypted on DAT 320 tape drives can be read on any compatible DAT 320 tape drive that supports hardware encryption.
1. tab closed, cartridge write-enabled 2. tab open, cartridge write-protected Figure 27 Write protecting a cartridge . Cleaning cartridges You must use the correct type of cleaning cartridge for your tape drive, see Table 9 on page 53. DAT 320 tape drives: Only clean the tape drive when the Clean LED is flashing. All other models: HP recommends weekly cleaning of the tape drive using an HP cleaning cartridge.
Tape drive model Cleaning cartridge required All other HP StorageWorks DAT tape drives You must use a standard 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.
• Do not verify (DDS does read-after-write checking automatically). • Do not overload the server during backups. Maximize the transfer rate (run overnight with no other processes) and use incremental backups if convenient. • Do not overuse your tape drive—it is designed for approximately three hours of tape pulling per day, not constant usage—and clean the drive regularly. See “Cleaning cartridges” on page 53. • If you want to bulk erase cartridges, this should be done in a controlled environment.
Use the correct media
8 Using HP OBDR In • • • • • this chapter: “Compatibility” on page 57 “What does HP OBDR do?” on page 57 “Remote disaster recovery (ProLiant servers only)” on page 58 “Testing for compatibility” on page 58 “Running HP OBDR” on page 58 Compatibility HP One-Button Disaster Recovery is a standard feature on all HP StorageWorks DAT tape drives. However, it can only be used with specific configurations and will only recover the server to which the tape drive is directly connected.
Remote disaster recovery (ProLiant servers only) The HP Remote Insight Lights-Out Edition (RILOE) on ProLiant servers gives the IT Administrator the ability to completely recover a failed server at a remote location without physically traveling to where the server resides. The on-site non-technical person need only insert the bootable cartridge into the tape drive when asked to do so by the administrator. Refer to the HP OBDR web site at http://www.hp.
2. Hold down the eject button on the tape drive and keep it pressed down while power cycling the tape drive. This activates the HP One-Button Disaster Recovery process. Release the button as soon as the LEDs flash in OBDR sequence, which is: The Ready light shows a repeated pattern of flashing-steady on-flashing. Figure 29 Keeping eject button pressed down, power on in OBDR model . Keyboard shortcut for HP ProLiant servers There is no need to press the Eject button.

A Connecting an external tape drive to an internal SAS port In • • • • this chapter: “Before you start” on page 71 “Remove server cover ” on page 72 “Connect SAS cable to internal SAS port” on page 72 “Reboot the server” on page 79 Before you start For instructions on connecting the SAS tape drive to an external SAS port, see “Installing an external DAT SAS tape drive” on page 37.
PCI slots The HP SAS cable for internal connection is threaded through the rear panel of the server and requires a spare PCI slot to accommodate the cable bracket and SAS connector to the tape drive. Refer to http://www.hp.com/go/connect for the latest information about HBAs and cables. Remove server cover IMPORTANT: These instructions apply ONLY to HP ProLiant servers with SAS controllers or HBAs that do not have an external SAS port. Do not remove the server cover if your server has an external SAS port.
NOTE: These instructions are also valid IF you have installed a new HBA and it has ONLY internal SAS connectors. Install the new HBA and its driver before you start the SAS cabling. 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. Similarly, touch a bare metal part of the drive before installing it. 1.
