Which operating systems are supported?

HP StorageWorks Ultrium drives can be connected to servers running under Windows®, NetWare, HP-UX, UNIX, Tru64, Linux and other major operating systems. Refer to the “HP StorageWorks Tape Software Compatibility” topic on our World Wide Web site (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:

•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. This should be an Ultra320 or Ultra160 SCSI HBA. See also ”Why is the SCSI bus type important?” on page 11.

•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 tape drives are auto terminating, as long as they are on a dedicated SCSI bus or the last device on a chain.

10 Before you start

•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 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, half-height drive bay in your server (or 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” on page 17.

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” on page 27.

Check the usage models on ”Usage models” on page 13. 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” on page 31.

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 920 drives support a burst transfer rate of 320 MB/sec. HP Ultrium 448 and 232 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 920 drives

An Ultra160 or Ultra320 SCSI bus for HP Ultrium 448 and 232 drives

If you attach the drive to a lower specification SCSI bus, it will still work but data may 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.

HP StorageWorks Ultrium SCSI Tape Drives User Guide 11

Table 1 Supported SCSI bus types

Ultra320 LVD	Yes. This is a recommended configuration for Ultrium 920, Ultrium 448 and

Differential

How can I check the SCSI bus type and SCSI ID?

For many operating systems, you can install and run HP Library & Tape Tools from either the

HP StorageWorks Tape CD-ROM or www.hp.com/support/tapetools to check your server’s current SCSI configuration (see also ”Diagnostic tools” on page 53). This will provide information about the SCSI bus and the SCSI IDs in use.

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, an installation check, and performance information and tools

•Learn about your product

•Register your product

•Buy media online

•Troubleshoot with HP Library & Tape Tools.

12 Before you start

Usage models

HP StorageWorks Ultrium tape drives can be used in a stand-alone or network environment. However, they should always be directly attached to suitably-rated SCSI connector on the storage server.

		may limit performance
Ultrium 232	Recommended	Recommended, anything less than 100 Base-T Ethernet
		may limit performance

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 920 at any compression ratio. To maximize the capability of your Ultrium 920 drive, utilize aggregated disk sources (RAID) with multiple disk spindles.

A single disk, particularly a fast disk such as a 15K RPM drive, will be sufficient for Ultrium 448 and Ultrium 232 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” on page 54.

Use our free performance assessment tools, which are available stand-alone 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 stand-alone 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 www.hp.com/go/connect for the latest supported configurations.

2 Drivers and backup software

Install drivers

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. It is regularly updated and is available on the HP StorageWorks CD-ROM or on the HP Support web site at www.hp.com/support.

NOTE: The HP 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 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 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 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: www.hp.com/go/connect and select tape backup.

2.Select software compatibility.

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 49.)

4.Make sure you have a backup application that supports HP StorageWorks Ultrium tape drives and download any upgrades or patches, if required.

3 Installing an internal Ultrium tape drive

If you are installing an external Ultrium tape drive, please refer to Chapter 4. If you are installing a removable Ultrium tape drive, please refer to Chapter 5.

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

HP StorageWorks Ultrium SCSI Tape Drives User Guide 17

1.Determine whether you need to change the SCSI ID from the default of 3.

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

page 53). 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. (See also ”Troubleshooting with Library & Tape Tools” on page 53.)

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: 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.

18 Installing an internal Ultrium tape drive

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 40o C ambient operation. This reduces to 4 cfm at 35o C ambient operation. Ensure that empty bays have the appropriate blanking plates installed so that airflow is maintained.

4.Remove the filler panel from a spare 5¼-inch bay of your server, as described in your server’s documentation. With some servers, such as the HP AlphaServer ES40, you must also remove the half-height device divider.

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.

If your server does not require special mounting hardware, proceed to ”Install drive” on page 22 now.

HP StorageWorks Ultrium SCSI Tape Drives User Guide 19

CAUTION: The Ultrium half-height drive only allows 3 mm of the engagement of the screw into the drive. If you remove an existing drive, do not assume the screws that you remove are the correct length for your new Ultrium drive. Always use the screws supplied with your Ultrium drive.

HP ProLiant servers

NOTE: If mounting hardware is supplied with your tape drive, it may not be exactly the same as shown in the illustrations.

Different models of server require different mounting methods. The server may also incorporate a locking mechanism to hold the tape drive in place. See ”Secure the drive” on page 25.

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.

Mounting rails

Some HP ProLiant servers, such as ML570, require mounting rails. These may be metal or plastic rails attached to the server's drive bay filler panel.

Use a regular Phillips screwdriver to attach the appropriate rails. Use the M3 screws provided with the tape drive, in the screw pack labeled General Mounting Screws’, as shown in Figure 5a.

Figure 5 Attaching mounting rails in a typical HP ProLiant ML570

Ensure you do use the M3 screws provided. The rails may be attached to the filler panel by screws of a different thread/size type and these should not be used. If in doubt, refer to your HP ProLiant server documentation.

Mounting screws

Other HP ProLiant server models, such as ML350 and ML370, only require the use of special locating screws with no mounting rail.

Use a T8 Torx screwdriver to attach the appropriate screws. You may need to purchase the M3 screws separately. Position the screws, as shown in Figure 6.

Figure 6 Attaching locating screws in a typical HP ProLiant 350 or 370

•HP ProLiant ML350: Use the metal shims and screw pack labeled ‘ProLiant 350’. These have a thicker head than the general mounting screws.

•HP ProLiant ML370: Use the metal shims and screw pack labeled ‘ProLiant 370’. These have a thick offset piece and a thicker head than the general mounting screws.

Other servers

1.Attach the appropriate mounting hardware. Refer to the manufacturer’s documentation for instructions.

•If you are installing on a server that requires a tray, place the tape drive in the tray.

•Some servers have snap-on mounting rails attached to the filler panel. These can be removed and attached to the tape drive with screws.

HP StorageWorks Ultrium SCSI Tape Drives User Guide 21

Install drive

1.Slide the tape drive into the open bay, aligning the tray or rails with the slots in the bay, as shown in Figure 7.

Figure 7 Installing tape drive

If your server does not use mounting hardware, check that the holes in the chassis are aligned with the holes in the side of the tape drive.

Do not secure the drive at this point because you may have to move the drive to get the cables into place.
