before calling for service or support

Before calling for service or support, check that:

Check that your HP Surestore Tape Drive is installed correctly Check the printed Getting Started Guide and the troubleshooting advice in this online User's Guide

obtaining service

Please use the Customer Service Form to collect the details that our Customer Service Representative will need to help solve your problem.

During the warranty period: HP provides a free telephone support service during the warranty period. Contact your local HP dealer or the appropriate HP technical support contact for your area, by selecting the region required from the navigational buttons in the left hand pane. Obtain the telephone number from the list of countries supplied. You will be connected to a responsive team waiting to help you.

After the warranty period: If you require support after your warranty has expired, you can receive support for a fee through the same telephone numbers. The fee is charged on a per incident basis. Alternatively, you can contact your local HP dealer who will be able to advise you and arrange for service.

The telephone service agent will verify that the unit is faulty and will make sure that a replacement unit is sent to you within 24 hours. When you receive the replacement unit, remove it from the packaging and use the packaging material for returning the faulty unit. All shipment costs are prepaid by HP.

When returning the drive to HP, any damage caused as a result of inadequate packaging is your responsibility. Use the original packing materials whenever possible.

warranty conditions

This warranty gives you specific legal rights. You may also have other rights which vary according to where you are located.

Hewlett-Packard warrants its Surestore tape drives against defects in materials and workmanship for a period of three years, either from the date of delivery or, where the purchase price includes installation by Hewlett-Packard, from the date of installation. If a new HP Surestore tape drive is purchased as a component of an HP computer system, the tape drive warranty is automatically upgraded to the system warranty.

You are entitled to:

automatic three-year, next day unit exchange system matching warranty on HP systems (internal and external units), when purchased as a component of that system free technical call center assistance during the product support life (does not include telephone call cost)

Further information is available via the web at: www.hp.com/support/tapewarranty

During the first three years, the 24-hour Express Exchange program (not available in all countries) allows you to receive a replacement unit by next-day delivery upon verification of a faulty tape drive. Hewlett-Packard will, at its option, either repair or replace products that prove to be defective. Should Hewlett-Packard be unable to repair or replace the product within a reasonable period of time, a refund of the purchase price may be given upon return of the product.

If you choose not to use Express Exchange, your HP Surestore tape drive must be serviced by one of the authorized repair depots within the country in which it was originally purchased. You must prepay shipping charges (together with all duty and taxes) for products returned for service. Except for products returned to you from another country, Hewlett-Packard will pay for return of products to you. If the drive is repaired by an authorized dealer, you will need to negotiate the method and cost of returning the drive with the dealer.

exclusions

The warranty on your HP SureStore tape drive does not apply to defects resulting from:

improper or inadequate maintenance by the customer Customer-supplied software or interfaces Unauthorized modification or misuse Use of unsupported media Operation outside the environmental specifications for the product Improper site preparation and maintenance

pre-installation check list

Before you install your HP Surestore DLT1 tape drive:

1. Check that your computer meets the requirements for installation.

2. Make a note of the model name, product number, and serial number of your

tape drive.

3. Collect information about the SCSI configuration of your computer and any

other devices attached to it and decide how you are going to configure the drive on the SCSI bus. If you are installing on a Windows NT 4, Windows 2000, or Novell NetWare system, you can use the HP Library & TapeTools

software. If you are not familiar with how to configure a SCSI bus, you may also want to read the

SCSI Background information provided in this guide.

4. Select a free bay for an internal or a removable drive

or Select a site for an external drive.

installation

The Getting Started guide provides detailed installation instructions.

Click below for a PDF version of the appropriate guide:

● HP Surestore DLT1 internal drives: Getting Started guide

● HP Surestore DLT1 external drives: Getting Started guide

You need a copy of Adobe Acrobat Reader to read the PDF files. If you do not have a copy of this software, you can link to Adobe's web site to download a free

copy.

how to identify your model

For internal drives, the model name is on the front panel and the product and serial numbers are on a label on the top of the drive.

For external drives, the model name is on the front panel and the product and serial numbers are on a label on the bottom of the drive.

computer and backup software

The HP Surestore DLT1 tape drive has the following hardware and software requirements:

computer systems

If you are installing the tape drive on a UNIX system, refer to the UNIX instructions for further information about the systems supported and installation instructions.

For the latest list of operating systems that support HP Surestore DLT1 drives, please consult our World Wide Web site (www.hp.com/go/connect).

HP Surestore DLT1 tape drives are Ultra SCSI-2 wide devices designed to operate on a low voltage differential SCSI bus (LVDS) with a burst transfer rate of 40 MB/sec. Using the drive on a single-ended (SE) SCSI bus restricts performance. Do not use on the same bus as other single-ended devices as this will switch the LVDS host adapter into single-ended mode and restrict performance. We recommend that a dedicated host bus adapter is used for the tape drive. A suitable adapter is available from HP as an accessory (see Ordering

Information).

Your computer must have a properly installed and configured SCSI host adapter or a SCSI controller on the motherboard (SCSI-2 or SCSI-3 compliant) with driver software that supports the HP Surestore DLT1 drive. Check the server documentation for the specification of any built-in SCSI channels. Do not connect to a RAID controller channel; these are for disk drives only. Consult your supplier for details.

For an internal drive, you will need:

● A wide, Ultra SCSI-2 LVDS or SE SCSI bus

● LVDS-compliant SCSI ribbon cable with termination (normally supplied with

the host bus adapter)

● Available 5¼-inch, full-height mounting bay (or two adjacent, half-height

bays)

● Mounting hardware, if required

● Backup software that supports the tape drive

For external drives, the cable provided with HP Surestore DLT1 tape drives will attach to a computer with a wide LVDS SCSI connector (68 pins). Connecting the drive to an SE SCSI connector or a narrow SCSI host bus adapter will restrict performance. HP recommends that a dedicated host bus adapter is used for the tape drive. If your server or host bus adapter is equipped with a very high density (VHD) wide SCSI connector, you will need to order a High-End Tape Connect Kit (adapter with VHD-to-HD cable) or 68-pin VHD-to-HD cable. (See

Ordering

Information.)

backup software

You need backup software that supports the HP Surestore DLT1 drive. A TapeWare CD-ROM containing backup software by Yosemite Technologies is supplied with your tape drive.

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 HP Surestore DLT1 drive. We recommend using a backup application which provides better memory management as well as other useful features, such as TapeAlert. HP, Computer Associates, Veritas and Legato all provide suitable products that have been tested with HP Surestore DLT1 drives. For the latest list of backup packages that support HP Surestore DLT1 drives, please consult our World Wide Web site (www.hp.com/go/connect).

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 number, so check the table below for the appropriate reference.

front panel lights

The front panel of your HP Surestore DLT1 tape drive has three lights (LEDs) as shown below.

Write Protected (first light)

This LED indicates if a cartridge is writeprotected.

On, steady: The DLTtape cartridge is

write-protected.

Off: The DLTtape cartridge is

write-enabled.

Ready (second light)

This LED indicates when a cartridge is loaded.

On, steady: The DLTtape cartridge is

loaded and ready to use. On, flashing: The tape is in motion. Off: No cartridge is loaded.

Caution (third light)

This LED indicates when a cleaning tape should be used. See also "Cleaning".

On, steady: A calibration failure or hard

read/write error occurred. Try cleaning the drive with a tape approved for use in the DLT1 drive.

If after cleaning, this indicator is illuminated again when you load a DLTtape cartridge: it is probable that the DLTtape cartridge is causing problems. Try a new DLTtape cartridge. If this condition persists with other cartridges, use HP

Library and Tape Tools to

help you diagnose the problem.

Off: Cleaning is complete or

not needed.

All three LEDS

This indicates the status of the Power On Self Test (POST).

On, steady: POST is starting.

On, flashing: A POST error has occurred. For more information, see

Troubleshooting.

Note: LEDs during firmware update operation. See also Firmware Updates.

● During the firmware update process DO NOT RESET OR POWER CYCLE

THE DRIVE.

● When the drive is in firmware update mode, the Write Protected and Ready

LEDS flash.

● If a corrupt or incompatible image is downloaded for a firmware update, the

Ready and Write Protected LEDs do not flash. The drive resets and leaves the code update cartridge loaded to indicate that the code update was not successful.

● If a valid image is downloaded the Ready and Write Protected LEDs will flash

alternately during the update process. The code update cartridge is ejected on successful completion.

1. Insert the cartridge into the slot in front of the drive, oriented as shown above.

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

cartridge and loads it.

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

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.

Note: When you insert a new, unformatted cartridge into your HP Surestore DLT1 tape drive, the loading sequence takes longer because the drive is writing reference tracks on the tape.

to unload a cartridge

Internal drives

External drives

1. Press the Eject button on the front panel or use your backup software. During the unload sequence the Ready light flashes. The drive completes any task it is currently performing, winds the tape to the beginning, and ejects the cartridge. The eject cycle will take up to two minutes.

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

to label a cartridge

Use only DLTtape IV cartridges with your drive. Ensure that only one label is located in the label area of the cartridge. Never use non-standard labels, and never stick anything to the cartridge.

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

to write-protect a cartridge

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 by sliding the write-protect switch on the front of the cartridge.

Caution: Write-protection will not prevent a cartridge being erased by bulk-

erasure or degaussing.

To write-protect a cartridge, slide the write-protect switch to the left.

Note a small orange rectangle is visible indicating that the cartridge is protected.

To write-enable a cartridge, slide the the write-protect switch to the right.

choosing cartridges

Only rely on the best media to protect your valuable data. Thanks to HP's rigorous testing programs, HP Surestore DLT1 data and cleaning cartridges are the safest investment you can make.

HP DLTtape IV cartridges are designed to meet the exacting mechanical, environmental and durability specifications of data storage applications.

Order online at: www.hp.com/go/storagemedia.

Important: You must use only DLT1 cleaning cartridges with HP Surestore DLT1

tape drives. Be aware that cleaning cartridges that do not specify DLT1 on the cartridge may be accepted by the drive but will not clean the drive. Use only DLT1 cleaning cartridges.

Your HP Surestore DLT1 tape drive uses only DLTtape IV cartridges. Your DLT1 tape drive can read but not write DLTtape cartridges that use the DLT4000 format.

Make sure all cartridges that you want to use for writing are either unformatted or have been formatted with your DLT1 tape drive before loading them. If you want to reuse cartridges that have been formatted by a drive other than DLT1, use a magnetic bulk eraser to prepare the cartridges for use with your DLT1 tape drive.

caring for cartridges

Under optimum environmental conditions, Hewlett-Packard DLTtape IV 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. Under severe environmental conditions, particularly where the tape drive is used at very low humidity or if certain areas of the tape are accessed frequently, the number of backup operations should be limited even further.

Caution: Ensure that only one label is located in the label area of the cartridge.

Never use non-standard labels and never stick anything to the cartridge.

using cartridges

Only use DLTtape IV cartridges in temperatures in the tape drive's operating range from 10C to 40C (50°F to 104°F) and 20 to 80% relative humidity (noncondensing). If you expose cartridges 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.

storing cartridges

Store cartridges at temperatures between 16°C and 32°C (60°F and 90°F ) with a relative humidity between 20% and 80%.

Always keep the cartridges in a dust-free environment. Always store cartridges in their plastic cases 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 cartridge tapes in excessively dry or humid conditions. Do not leave cartridges in direct sunlight or near sources of heat 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. Do not locate more than one label onto cartridges; extra labels can cause the cartridges to jam in the tape drive. Place identification labels only in the slide-in slot on the front of the cartridge. Never use any type of adhesive labels on your DLTtape cartridge.

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:

1. Position the drive where the temperature is relatively stable -- away from open windows, heat sources and doors.

2. Avoid leaving cartridges in severe temperature conditions, for example, in a car standing in bright sunlight.

3. Avoid transferring data (reading from and writing to cartridges) when the temperature is changing by more than 10°C (18°F) per hour.

4. 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).

cleaning strategy cleaning cartridge cleaning the tape heads on a drive

cleaning strategy

HP Surestore DLT1 drives have been developed to have a minimal cleaning requirement. The Caution LED on the tape drive will be on when the drive needs cleaning. However, it is good practice that the drive is cleaned once every two weeks to ensure optimal performance.

IMPORTANT: It is essential to use only DLT1 cleaning cartridges with HP

Surestore DLT1 tape drives. Cleaning cartridges from other media manufacturers will not be accepted by the drive. Use of HP cleaning media will ensure your tape drive is fully protected.

cleaning cartridge

You must use only DLT1 cleaning cartridges to clean the tape heads. A cleaning cartridge is supplied with each tape drive.

Do not use swabs or other means of cleaning the heads. The cleaning cartridge uses a special tape to clean the tape heads.

A cleaning cartridge can be used up to 20 times. The cleaning cartridge includes a label with 20 small boxes printed on it. Always place a check mark in a box each time you use the cartridge to clean the drive. Replace the cleaning cartridge when all the boxes are checked.

Be aware that cleaning cartridges that do not specify DLT1 on the cartridge will be accepted by the drive but will not clean the drive. Use only DLT1 cleaning cartridges (see also

Ordering Information).

cleaning the tape heads on a drive

The drive's TapeAlert feature sends a message to your backup application when the tape heads need cleaning and the Caution LED illuminates. To clean the tape heads:

1. Insert a DLT1 cleaning cartridge into the drive. The tape drive automatically loads the cartridge and cleans the heads.

Note: If you insert another type of cleaning cartridge, the Caution LED turns off. Ensure that cleaning is performed only with DLT1 cleaning cartridges.

During the cleaning cycle the Caution LED flashes. At the end of the cleaning cycle, the Caution LED turns off to indicate that you should remove the cleaning cartridge. The cleaning cycle can take several minutes.

2. Remove the cleaning cartridge from the drive. If the Caution LED is illuminated when you insert a DLTtape cartridge

immediately after cleaning, try a new DLTtape cartridge. If this condition persists with other cartridges, use HP Library and Tape Tools to help you

diagnose the problem.

summary

HP Library & Tape Tools diagnostic utility

The HP Library & Tape Tools software provides a number of utilities for getting information about your tape drive and troubleshooting problems. It includes the following functionality:

Installation help and advice to help you install your product and operate it correctly A Discovery utility to find out what devices are attached to your SCSI bus

An Identity utility to find out detailed information about individual devices, for example the firmware version.

Tests to check that your drive is operating correctly.

A Firmware Update Utility that helps you find update files for

your tape drive and performs the update

A Support Ticket that generates detailed troubleshooting information for support calls (if you are connected to the Internet, you will be able to e-mail this information directly to your Support Center)

Comprehensive Help that is topic sensitive, should you need additional information for the screen currently displayed

Updates and the latest versions of this software are available from our World Wide Web site: www.hp.com/support/tapetools

installing HP Library & Tape Tools

You can install HP Library & Tape Tools from the web site:

www.hp.com/support/tapetools. The tool is distributed without firmware and

firmware files are downloaded separately. Installation is simply a question of selecting the required option and following the instructions on the screen.

using HP Library & Tape Tools

HP Library and Tape Tools checks for the presence of a SCSI controller and its driver software and identifies the SCSI IDs of existing SCSI devices. You can then select the required device from the device list and run one of the diagnostic utilities for that device by selecting the appropriate icon: Identity, Firmware, Test or Support.

For ease of use, comprehensive online help is built into the software.

compatibility

There are HP Library & Tape Tools versions for:

Windows NT 4.0 (workstation and server)

Windows 2000 (professional and server)

Novell NetWare 5 or 5.1

firmware updates

You can update the firmware in HP Surestore DLT1 tape drives either by downloading over the SCSI bus or by loading a firmware update cartridge.

Caution: DO NOT RESET OR POWER CYCLE THE DRIVE during firmware

update. Doing so can damage the drive's controller hardware.

using HP Library & Tape Tools to update firmware

Use HP Library & Tape Tools to download via SCSI. Any tape in the drive will be ejected automatically before update. The Write Protected and Ready LEDs flash at the same time during firmware update for about two to three minutes.

Note: If a corrupt or incompatible image is downloaded for firmware update then the Write Protected and Ready LEDs do not flash. The drive resets and leaves the code update cartridge loaded to indicate that the code update was not successful.

using a firmware update cartridge

Firmware update tapes are only available from HP. Refer to the Hewlett-Packard Support web site for update information (www.hp.com/support/dlt1).

To update the firmware from tape:

1. Locate the firmware update cartridge.

2. Remove all DLTtape cartridges from your DLT1 drive.

3. Press and hold the Eject button on your DLT1 drive's front panel until all

three LEDS illuminate (6 seconds) and continue to hold down until the lights go off (4 seconds). Release the Eject button.

4. Press and hold the Eject button again (4 seconds) until the Write Protected and Ready LEDs flash, then release the Eject button. The drive is now in firmware update mode. If you decide not to perform a firmware update at this point, no action is necessary. The drive returns to its normal operational state after 30-45 seconds of inactivity. If the drive does not go into the update mode, refer to the troubleshooting information on update mode.

5. Insert the code update cartridge into the drive. The drive temporarily turns off the Write Protected and Ready LEDS while it reads the cartridge and verifies that the firmware image file is valid. This process may take several minutes to complete.

❍ If the drive's code is up-to-date, the drive cancels firmware update

mode, and the process is complete.

❍ If the drive's code is not up-to-date, the drive reads the code image

file from the cartridge. The Write Protected and Ready LEDs flash at the same time during the update process which typically takes two to three minutes.

When the drive finishes reading the code image file from the update cartridge, the drive rewinds the cartridge to the beginning, resets, and performs a Power-On Self-Test (POST). The drive then ensures that the code image file is valid. If so, it updates the controller's flash EEPROM. The Write Protected and Ready LEDs flash at the same time during theupdate process.

6. The drive ejects the code update cartridge. Your DLT1 drive is now ready to use with the new code.

Note: If the drive does not eject the code update cartridge, the firmware update failed. For troubleshooting information, refer to

code update failed.

TapeAlert

Tape storage systems have a vital role to play in backing up essential data safely and securely. Yet until now, there has been no reliable way to identify errors and potential problems that may compromise their effectiveness or reliability.

Thanks to a new industry standard developed by Hewlett-Packard, however, that situation has changed. TapeAlert is a tape drive status monitoring and messaging utility that makes it easy to detect problems which could have an impact on backup quality. From the use of worn-out tapes to defects in the drive hardware TapeAlert provides easy-to-understand warnings of errors as they arise, and suggests a course of action to remedy the problem.

To take advantage of TapeAlert, you need:

● TapeAlert-compatible tape drives

● TapeAlert-compatible backup software

Network administrators will also find it extremely valuable to have TapeAlert for OpenView, which extends the benefits of TapeAlert across the network.

how it works

TapeAlert compatible tape drives - such as the latest DLT1 drives from HewlettPackard - are delivered with TapeAlert features built in as standard. The internal TapeAlert firmware constantly monitors the drive hardware and the media, checking for errors and potential difficulties. Any problems identified are flagged on a new SCSI log page, where 64 bytes have been reserved for use by TapeAlert.

After a backup has been completed, the TapeAlert-compatible backup application will automatically read the drive's TapeAlert SCSI log page to check for any problems. If an error is flagged, the backup software displays a clear warning message on the user's screen, and adds the TapeAlert messages to its logs. These messages are standard across all applications that support TapeAlert, and are designed to give clear explanation of the problem and suggested resolution. For example, a user attempting to backup onto a worn-out tape would encounter the message:

WARNING: The tape cartridge has reached the end of its useful life:

1. Copy and data you need to another tape

2. Discard the old tape

Errors Monitored

TapeAlert currently checks for errors occurring in the following main categories:

● Drive recoverable read problems

● Drive recoverable write problems

● Drive unrecoverable read problems

● Drive unrecoverable write problems

● Drive hardware defects

● Worn-out media

● Expired cleaning tapes

● Wrong media used

● Abnormal error conditions

TapeAlert for OpenView

TapeAlert for OpenView allows you to bring all TapeAlert-compatible tape drives on the network under the control of the network administrator. It integrates all the features and functions of TapeAlert into HP's network management utility, OpenView for Windows. As a result, tape drives can now be monitored and controlled remotely in the same way as other network elements such as disk drives and printers.

With TapeAlert for OpenView installed, error messages flagged by tape drives are passed to the backup applications in the usual way. The software then forwards the information to the network management console through the server's SNMP interface.

An OpenView alarm is then activated on the management console, alerting the network manager to the tape drives problem. The icon for the relevant server will change color, with the color indicating the severity of the alarm as follows:

RED

Critical

YELLOW

Warning

BLUE

Information

TapeAlert for OpenView also provides a graphical view of the tape drives on the selected server. Detailed configuration information is shown, together with a history of previous errors recorded.

For each alarm, TapeAlert provides a brief description of the error, together with the date and time of occurrence and an indication of severity. By clicking on the "More Info" button, it is possible to drill down to details such as the device and media involved, and suggestions for correcting the problem. For consistency and convenience, the error messages are identical to those displayed locally by TapeAlert.

As a result, it is easy for network managers to identify the source of problems occurring on any TapeAlert-enabled drive on the network.

a new standard

TapeAlert has been developed by Hewlett-Packard as a proposed new standard tape drive management. All new tape drives from Hewlett-Packard will be fully compatible with TapeAlert, and many major manufacturers and software companies are expected to adopt the standard. Software companies adopting the standard currently include:

● Computer Associates Software

● Seagate Software

● Stac

● Legato

● Novastor

The TapeAlert standard has been designed to allow easy integration into backup applications from any software vendor. Applications which comply fully with the requirements for TapeAlert will be awarded the use of the TapeAlert logo.

Designed for the Future

TapeAlert is an advanced technological standard which provides a comprehensive range of state-of-the-art features and functions. However, it has also been designed to allow considerable expansion and development in the future, as new possibilities and opportunities open up.

summary

Reliable, high-quality backups are essential to safeguard the vast amount of data stored on computer systems today. TapeAlert is an innovative standard that enhances reliability by monitoring tape drives and associated media during backup procedures.

Offering clear warnings of problems as they arise, TapeAlert allows users and network managers to eliminate unnecessary errors and ensure that data integrity and security is never compromised. Already gaining substantial support across the industry, TapeAlert is set to become the established standard for tape drive management.

help diagnosing the problem

If you experience problems using your tape drive after installation, use HP Library

& Tape Tools to help you diagnose the problem. HP Library & Tape Tools is

provided free of charge and is invaluable for solving problems with both the SCSI bus and its attached devices. It will help resolve SCSI ID numbers and also run some tests that may help you isolate problems.

You will also find troubleshooting information on the HP Support web site.

The HP Support web site contains links to:

● www.hp.com/support/dlt1 takes you to HP’s Customer Care web site for a

wide range of up-to-date information about your product

● www.hp.com/cpso-support/guide/psd/cscinfo.htm takes you to HP's

worldwide call center numbers

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.

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.

troubleshooting

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. If none of the following advice helps you solve the problem, refer to our World Wide Web Customer Care pages on

www.hp.com/support/dlt1 or call for assistance.

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. Refer to the SCSI topic for a detailed discussion of SCSI

IDs, termination and cabling.

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 your HP Surestore DLT1 drive is identical to the address used by another device.

Make sure that each device on the SCSI bus has a unique ID. We recommend that the HP Surestore DLT1 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.

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

Remove the new host bus adapter and check the server documentation

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

Check that the cables to all devices are firmly connected.

computer boots, but does not recognize the tape drive

Possible cause Potential solution

The power or SCSI cable is not connected properly.

Check that the cables to the tape drive are firmly connected. Ensure that the SCSI cable is LVDS-compliant and that it does not have any bent pins. Replace, if necessary. (See “Ordering Information”.)

The SCSI bus may not be terminated correctly.

1. If your HP Surestore DLT1 drive is the last or only device on the SCSI bus, make sure the device is properly terminated.

2. If your HP Surestore DLT1 drive is not the last or only device on the SCSI bus, check all SCSI cable connections and make sure the last device on the SCSI bus is terminated.

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

Identify the SCSI IDs of existing SCSI devices by using HP Library & Tape Tools.

Change the drive's SCSI ID. Shut down and turn off the host server or workstation; turn off the desktop drive. Change the drive's SCSI ID. Turn on the host server or workstation and desktop drive.

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

Switch on the tape drive, then switch the computer off and then on again.

The SCSI adapter may be incorrectly configured.

Check the SCSI host adapter configuration. Refer to the SCSI host adapter manuals for instructions.

The SCSI cable may be loose. Check both ends of the SCSI cable, both

for the desktop and internal drives.

The SCSI terminator might be loose or missing.

1. Make sure the terminator is properly seated on the open SCSI connector on the rear panel of the desktop drive or on the last device on the SCSI bus.

2. Make sure an LVD or SE terminator is in place on the end of the SCSI ribbon cable for the internal drive.

The SCSI terminator might not be at the end of the SCSI bus or more than two terminators might be present on the SCSI bus.

Make sure the terminators are placed only at each end of the SCSI bus--one at the host adapter and one on the last device on the bus, both internal and external.

The SCSI host adapter might be in a defective expansion slot.

Move the SCSI host adapter to a different expansion slot.

The SCSI bus might be too long. Make sure the total length of the SCSI bus

does not exceed the ANSI SCSI standard of 3 meters (10 feet) for an SE bus, 12 meters (40 feet) for an LVD SCSI bus with multiple devices, or 25 meters (82 feet) for an LVD SCSI bus with a single device.

problems with the drive

tape drive does not power up

Possible cause Potential solution

The power cable is not connected properly.

Check that the cables to the tape drive are firmly connected.

Make sure that the power cable is firmly connected.

● For internal drives, try another

power connector.

● For external drives, the power on/off

switch incorporates a green LED. If this is not on, check the power cable connection and replace the cable if necessary. You can use the power cable from your monitor or another device to check that the connection is working.

If the power supply is present and all LEDs remain off, call for assistance.

The self-test fails (All three LEDS flashing.)

If there is a cartridge in the drive, remove it. Power down the drive and power it up again. If the self-test still fails, call for assistance.

all the LEDs on the front panel blink continually

Possible cause Potential solution

An internal drive fault has occurred. 1. Press and hold the Eject button for 6

seconds to reset the drive.

2. Turn the drive off and then on again. If the drive is a HP Surestore DLT1 internal drive, shut down and turn off the host server or workstation, then turn it back on and allow it to boot.

3. Call technical support if Power-On SelfTest (POST) continues to fail.

errors for which you cannot find the cause

Possible cause Potential solution

The AC power source may not be properly grounded. (HP Surestore DLT1e desktop drive only.)

1. Plug the HP Surestore DLT1e Desktop drive's power cable into a power outlet on the same circuit as the host server or workstation.

2. Plug the HP Surestore DLT1e Desktop Drive's power cable into a different power outlet.

problems during firmware update

drive does not go into firmware update mode

Possible cause Potential solution

There is a DLTtape cartridge in the drive.

Remove the cartridge from the drive and repeat the update process.

The drive and its controller hardware are not communicating properly.

The drive's hardware may be damaged and must be repaired. Refer to our World Wide Web Customer Care pages on

www.hp.com/support/dlt1 or call for

assistance.

code update failed

Possible cause Potential solution

1. The cartridge is not a valid code update cartridge

2. The cartridge does not contain a valid code update image file.

Obtain a valid code update cartridge and repeat the update process.

The cartridge contains a valid code update image file, but the flash EEPROM programming process fails.

The drive's controller hardware is probably damaged and must be replaced. The drive resets and runs Power-On Self-Test (POST) which fails if the flash EEPROM does not contain a valid code image. If this occurs, you must repair the drive before using it.

Refer to our World Wide Web Customer Care pages on www.hp.com/support/dlt1

or call for assistance.

interpreting the LEDs

The HP Surestore DLT1 tape drive has three LEDs (light emitting diodes) on the front panel which indicate drive status. The Ready switch is illuminated when power is switched on.

The tape drive performs a power on Power-On Self-Test (POST) whenever power is applied or the drive is reset. The test takes several seconds to complete, after which the drive is ready to use. The following takes place during POST:

1. The LEDS turn on all at once and then turn off.

2. If a cartridge is loaded, the Ready LED flashes during initialization and

remains illuminated after POST.

3. If there is no cartridge loaded, all LEDs turn off after POST.

Use the following table to interpret the LED sequences and the appropriate action to take.

Symptom Action

Drive fails to execute power-on self-test. LEDs remain off.

Check power is being supplied to the drive.

For external drives, the power on/off switch incorporates a green LED. If this is not on, check the power cable connection and replace the cable if necessary. You can use the power cable from your monitor or another device to check that the connection is working.

For internal drives try another power connector.

If the power supply is present and all LEDs remain off, contact the HP Customer Care

Center.

The Caution LED is illuminated. The drive may need cleaning. Load the DLT1

cleaning cartridge.

frequently asked questions

For further troubleshooting information, refer also to our Customer Support web site: http://www.hp.com/support/dlt1

How often should I clean the tape drive heads?

HP recommends that the drive is cleaned once every two weeks to ensure optimum performance.

Use only DLT1 cleaning cartridges to clean the heads. Refer to Cleaning for details.

What should I avoid when positioning the tape drive?

For internal drives, the server must provide forced cooling and be capable of drawing 2 cfm of air through the tape drive. Avoid blocking air vents. Ensure that empty bays have the appropriate blanking plates installed so that airflow is maintained.

For external drives, do not place the drive in a dirty environment, for example, on the floor, near a busy walkway, or near a door. Avoid locations subject to sudden temperature changes, such as near an outside door or window.

For specific environmental limits, refer to the

specifications for your tape drive model.

How many times can I use a DLTtape IV cartridge?

The recommended maximum number of passes over any single part of the tape is 1,000,000. In practical terms, this is equivalent to about 2,000 backup operations.

What types of tape cartridges can I use with my drive?

Only rely on the best media to protect your valuable data. Thanks to HP's rigorous testing programs, HP DLTtape IV data and DLT1 cleaning cartridges are the safest investment you can make.

Order online at: www.hp.com/go/storagemedia.

Important: You must use DLT1 cleaning cartridges with HP Surestore DLT1 tape drives.

How do I update the firmware?

You can update the firmware in HP Surestore DLT1 tape drives either by downloading over the SCSI bus or by loading a firmware update tape. See Firmware

Updates.

For how long can I archive tapes?

DLTtape IV cartridges will preserve the integrity of stored data for at least 30 years if proper storage conditions are observed. See Storing Cartridges.

summary of SCSI terminology

Note: this section discusses SCSI tape drive devices in general, although specific reference is made to the particular SCSI requirements of HP Surestore DLT1 tape drives where appropriate.

Various terms are used when describing SCSI devices. This section provides a brief summary. See What is SCSI for a more detailed discussion of the different

SCSI specifications.

There are three main factors that affect performance and cable length:

The speed of the data bus, which may be Fast, Ultra or Ultra 2. The width of the data bus, which may be Narrow or Wide. The voltage level of the interface, which may be single-ended (SE) or low voltage differential (LVD).

HP Surestore DLT1 drives are Ultra SCSI-2 wide devices designed to operate on a low voltage differential SCSI bus (LVDS) with a burst transfer rate of 40 MB/sec. Using the drive on a single-ended SCSI bus restricts performance. Do not use on the same bus as other single-ended devices as this will switch the LVDS host adapter into single-ended mode and restrict performance.

See SCSI Cables for more information about cable lengths.

setting up the SCSI bus

Each device on a SCSI bus, including the SCSI host bus adapter (HBA), must be configured with a unique 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 Ordering

Information).

SCSI ID numbers

SCSI IDs are numbered as follows:

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

SCSI IDs are usually set on the device itself (sometimes via configuration software), but some newer devices are capable of selecting an unused ID automatically when powered-up (these are known as "SCAM" devices). HP Surestore drives are not SCAM compliant.

SCSI ID 7 is reserved for the HBA because it has the highest priority on the bus. On wide buses, the priority runs from 7 (highest) to 0, then 15 down to 8 (lowest).

identifying SCSI IDs

If your computer already has devices connected to the SCSI bus, you will need to know their IDs to avoid any conflict with the new tape drive. Here are some methods of finding out the information:

The fastest and easiest way is to run HP Library & Tape Tools. HP Library & Tape Tools will check your SCSI configuration, including

the SCSI controller itself and any devices currently attached to it. Most computers display a list of SCSI devices and IDs during the boot-up process. This usually scrolls past very fast. If you press the [Pause] key, you should be able to halt the scrolling and view the list. If you have an Adaptec host adapter in the computer, it may have come with a Windows utility called SCSI Interrogator (SHOWSCSI.EXE) which displays information about connected devices. If you have Windows NT installed, select SCSI Adapters from the Control Panel, select a device in the Devices tab and click on Properties to view information about the device, including its SCSI ID. If you have Novell NetWare installed, use its LIST DEVICES command.

If none of these is available to you, try the following sources of information:

The details of all installed devices and settings may have been written down and stored with your computer's documentation (for new computers, this is often done by the supplier). Your HBA's documentation should tell you which settings it uses. Look at each device to find out its ID. This is usually easy with external devices. With internal devices, you will probably need the help of the device's documentation to identify the SCSI ID setting, which is usually set with jumpers.

Setting the SCSI ID

On internal HP Surestore drives, set the SCSI ID by attaching or removing jumpers at the rear of the drive. On external HP Surestore DLT1 drives, the ID is displayed on the rear panel and can be set by using a small screwdriver or a ball-point pen to press the little buttons above and below the number.

In either case, see the Getting Started Guide for more details. Note that host adapters check SCSI IDs only at power-on, so any changes will not take effect until the host system is power-cycled.

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:

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 Surestore DLT1 drives, active termination is required.

Correct termination can be achieved in four ways:

Using the host bus adapter: Often the HBA forms one end of the SCSI bus and provides termination.

If you have both internal and external devices attached to the same SCSI bus, the HBA will be in the middle of the cable and thus its termination must be disabled. See the host bus adapter's documentation for details of how to do this.

Using a terminated SCSI cable: Usually the internal SCSI cable in a PC-based server has a number of SCSI connectors along its length and a terminator at the end farthest from the host bus adapter. In this case, you must ensure that any devices attached to the cable have termination removed or disabled. Using a terminator attached to the last device on the bus: For other external devices, the terminator simply attaches to the spare SCSI connector of the last device.

termination power

SCSI terminators require power to function, which is supplied along the SCSI cable from one or more of the connected devices. Most host adapters provide power by default.

If you are using long SCSI cables and some of the devices do not provide termination power, it is best to connect these to the middle of the cable, so that devices which do provide termination power are nearer the ends of the cable, and thus closest to the terminators themselves.

plug and play adaptor cards

Most plug-and-play adapter cards have an auto-termination feature which, when the adapter is in the middle of the bus, can detect the terminators situated at either end of the SCSI bus and automatically turn off the on-board termination.

SCSI cables

Cables matter in SCSI systems. There are two factors to consider:

cable length

For LVD SCSI there is a maximum permissible length of 25 meters for a single device. With multiple devices the maximum combined internal/external length is 12 meters. For best performance, keep lengths to a minimum, but avoid very short overall lengths (less than 0.5 meters).

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.

For HP Surestore DLT1 internal drives, you need a SCSI ribbon cable with the correct termination. The drives have a 68-pin wide, high-density SCSI connector. If you are using an HP Surestore DLT1 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.

The cable provided with HP Surestore DLT1 external tape drives will attach to a computer with a wide LVDS SCSI connector (68 pins). If your server or host bus adapter is equipped with a very high density (VHD) wide SCSI connector, you will need to order a 68-pin HD-to-VHD converter or 68-pin HD-to-VHD cable. See

Ordering Information.

Look after your SCSI cables. In particular, take care when connecting or disconnecting not to damage the high-density connectors. Avoid putting excessive twists in external shielded cables, as this can cause premature failure.

what is SCSI?

The Small Computer Systems Interface (SCSI) is popular because it offers a fast and flexible method of connecting a variety of devices to a host computer. The SCSI standards define both the physical connections between the devices (cables and connectors) and the protocols devices use to communicate with each other.

the standards

There have been three general standards:

SCSI-1, which is now obsolete

SCSI-2, which is very common, and still a current standard

SCSI-3, which is an emerging set of linked standards that define

much more than the simple bus systems used by the earlier versions. SCSI-3 includes Fibre Channel, Wide SCSI, FireWire (IEE 1398), Low Voltage Differential (LVD or LVDS), and Fast Serial SCSI. Some of these standards are now being used on PC platforms

Another variant is ATAPI, which uses an EIDE physical bus to pass SCSI protocols to connected devices. Technically, this is not part of the SCSI-3 standards, although some operating systems (notably Windows NT) manage ATAPI devices as if they were fully SCSI.

SCSI is a backward-compatible standard, so that SCSI-2 and SCSI-3 devices can almost always be made to work together.

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 Adaptec 3940W) have more than one SCSI bus available on a single card.

SCSI in hp surestore tape drives

HP Surestore DLT1 drives are Ultra SCSI-2 wide devices designed to operate on a low voltage differential SCSI bus (LVDS) with a burst transfer rate of 40 MB/sec.

using wide and narrow devices together

Narrow SCSI devices can transfer data one byte at-a-time (and are sometimes called "8-bit SCSI" devices). They can conform to either the SCSI-2 or SCSI-3 protocols. They have a 50-pin connection to the SCSI bus.

Wide SCSI devices can transfer two bytes of data simultaneously ("16-bit SCSI"). They usually have a single, 68-pin connection to the SCSI bus. (This physical arrangement is part of the SCSI-3 specification.) They may support either SCSI-2 or SCSI-3 protocols.

Wide and narrow devices can simultaneously be connected to the same bus without problem, provided certain rules are followed.

Using HP Surestore DLT1 drives on a narrow bus will restrict performance.

Narrow devices used on a wide bus will not normally affect the performance of any wide devices connected

using SE and LVD, ultra and ultra 2 devices together

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

With single-ended (SE) SCSI, each signal travels over a single wire and each signal's value is determined by comparing the signal to a paired ground wire. Signal quality tends to decrease over longer cable lengths or at increased signal speed.

With low voltage differential (LVD) signaling, signals travel along two wires and the difference in voltage between the wire pairs determines the signal value. This enables faster data rates and longer cabling with less susceptibility to noise than SE signaling and reduced power consumption.

Using HP Surestore DLT1 drives on a single-ended SCSI bus restricts

performance. Do not use on the same bus as other single-ended devices as this will switch the LVDS host adapter into single-ended mode and restrict performance to SE speeds and SE cable length.

If you connect only LVD devices, the bus will operate in low voltage differential mode and Ultra2 speeds will be enabled. You can use a combination of Ultra and Ultra2 devices. Each device will operate at its optimum speed.

determining the SCSI id

Before you configure your system to support your new HP Surestore DLT1 drive, you need to determine what SCSI ID to use. The SCSI ID must be unique for each device attached to the SCSI bus. To list the existing devices, use the following command:

% /sbin/ioscan -f

The output of this should look similar to the following example:

Class I H/W Path Driver S/W State H/W Type Description

=======================================================================================

bc 0

root CLAIMED BUS_NEXUS graphics 0 1 graph3 CLAIMED INTERFACE Graphics ba 0 2> bus_adapter CLAIMED BUS_NEXUS Core I/O Adapter ext_bus 0 2/0/1 c700 CLAIMED INTERFACE Built-in SCSI target 2 2/0/1.4 tgt CLAIMED DEVICE

After you have installed the new tape drive, you can check that it has been attached successfully. From a shell window (hpterm/xterm), execute ioscan to display the list of attached devices.

For an HP Surestore DLT1, execute the following:

% /sbin/ioscan -f | grep "BNCHMARK"

The new lines should look similar to the following, where the 4 in the I field represents the instance of the SCSI tape driver, not the SCSI ID:

Class I H/W Path Driver S/W State H/W Type Description tape 4 2/0/1.5.0 stape CLAIMED DEVICE HP------BNCHMARK

creating the device files

Once you have verified the tape drive connection, you will need to create the appropriate device files for the drive. Normally, you would have rebooted your system after attaching the tape drive, and this process runs insf. However, if you have not rebooted your system since attaching the drive, you should run insf as follows before running mksf to create the device files:

% /sbin/insf -C tape

Create the device files for the devices using the mksf command as follows:

% /sbin/mksf -d stape -I <instance> [-n] [-u] /dev/rmt/X<name>

where:

Argument Description

-d stape Specifies the SCSI tape driver

-I <instance> Specifies the tape drive’s hardware address via the instance of the SCSI tape driver. The first instance is 0, the second 1, and so on.

[-n] Specifies no rewind; absence of this parameter indicates

rewind mode

[-u] Specifies Berkeley mode; absence of this parameter

indicates AT&T mode. Berkeley and AT&T modes differ in their read-only close behavior:

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).

In most cases, Berkeley mode should be used.

/dev/rmt/X<name> Specifies the path of the device file, where:

Specifies the tape device identifier. Use the next available identifier. You can examine the contents of /dev/rmt using the ls command to determine which identifiers have already been used.

<name> Specifies the short name (in HP-UX 9.x-style) of

the device file:

mnb No rewind, compression disabled,

Berkeley-mode device

hnb No rewind, compression enabled,

Berkeley-mode device

mnb No rewind, compression disabled,

Berkeley-mode device

hnb No rewind, compression enabled,

Berkeley-mode device

See the man page (man 1m mksf) for other options of the mksf command. The stape section covers the SCSI tape driver options. The man page man 7 mt describes the long filenames used in HP-UX 10.x.

example:

To create a device file with the following characteristics:

A hardware address specified by instance 5 (-I 5) No rewind (-n) Berkeley mode tape positioning on close (-u) A filename of 4mnb, where 4 is the tape device identifier (/dev/rmt/4mnb)

You would execute the following:

% /sbin/mksf -d stape -I 5 -n -u /dev/rmt/4mnb

You can check that the appropriate device file was created using the lssf command as follows:

% /sbin/lssf /dev/rmt/4mnb

This should produce the following output to show that the device file now exists:

stape card instance 0 SCSI target 6 SCSI LUN 0 berkeley no rewind BEST density at address 2/0/1.6.0 /dev/rmt/4mnb

Once the device files have been created, you should confirm that your new tape drive is working properly. See Verifying Installation.

determining the SCSI id

% lsdev -C |grep SCSI

This will produce output that looks similar to:

scsi0 Available 00-00-0S Standard SCSI I/O Controller hdisk0 Available 00-00-0S-0 1.0 GB SCSI Disk Drive rmt1 Defined 00-00-0S-2,0 Other SCSI Tape Drive

The SCSI ID is in the series 00-00-0S-X,0 where X is the SCSI ID. Review the list of existing SCSI IDs and choose an available ID to assign to your new tape drive.

configuring the device files

To install the HP Surestore DLT1 drive on an IBM workstation running AIX, you will need to create the appropriate device files for the drive.

NOTE: Do not choose the smit option of "4mm2gb" as the Tape Device Type. This

is reserved for Connor drives. If you use it with HP drives, you will get the error "Device to be configured does not match the physical device at the specified connection location".

To change to variable block mode, use the following procedure:

If you are using a graphics terminal running X-Windows, then at a Windows

terminal, type: smit tape

If you are using a non-graphics terminal, at the command line type:

% smit -C tape

If no device has been configured at this address before, select "add a tape drive" to set up the address. From the pop-up window, select "ost"

or "Other SCSI tape drive" as the tape drive you wish to change and choose connection addresses as appropriate.

Select from the window: "change/show characteristics of a tape drive"

From the pop-up window, select "ost" or "Other SCSI tape drive" as the tape drive you wish to change. Do not choose "4mm2gb".

Change the block size field to 0, and click on the "DO" button or press [Enter] to apply the change.

HP DLT1 drives will work with tar, cpio, backup, restore and dd. For systems other than the 43P, the drive is also boot-capable, provided a boot tape is generated using mkszfile and mksysb.

Once the device files have been created, you should confirm that your new tape drive is working properly. See Verifying Installation.

device file names under AIX

Use device filenames as listed below for the combination of Rewind on Close, Retension on Open, and Compression that you want:

Filename Rewind on Close Retension on Open Compression

/dev/rmtn

Yes No enabled

/dev/rmtn.1

No No enabled

/dev/rmtn.2

Yes Yes enabled

/dev/rmtn.3

No Yes enabled

/dev/rmtn.4

Yes No disabled

/dev/rmtn.5

No No disabled

/dev/rmtn.6

Yes Yes disabled

/dev/rmtn.7

No Yes disabled

The n in the filename is the instance number assigned to the drive by the operating system, where 0 is the first device, 1 is the second and so on.

Rewind on Close

Normally, the drive repositions the tape to BOT (Beginning of Tape) when the device file is closed. Using the no rewind option is useful when creating and reading tapes that contain multiple files.

Retension on Open

Retensioning consists of winding to EOT (End of Tape) and then rewinding to BOT, in order to reduce errors. If this option is selected, the tape is positioned at BOT as part of the open process. DLT1 drives do not require retensioning, so you should not use device fields that send retensioning commands.

Compression

Compression can be disabled or enabled.

determining the SCSI id (Linux)

Look at the output of dmesg to find out what SCSI channel number is used for each connection.

To find out the SCSI IDs in use on each channel:

run cat /proc/scsi/scsi

This will produce output similar to the following for each device:

Attached devices: Host: SCSI0 Channel:00 Id:00 Lun:00 Vendor: HP Model -----------Type: Direct-Access ANSI SCSI Revision 02

Look at the Id information to establish which Ids are in use.

configuring for an SCO system

To install the appropriate driver and device files on a SCO system, perform the following steps:

Run ‘mkdev tape’ as root.

Select ‘Configure SCSI tape drive’.

Select ‘Install tape drive’.

Select the appropriate SCSI adapter.

Select the appropriate SCSI bus.

Select the Target ID to match the SCSI ID set on the back of the drive.

Select the LUN to be 0.

Enter ‘y’ to update the SCSI configuration.

Enter the following details:

Vendor identification string: BNCHMARKDLT1 SCSI version to which the drive conforms: 2 Response Data Format (SCSI-2): 2 Generic device: 1

This procedure will automatically make the drive the default device, even if another device is already configured. You may want to edit /etc/conf/pack.c/stp/space.c to change the filemark handling on close. By default, it writes only one filemark for a write filemark ioctl(). See the comments in the space.c file.

Enter ‘q’ to leave unchanged the boot string that is displayed when the system is rebooted.

Enter ‘q’ to return to the Main Menu.

Enter ‘q’ to quit.

You are now prompted to rebuild the kernel and the kernel environment (which includes the device files). Perform both steps by answering ‘y’ when prompted, and select the new kernel to be booted by default. You can now use one of the following files, as appropriate, for backup operations:

/dev/nrStpX

if you require a no-rewind device

/dev/rStpX

if you require a rewind device

where X is the instance number as assigned to the drive by the operating system (0 is the first device, 1 is the second, and so on).

controlling compression with SCO

Because SCO does not have any compression/no-compression device files, you must use ‘tape setcomp’ to control the compression status of the drive as follows:

Command Compression Decompression

tape -a 0 setcomp disabled disabled tape -a 1 setcomp enabled disabled tape -a 2 setcomp disabled enabled tape -a 3 setcomp enabled enabled

If you have multiple drives, you must specify the appropriate device files in the command. For example:

% tape -a 0 setcomp /dev/nrStp2

Use ‘tape getcomp’ to tell you the current status of the drive.

NOTE: Do not use the SCO ‘mt’ utility. This is obsolete, and does not perform the

same function as ‘mt’ on other platforms. Use ‘tape’ to achieve the same result.

improving performance through block size on SCO

In order to improve performance, specify larger blocking factors for cpio and

tar. Use the ‘b’ option of tar with an argument of 20 or use the ‘B’ option of cpio. For example: % tar cvbf 20 /dev/rStpY ./*

% find / -print | cpio -ocB > /dev/rStpY

or, if you have a version of SCO UNIX earlier than 5.x:

% find / -print | cpio -ocB > /dev/rStpY

In each case, Y is the instance number as assigned to the drive by the operating system (0 is the first device, 1 is the second, and so on).

Alternatively, you can use the tape command as follows:

% tape -a 32768 setblk <device file>

This explicitly sets the block size used for the drive when you are using built-in applications such as cpio and tar. The <device file> is either /dev/nrStpY or /dev/rStpY as described above.

configuring for Linux systems

No changes are needed to support DLT1 on Linux platforms, however you should ensure that you have the relevant drivers loaded.

To see the device drivers loaded currently, execute an lsmod command, this will give output like:

Module Size Used by sgm 4376 1 ide-scsi 7200 0 lockd 30792 1 sunrpc 53316 1 st 24656 0 ncr53c8xx 52096 1 aic7xxx 136184 2

The lines of interest here are:

st This is the tape driver. Its presence in the output of the lsmod

command shows that the tape driver is loaded.

ncr53c8xx This is a SCSI chipset driver for the LSI Logic family of HBAs

(amongst others).

aix7xxx This is a SCSI chipset driver for the Adaptec 7xxx chipset family (such

as Adaptec 2940UW).

In order to communicate with a tape device, the operating system needs to have drivers for the tape and the underlying transport mechanism (the host bus adaptor) loaded. Ensure that both are available as either loadable modules (for example, usable with insmod and visible with lsmod) or are statically built into your kernel.

In order to determine if the drive has been detected by the tape driver at module load time, execute:

dmesg | grep "st"

This should find a number of lines. One should look like:

Detected SCSI tape st0 at scsi1, channel 0, id 5, lun 0

To load the tape driver module if it is not loaded as above, execute:

insmod st

to load it. This should happen naturally if your system is rebooted after attaching the drive.

In order to enable large transfers under Linux (>64 KB per write), edit the file /usr/src/linux/drivers/scsi/st_options.h and change the definition of ST_BUFFER_BLOCKS.

If you want requests to space to end of data to be faster, you should also enable ST_FAST_MTEOM in the same file. After changing this file, rebuild the modules and install the new binary. At the very least, this requires:

make modules make modules_install

from the /usr/src/linux directory. See your kernel documentation.
