Which operating systems are supported?
HP StorageWorks Ultrium drives can be connected to servers running under Windows®, Linux and other major operating systems. Refer to the “Software Compatibility” section on our “HP StorageWorks Tape Compatibility” web site (http://www.hp.com/go/connect/) for the most recent information about the operating system versions that are supported.
How do I connect the drive to my server?
The following guidelines apply:
Ultrium full-height SCSI Tape Drives |
13 |
•You will need a properly installed and configured SCSI host bus adapter (HBA) or a built-in SCSI controller on your server and a suitably-rated SCSI cable. See also Why is the SCSI bus type important?.
•For optimum performance the drive should be the only device on the SCSI bus.
•Always terminate the SCSI bus. Ultrium internal and removable tape drives require terminators; external drives are auto terminating, as long as they are on a dedicated SCSI bus or the last device on a chain.
•Do not attach the drive to the same SCSI bus as your disk drive or to a RAID controller (unless you are connecting to a ProLiant server with a Smart Array 6i RAID controller).
NOTE:
Always refer to http://www.hp.com/go/connect/ to ensure that you are connecting to a supported HBA running the recommended firmware version.
Internal drives
The tape drive is installed into a spare, industry-standard, 5¼-inch, full-height drive bay in your server (or into an HP Rack-Mount Option Kit) and is attached to the SCSI bus of the host server. Use an LVDS-compatible ribbon cable to connect the tape drive to a spare 68-pin, high density (HD), wide SCSI connector on the host server. For most servers we recommend that you use the terminated SCSI ribbon cable supplied with the drive.
See also Installing an internal Ultrium tape drive.
External drives
Your tape drive is supplied with a 68-pin, wide, VHD-to-HD SCSI cable to attach to the host server. See also Installing an external Ultrium tape drive.
Check the usage models on Usage models. This shows how the HP StorageWorks Ultrium tape drive can be used in different system architectures.
Removable drives
The individual tape drives are connected to their host server via the high-density LVD/SE SCSI connectors on the back of the tape array. They do not require any SCSI cables to plug into the tape array. However, cabling and terminators are required to connect the tape array with the SCSI host. See also Installing a removable Ultrium tape drive.
Why is the SCSI bus type important?
The SCSI bus type determines the speed at which data can be transferred between devices on the bus and the maximum length of cable that can be used. HP Ultrium 1840 and 960 drives support a burst transfer rate of 320 MB/sec. HP Ultrium 460 drives support a burst transfer rate of 160 MB/sec. To benefit from this level of performance, it is important to ensure that the drives are connected to a SCSI bus of a similar or higher specification. This means that you need:
•An Ultra320 bus for HP Ultrium 1840 and 960 drives. An Ultra160 or Ultra320 SCSI bus for HP ultrium 460 drives. If you attach the drive to a lower specification SCSI bus, it may still work but data will not be transferred as quickly.
•LVD-rated SCSI cabling and terminators. The LVD interface enables the data to be transferred at the drive’s maximum rate.

A RAID disk subsystem is recommended for all usage models.
A single spindle disk will not be able to deliver good data throughput for an Ultrium 1840 or Ultrium 960 tape drive at any compression ratio. To maximize the capability of your Ultrium 1840 or 960 tape drive, utilize aggregated disk sources (RAID) with multiple disk spindles.
A single spindle disk, particularly a fast disk such as a 15K RPM drive, will be sufficient for Ultrium 460 tape drives, but be aware of other factors that can affect performance—such as, compressibility of data, disk fragmentation and the number of files. See also Optimizing performance.
You can use our free performance assessment tools, which are available standalone or integrated into HP Library & Tape Tools, to check tape performance and test whether your disk subsystem can supply data at the optimum transfer rate. You can also use these tools to calibrate your restore performance and maximal tape performance with more compressible data.
Other usage models
The tape drive may work with other usage models, such as network attach storage (NAS) and storage area networks (SAN), but HP does not currently provide technical support for installing and using standalone Ultrium tape drives with these architectures. Similarly, connection to fibre channel may be possible, if you purchase and install a fibre channel/SCSI bridge, but it is not currently a supported option. Please check http://www.hp.com/go/connect for the latest supported configurations.
Using the HP StorageWorks Tape CD-ROM
The HP StorageWorks Tape CD-ROM is a central source of information about your tape drive with utilities for getting the best performance from your tape drive.
Use the HP StorageWorks Tape CD-ROM to check installation, as described in this guide, and to verify and troubleshoot performance after installation. It helps you to:
•Install your product, which includes access to drivers, and performance information and tools
•Learn about your product
•Register your product
•Buy media online
•Troubleshoot with HP Library & Tape Tools.

2 Drivers and backup software
Install drivers
NOTE:
The HP Tape driver is suitable for use in most applications, but refer also to the documentation of your software application to ensure you are using the recommended driver.
Installing on Windows
The driver available from Microsoft update is acceptable, but the HP driver provides better support for all the features of your new tape drive.
The CD-ROM contains a driver install package for the following Microsoft Windows operating systems: Windows Server 2000, Windows Server 2003 and Windows XP. If you prefer to use Windows Device Manager to install the tape drivers manually, you will find them in the drivers directory on the CD-ROM.
NOTE:
We recommend that you use the installer package on the HP StorageWorks CD-ROM to install the drivers BEFORE you connect the tape drive.
Updates to the drivers may be provided from time to time on the HP support web site (http://www.hp.com/support). We recommend that these are installed after using the installer on the CD-ROM.
Installing on UNIX
The recommended backup applications use the operating system’s standard, built-in device drivers. To upgrade drivers we recommend that you patch to the latest version of the operating system or configure device files, as described in the UNIX Configuration Guide on the CD-ROM.
Installing on IA64
If you are installing on an IA64 system, such as an HP Integrity server, check http://www.hp.com/go/ connect for the latest information on the availability of backup application upgrades and drivers.
Upgrade backup software
It is important to check http://www.hp.com/go/connect for software compatibility and install any recommended upgrades.
For optimum performance it is important to use a backup application that is appropriate for your system’s configuration. In a direct attach configuration, where the tape drive 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. HP, Symantec, Legato, Yosemite and Computer Associates all provide suitable products. Further details about these and other products that may be appropriate can be found on our connectivity web site.
1.Go to our connectivity web site: http://www.hp.com/go/connect and select tape backup.
2.Select software compatibility.
Ultrium full-height SCSI Tape Drives |
19 |
3.Select your combination of operating system and tape drive model in the table. A list of supported backup applications is displayed. This will also tell you whether your configuration is compatible with HP One-Button Disaster Recovery, HP OBDR. (All HP StorageWorks Ultrium tape drives support HP OBDR. However, you can only use this feature if your system configuration and backup application also support it. See "Compatibility" on page 53.)
4.Make sure you have a backup application that supports HP StorageWorks Ultrium tape drives and download any upgrades or patches, if required.
Enabling encryption
Your HP Ultrium 1840 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 LTO-4 media. See also refer to "Encryption" on page.
If you wish to make use of the encryption capability, you must enable this feature via the backup software application. Refer to http://www.hp.com/go/connect to find out which applications support this advanced data protection capability.

3 Installing an internal tape drive
If you are installing an external Ultrium tape drive, please refer to Installing an external Ultrium tape drive.
If you are installing a removable Ultrium tape drive, please refer to Installing a removable Ultrium tape drive.
Check the drive’s SCSI ID
Your HP StorageWorks Ultrium drive is shipped with a default SCSI ID of 3. Each device on the SCSI bus must have an unique SCSI ID number. The drive 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 tape drive is on a dedicated SCSI bus.
CAUTION:
Static electricity can damage electronic components. Always wear an antistatic wriststrap if possible. If not, to equalize the electromagnetic charges, touch a bare metal part of the server (such as the back plate) before you remove the tape drive from its bag.
Figure 3 Checking the SCSI ID
1. Determine whether you need to change the SCSI ID from the default of 3.
Ultrium full-height SCSI Tape Drives |
21 |
For most operating systems you can run HP Library & Tape Tools from the HP StorageWorks Tape CD-ROM to check your server’s current SCSI configuration (see Diagnostic tools ). This will provide information about the SCSI bus and the SCSI IDs in use. To do this, select the ‘troubleshoot with L&TT’ option from the CD-ROM menu.
The UNIX Configuration Guide on the HP StorageWorks Tape CD-ROM also contains instructions on how to determine the SCSI IDs of existing devices on UNIX servers.
2.Change the tape drive’s SCSI ID, if necessary.
The SCSI ID is set using jumpers on a set of pins at the rear of the drive, as shown in Figure 3. Use tweezers or small pliers to move the jumpers to the pattern corresponding to the ID you want. Spare jumpers are provided with the drive.
Prepare mounting bay
For many servers, no mounting tray or rails are required. Devices simply slide into the server’s chassis and are fixed with screws. Other servers have built-in trays or rails.
Rail kits for a number of industry-standard servers may be available. For more details refer to: http://www.hp.com/go/connect.
Some servers use non-standard mounting rails and do not include spares. If this is the case with your system, you will have to order these accessories from the server manufacturer before you can install the tape drive.
WARNING!
To avoid personal injury or damage to the server or tape drive, 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. Similarly, touch a bare metal part of the drive before installing it.
1.Assemble the necessary tools and materials:
•Phillips screwdriver
•Flat-bladed screwdriver (if your server uses slotted screws)
•Torx screwdriver (if your server uses torx screws)
•Your server manuals (for reference during installation)
2.Perform a normal system shutdown and turn off the server and any connected peripherals.
3.Remove the cover and front panel from the server, as detailed in your server’s documentation.
As you work inside the server, you may have to disconnect other signal cables or power cables from other devices to maneuver the new drive into place. If you have to do this, make a note of their position and connections so you can put them back correctly later.
NOTE:
The server must provide forced cooling and be capable of drawing 6 cfm (0.17 m3/minute or 10.08 m3/hour) of air through the tape drive at up to 35 C ambient operation. This rises to 8 cfm for up to 40 C ambient operation. Ensure that empty bays have the appropriate blanking plates installed so that airflow is maintained.
