Ultrium full-height SCSI Tape Drives

• Youwillneedaproperlyinstalledandconﬁgured 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?.

• ForoptimumperformancethedriveshouldbetheonlydeviceontheSCSIbus.

• 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 h 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 a rray 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 b urst transfer rate of 320 MB/sec. HP Ultrium 460 drives suppor t 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 busofasimilarorhigherspeciﬁcation. This means that you need:

• An Ultra320 bu s 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 d ata 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.

How c an 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 C D -ROM or h current SCSI conﬁguration (see also Diagnostic tools ). This will provide information about the SCSI bus and the SCSI IDs in use.

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.

2Driversandbackupsoftware

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 StorageW orks CD-ROM to install the drivers BEFORE you connect the tape drive.

Updates to the drivers may be provided from time to tim e on the HP support web site (h

ttp://www.hp.com/support). We recommend that these are installed after using the installer on the

CD-ROM.

Installing on UNIX

The recomm upgrade d device ﬁ l

ended backup applications use the operating system’s standard, built-in device drivers. To

rivers we recommend that you patch to the latest version of the operating system or conﬁgure

es, as described in the UNIX Conﬁguration Guide on the CD-ROM.

Installing on IA64

If you are installing a removable Ultrium tape drive, please refer to Installing a removable Ultrium tape

drive.

Check the driv e’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 un not use SCSI ID 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.

ique SCSI ID number. The drive can be assigned any unused ID between 0 and 15. Do 7, which is reserved for the SCSI controller. SCSI ID 0 is typically assigned to the boot

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

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 C D-ROM also contains instructions on how to determine the SCSI IDs of existing devices on UNIX servers.

2. Changethetapedrive’sSCSIID,ifnecessary.

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 fo

ttp://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.

WARN ING!

To avoid pe from the m

r a number of industry-standard servers may be available. For more details refer to:

rsonal injury or damage to the server or tape drive, ensure that the server is disconnected

ains 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:

• P hillips 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 p ower cables from other devices to ma neuver 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 m

/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 h ave the appropriate blanking plates installed so that airﬂow is maintained.
