1 LTO Ultrium drives in libraries

Introduction

This chapter contains information that relates to placing an HP LTO Ultrium drive in an automated device, such as an autochanger or a tape library:

• Drives for use in libraries have different front panels from drives mounted individually in servers

and standalone drives. There is also a special front panel for use in autoloaders. These are described on page 14.

• For notes on the requirements and other details for the installation of drives into libraries, see

page 16.

• For notes on the operation of drives in libraries, see page 20.

• For troubleshooting information, see page 22.

Chapter 2 contains information about using special features of LTO Ultrium drives in libraries:

• The “Automation and drive interface” (ACI/ADI) allows the activities of the drive to be

coordinated within a library. See page 25 for details.

• “Configuring autoload and library-controlled loads” on page 27 allows you to configure

whether automatic or ACI-controlled loads and unloads occur.

• LTO Cartridge Memory (LTO-CM) or Cartridge Memory is EEPROM memory that is embedded in

every LTO Ultrium tape cartridge. It is non-volatile and is contactless in that it is read by RF coupling rather than electrical contact.

• For suggestions of how to make use of cartridge memory in libraries, see “Using Cartridge

Memory (LTO-CM)” on page 30.

Backup software

You need backup application software that supports your LTO Ultrium drive and tape library.

Suitable backup applications will include driver software that establishes the interface between the tape drive and the software. Applications usually recognize tape drives by their manufacturers’ ID string rather than their model numbers, so check the following table for the appropriate reference.

The automation front panel has the following features:

• There is an eject button for manually ejecting a cartridge. Press this for approximately ten

seconds to start a “forced eject” for recovering a cartridge manually. See page 22 for details.

• Indicator LEDs provide a visible indicator of the state of health of the drive. See Chapter 6 on

page 69 for details.

• There is no door. Instead there are two fixed guides to guide the cartridge into the drive.

• There is access to a proprietary serial HP LTO diagnostics port. To access this port via RS232

requires an HP LTO Diagnostics Interface Card. Diagnostic information from the drive such as power-on hours, tape-pulling hours, error codes, and firmware trace-logs can be accessed by connecting to the serial communications port on a computer. Please contact HP for further details on this diagnostics port.

• The indent for a label on the left just under the cartridge opening is left blank, exposing two

holes. These can be used to provide a target for the optical position sensor of a library picker.

• There are additional holes around the cartridge opening to allow a throat to be fitted if

necessary, to help the smooth loading of cartridges.

Front panel for use in autoloaders

A special front panel is available for autoloader applications where the autoloader conforms to a 2U product height. The front panel fits within the drive form factor in height and width:

Installing drives

Airflow requirements

HP LTO Ultrium drives require forced airflow from front to back and, in the case of full-height drives, from back to front provided it does not exceed critical temperatures.

The required flow depends on the ambient air temperature:

• 6 cfm for ambient air temperatures fluctuating in the range 10°C–35°C.

• 8 cfm for ambient air temperatures fluctuating in the range 10°C–40°C.

Measuring internal drive temperatures

FC and SCSI drives

The recommended method of measuring the temperature of critical components is to read the “Max temperature since cartridge loaded” after exercising the drive by writing data at the maximum data rate for a period of at least one hour. This temperature correlates closely with the temperature of the most critical ICs.

If the airflow is adequate, the maximum temperature at the sensor should be no more than 20°C above ambient.

The maximum temperature at the sensor should be:

• <31°C above ambient for 40°C maximum temperature ambient environment

• <36°C above ambient for 35°C maximum temperature ambient environment

This equates to:

• <71°C at 40°C ambient (8 cfm airflow)

• <71°C at 35°C ambient (6 cfm airflow)

Extracting internal temperature information

You can extract the “Max temperature since cartridge loaded” reading via the main interface or via the ACI/ADI send_scsi command as follows:

1. Send a

1D 10 00 00 08 00 93 00 00 04 00 00 20 2A

2. Send a

1C 01 93 00 44 00

3. The “Max temperature since cartridge loaded” value is ASCII encoded in bytes 22–29 of the

incoming data. Example SCSI trace:

SendDiagnostic |1D 11 00 00 08 00 |00008|00|00|

ReceiveDiagResults |1C 01 93 01 00 00 |0009C|00|00|

4. Translate each character received from ASCI to hex numbers.

For the example above: 30 30 30 30 31 41 37 34 = 00001A74h

5. Convert this number to decimal = 6772

6. Divide this number by 256 to give the temperature in °C = 26.45°C

FC and SCSI drives

A method for approximating the air flow for LTO Ultrium drives is to use the drive’s Primary Temperature Sensor (PTS).

1. Exercise the drive by writing data at the maximum data rate for a period of at least 45 minutes.

2. Find the PTS reading as in the previous section, ”Extracting internal temperature information”.

3. Subtract the ambient air temperature in which the drive was run from this PTS temperature.

4. Use this temperature rise above ambient to find the required air flow for the drive using the

following graph. Because of variations in the temperature sensor (PTS) reading between drives, you are recommended to average readings from four different drives to obtain the best results.

Rear panel and connectors

FC Drives SCSI Drives SAS Drives

CAUTION: LTO Ultrium tape drives are not installable or replaceable by end-users, so the

attachment or removal of FC, SCSI, SAS, power and ADI cables between the tape drive and the tape library should only be carried out be service-trained personnel authorized by the tape library supplier. The connectors are not field upgradeable.

The rear panel contains the connectors that allow the tape drive to communicate with the tape library and host computer system. The panel includes the following connectors:

On all drives:

• Power connector

A standard 4-pin power connector used to supply the 5V and 12V power the tape drive.

• ADI connector (for automation use)

For details of the ADI connector, see page 80. For details of the use of the ADI connector in libraries see ”Automation/Drive Interface (ADI)” on page 26.

• Diagnostic Serial port connector

The proprietary serial HP LTO diagnostic port. To access this port via RS232 requires an HP LTO Diagnostic Interface Card. Diagnostic information from the drive can be accessed by connecting to the serial communications port on a computer. Contact HP for further details on this diagnostic port and its function.

On Fibre Channel drives:

• Fibre Channel connectors

Two Small Form Factor Pluggable (SFP) duplex-LC fibre channel transceivers. Depending on the specific configuration, only one SFP FC transceiver may be installed. For details see page 80.

• AL_PA connector

A 2x7-pin auxiliary connector used to set a specific Arbitrated Loop Physical Address (AL_PA). Two pairs of pins can also be used to power remote transceiver status LEDs. For details see ”Fibre Channel addressing” on page 78.

On SCSI drives:

• SCSI connector

A standard 68-pin high-density SCSI connector. The SCSI cables may be installed in a daisy-chain configuration linking two or more LTO Ultrium tape drives on the same SCSI bus.

• SCSI address connector

A 12-pin auxiliary connector used to set the SCSI ID. Each device on the SCSI bus must have a unique SCSI ID set by the SCSI address connector or by the tape library.

On SAS drives:

• A standard internal SAS connector

An HP LTO4 SAS tape drive should be powered from the normal power connector and not through the power port of the SAS connector. The power port on the SAS connector is not connected to the tape drive.

Fixing dimensions

The positions of fixing points are shown below.

The recommended screw length depends on the thickness of the rails or enclosure into which the drive is mounted:

Server or Rail Thickness Recommended Screw Length

> 1.5 mm ≤ 2.0mm M3 x 6.0mm

> 1.0 mm ≤ 1.5 mm M3 x 6.0 mm

Cleaning

When the drive needs cleaning, the orange ‘Clean’ LED on the tape drive will flash. Only insert an HP Ultrium Universal cleaning cartridge into the tape drive when the LED flashes.

The tape drive also tells the automation controller that a cleaning tape needs to be used via the ADI connector.

See ”Automation and drive interface” on page 25 for details of ACI commands.

CAUTION: Only use LTO Ultrium Universal cleaning cartridges with HP LTO Ultrium tape drives. Do

not use swabs or other means of cleaning the heads.

To clean the heads:

NOTE: HP recommends that you use the HP LTO Ultrium Universal cleaning cartridge C7978A

(Orange).

LTO Ultrium Universal cleaning cartridges can be used up to 50 times.

1. Insert a cleaning cartridge into the drive. The tape drive automatically loads the cartridge and

cleans the heads. If the cleaning cartridge ejects or returns to the ready-to-eject position immediately with the Tape

Error LED on, it has expired or it is not an LTO Ultrium Universal cleaning cartridge (or is an older unsupported LTO Ultrium 1 cleaning cartridge). In this case, discard the cleaning cartridge and repeat the operation with a new one.

The cleaning cycle can take up to 3 minutes, during which the orange ‘Clean’ LED will be on steadily and the green ‘Ready’ LED will flash. When it has finished, the drive ejects the cartridge or returns the cartridge to the ready-to-eject position.

Resetting drives

The tape drive can be reset by the automation controller via the ADI connector or by pulling the ACI_RST_L line low (see page 80).

There are two levels of reset via the ADI connector:

• ACI reset—resets the ACI port and all Fibre Channel, SCSI or SAS ports

• Drive reset—equivalent to a power-on reset

Either reset method will interrupt the interface between the drive and host. A reset may result in no End of Data mark being written. As a result, it is strongly recommended that a reset command is not sent unless all other recovery methods have failed. Note that certain automation commands (Load, Unload, Set Drive Configuration, Reset and Set Baud Rate) can be queued behind outstanding SCSI commands giving the impression that the drive has stopped responding over the ADI connector. (All command packages will be still be ack’ed even though the command will be queued.)

HP LTO Ultrium 4 drives technical reference manual, volume 1: hardware integration 21

HP restricted

Page 22

Following a Reset command with reset control set to Drive Reset or after pulling the ACI_RST_L line low, the drive will behave as if it has powered up and will go off bus and lose all ADI connector configurations.

An FCP reset will not affect the ACI interface.

Note that following an upgrade of the drive firmware, the drive will be reset as if it had been powered up.

Troubleshooting

If you experience problems when using your tape drive within an automation environment, you need to isolate the cause of the problem. For example, if you have just installed a new SCSI host bus adapter in your host system and your system will not start, the cause of the problem is likely to be the adapter.

The first step in problem-solving is establishing whether the problem lies with the cartridge, the drive, the tape library, the host computer and its connections, the operating system or backup application on the host, or operator error.

Please refer to troubleshooting information provided with the tape library, the host or the backup software if the problem seems to lie in one of these areas.

If none of the following advice helps you solve the problem, contact your tape library supplier.

Diagnostics

HP LTO Ultrium tape drives continuously monitor and gather information such as tape-pulling hours, power-on hours, usage information on cartridges, firmware trace-logs, and error logs. These can be used to aid health checks and diagnosis in cases of failure. Data can be extracted via:

• The main host interface

• The ADI connector

• The serial diagnostics port using a proprietary serial interface application.

Contact HP for a copy of the Diagnostics Extraction Guide on extracting and interpreting the information.

Interpreting the LEDs on individual drives

HP LTO Ultrium tape drives have four LEDs on the front. See Chapter 6 on page 69.

Forced eject

If a cartridge fails to eject using the normal unload procedure, press and hold the Eject button for 10 seconds. This instructs the drive mechanics to perform an emergency unload. Wait for the cartridge to be ejected. This may take up to 15 minutes (the maximum rewind time).

If the cartridge is still jammed, press the emergency reset button (see page 14) or perform an emergency reset by pressing and holding the Eject button for 20 seconds. The drive will reset when you release the button. Wait for the drive to reset and get back to the loaded position. This may take up to 15 minutes. Again press and hold the Eject button for 10 seconds to perform a second forced eject and emergency unload.

Cleaning issues

Use the following table to resolve cleaning problems:

Problem Solution

Recurring cleaning message.

A brand new data cartridge is used, and the library operator panel indicates that cleaning is required.

The cleaning cartridge is ejected immediately after loading.

Clean the drive with an LTO Universal Cleaning Cartridge as instructed in the tape library documentation. If the message reappears, replace the cleaning cartridge with a new one.

If the message reappears when a particular data cartridge is used, verify that the data cartridge is readable by clearing the message and reading the tape again.

If the data cartridge can be read, back up the data to another cartridge and then discard the damaged one.

Clean the outside of the data cartridge with a barely damp, clean, lint-free cloth. Clean the drive as instructed by your tape library documentation.

If the operator panel indicates cleaning is required within a short period of time, replace the data cartridge.

Make sure that you are using an approved LTO Ultrium Universal cleaning cartridge and that the cleaning cartridge is not expired.

2 Using special features in libraries

Introduction

This chapter contains information that relates to placing an HP LTO Ultrium drive in an automated device, such as an autochanger or a tape library.

• The “Automation and drive interface” described below allows the activities of the drive to be

coordinated within a library.

• “Configuring autoload and library-controlled loads” on page 27 tells you how to configure

whether automatic or library-controlled loads and unloads occur.

• “Using Cartridge Memory (LTO-CM)” on page 30 describes the EEPROM embedded in every

LTO Ultrium tape cartridge, part of which is available for use by applications.

Drives for inclusion in automated devices have different front panels from individual drives.

Automation and drive interface

The interface between the tape drive and the library will support both the Automation Control Interface (ACI) and the Automation/Device Interface (ADI) standards. Typically the interface support will be an OEM selection. For convenience, the connector is referred to as the ADI Connector in this manual.

NOTE: ADI is covered by two T10 standards:

• For ADT: ANSI INCITS 406-2005

• For ADC: ANSI INCITS 403-2005

Automation Control Interface (ACI)

The Automation Control Interface (ACI) allows the activities of the drive to be coordinated within a library. The protocol has been designed so that it can be made into a standard feature of tape drives. It provides a rich and extensible functionality to allow automation manufactures to add value in their application of it.

The interface is a serial bus with additional control lines, designed to connect the LTO Ultrium tape drive to an automation controller in a tape library. Each tape drive position has a separate automation controller. The ADI RS-422 serial port on the rear of the drive allows for ACI connection.

The ACI protocol provides the following fundamental functions:

• Coordinating the automation controller and the tape drive for Load and Unload operations

• Allowing the automation controller to retrieve information from the tape drive

• Setting tape drive configuration information

In addition, the following functions may be supported depending on the way that the tape library is configured:

HP LTO Ultrium 4 drives technical reference manual, volume 1: hardware integration 25

HP restricted

Page 26

• Providing upload and download of firmware images

• Providing access to the contents of the Cartridge Memory

• Providing a protocol for passing SCSI commands from the host to the tape drive

• Providing a protocol for passing SCSI commands from the host to the library (Surrogate SCSI)

NOTE: These notes refer to the “standard” automation drive variant.

For details of using ACI commands and the ACI protocol, see Chapter 5 of the Software Integration Guide, volume 2 of the HP LTO Ultrium Technical Reference Manual.

Automation/Drive Interface (ADI)

The INCITS T10 (SCSI) committee has a working group devoted to the development of a common Automation-Drive Interface (ADI). ADI consists of two standards:

• Automation/Drive Interface—Commands (ADC), ANSI INCITS 406-2005, which specifies the

SCSI command set used over ADI.

• Automation/Drive Interface—Transport Protocol (ADT), ANSI INCITS 403-2005, which specifies

a transport protocol for ADI.

The drive operates in either ACI or ADI mode. It is not possible to interleave ACI and ADI commands because they are handled very differently. The drive defaults to ACI mode after a power-on or hard reset. The Automation Controller can then instruct the tape drive to switch to ADI mode by sending a Port Login frame under the following conditions:

1. No ACI commands are outstanding. This not only means that the tape drive must have received

acknowledgement for all responses to all ACI commands received, but also that all immediate response commands have also finished. For example, if an Automation Controller initiates an immediate response Load command (see section 5.3 of ACI specification), it cannot issue an ADI command until the tape drive has finished physically loading the cartridge. If an ACI command is outstanding when an ADI frame is received the drive will transmit an ACI <NAK> character in response.

2. An Encoded ADI frame received when the tape drive is in ACI Mode must not exceed the

Receive Buffer size (see section 5.16 of the ACI Specification for details) and the frame must be received within the ACI Transmission Period (see section 4.6.6.3.2 of the ACI Specification). If either of these conditions is exceeded the tape drive will transmit a <NAK> character.

3. ADI frames received in ACI Mode must be Port Login frames otherwise the tape drive will revert

to ACI Mode after transmitting the appropriate ADI response.

4. The ADI protocol must be enabled; see the Set Drive Configuration command (section 5.6 of the

ACI Specification) for details. If the tape drive receives an ADI frame when the ADI protocol has been disabled the drive will transmit a <NAK> character.

When the tape drive is in ADI Mode it will not acknowledge or respond to any ACI command until the ADI port becomes logged out, either with an explicit Port Logout frame or an ADI Reset.

When the tape drive transitions from one mode to the other (ACI to ADI or ADI to ACI) it will not implicitly change the drive’s configuration. However, Automation/Drive Interface [ADC] SCSI mode

Using special features in libraries26

HP restricted

Page 27

parameters only apply when the tape drive is in ADI Mode, so the tape drive behavior may change after transitioning between the two modes.

HP recommends that the drive is used in either exclusively ACI or ADI modes of operation. Avoid mixing operation of the two modes.

Configuring autoload and library-controlled loads

HP LTO Ultrium tape drives can be configured so that loads either occur automatically or under the control of the library. A SCSI is byte 5, bits 0–2 of the Control Mode page, 0Ah.

If the Autoload field = 0, Autoload is set and the drive automatically loads a cartridge when it is inserted and threads the tape so that it is ready for use.

MODE SELECT command can set the Autoload field to do this. The field

If the Autoload field = 1 or 2, the drive pulls the cartridge into the drive but does tape. In this position, the LTO-Cartridge Memory can be read. The drive requires a Load command to thread the tape and make it ready for use.

Cartridge positions during load and unload

The following diagrams show the positions of importance during load and unload.

Eject Point Cartridges are ejected to this point. It is 20.9 mm beyond the front panel

and 26.1 mm beyond the front of the mechanism. The position tolerance is ±1 mm. The automation controller cannot configure the location of this position.

Load Point 1 If Autoload is set (Autoload field = 0), the drive will start to load the

cartridge when it reaches this point.

If Autoload is not set (Autoload field = 1 or 2), the library must insert the cartridge into the drive to a position between Load Point 1 and Load Point 2 and preferably closer to Load Point 1. The library can then issue a Load command via the ADI connector to instruct the drive to load and thread the cartridge.

Load Point 2 The maximum distance a cartridge can be inserted for optimal loading

There is one other point of note, the ready-to-eject position. If Auto-Eject is not set then when an unload command is received by the drive, the tape will be rewound and unthreaded. The drive will then wait at this point until it is commanded to eject the cartridge by the ACI Unload command.

Load scenarios

The following scenarios describe the operation during the various types of load.

Load scenario 1: Autoload

1. The library sends a Set Configuration command to enable Autoload. This is only necessary after

a drive power-on.

2. The host sends a Move Medium command to the robotics.

3. The picker gets a cartridge from a storage slot.

4. The picker inserts the cartridge into the drive aperture.

5. The picker pushes the cartridge to at least Load Point 1.

6. The drive automatically takes the cartridge, loads it and threads it.

Load scenario 2: Library controlled

1. The host sends a Move Medium command to the robotics.

2. The picker gets a cartridge from a storage slot.

3. The picker inserts the cartridge to between Load Point 1 and Load Point 2.

4. The picker lets go of the cartridge.

5. The library sends a Load command to the drive.

6. The drive takes the cartridge, then loads and threads it.

Unload scenario 1: Autoload

1. The library sends a Set Configuration command to enable Auto-Eject. This is only necessary after

a drive power-on.

2. The host sends an Unload command to the tape drive.

3. The drive rewinds, unthreads and ejects the cartridge to Eject Point.

4. The host sends a Move Medium command to the robotics.

5. The picker takes the cartridge from the tape drive and places it in its storage slot.

Unload scenario 2: Library controlled

1. The host sends an Unload command to the drive.

2. The drive rewinds and unthreads the tape. It then pauses with the cartridge at ready-to-eject

position.

3. The library sends an Unload command to eject the cartridge.

4. The drive ejects the tape to Eject Point.

5. The picker takes the cartridge from drive and places it in its storage slot.

Load forces

The unload force is 4.45N maximum; this is the force that an external mechanism must exert to remove a fully ejected cartridge from the drive.

The load force varies according to the speed at which the cartridge is inserted into the drive. The peak load force occurs when the cartridge begins to accelerate the drive carrier and only lasts for a short time. The following graph plots examples of peak load force against load speed:

Using Cartridge Memory (LTO-CM)

Linear Tape Open—Cartridge Memory (LTO-CM) is an EEPROM that is embedded in every LTO Ultrium tape cartridge. It is non-volatile and is contactless in that it is read by inductive coupling rather than electrical contact.

The Cartridge Memory is used to store the tape directory and diagnostic and log information. Because of the speed at which it can be read, load and unload times are reduced, information is found on the tape more quickly and fewer tape passes are needed, increasing tape reliability.

The memory is primarily designed to speed up internal operations in the drive, but it also contains free space that can be used by application software. This may be used to store “common” information (shared by all software vendors) and “vendor-unique” information (specific to the application).

Hosts can use this free space using the SCSI Write Attribute and Read Attribute commands. For information on these commands, see Chapter 4 of Interface Guide, Volume 3 of this HP LTO Ultrium Technical Reference Manual.

To support CM fully, software vendors should ensure that their company names are registered with ANSI T10 or the National Committee for Information Technology Standards (NCITS) as they are now known. The list of Vendor IDs is displayed at http://www.t10.org/lists/vid-alph.htm also contains details of how to get a new name assigned.

Cartridge Memory adheres to the Media Auxiliary Memory (MAM) standard. “MAM” indicates that the access method applies to all types of media, not just LTO Ultrium.

The MAM standard provides for the storage and access of information held as a set of pre-defined and user-definable attributes that are divided into six main sections:

, which

• Media Common Section—hard-coded by the media manufacturer.

For example: manufacturer’s name, cartridge serial number, length, media type

Using special features in libraries30

HP restricted

Page 31

• Drive Common Section—updated by the drive every time it accesses the media.

For example: maximum and remaining tape capacity, TapeAlert flags

• Host Common Section—updated by the host’s software application every time it uses the media.

For example: software application vendor’s name and version, media text label, date last written

• Media Vendor Unique Section—optional information written by the media vendor for their own

purposes. Unique to the media vendor.

• Media Vendor Unique Section—optional information written by the media vendor for their own

purposes. Unique to the media vendor.

• Host Vendor Unique Section—space reserved for use by software applications for their own

purposes. Unique to the software vendor. Approximately 1 kilobyte.

For details of SCSI commands relating to Cartridge Memory or MAM, see Read Attributes (8Ch) and Write Attributes (8Dh) in the Interface Guide.

Use in libraries

Cartridge memory offers possibilities for use in libraries as an adjunct to or replacement for barcodes. The following diagram shows the architecture required. HP is working to provide a standard module with this functionality via a third party.

However, because Cartridge Memory has space that can be written by applications, it can hold details of the contents and nature of the tape. This obviates the need for this information to be held by the application. HP is working with other industry leaders, both hardware and software, on an Industry Common Implementation Guide.

3 Drives in tape arrays

Installing drives

Identifying the drive

The model name is on the front panel and the product and serial numbers are on a label attached to the drive.

Modes of usage

Tape arrays can be used in different system configurations; direct attach, network attach and attached to a Storage Area Network (SAN). For details of these see page 83.

Attaching to Fibre Channel

When installing a SCSI drive on a fibre channel direct attach network or SAN configuration, you need a fibre channel/SCSI router. Check www.hp.com manual does not describe how to configure your fibre channel infrastructure or SAN network to use the tape array. This is a complex area and users are advised to refer to their SAN documentation or contact their SAN system administrator or supplier for technical support.

Attaching to SCSI

HP LTO Ultrium SCSI drives are high performance Ultra 3 SCSI devices designed to operate on a low voltage differential SCSI bus (LVDS). They are installed in a tape array in a rack-mount system and can be connected to a SCSI connection on a server or fibre channel/SCSI router. To get optimum performance from your tape drive you need a SCSI bus that can transfer data at a rate that supports the tape drive’s maximum transfer speed. We recommend an Ultra 3, 160 and 320 SCSI bus.

for the latest ordering information. This

Attaching to SAS

HP LTO Ultrium SAS drives are high performance 3 GB SAS devices. When installed in a tape array in a compatible rack mount system they can be connected to a SAS connection on a server or to an expander as part of a larger SAS network. To get the optimum performance from your tape drive you need a SAS topology that can transfer data at a rate that supports the tape drive's maximum transfer speed.

Appropriate HP rack-mount systems

HP LTO Ultrium removable tape drives are used in conjunction with the HP StorageWorks Tape Array 5300 system, which will hold up to two full-height drives.

The tape array is designed to be installed into any compatible 19” rack-mount systems. It must be properly installed and configured. Refer to your tape array documentation for further details.

Airflow requirements

As long as the tape array is fully populated, it will provide adequate airflow for HP LTO Ultrium drives.

HP LTO Ultrium 4 drives technical reference manual, volume 1: hardware integration 33

HP restricted

Page 34

If you have unused bays in the tape array, you must install the blanking plates provided with the tape array. This ensures that there is adequate airflow to the drives. See the documentation with the tape array for details on installing blanking plates.

You should ensure that ventilation is adequate at the front and rear of the tape array.

HP LTO Ultrium drives require forced airflow, either from front to back or from back to front.

The required flow depends on the ambient air temperature:

• 6 cfm for ambient air temperatures fluctuating in the range 10°C–35°C.

• 8 cfm for ambient air temperatures fluctuating in the range 10°C–40°C.

For details of how to test if the airflow is adequate, see “Airflow requirements” on page 16.

Setting the SCSI ID

For removable drives installed in an HP StorageWorks Tape Array 5300 rack enclosure, set the SCSI ID at the appropriate switch on the rear of the tape array. Each drive should have a unique ID. The number of address switches corresponds to the number of tape drives that can be inserted into the tape array, so the HP StorageWorks Tape Array 5300 has four SCSI ID switches to enable the installation of up to four half-height tape drives. When installing two HP LTO Ultrium full-height tape drives, use the SCSI ID switches 1 and 2 only.

Termination

Both ends of a SCSI bus must be terminated.

Assuming that the host bus adapter is already correctly terminated, there are typically two possibilities:

• The tape drive is being connected in a direct one-to-one configuration to the host

server—termination must be used.

• The tape drive is being daisy-chained with other tape devices onto the host server—only the last

device must be terminated.

The terminator can be plugged directly onto either of the two SCSI connectors on the rear of the tape array. Terminators must be ordered separately.

Drives in tape arrays34

Inserting a drive

1. Ensure that the extractor lever on the drive is in the

out position, as shown in the picture.

2. Lift the drive carefully.

3. Align the rear of the drive with the guides on the side

of the HP StorageWorks Tape Array 5300.

4. Slide the drive along the guides until the connectors

on the back mate with the connectors at the back of the enclosure.

5. Push the extractor lever in until it locks the drive in

position.

Connecting to a Fibre Channel router or by SCSI/SAS to a server or router

Individual SCSI tape drives are connected to their host server or fibre channel router 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.

Individual SAS tape drives are connected to their hosts via the SAS connectors on the back of the tape array. They do not require any SAS cables to plug into the array. However, cabling is required to connect the tape array with the SAS host or expander.

Fibre Channel connection

If you are using your SCSI tape drive on a fibre channel (FC) network, you will need a FC/SCSI router with a spare LVDS SCSI port. The router should be connected via a 68-pin, wide, LVDS-rated cable to the tape array. Refer to our web site at www.hp.com/go/connect recommended FC/SCSI routers and cables. If you are attaching your tape drive to a SAN environment supplied by HP, refer to your SAN solution collateral or configuration guides for further details.

Server SCSI connection

If you are attaching the drive to a server, you will need a properly installed and configured SCSI host bus adapter (HBA) or a built-in SCSI controller on your server with a spare LVDS SCSI port. For optimum performance your tape drive should only be connected to an Ultra 3, 160 or 320 host bus adapter or SCSI controller.

The server should be connected via a 68-pin, wide, LVDS-rated cable to the tape array. The standard, recommended configuration is a direct, one-to-one SCSI connection between the tape drive and the host server so that the drive is the only device on the SCSI bus. It is possible to daisy-chain two tape drives together within the tape array, but to preserve performance, this should only be done if the drives are on an Ultra 3, 160 or 320 SCSI bus. Do not daisy-chain more than two drives together, as this will degrade their individual performance with respect to transfer rate.

Do not attach the drive to the same SCSI bus as your disk drive or RAID controller.

Server SAS connection

If you are attaching the drive to a server, you need a properly installed and configured SAS host bus adapter (HBA) or a built-in SAS controller on your server with a spare SAS port. For optimum performance your tape drive should only be connected to a 3 GB SAS host bus adapter or SAS controller, but the drive will also work with a 1.5 GB SAS connection.

Replacing a drive

HP LTO Ultrium removable drives can be removed and replaced without powering down the tape array and without interrupting operations to the other drives in the array. However, note the following:

• In Berkeley mode, the tape position will remain unchanged by a device close operation.

• In AT&T mode, a device close operation will cause the tape to be repositioned just after the next

tape filemark (the start of the next file).

If all drives in the tape array are powered up when the system is turned on, the host will be aware of those drives. You can remove any drive and replace it with another without disrupting the system.

If a drive is not powered up or you place a drive in an empty slot after the system has been powered up, the system will have to be reset before the host will recognize the drive.

Removable drives allow modules to be replaced while powered up as long as no data is being transmitted from the system to the module or vice versa. The SCSI IDs are controlled by the tape array, not the drives, so if you remove a drive and replace it with another the ID will not change.

Removing a drive

Installing a new drive

See the instructions in “Inserting a drive” on page 35.

Operating the drive

Removable drives are powered on when you switch on your tape array and computer.

Drives in tape arrays36

1. Pull the extraction lever of the drive that you want to

replace so that it is in the out position.

2. Using the extraction lever, pull the drive gently and

firmly out of the tape array.

The tape drive will run its hardware self-test. During the test the ‘Ready’ LED flashes and all the other LEDs are off. On successful completion the ‘Ready’ LED is on. If the self-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.

• If you have just installed the drive, check the installation for loose connections, reset the drive

and repeat the self-test.

• Try the “Troubleshooting” on page 39 to determine what the problem is.

• If the fault condition persists, call for assistance.

Loading a cartridge

Use HP LTO Ultrium cartridges with your drive.

1. In HP StorageWorks Tape Arrays:

Insert the cartridge into the slot in front of the drive with the white arrow on the top facing the drive door. The toothed drive hub is on the bottom of the cartridge.

2. Apply gentle pressure on the rear of the cartridge until the drive takes the cartridge and loads it.

The ‘Ready’ LED flashes green while the drive performs its load sequence. When the cartridge is loaded, the ‘Ready’ LED shows steady green.

Do not try to force the cartridge if it does not load properly. The drive will eject the cartridge after about 10 seconds so you can load it again.

Unloading a cartridge

1. Press the Eject button on the front panel.

During the unload sequence the ‘Ready’ LED flashes green. The drive completes any task it is

currently performing, rewinds the tape and ejects the cartridge. Once the tape has rewound, the eject cycle will take less than 13 seconds.

2. Remove the cartridge and store it in its plastic case in a cool, dry atmosphere.

Cleaning the drive

CAUTION: It is essential to use only LTO Ultrium Universal cleaning cartridges with HP LTO Ultrium

tape drives as other format cleaning cartridges will not load and run. Use of HP cleaning cartridges will ensure your tape drive is fully protected. Do not use swabs or other means of cleaning the heads.

When the drive needs cleaning, the orange ‘Clean’ LED on the tape drive will flash. Only insert a cleaning cartridge into the tape drive when the LED flashes.

The drive’s TapeAlert feature will send a message to your backup application when the tape heads need cleaning or a cleaning cartridge has expired.

LTO Ultrium Universal cleaning cartridges can be used up to 50 times.

To clean the heads:

1. Insert a cleaning cartridge into the drive. The tape drive automatically loads the cartridge and

cleans the heads. If the cleaning cartridge ejects immediately, it has expired or it is not an LTO Ultrium Universal

cleaning cartridge (or is an older LTO Ultrium 1 cleaning cartridge). In this case, discard the cleaning cartridge and repeat the operation with a new one.

The cleaning cycle can take up to 3 minutes, during which the orange ‘Clean’ LED will be on and the green ‘Ready’ LED will flash. When it has finished, the drive ejects the cartridge.

2. Remove the cleaning cartridge from the drive.

Troubleshooting

Emergency unload

If a cartridge fails to eject using the normal unload procedure, press and hold the Eject button for 10 seconds. This instructs the drive mechanics to perform an emergency unload. Wait for the cartridge to be ejected. This process may take up to 15 minutes (the maximum rewind time).

If the cartridge is still jammed, press the emergency reset button (see page 38). Wait for the drive to reset and get back to the loaded position. This process may take up to 15 minutes (the maximum rewind time). Again press and hold the Eject button for 10 seconds to perform an emergency unload.

General guidelines

The first step in problem-solving is establishing whether the problem lies with the cartridge, the drive, the host computer and its connections, or with the way the system is being operated.

Most modern host bus adapters locate and display attached devices when the system is booting up. On Windows systems, if you swap or connect a product when your system is running, you will need

HP LTO Ultrium 4 drives technical reference manual, volume 1: hardware integration 39

Page 40

to reboot the system. IA32 systems also usually need to be rebooted. UNIX systems may have pluggable drivers, which allow drives to be attached to a running system and detected without rebooting.

If the device is not detected on boot up, there is probably a problem with the physical hardware: cables, termination, connections, power or the host bus adapter. If the device is displayed during boot up but cannot be found in the operating system, this is more likely to be a software problem.

Problems with the host computer

Most modern host bus adapters locate and display attached devices when the system is booting up. If the device is not detected at this stage, there is probably a problem with the physical hardware: cables, termination, connections, power or the HBA itself.

If your drive is found on system boot up but cannot be found in the operating system, this is more likely to be a software problem.

Computer does not boot up

Possible Cause Potential Solution

You have connected the tape drive to an existing SCSI bus that has other devices connected to it and the SCSI address of the drive is identical to the address used by another device.

You have installed an additional host bus adapter and its resources are clashing with an existing adapter.

You have disconnected the power or cable from the computer’s boot disk during the drive installation process.

Computer boots, but does not recognize the drive

Possible Cause Potential Solution

The power or interface cable is not connected properly.

The SCSI bus is not terminated correctly.

Check that the cables to the tape drive are firmly connected. Ensure that the interface cable is LVDS-compliant and that it does not have any bent pins or is damaged. Replace, if necessary.

Check that the SCSI bus is actively terminated. (Refer also to the documentation for your SCSI controller and any other SCSI devices you may have.)

Make sure that each device on the SCSI bus has a unique ID. We recommend that the tape drive is connected to a dedicated host bus adapter. Do not connect the drive to a disk RAID controller as this is not supported.

Remove the new host bus adapter and check the server documentation.

Check that the cables to all devices are firmly connected.

The tape drive’s SCSI ID address is not unique.

Problems with the drive and cartridge

Tape drive does not work

Possible Cause Potential Solution

The drive is not receiving power from the tape array.

• Check the tape array is connected to a power source and switched

on.

• Check the drive is properly inserted into the tape array so that it

mates with the connections at the rear of the enclosure. The extraction lever should be pushed in, locking the drive in position.

• If the drive ‘Ready’ LED is still off, call for assistance.

There is a fault with the drive.

If possible, and if no other drives in the tape array are in use, try resetting the drive, or turning the power switch on the tape array off and then on again. (If there is a tape cartridge loaded in the drive, try to unload it by pressing the Eject button. If this succeeds, switch the tape array off and then on again.

If the problem persists, call for assistance.

The computer no longer recognizes the drive

Possible Cause Potential Solution

You powered up the drive or added it to the tape array after the host system was turned on.

You changed the drive’s SCSI ID after the host system was turned on.

The host computer system only identifies which IDs are present on SCSI buses after power-on or a reset. To make the host look for devices on the bus, you need to reset the host. You should be able to do this using the SCSI management software on your computer. As a last resort, you could turn the host system off and on again

• If you have replaced a drive that was recognized by the host, the

host should recognize the new drive at the same SCSI ID as its predecessor.

• If you make any changes to SCSI IDs (on the back on the tape

array), you need to reset the bus for the host to recognize the changes.

The drive is not inserted correctly.

Page 42

Possible Cause Potential Solution

The SCSI bus is not terminated correctly.

• Check the SCSI cable from the tape array is firmly connected to

the SCSI connector in the computer.

• If there are other devices in the SCSI bus, make sure that each

device has a unique ID.

• If there is more than one SCSI bus attached to your system, check

that the system is looking for the drive on the correct SCSI bus.

• Make sure that the bus is terminated correctly. If the array is the

only device or the last device on the bus, it must have a terminator fitted. If some other device is last on the bus, it should have a terminator fitted and the tape array should not.

There is a fault with the host system.

• Make sure that the system is configured to recognize the correct

device at each SCSI ID.

• Ensure that the correct driver for the tape drive is installed. Look at

the SCSI host adapter documentation and backup software documentation for further advice.

The application does not recognize the drive

Possible Cause Potential Solution

The application does not support the tape drive.

Check the drive is installed properly. Refer to our World Wide Web site (www.hp.com/go/connect support HP LTO Ultrium tape drives. Load any service packs as necessary.

Page 43

The cartridge will not eject

Possible Cause Potential Solution

The cartridge is jammed in the drive, or the backup application cannot eject the cartridge.

This is most likely to be a communication problem between the drive and the system.

Check there is power to the drive.

If the cartridge fails to eject using the normal unload procedure, press and hold the Eject button for 10 seconds. Wait for the cartridge to be ejected. This may take up to 15 minutes (the maximum rewind time).

If the cartridge is still jammed, perform an emergency reset by pressing and holding the Eject button for 20 seconds. The drive will reset when you release the button. Wait for the drive to reset and get back to the loaded position. This may take up to 15 minutes. Again press and hold the Eject button for 10 seconds to perform a second forced eject.

If the cartridge is still jammed, call for support.

The drive will not accept a cartridge or ejects it immediately

Possible Cause Potential Solution

The cartridge may have been damaged, for example dropped, the cartridge memory may be corrupted or the drive may have a fault.

1. Check the drive has power (the power cable is properly

connected and the ready LED is on).

2. Check you are using LTO Ultrium 2, 3 or 4 media. DLT cartridges

are not compatible with LTO Ultrium drives. See Chapter 9 on

page 87.

3. Make sure that you have loaded the cartridge with the correct

orientation (see “Front panel features” on page 37.)

4. Check for damage to the media (to the cartridge case, leader pin

or cartridge teeth) and discard it if it is damaged.

5. Use another cartridge that you know is good and see if it loads. If

it does, the original cartridge is faulty and should be discarded.

6. Check if another drive will accept the cartridge. If it does, the

original drive may be faulty. Before calling customer service, please check that the tape drive is responding and that it can be seen on the SCSI bus.

4Internal drives in servers

For the physical specification of the drive, see Chapter 1, “Physical Specification” in Specifications, Volume 4 of the HP LTO Ultrium Technical Reference Manual.

If you are installing the tape drive on a UNIX system, refer to the UNIX Configuration Guide, Volume 5 of the HP LTO Ultrium Technical Reference Manual.

Installing an internal drive into a server

Full details of how to install an internal LTO Ultrium tape drive into a server drive bay is given in the Getting Started Guide.

Identifying the model

The model name is on the front panel and the product and serial numbers are on a label on the top of the drive.

Standards and safety

Use the drive only in equipment where the suitability of the combination has been determined by an appropriate certification organization (such as Underwriters Laboratories Inc. or the Canadian Standards Association in North America, and the British Standards Institution or Verband Deutscher Elektrotechniker in Europe). Other considerations include the following:

1. A drive must be installed in an enclosure to limit an operator’s access to live parts, to provide

system stability, and to give the drive the necessary grounding integrity.

2. A drive must only be supplied by a Safety-Extra-Low-Voltage (secondary) circuit in accordance

with DIN VDE 0805. During incorporation of the equipment, all requirements of DIN VDE 0805 must be observed and obeyed.

NOTE: The drives are only fused to protect them from excessive currents.

Requirements

Mounting requirements

Drives require one industry standard 5¼-inch, full-height bay.

HP recommends 0.3 mm mounting clearance around all covers for isolation mounting movement.

For many servers, no mounting tray or rails are required. Devices simply slide into the computer’s chassis and are fixed with screws. Other servers have built-in trays or rails. Yet others require a special mounting tray or rails to fix the drive into the empty bay.

Airflow and cooling

HP LTO Ultrium drives require forced airflow, either from front to back or from back to front, that satisfies the following conditions:

HP LTO Ultrium 4 drives technical reference manual, volume 1: hardware integration 45

HP restricted

Page 46

• For full-height internal drives, the airflow at 35°C ambient air operation should be at least

6 cubic feet per minute (0.17 cubic meters per minute or 10.19 cubic meters per hour) through the product. At 40°C, it should be at least 8 cfm (0.23 m

These requirements and the operating temperature specification should keep the internal temperature around the media to less than 45°C and ensure reliable operation.

The airflow does not require filtering if the air contamination specifications are met. See “Climatics” in Chapter 4, “Environmental Specification” in Specifications, Volume 4 of the HP LTO Ultrium Technical Reference Manual.

CAUTION: Care must be taken that empty bays in the server have the appropriate blanking plates

installed so that airflow is maintained. Refer to your server documentation.

For details of how to measure the internal drive temperature, see “Measuring internal drive

temperatures” on page 16.

Power requirements

NOTE: SAS drives should be powered from the normal rear panel connector, not through the

power part of the SAS connector.

The following are the PSU requirements for FC, SCSI and SAS full-height drives:

Full-height drives

Server connections

You need a properly installed and configured SCSI or SAS host bus adapter (HBA) or a built-in SCSI or SAS controller on the server.

The SCSI drives are Ultra3 wide, SCAM-1 compliant SCSI devices designed to operate on a low voltage differential SCSI bus (LVDS). LVDS interfaces enable longer cable lengths compared with single ended SCSI and Ultra3 supports a maximum bus speed of 160 MB/s (as opposed to 80 MB/s with Ultra2 and 40 MB/s with single-ended SCSI). Therefore, we do not recommend installing the drive onto an Ultra2 or single-ended bus or onto a bus with other Ultra2 or single-ended devices, as this may restrict performance. Similarly, do not install the drive onto a narrow SCSI bus, as this will restrict performance.

FC Drives SCSI Drives SAS Drives

The SAS drives have a 3 GB SAS interface, and are designed to work with most SAS devices. The 3 GB SAS interface supports a maximum bus speed of 300 MB/s, as opposed to the 150 MB/s of the 1.5 GB SAS interface. Therefore, we do not recommend installing the drive onto a 1.5 GB bus as this may restrict performance.

For optimum performance, use a dedicated host bus adapter for the tape drive.

Do not connect to a RAID controller channel; these are for disk drives only. Consult your supplier for details.

For a SCSI internal drive, you will need:

• Ultra3 (160) or Ultra4 (320) SCSI host bus adapter or server’s embedded HBA

• LVDS-compliant SCSI ribbon cable with termination (normally supplied with the host bus adapter)

• A full-height 5¼-inch mounting bay

• Mounting hardware, if required

• Backup software that supports the tape drive

For a SAS internal drive, you will need:

• 3 GB SAS host bus adapter or server’s embedded HBA

• SAS-compliant cable

• Mounting hardware, if required

Fixing dimensions

The positions of fixing points are shown below.

The recommended screw length depends on the thickness of the rails or enclosure into which the drive is mounted:

Server or Rail Thickness Recommended Screw Length

> 1.5 mm ≤ 2.0mm M3 x 6.0mm

> 1.0 mm ≤ 1.5mm M3 x 6.0mm

Up to 40 MB/s Yes, but this is not recommended as it will severely restrict

performance. Do not connect to a narrow SCSI bus.

Up to 40 MB/s No. The drive will not work and you may damage the

drive or controller

≤ 1.0mm M3 x 5.0mm

All screws should be M3 threaded. Do not use spring washers.

The recommended mounting torque is 6.0 ±0.5 in-lbs (60–70 N/cm).

HP recommends 0.3 mm mounting clearance around all covers for isolation mounting movement.

Connecting the drive

Fibre Channel connector

For the location of the rear panel FC connector, see page 80.

The fibre channel drive is equipped with a native fibre channel interface consisting of two SFP duplex-LC fibre channel transceivers. The tape drive is capable of switched fabric attach or public loop.

Page 50

The rear connections of Fibre Link HP LTO Ultrium drives are as follows:

• ACI/ADI port (for libraries)

• Two SFP duplex-LC fibre connectors (only one may be loaded)

• Serial port (duplicate of the Serial Diagnostics Port on the front panel)

SCSI connector

For the location of the rear panel SCSI connector, see page 80.

The SCSI drive uses a straddle-mounted three-part SCSI peripheral connector. This incorporates a 68-pin high density SCSI connector, a 4-pin power connector and a 12-pin auxiliary connector.

The auxiliary connector is used for setting the SCSI address. The pins are as follows:

Pin Signal Description Pin Signal Description

1 SEL0- SCSI ID 0 (active low) 7 SEL3- SCSI ID 3 (active low)

2 GND Ground 8 GND Ground

To connect an internal drive:

1. Attach a spare power cable from the computer’s internal power supply to the power connector.

2. Attach a spare connector on the computer or HBA’s SCSI ribbon cable to the SCSI connector of

the drive.

3. If the drive is the last device on the SCSI chain, make sure that the SCSI cable is terminated

correctly.

Termination

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 marked ‘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. If the drive should be the only device on a bus, as is recommended, the terminator should be placed after the drive.

Termination power

With HP’s LTO Ultrium drives, termination power is provided and is switchable through pins 11 and 12 of the auxiliary connector. The supply is a 5V line via a fuse and diode/capacitor combination. In this way, the drive “tops up” the termination power voltage if the host supply is below 5V (due to cable length or bad host termination power).

SAS connector

For the location of the rear panel SAS connector, see page 77

The SAS drive is equipped with a 3 Gbps SAS plug connector as per SFF8482 [5.2.3.2]. A SAS drive is hot pluggable but the connector location is not as per SFF8482.

NOTE: Only power a SAS tape drive from the normal power connector, not through the power port

of the SAS connector, which is not connected.

The rear connections of an HP LTO4 SAS tape drive are as follows:

• ACI/ADI port (for libraries)

• Standard internal SAS plug connector

• Diagnostic Serial Port (contact HP for further details on this diagnostic port and its function)

Backup software

You need backup software that supports the HP LTO Ultrium drive within 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 and SAN configurations, you will need backup software that supports enterprise environments. As a general rule, native backup applications (such as NTBackup and tar) do not provide the required data streaming rate to get the full performance of your drive. For the latest list of backup packages that

Loading a cartridge

Unloading a cartridge

Use HP LTO Ultrium cartridges with your drive.

1. Insert the cartridge into the slot in front of the drive

with the white arrow uppermost and facing the drive door.

2. Apply gentle pressure on the rear of the cartridge

until the drive takes the cartridge and loads it.

The Ready LED flashes green while the drive performs its load sequence. When the cartridge is loaded, the Ready LED shows steady green.

Do not try to force the cartridge if it does not load properly. The drive will eject the cartridge after about 10 seconds so you can load it again.

1. Press the Eject button on the front panel.

During the unload sequence the READY LED flashes green. The drive completes any task it is currently performing, rewinds the tape and ejects the cartridge. Once the tape has rewound, the eject cycle will take less than 13 seconds.

2. Remove the cartridge and store it in its plastic case in

a cool, dry atmosphere.

Cleaning the drive

CAUTION: It is essential to use only LTO Ultrium Universal cleaning cartridges with HP LTO Ultrium

tape drives as other format cleaning cartridges will not load and run. Use of HP Universal cleaning cartridges will ensure your tape drive is fully protected. Do not use swabs or other means of cleaning the heads.

When the drive needs cleaning, the orange ‘Clean’ LED on the tape drive will flash. Only insert a cleaning cartridge into the tape drive when the LED flashes.

Internal drives in servers54

HP restricted

Page 55

The drive’s TapeAlert feature will send a message to your backup application when the tape heads need cleaning or a cleaning cartridge has expired.

LTO Ultrium Universal cleaning cartridges can be used up to 50 times.

To clean the heads, proceed as follows:

1. Insert a cleaning cartridge into the drive. The tape drive automatically loads the cartridge and

cleans the heads. If the cleaning cartridge ejects immediately, it has expired or it is not an LTO Ultrium Universal

cleaning cartridge (or is an older LTO Ultrium 1 cleaning cartridge). In this case, discard the cleaning cartridge and repeat the operation with a new one.

The cleaning cycle can take up to 3 minutes, during which the orange ‘ the green ‘Ready’ LED will flash. When it has finished, the drive ejects the cartridge.

2. Remove the cleaning cartridge from the drive.

Troubleshooting

Emergency unload

If the cartridge is still jammed, press the emergency reset button (see page 53). Wait for the drive to reset and get back to the loaded position. This may take up to 15 minutes. Again press and hold the Eject button for 10 seconds to perform an emergency unload.

General guidelines

If you experience problems when using the tape drive, you need to isolate the cause of the problem. For example, if you have just installed a new host bus adapter and your system will not start, the cause of the problem is likely to be the adapter.

When installing multiple items of hardware and software, we recommend that you install each in turn and restart the system each time. Similarly if you have already installed multiple devices and software and you experience problems, remove or uninstall each in turn to establish which one is causing the problem.

Remember that the system recognizes devices during boot-up. If you swap or connect a product when your system is running, you will need to reboot the system. Rebooting the system will reset devices and will often resolve problems. It is good practice to reboot every time you add a driver or install firmware.

Diagnosing the problem

The first step in problem-solving is establishing whether the problem lies with the cartridge, the drive, the host computer and its connections, or with the way the system is being operated.

For the physical specification of the drive, see Chapter 1, “Physical Specification” in Specifications, Volume 4 of the HP LTO Ultrium Technical Reference Manual.

If you are installing the tape drive on a UNIX system, refer to the UNIX Configuration Guide, Volume 5 of the HP LTO Ultrium Technical Reference Manual.

Identifying the drive

The model name is on the front panel and the product and serial numbers are on a label on the bottom of the drive.

Connecting the drive

SCSI connection

The rear panel connections on the external SCSI standalone drives consist of a mains power connector, two 68-pin very high density SCSI-3 connectors and a SCSI address switch. The drive should be connected to the server via a 68-pin, wide LVDS-rated cable using the SCSI-IN connection on the back of the drive. The standard, recommended configuration is a direct one-to-one SCSI connection between the tape drive and the host server so that the drive is the only device on the SCSI bus. You can daisy-chain two or more drives together, but to preserve performance you should only do this if the drives are on an Ultra320 SCSI bus. Do not daisy-chain more than two drives as this will degrade their individual performance.

Setting the SCSI ID

Each drive should have a unique SCSI ID. Set the ID using the SCSI address switch on the rear of the drive enclosure. Remember that a SCSI address of 7 is usually reserved for the host bus adapter.

Termination

Both ends of a SCSI bus must be terminated. As long as the drive is the last or only device on the SCSI bus, the drive enclosure automatically provides active termination when a cable is connected to the SCSI-IN connector. If there are other devices on the bus (which is not recommended), use the SCSI-OUT connector to connect to the next device in the chain, and make sure that the chain is terminated at the end with a multimode terminator.

If the drive is providing active termination, the green LED on the rear panel marked Act TERM will be lit (see page 63).

Termination power

With HP’s LTO Ultrium drives, termination power is always provided; you cannot switch it off. The supply is a 5V line via a fuse and diode/capacitor combination. In this way, the drive “tops up” the termination power voltage if the host supply is below 5V (due to cable length or bad host termination power).

SAS Connection

The rear panel connections of an external SAS standalone drive consist of a mains power connector and a Mini-SAS connector. The drive should be connected to the host server/expander with a good quality external SAS cable that is as short as possible. If you are attaching an SAS drive to a server, you will need a properly installed and configured SAS host bus adapter (HBA) or a built-in SAS controller on your server with a spare SAS port. For optimum performance your tape drive should only be connected to a 3 Gbps SAS host bus adapter or SAS controller, but the drive will also work with a 1.5 Gpbs SAS bus.

Moving drives

If there is a tape in the drive, unload it before powering down and moving the drive. When the drive is powered down, there is no physical lock on the tape reels. If you leave a tape threaded in the drive with the power off, the reels could rotate, causing a loop of tape to occur in the tape path. When the drive is next powered up, the tape could then fall off the guides and be damaged.

If for any reason you must move a drive with a tape threaded, move it slowly and carefully, making no sudden movements that could cause the reels to rotate.

Operating the drive

Switch on external drives using the power switch on the front panel, and then switch on the host computer.

The tape drive will run its hardware self-test, during which the ‘Ready’ LED flashes and all the other LEDs are off. On successful completion the ‘Ready’ LED is on.

If the self-test fails, the ‘Drive Error’ and ‘Tape Error’ LEDs flash, while the ‘Ready’ and ‘ are off. This continues until the drive is reset.

• If you have just installed the drive, check the installation for loose connections, reset the drive

and repeat the self-test.

• Try “Troubleshooting” on page 64 to determine what the problem is.

• If the fault condition persists, call for assistance.

Cleaning the drive

When the drive needs cleaning, the orange ‘Clean’ LED on the front of the tape drive will flash. Only insert a cleaning cartridge into the tape drive when the LED flashes.

NOTE: The drive’s TapeAlert feature will send a message to your backup application when the

tape heads need cleaning or a cleaning cartridge has expired.

Page 64

CAUTION: It is essential to use only LTO Ultrium Universal cleaning cartridges with HP LTO Ultrium

tape drives as other format cleaning cartridges will not load and run. Use of HP cleaning media will ensure your tape drive is fully protected. Do not use swabs or other means of cleaning the heads.

LTO Ultrium Universal cleaning cartridges can be used up to 50 times.

To clean the heads:

1. Insert a cleaning cartridge into the drive. The tape drive automatically loads the cartridge and

cleans the heads. If the cleaning cartridge ejects immediately, it has expired or it is not an LTO Ultrium Universal

cleaning cartridge (or is an older unsupported LTO Ultrium 1 cleaning cartridge). In this case, discard the cleaning cartridge and repeat the operation with a new one.

The cleaning cycle can take up to 3 minutes, during which the orange ‘ the green ‘Ready’ LED will flash. When it has finished, the drive ejects the cartridge.

2. Remove the cleaning cartridge from the drive.

Troubleshooting

Emergency unload

If the cartridge is still jammed, press the emergency reset button (see page 61). Wait for the drive to reset and get back to the loaded position. This may take up to 15 minutes. Again press and hold the Eject button for 10 seconds to perform an emergency unload.

General guidelines

If you experience problems when using the tape drive, you need to isolate the cause of the problem. For example, if you have just installed a new SCSI host bus adapter and your system will not start, the cause of the problem is likely to be the adapter.

External standalone drives64

HP restricted

Page 65

Problems with the host computer

Most modern SCSI host bus adapters locate and display attached devices when the system is booting up. If the device is not detected at this stage, there is probably a problem with the physical hardware: cables, termination, connections, power or the HBA itself.

If your drive is found on system boot up but cannot be found in the operating system, this is more likely to be a software problem.

Computer does not boot up

Possible Cause Potential Solution

You have connected the tape drive to an existing SCSI bus that has other devices connected to it and the SCSI address of the drive is identical to the address used by another device.

You have installed an additional SCSI host bus adapter and its resources are clashing with an existing adapter.

You have disconnected the power or SCSI cable from the computer’s boot disk during the drive installation process.

Computer boots, but does not recognize the drive

Possible Cause Potential Solution

The power or SCSI cable is not connected properly.

The SCSI bus is not terminated correctly. Remove the new host bus adapter and check the

The tape drive’s SCSI ID address is not unique.

The tape drive may have been switched on after the computer was booted up. The computer checks for SCSI devices only at power-on.

Problems with the drive and cartridge

Tape drive does not power up

Possible Cause Potential Solution

The power cable is not connected properly.

The self-test fails (Ready LED is off and the other LEDs are on solidly).

The application does not recognize the drive

Possible Cause Potential Solution

The application does not support the tape drive.

Some applications require drivers to be loaded.

Check the drive is installed properly. Refer to our World Wide Web site (www.hp.com/go/connect support HP LTO Ultrium tape drives. Load any service packs as necessary.

Check the correct HBA and tape drive drivers are installed. Consult the backup application’s installation notes for details.

The cartridge will not eject

Possible Cause Potential Solution

The cartridge is jammed in the drive, or the backup application cannot eject the cartridge.

This is most likely to be a communication problem between drive and system.

Check there is power to the drive.

Press and hold the Eject button for 10 seconds. Allow the drive up to 15 minutes to eject (this is the maximum rewind time of the cartridge.)

If the cartridge is still jammed, reset the drive (see page 61). Allow 15 minutes for the drive to return to the loaded position. Press and hold the Eject button for 10 seconds to eject the cartridge from the reset drive.

If the cartridge is still jammed, call for support.

The drive will not accept a cartridge

Possible Cause Potential Solution

The cartridge is not compatible with your tape drive.

Check you are using LTO Ultrium 2, 3 or 4 media. DLT cartridges are not compatible with LTO Ultrium drives.

Check the orientation of the cartridge when loading into the drive.

Note: LTO Ultrium 1 cartridges are not supported in HP LTO Ultrium 4

tape drives.

The cartridge has been damaged.

Check the cartridge case is not cracked or split.

Check the leader pin and cartridge teeth are not damaged. If they are, discard the cartridge.

If the drive will still not accept the cartridge, try a new or known good cartridge. If it loads, the original cartridge is faulty and should be discarded.

If the original cartridge is accepted in another tape drive, the original tape drive may be at fault. Check the SCSI connection and that the tape drive is recognized by the backup application.

The tape drive is faulty. Check the drive is powered on.

If the drive still will not accept the cartridge, there may be a problem with the drive’s cartridge memory. Call support.

6 Front panel and LEDs

There are three front panels for full-height HP LTO Ultrium 4 products:

• Default—see page 53

• Automation, for use when the drive is embedded in automation applications—see page 14

• A third front panel allowing drives to be used in 2U autoloaders where the front panel cannot

exceed the drive form factor in height and width—see page 14

The drive is not designed to operate without a front panel (even in automation applications). The front panel was designed to meet Section 508 accessibility guidelines.

Full details of the default front panel are given in the Operation topic within the User’s Guide.

LEDs (Fibre Channel drives only)

The rear panel has two LEDs, one each for Fibre Channel Port A and Port B.

Power-on self-test failure

If the Fibre Channel firmware encounters a Power-On Self-Test failure, the drive will not initialize the FC ports and so will not respond over the FC interface. The two FC port LEDs will flash together at 1 cycle/second until the drive is reset or power-cycled.

Port initialized

Once the self-test in complete, the FC Port LEDs indicate whether the respective ports have been initialized, in other words, whether successful speed negotiation and loop initialization/old port mode has occurred.

Fibre Channel addressing

The drive’s hard AL_PA can be configured in two ways:

• Jumpers connected to the address connector on the PCA

• An ACI Set Drive Configuration command or ADI Mode Select command

The value set using either of these two methods is the Loop ID, an 8-bit value which is translated by the drive into a 7-bit Arbitrated Loop Physical Address (AL_PA) according to Table 1:

Connectors

SCSI connector

HP LTO Ultrium 4 drives are Ultra 320 wide, SCAM-1 compliant SCSI devices designed to operate on a low voltage differential (LVD) SCSI bus. They use a 68-pin SCSI Ultra 3 LVD interface to communicate with a tape library or host computer system.

he SCSI connection is a straddle-mounted three-part SCSI peripheral connector. This incorporates a 68-pin high density SCSI connector, a 4-pin power connector and a 12-pin auxiliary connector. The stub length (SCSI IC to connector) is 22 mm average.

In a library, the SCSI and power connectors interface with appropriate cables connected to the library bulkhead. The SCSI cables may be installed in a daisy-chain configuration linking two or more LTO Ultrium tape drives within the library together on the same SCSI bus.

The auxiliary connector is used for setting the SCSI address.

Each device on the SCSI bus must have a unique SCSI ID set by the library or by the auxiliary connectors.

Fibre Channel connector

FC drives are equipped with two SFP duplex-LC short-wave 4 Gb/s fibre connectors. The drives are capable of switched fabric attach, public loop or private loop and operate at 4 Gb/s, 2 Gb/s or 1 Gb/s after auto-speed negotiation.

SAS connector

SAS drives are equipped with a standard internal SAS connector. HP LTO Ultrium 4 drives should only be powered from the normal power connector, not from the power port of the SAS connector, because this is not connected.

Automation Device/Interface (ADI) connector

The automation connector is a 10-pin JST PH surface-mount right-angle connector. This is mounted alongside the main interface. It can be mated with either crimped or insulation displacement connectors, as follows:

Crimped connectors

Housing: PHR-10 Contacts: SPH-002T-P0.5S (for AWG# 30-24 wire)

8 Modes of usage and optimizing performance

Modes of usage

HP LTO Ultrium tape drives and arrays can be used in different system configurations (SCSI and SAS drives can be directly attached to a VHD SCSI or SAS connector respectively on a server or fibre channel router). They can be used in a standalone (direct attach) or network environments (both Local Area Network and Storage Area Network).

To connect a SCSI drive or array to fibre channel you must purchase and install a supported fibre channel/SCSI router.

A SCSI tape drive or array should be connected to the VHD SCSI connector on the server or router. A SAS tape drive or array should be connected to the SAS connector on the server or router. Network users may need to take additional steps/to ensure that their system is configured for optimum performance. These are described in “Optimizing performance” on page 84.

Direct Attach

A SCSI tape array is directly attached to a single server via a SCSI link or a fibre channel/SCSI router.

Network Attach (LAN)

A SCSI or SAS tape array is directly attached to a network storage server that can be accessed by a number of clients or workstations. As with the direct attach model, the connection is via a SCSI or SAS link or fibre channel/SCSI router to the storage server.

Optimizing performance

Various factors can affect tape drive performance, particularly in a network environment or if the drive is not on a dedicated bus. If your tape drive is not performing as well as expected, consider the following points before contacting HP Support at www.hp.com/support

Modes of usage and optimizing performance84

HP restricted

Page 85

Dedicated SCSI bus

For optimum performance, we recommend that the tape drive is the only device on the SCSI bus. If it is not, ensure other devices are LVD-compliant. If they are single-ended, the bus will switch to single-ended mode with a lower transfer speed. There will also be restrictions on cable length.

System performance

Drives can write data at 120 MB/s (native) or 240 MB/s (2:1 compression). However, to get this performance it is essential that your whole system can deliver this performance.

Typical areas where bottlenecks can occur are:

• Disk system (a single hard disk drive will not be able to deliver 240 MB/s transfer rates).

• Some file systems are able to transfer data faster than others.

• The type of data being backed up can affect backup performance (for example, file sizes and

compressibility).

• Some backup software performs better than others.

To improve performance you may like to consider a RAIDed disk solution with a large number of physical hard disks.

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.

Data transfer rate

Adaptive Tape Speed (ATS) enables the drive to “stream” data at variable tape speed, which means that it maintains a continuous data flow to tape even when the transfer speed varies. This is automatically managed by the drive to keep the drive running at best performance. When using LTO Ultrium 4 cartridges, the ATS range is 40 to 120 MB/s (native), so, if possible data transfer should remain within this range. In most cases, the backup application will provide details of the average time taken at the end of the backup.

NOTE: For optimum performance always use Ultrium 4 1600 GB cartridges.

Performance checklist

The following list summarizes factors that can affect performance. They provide guideline only of areas that may need further investigation. They do not attempt to explain how to configure individual systems. For a more detailed discussion, including information about tools that allow you to test performance, refer to our white papers on www.hp.com. the Information Library.)

• Is the tape drive reading and writing data at the correct speed?

• Is the source system (hard disk) transferring data at the correct speed?

• Is the backup application writing buffers at the correct speed? You may need to tune the transfer,

buffer and block size settings to optimize the speed that the application writes data to the tape drive. HP LTO Ultrium drives have an internal buffer of 128 MB.

• Is the operating system tuned for performance? You may need to adjust the data transfer packet

size.

• If you are using a SCSI drive or array in a SAN environment, are you are using one of the

recommended fibre channel/SCSI routers?

• Are user applications, such as Exchange or database servers, optimized for backup

performance?

• Are there other factors that could be affecting performance, such as interference or fibre channel

infrastructure?

Choosing cartridges

HP recommends HP LTO-4 Ultrium 1600 GB (2:1 compression) cartridges.

HP LTO Ultrium drives will also support other lower capacity HP and non-HP LTO Ultrium cartridges but the performance of your drive may be restricted. Data transfer rates will be slower on LTO Ultrium 3 800 GB cartridges compared to LTO Ultrium 4 1600 GB cartridges. Do not use HP DLTIIItape or DLTIVtape cartridges. The size and shape of LTO Ultrium media is very similar to that of DLT cartridges in order to make it easy for automation/library vendors to integrate LTO Ultrium into existing DLT libraries. Compatible media can be recognized by the LTO Ultrium logo, which is the same as the logo on the front of your drive.

NOTE: HP LTO Ultrium 4 tape drives are not compatible with LTO Ultrium 1 media, which will be

rejected as unsupported. The Tape Error LED will light.

HP recommends HP LTO Ultrium cartridges as follows:

• LTO Ultrium 1600 GB RW for multiple reading and writing

• LTO Ultrium 1600 GB WORM cartridges. WORM (

against accidental or malicious alteration of data on the tape cartridge. You can append data to a WORM data cartridge to use the full capacity but not erase or overwrite existing data. WORM data cartridges have a distinctive, two-tone cartridge color. To check whether your backup or archive software application supports WORM cartridges, refer to the web site:

www.hp.com/go/connect.

Write-Once, Read-Many) cartridges guard

Labeling cartridges

Write-protecting cartridges

If you want to protect the data on a cartridge from being altered or overwritten, you can write-protect the cartridge. Do this before you insert the cartridge. If you slide the write-protect tab after the cartridge is inserted in the drive, the change will not take effect until the cartridge is removed and reinserted, and you could damage the tape drive.

HP LTO Ultrium 4 drives technical reference manual, volume 1: hardware integration 87

The label and write-protect switch are on the rear face of the cartridge, as illustrated.

Never use non-standard labels, and never stick anything to the cartridge other than in the label area.

HP restricted

Page 88

CAUTION: Write-protection will not prevent a cartridge being erased by bulk-erasure or

degaussing. Do not bulk erase LTO Ultrium format cartridges. This will destroy pre-recorded servo information and render the cartridge unusable.

Cartridge life

Under optimum environmental conditions, HP LTO Ultrium cartridges are currently specified to 1,000,000 passes over any part of the tape. In operational terms, this can be translated to about 2000 full backup or restore operations. However, it is recommended that cartridges are used for no more than 260 full backup operations and the cartridge warranty is based on this figure. Under severe environmental conditions, particularly where the tape drive is used at low humidity or if certain areas of the tape are accessed frequently, the number of backup operations should be limited even further.

Caring for cartridges

To write-protect a cartridge, slide the write-protect tab by the label area on the rear face of the cartridge to close the hole.

Note the padlock on the tab that indicates that the cartridge is protected.

To write-enable a cartridge, slide the write-protect tab back so that the hole is open, before loading the cartridge into the drive.

Avoiding condensation

Condensation can be a problem for tape drives and cartridges. To minimize the chance of condensation, stay within the specifications for using and storing cartridges above and observe the following guidelines:

• Position the drive where the temperature is relatively stable—away from open windows, heat

sources and doors.

• Avoid leaving cartridges in severe temperature conditions, for example, in a car standing in

bright sunlight.

• Avoid transferring data (reading from and writing to cartridges) when the temperature is

changing by more than 10°C (18°F) per hour.

• If you bring a cold tape drive or tape cartridge into a warm room, allow time for it to warm to

room temperature before using it. For example, if you have moved the drive from a cold car to a warm room, allow time for the drive to reach room temperature (up to 24 hours if the temperature change is extreme).

Conditions in use

Only use LTO Ultrium cartridges in temperatures in the tape drive’s operating range from 10°C to 40°C (50°F to 104°F) and 20 to 80% relative humidity (non-condensing). If you expose cartridges

Cartridges88

HP restricted

Page 89

to temperatures outside the operating limits, stabilize them before you use them. To do this, leave the cartridges in the operating environment for 24 hours.

Conditions in storage

LTO Ultrium cartridges will preserve the integrity of stored data for at least 30 years if proper storage conditions are observed.

• For short-term storage, keep cartridges at temperatures between 16°C and 32°C (61°F and

90°F) with a relative humidity between 20% and 80%.

• For long-term archival storage, keep cartridges between 5°C and 23°C (41°F and 73°F) with a

relative humidity between 10% and 50%. Wet bulb temperature should not exceed 26°C (78°F).

• Always keep the cartridges in a clean environment.

• Always store cartridges in their plastic cases on their side when not in use.

Maximizing tape life

• Do not touch the tape surface.

• Do not attempt to clean the tape path or tape guides inside the cartridge.

• Do not leave cartridges in excessively dry or humid conditions.

• Do not leave cartridges in direct sunlight or in places where magnetic fields are present (for

example, under telephones, next to monitors or near transformers).

• Do not drop cartridges or handle them roughly.

• Stick labels onto the label area only.

LTO Cartridge Memory

Linear Tape Open—Cartridge Memory (LTO-CM) is EEPROM memory that is embedded in every LTO Ultrium tape cartridge. It is non-volatile and is contactless in that it is read by inductive coupling rather than electrical contact.

An access method has been defined to allow hosts to use this free space using Write Attribute and Read Attribute commands. For information on these commands, see Chapter 4 of The SCSI Interface, Volume 3 of this HP LTO Ultrium Technical Reference Manual.

For details of use of LTO-CM in library applications, see “Using Cartridge Memory (LTO-CM)” on

page 30.

LTO Cartridge Memory issues

The LTO Cartridge Memory stores identification and usage information such as the number of times the cartridge has been loaded, when it was last cleaned, and error logs. In the unlikely event of the Cartridge Memory becoming damaged, you may experience difficulty with the cartridge.

Use the following table to resolve LTO Cartridge Memory problems:

Problem Cause Solution

A new data cartridge that is write-enabled is rejected by the drive.

A new data cartridge that is write-protected is rejected in several known good drives.

A cartridge that has data written to it and is write-enabled is rejected by the drive.

A cartridge that has data written to it and is write-protected restores very slowly.

LTO Cartridge Memory has failed or is damaged.

LTO Cartridge Memory has failed and the drive has found no data to recover.

LTO Cartridge Memory has failed or is damaged.

LTO Cartridge Memory has failed and the drive cannot use the tape directory information to recover the data.

Replace the data cartridge.

The data can still be recovered. Contact the tape library supplier for more information. After data recovery, replace the cartridge.

The data can still be recovered but may take longer than normal.
