2 Drivers and backup software In this chapter: • “Install drivers ” on page 19 • “Upgrade backup software” on page 20 Install drivers Installing on Windows Two drivers are required in order to use HP StorageWorks DAT USB tape drives. • HPDAT: This 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.
4. Once you have installed the tape drive and rebooted, as described in this guide, the tape drive will be detected automatically and the correct driver will be used. Alternative install process, after connecting the tape drive If you have not already installed drivers, the Windows Found New Hardware wizard may run when you power on the server and tape drive. Either: Follow the on-screen instructions to search for the required drivers on the CD-ROM. Or: 1.
NOTE: Certain backup applications require you to use their own Tape driver instead of the HP Tape driver. Enabling encryption (DAT 320 only) Your HP StorageWorks DAT 320 tape drive includes hardware capable of performing data encryption while writing and data decryption while reading, both at full speed. This is only possible with DAT 320 GB media. See also “DAT 320 tape drives and encryption” on page 46.

4. Remove the filler panel from a spare 5¼-inch bay of your server, as described in your server's documentation. With some servers you may also need to remove the half-height device divider. Keep any screws for use in “Secure the drive” on page 30. 5. You are now ready to install your tape drive. Attach mounting hardware If your server requires special rails or other hardware to install the tape drive, mount them on the tape drive now.
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. Slide the tape drive into the open bay, aligning the tray or rails with the slots in the bay, as shown in Figure 6 on page 25. Figure 6 Installing tape drive .
Three USB cables are provided with the tape drive to support connection to three types of internal USB port: • A USB cable with a 4–pin Intel connector (blue) • A USB cable with a 4–pin ProLiant connector (red) • A standard USB cable NOTE: If your server does not have an internal USB port, you must purchase and install a separate USB HBA with an internal port before you install the tape drive. See http://www.hp.com/go/connect for recommended products.
2. Use the cable supplied with the tape drive to connect to the server. • If your server has a standard USB port, use a standard USB cable. You can use the supplied standard USB cable and cable ties to tidy excess cable length. Figure 8 Connecting to a standard USB port . • If your server has a 4-pin USB port, select the 4-pin cable that is appropriate for the pin layout on the USB port.

5 Verify installation Once you have installed the drive hardware, check that drivers have been installed correctly and you have the correct version of backup software, and verify that the tape drive is functioning properly before you store your valuable data. NOTE: Certain backup applications require you to use their own Tape driver instead of the HP Tape driver. 1. Switch on the drive and the server. 2. The tape drive will run its hardware self-test, which takes about 5 seconds.
4. 36 You are now ready to carry out a backup and restore test to check that the drive can write data to tape. Use a blank cartridge. Windows Backup or Linux native backup applications can be used to check basic tape drive operation, but they will not support all the advanced features of your tape drive. We recommend that you upgrade your software application before running this test. Check http://www.hp.com/go/connect for software compatibility and install any recommended upgrades.
6 Operating your tape drive In • • • • • • • this chapter: “Front panel, DAT 320 tape drives” on page 37 “Front panel, DAT 160 tape drives” on page 38 “LED sequences, DAT 320 and DAT 160 tape drives” on page 38 “Front panel, DAT 72 and DAT 40 tape drives” on page 41 “LED sequences, DAT 72 and DAT 40 tape drives” on page 41 “Loading and unloading” on page 42 “Removing power from the drive” on page 44 Front panel, DAT 320 tape drives 1. cartridge slot 5. drive LED 2.

The meaning of different patterns of LEDs is as follows: Tape LED Clean LED Meaning on off The cartridge is loaded and the drive is ready.
Tape LED Clean LED Meaning This is the Media Caution Signal. off or flashing flashing slowly 1. Wait for the current operation to finish, then insert a different tape and repeat the operation that was being performed. 2. If the media caution signal does not show this time, it indicates that the original cartridge was nearing the end of its useful life. Copy any data you want to keep from the original tape onto a new tape if possible, then discard the old tape. 3.
1. 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. These cartridges are thicker than earlier-format DDS cartridges and can only be used with HP StorageWorks DAT 320 and DAT 160 tape drives. See “Data cartridges” on page 45 for more information about tape drive and cartridge compatibility. 2.
Removing power from the drive To ensure reliable operation, do not remove power from the drive during read, write, fast-search, load and unload activities.
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 HP's HP's HP's DAT 320 cartridges with DAT 320 tape drives DAT 160 cartridges with DAT 160 tape drives DAT 72 cartridges with DAT 72 tape drives DDS-4 cartridges with DAT 40 tape drives The compatibility between drive models and cartridges is summarized in Table 5 on page 46.
To make use of this feature you need: • A backup application that supports hardware encryption • DAT 320 GB media; no hardware encryption will be performed when writing earlier generations of tape 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.
WARNING! You should keep a record or backup of your encryption keys and store them in a secure place separate from the computer running the backup software. Not even data recovery services will be able to recover encrypted data without the key! 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.
1. tab closed, cartridge write-enabled 2. tab open, cartridge write-protected Figure 21 Write protecting a cartridge . Cleaning cartridges You must use the correct type of cleaning cartridge for your tape drive, see Table 6 on page 49. 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.
Getting the most out of cartridges and drives • Use mostly the matching media type (DAT 320 media for HP StorageWorks DAT 320, DAT 160 media for HP StorageWorks DAT 160, DAT 72 media for HP StorageWorks DAT 72, DDS-4 media for HP StorageWorks DAT 40). • Use media for the recommended number of times (DAT 320, DAT 160, DAT 72 and DDS-4=100 full backups). Overuse of the tape will cause it to degrade and possibly shed tape debris in the drive.
Use the correct media
8 Using HP OBDR In • • • • • this chapter: “Compatibility” on page 53 “What does HP OBDR do?” on page 53 “Remote disaster recovery (ProLiant servers only)” on page 54 “Testing for compatibility” on page 54 “Running HP OBDR” on page 54 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: HP StorageWorks DAT 320 and DAT 160 tape drives: The Ready light shows a repeated pattern of flashing-steady on-flashing. HP StorageWorks DAT 72 and DAT 40 tape drives: The Tape light and the Clean light on the front panel flash alternately.

10 Troubleshooting In • • • • this chapter: “General Procedure” on page 61 “Verifying USB installation for optimum performance” on page 63 “Frequently asked questions about USB drivers” on page 64 “Problems with cartridges” on page 65 Many users can use HP Library & Tape Tools to help them diagnose problems, see “Diagnostic tools” on page 57. We also recommend the detailed troubleshooting guide at http:// www.hp.com/go/support for comprehensive troubleshooting information.
3. Use the correct media type, for example: • • • • DAT 320 media with DAT 320 drives. DAT 160 media with DAT 160 drives. DAT 72 media with DAT 72 drives. DDS-4 media with DAT 40 drives. NOTE: When using the NT backup application with HP StorageWorks DAT 160 or DAT 320 tape drives, the user must choose 4 mm even when using 8 mm tape cartridges.
Verifying USB installation for optimum performance To confirm that an HP StorageWorks USB DAT drive is installed correctly: • Check that a USB 2.0 port is being used • Ensure that the tape drive is the only device on a USB hub • For DAT models prior to DAT 320 ensure that the HPUSBMSC.SYS driver is being used (DAT 320 tape drives use the Microsoft usbstor driver) Check for USB 2.0 port (Windows) It is important to ensure that you connect your drive to a USB 2.0 port. The drive will work on a USB 1.
2. Right click on the My Computer icon on the desktop, then click Manage. 3. Click Device Manager from the right hand pane of the management console. 4. Select Devices by connection from the View menu. 5. Navigate through the hardware tree in the right hand pane to locate the tape device. 6. Immediately above the device in the tree will be the USB Mass Storage layer driver, this should display HP USB Mass Storage Device.
• DAT 320 models: No. • All other models: Run the driver installer from the StorageWorks CD in order to install the HPUSBMSC.SYS driver. How can I check that my drive is installed correctly? See “Verifying USB installation for optimum performance” on page 63. Problems with cartridges If you experience any problems using HP branded cartridges, check: • The cartridge case is intact and that it contains no splits, cracks or damage. • The cartridge has been stored at the correct temperature and humidity.
2. Check that you are using the correct media for the tape drive, see “Use the correct media” on page 45. 3. Make sure that you have loaded the cartridge with the correct orientation (see “Loading and unloading” on page 42). 4. Check for damage to your media and discard it if it is damaged. 5. Use a new or known-good piece of media and see if it loads. If it does, the original cartridge is faulty and should be discarded. 6. Check if another DAT drive of the same model will accept the cartridge.
11 Replacing an internal tape drive If your tape drive proves to be faulty and cannot be repaired and it is still covered by the original warranty, it will be replaced. HP will provide a replacement tape drive free of charge. Based on availability and where geography permits, the replacement tape drive will be shipped for next business day delivery. Same day or four-hour delivery may be offered at an additional charge where geography permits.

A USB configuration guide In • • • • this chapter: “USB in HP StorageWorks DAT devices” on page 69 “USB terminology” on page 69 “Setting up a USB network” on page 70 “USB cables” on page 70 USB in HP StorageWorks DAT devices The HP StorageWorks DAT tape drive is a USB 2.0 logo certified device. It supports the high-speed USB transfer rate with a theoretical maximum transfer of over 50 MB/s. (The actual backup rate will be less.
The host will give network bandwidth priority to periodic devices and will share any remaining bandwidth equally among any active bulk transfer devices. USB supports many types of devices and three data transfer rates, low speed, full speed, and high speed. (A keyboard does not need to transfer data to the system at the same speed as a cable modem.) The transfer speed capabilities of a device are often referred to by the USB specification revision in which the transfer rate was defined. Therefore a USB 2.
