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.

ttp://www.hp.com/go/connect/ to ensure that you are connecting to a supported

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.

Usage models

HP StorageWorks Ultrium tape drives can be used in a standalone or network environment. However, they should

always be directly attached to suitably-rated SCSI connector on the storage server.

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.

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.

Where should the SCSI terminator be?

Termination must be present at two and ONLY two positions on the SCSI bus—at the beginning of the SCSI bus and at the end of the SCSI bus. Termination is normally enabled by default on the HBA and most internal SCSI cables have a terminator attached. This will usually be a small, rectangular block of plastic attached to the cable end and ma rked ‘SCSI Terminator’.

Therefore, assuming the HBA is the ﬁrst device on the bus, you should check that the second terminator is placed after the last device, as shown in Figure 8, item 1.

Check the driv e’s SCSI ID

Your HP Stora must have an unique SCSI ID number. The drive can be assigned any unused ID bet ween 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.

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

For many operating systems you can install and run HP Library & Tape Tools from the HP StorageWorks Tape CD-ROM to check your server’s current SCSI conﬁguration. 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.

Connect the SCSI cable

A 68-pin, wide VHD-to-HD SCSI cable is provided to connect your HP StorageWorks Ultrium tape drive to a VHD SCSI port on an LVD SCSI bus. If your server has an HD SCSI port, you must either purchase and install a VHD-to-HD adapter or use a n HD-to-HD cable instead of the supplied cab le. Refer to our web site for recommended products: h

CAUTION:

To avoid damaging the computer or tape drive, ensure that both are powered off while you attach the SCSI cable.

1. Make sure you are connecting to a recommended SCSI bus type. For optimum performance your

tape drive should only be connected to a SCSI bus that can transfer data at a rate that supports the tape drive’s maximum burst transfer speed. HP Ultrium 1840 and 960 tape drives should be connected to an Ultra320 SCSI bus. See alsoWhyistheSCSIbustypeimportant?.Donot connect the tape drive to a single-ended SCSI bus or to RAID controller. For optimum performance, we recommend that your HP StorageWorks Ultrium drive is installed on a dedicated SCSI bus. If it is not, do not connect it to the same bus as your disk drive.

2. Perform a normal system shutdown and turn off the server and any connected peripherals.

How do I connect the drive to my server?

The following guidelines apply:

• ForoptimumperformancethedriveshouldbetheonlydeviceontheSCSIbus.

• If you daisy-chain devices, make sure that devices are of the same SCSI type and that each device

on the same SCSI bus has a unique SCSI ID and is terminated appropriately. Do not daisy-chain more than two devices on the same SCSI bus.

Ultrium full-height SCSI Tape Drives

• If you daisy-chain devices, make sure that devices are of the same SCSI type and that each device

on the same SCSI bus has a unique SCSI ID and is terminated appropriately. Do not daisy-chain more than t wo devices on the same SCSI bus.

• Always terminate the SCS I bus.

• Do not attach the drive to the same SCSI bus as a your disk drive or to a RAID controller unless

you are connecting to a ProLiant server with a Smart Array 6i RAID controller.

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, suitably-rated cabling and terminators are required to connect the tap e array with the SCSI host.

CAUTION:

When handling a tape drive, hold the drive by the side carrier framework. To avoid possible damage, do not hold the body of the drive and do not push or pull on the tape drive’s front panel.

2. Slide the tape drive into one of the open bays, ensuring that the guide rails on both sides of the drive

locate into the slots on the partition wall. Carefully but ﬁrmly ensure the tape drive is pushed fully in so that the rear connectors are securely seated. The extractor level will close slightly.

Termina signal r

There mu

tors are essential, as they provide the correct voltages on the SCSI bus and prevent unwanted

eﬂections from interfering with data transfers. The rule is:

st be termination at both physical ends of the bus and only at the ends.

Normally the HBA forms one end of the SCSI bus and provides termination. You, therefore, need to ensure that the other end of the bus is terminated. Attach the terminator to the app ropriate SCSI-OUT connect

or on the tape array.

Replacing the drive

HP StorageWorks Ultrium removable drives can be removed and replaced without powering down the tape array. However you should be aware of the following:

• If all drives in the tape array are powered up when the system is turned on, the host will be aware

ofthosedrives. Youcanremoveanyofthosedrivesandreplaceitwithanotherdriveaslong as there is no activity on the bus.

• Do not remove or add drives to a bus that already has drives connected and running, for example

backing up or restoring data. Wait until there is no activity on the bus before removing or adding drives.

• Ifadriveisnotpowereduporyouplaceadriveinanemptyslotafter the system has been

powered up, the system will have to be reset before the host will recognize the drive.

• The SCSI IDs are controlled by the tape array, not by the drives themselves, so if you remove a

drive and replace it with another the ID will not change.

1. Pull the extraction lever of the drive that you want to replace so that it is in the out position.

6 Verif y 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.

1. Switch on the drive and the server.

2. The tape drive will run its hardware self-test, which takes about 5 seconds. If self-test passes, the

green Ready LED ﬂashes and then shows steady green. If the test fails, the Drive Error and Tape Error LEDs ﬂash, while the Ready and Clean LEDs are off. This continues until the drive is reset. See “Loading and unloading” on page 47 for more information about front panel lights.

• Ifyouinstalleddriversbeforeconnectingthetapedrive(Windowsonly)

The tape drive should be detected automatically and the correct drivers used. (See “Install drivers ” on page 19.) If the Windows Found New Hardware wizard runs, cancel it - you can use Device Manager to check that the driver is installed.

• Installing drivers after connecting the tape drive (Windows only)

If you have not already installed drivers, the Windows Found New Hardware wizard will run when you power on the server and tape drive. Either follow the on-screen instructions to search for the required driver on the HP StorageWorks CD-ROM o r cancel the wizard and run the install package from the CD-ROM.

• Installing drivers (other operating systems)

Drivers are included with the operating system and should be loade d automatically.

NOTE:

Certain backup applications require you to use their own Tape driver instead of the HP Ultrium Tape driver.

3. Verify that the tape drive installation was successful.

HP StorageWorks Library & Tape Tools (L&TT) is the recommended diagnostic and support tool for yourHPtapedrive. Useittoverifyinstallationandconﬁrm that your tape drive is functioning correctly before you use it for backup. It is available free at h

4. For all operating systems ensure that you have downloaded any upgrades necessary for your

backup application. Check h any recommended upgrades.

5. Carry out a backup and restore test to check that the drive can write data to tape. Use a blank

cartridge.

Windows Backup or Unix native backup applications c an 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.

Cartridges

Cleaning cartridges

The recommended cleaning cartridges is the HP Ultrium universal cleaning cartridge, C7978A (Orange). This cleaning cartridge is designed to work with any Ultrium drive. It may be used for up to 50 cleans.

NOTE:

Do not use the earlier HP Ultrium cartridge, C7979A (Blue), or Ultrium cartridges from other manufacturers.

Data cartridges

HP StorageWorks Ultrium tape drives use Ultrium tape cartridges. These are single-reel cartridges that match your drive’s format and are optimized for high capacity, throughput and reliability. Compatible media can be recognized by the Ultrium log o, which is the same as the logo on the front of your drive. Do not use other format cartridges in your tape drive and do not use Ultrium cartridges in o ther format tape drives.

For optimum performance always use a data cartridge that matches the speciﬁcation of your tape drive, (see Table 9 on page 49). A lower speciﬁcation will have a lower transfer speed and may not support write activities; a higher speciﬁcation will not support read or write. HP recommends:

• Ultrium 1.6 TB RW* and Ultrium 1.6 TB* WORM tape cartridges for use with Ultrium 1840

tape drives.

• Ultrium 800 GB RW* and Ultrium 800 GB* WORM tape cartridges for use with Ultrium 960

tape drives.

• Ultrium 400 GB RW* and Ultrium 400 GB* WORM tape cartridges for use with Ultrium 460

Ultrium 1840 tape drives and encryption

Your Ultrium 1840 tape drive includes hardware capable of performing data encryption at full speed while writing data, and decrypting when reading.

Encryption is the process of changing data into a form that cannot be read until it is deciphered, protecting the data from unauthorized access and use. HP Ultrium 1840 tape drives use the strongest version of the industry-standard AES encrypting algorithm to protect your data. To make use of this feature you need:

• a backup application that s uppor ts hardware encryption

• Ultrium 1.6 TB media (C7974A or C7974W ); no encryption will be performed when writing earlier

mpany conﬁdential and ﬁnancial data, but not for personal data. Company policy will also deﬁne

for co 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.

NOTE:

Encryption with keys that are generated directly from passwords or passphrases may be less secure than

yption using truly random keys. Your application should explain the options and methods that are

encr

lable. Please refer to your application’s user documentation for more information.

How do I enable encryption?

Hardware encryption is turned off by default and is switched on by settings in your backup application, where you also generate and supply the encryption key. Your backup application must support hardware encryption for this feature to work. The software supplied with the tape drive provides this support. See

ttp://www.hp.com/go/connect for an up-to-date list of other suitable backup software.

Use the correct media

When will I be ask

Encryption is primarily designed to protect the media once it is ofﬂine and to prevent it being accessed from another m achine. You will be able to read and append the encrypted media without being prompted for a key as long as it is being accessed by the machine and application that ﬁrst encrypted it.

There are two ma

• If you try to import the media to another machine or another instance of the backup application

• If you are recovering your system after a disaster

ed to enter the key?

in instances when you will need to know the key:

What happens if I don’t remember the key?

If you are unable to supply the key when requested to do so, neither you nor HP Support will be able to access the encrypted data.

This guarantees the security of your data, but also means that you must be careful in the management of the encryption key used to generate the tape.

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.

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 Ultrium format?

No. Encryption is supported only on Ultrium 1.6 TB media (C7974A or C7974W).

Ultrium 1.6 TB tapes encrypted on an HP Ultrium 1840 drive can be read on any compatible Ultrium 1840 tape drive that supports hardware encryption.

HP Ultrium 1 840 tape drives can read Ultrium 800 GB and Ultrium 400 GB media and write Ultrium 800 GB media, but hardware encryption is not supported on these formats.

Where can I get more information?

For more information about AES encryption, encryption keys, and using hardware encryption with your HP Ultrium 1840 tape drive, see the White Papers on h

tapewhitepapers.html.

For detailed instructions about enabling encryption please refer to the documentation supplied with your backup application. This will also highlight any default states, for example when copying tapes, that may need changing if using encrypted tapes.

Troubleshooting with Library & Tape Tools

1. When Library & Tape Tools is ﬁrst run, it will scan for HP tape drives and libraries on your system

and ask you to select the one to work with. At this time you can see the HBA conﬁguration of your server and how your devices are connected.

2. Once you have selected your device you have a number of choices for troubleshooting.

•Deviceidentiﬁcation: shows part number, serial number and information about any cartridge loaded.

• Firmware upgrade: allows you to locate and upgrade to the latest ﬁrmware. You will need to be connected to the internet for this.

• Run tests: allows you to run proactive tests on your drive, such as the drive assessment test, which will verify the functionality of your drive in around 20 minutes. HP recommends running this test before calling HP Support. You will need to provide a ‘trusted’ cartridge that can be written to during this test.

• G enerate a support ticket: this is a full dump of the drive logs along with interpretation and isusedbyHPSupporttolearnabouttheconditionofyourdrive.

Can your system deliver the required performance?

• The Ultrium 1840 tape drive can write uncompressed data at up to 120 MB/s (432 GB/hour)

• TheUltrium460tapedrivecanwriteuncompresseddataatupto30MB/s(108GB/hour)

To obtain this performance it is essential that your whole system can deliver this performance. In most cases, the backup application will provide details of the average time taken at the end of the backup.

Typical areas where bottlenecks can occur are:

• Disk subsystem

AsinglespindlediskwillnotbeabletodelivergooddatathroughputforanUltrium1840or 960 tape drive at any compression ratio. To maximize the capability of these tape drives, utilize aggregated disk sources (RAID) with multiple disk spindles.

Asinglespindlediskmaybesufﬁcient for an Ultrium 460 tape drive, depending on your data’s compressibility. Best practice to ensure good throughput is to utilize multiple disk spindles or data sources.

• System architecture

Be aware of the architecture of your data protection environment; multiple clients backed up over anetworkmaymeanyouareunabletotakeadvantageoftheUltrium1840or960tapedrive because the Ethernet infrastructure connecting such systems may limit performance.

For Ultrium 460 tape drives, the ag gregation of multiple client sources over a network provides a good way of delivering good performance, but anything less than Gigabit Ethernet may limi t performance.

Some enterprise class backup applications can be made to interleave data from multiple sources, such as clients or disks, to keep the tape drive working at optimum performance.

• Tape media type

The data cartridge should match the speciﬁcation of the tape drive. A lower speciﬁcation will have a lowertransferspeed(see“Data cartridges” on page).

Use Ultrium 1.6 TB or Ultrium WORM 1.6 TB cartridges with Ultrium 1840 tape drives, Ultrium 800 GB or Ultrium WORM 800 GB cartridges with Ultrium 960 tape drives, and Ultrium 400 GB or Ultrium WORM 400 GB cartridges with Ultrium 460 tape drives.

• Data and ﬁle types

The type of data being backed up or restored can affect performance. Typically, small ﬁles incur greater overhead in processing and access than large ﬁles. Equally, data that is not compressible

will always limit the speed at which the drive can write/read data. You will achieve no more than native rates with uncompressible data.

Examples of ﬁles that compress well are plain text ﬁ les, spreadsheets; those that compress poorly are those that are either compressed as part of their format (such as, JPEG photographic ﬁles) or stored as compressed (such as, .ZIP ﬁles or .gz/.Z ﬁles on Unix platforms).

Replacing a tape drive

ASCSIconﬁ guration guide

SCSI in HP StorageWorks Ultrium devices

HP StorageWorks Ultrium 1840 and 960 tape drives are high performance Ultra320 SCSI compatible devices; HP StorageWorks Ultrium 460 tape drives are high performance Ultra160 SCSI compatible devices.

They are designed to operate on a low voltage differential (LVD) SCSI interface and are not compatible with high voltage differential (HVD) SCSI devices.

Ultrium 1840 and 960 tape drives support a burst transfer rate of 320 MB/sec; Ultrium 460 tape drives support a burst transfer rate of 160 MB/sec.

To beneﬁt from this level of performance, it is impor tant to ensure that the drives are connected to a SCSI busofasimilarorhigherspeciﬁcation. This means that you need:

• An Ultra320 bus for HP Ultrium 1840 and 960 tape drives. An Ultra160 or Ultra320 bus for

HP Ultrium 460 tape drives.

If you attach the drive to a lower speciﬁcation SCSI bus, it will still work but data may not be transferred as quickly. Ultra2 SCSI is also supported, but performance may be degraded.

• LVD-rated SCSI cabling and terminators. The LVD interface enables the data to be transferred at

the drive’s maximum rate and provides a maximum cable length of 12 meters.

Daisy chai

ning devices

NOTE:

We do not recommend daisy chaining the HP StorageWorks Ultrium 1840 and 960 tape drive with other devices.

If you need to connect multiple devices to the bus, performance may be restricted if there are too many devices on the bus that are accessed simultaneously. Connecting devices of lower SCSI speciﬁcation, such as Ultra2 or Ultra SCSI, may also restrict performance to your tape drive. Using Single Ended 8-Bit SCSI devices on the same bus is not recommended, as performance will be severely impacted and complicated bus con ﬁguration is required to overcome bus termination issues.

Make sure that the last device on the SCSI bus is terminated. HP recommends that you do not attach the tape drive to the same SCSI bus as the disk drive. See SCSI termination for more information about terminating HP StorageWorks Ultrium tape drives.

SCSI terminology

SCSI is a bus interface: all the devices are connected to a single cable (some of this may be inside and some outside the host computer’s case). The connection to the host itself is known as the Host Bus Adapter (HBA). You can have several HBAs in a single computer, each with its own SCSI bus: this is a common arrangement in high-performance servers. Some host bus adapters (such as the LSI Logic LSI22320-R) have more than one SCSI bus available on a single card.

Various terms are used when describing SCSI devices. These terms relate to the factors that affect performance and cable length:

• The speed of the data bus, which may be Fast, Ultra, Ultra2, Ultra3, Ultra160 or Ultra320.

• The width of the data bus, which may be Narrow or Wide (16-Bit or 8-Bit).

Ultrium full-height SCSI Tape Drives

• The voltage level of the interface, which may be single-ended (SE) or low voltage differential (LVD).

Setting up the S

Each device on a ID (identiﬁer)

NOTE:

HP recommends that a dedicated host bus adapter is used for the tape drive. A suitable adapter is available from HP as an accessory (see h

SCSI ID numbers

For wide SCSI buses, the SCSI ID will be a number from 0 through 15, so a typical wide SCSI HBA can accommodate up to ﬁfteen other devices. (On narrow SCSI buses, the SCSI ID is a number from 0 through 7.)

Each device must have a unique SCSI ID. 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 ded icated SCSI bus.

SCSI termination

Terminators are essential, as they provide the correct voltages on the SCSI bus and prevent unwanted signal reﬂections from interfering with data transfers. The rule is:

NOTE:

There must be termination at both physical ends of the bus and only at the ends.

There are two main types of termination, active and passive. Active terminators reduce interference and allow faster data throughput. On devices with high transfer speeds, such as HP StorageWorks Ultrium devices, active termination is required, using an LVD or multimode active terminator. (Multimode terminators allow both LVD and single-ended devices to be connected to the same bus. They detect the type of bus and automatically supply the correct termination.)

StorageWorks drives, the ID is displayed on the rear panel and can be set by

HP StorageWorks drives, the ID is set on the back of the tape array, see Set

Normally the HBA forms one end of the SCSI bus and provides termination. You only need to ensure that the other end of the bus is terminated.

Removable drives

For HP StorageWorks Ultrium removable tape drives, termination is provided by connecting a terminator to the spare SCSI connector on the rear of the tape array. There are two connectors for each bay in the tape array. It does not matter which is used for SCSI-IN and SCSI-OUT.

If you have each removable drive in the tape array attached to a separate bus, then, for each bay in use, you must attach a terminator to the spare connector for each device.

If you a re using the removable drives to m irror backups, you can daisy-chain devices (but no more than two on each SCSI bus). Connect an LVD-rated c able from the spare SCSI connector for the ﬁrst device to one of the SCSI connectors for the second device and attach the terminator to the spare SCSI connector for the second device.

Refer to your tape array documentation for detailed instructions.

Internal drives

HP StorageWorks Ultrium internal tape drives do not supply termination. A suitably terminated LVD internal ribbon cable is supplied with the tape drive. The terminator is usually a small, rectangular block of plastic attached to the cable end and ma rked ‘SCSI Terminator’.

As long as this terminator is attached, you do not need to take any further action. However, if you have otherdevicesattachedtothecable,makesurethattheyhaveterminationremovedordisabled.

NOTE:

IfyouhaveaninternalandexternaldeviceattachedtothesameSCSIbus,theHBAwillbeinthemiddle of the cable and thus its termination must be disabled. See the host bus adapter’s documentation fordetailsofhowtodothis.

External drives

For HP StorageWorks Ultrium external tape drives the enclosure provides active termination.

As long as the drive is the only device on the SCSI chain, no terminators are required. The green ACT Term LED on the rear of the drive indicates whether auto-termination is active (on) or not (off).

Make sure the terminator is ﬁrmly attached to the SCSI-OUT connector on the rear of the device when you install it.

SCSI conﬁguration guide

Figure 26 SCSI termination on a single Ultrium tape drive

If you have more than one device on the SCSI bus, daisy-chain them by connecting an LVD-rated cable from the SCSI-OUT connector on the ﬁrst device to the SCSI-IN connector on the second device. Assuming you have two Ultrium tape drives connected, the enclosure on the second drive provides termination. The green ACT Term LED on the rear of the ﬁrstdrivewillbeoffwhileontherearoftheseconddriveit will be on. If the second device is not an Ultrium external drive, make sure that it is terminated using an LVD-rated multimode terminator.

Cable length

• For LVD SCSI the maximum length for a single device is 25 meters. For multiple devices, the

maximum combined internal/external length is 12 meters.

• If you h ave a combination of LVD and SE devices on the bus, the maximum cable length reverts to

the SE speciﬁcation. This is 3 meters for four or fewer devices, and 1.5 meters for m ore than four devices. See also note below on SE and LVD interfaces.

• For best performance, keep lengths to a minimum, but avoid very short overall lengths (less

than 0.5 meters).

tter in SCSI systems. There are two factors to consider: cable length and cable quality.

Cable

quality

• It is important to use good quality cables. Generally speaking, cable quality affects performance

and reliability. This is particularly true for external, shielded cables.

• Look

afteryourSCSIcables.Inparticular,takecarewhenconnectingordisconnectingnotto damage the high-density connectors. Avoid putting excessive twists in external shielded cables, as this can cause premature failure.

With internal devices

HP StorageWorks Ultrium tape drives have a 68-pin wide, high-density SCSI connector. A suitable cable with the correct termination is supplied with the tape drive. If you are using an HP StorageWorks Ultrium drive on an internal bus with other peripherals that run at Ultra2 speeds, it is important that a 68-pin LVD-compatible ribbon cable is used. Do not connect your tape drive to lower-rated SCSI or to narrow SCSI.

SCSI conﬁguration guide

With external devices

The cable provid a wide, very high density (VHD), LVDS SCSI connector.

If your server or host bus adapter is equipped with a high density (HD) wide SCSI connector, you will need to order a 68-pin VHD-to-HD converter or 68-pin VHD-to-HD cable. See h

For HP StorageWorks Ultrium removable tape drives, appropriate cables and terminators are provided with the tape array.

Note on SE and LVD interfaces

SE and LVD deﬁne how the signals are transmitted along the cable.

• With low volt

If you use LVD SCSI devices on the same bus as single-ended devices this will switch the LVD SCSI host adapter into single-ended mod e and restrict cable length.

If you connect only LVD SCSI devices, the bus will operate in low voltage differential mode and Ultra160 and higher speeds will be enabled. If you use a combination of Ultra160 and Ultra2 devices, each device wil
