Chapter 1. Overview

The operating system provides support for the following tape drives:

v EIDE Internal v SCSI Internal v SCSI External

Refer to the IBM 4690 OS V2: User’s Guide for more information on using the Streaming Tape Drive Utility.

The following table shows the tape drives supported.

Name Manufacturer Model Number Part Number

IBM 4.0/8.0GB TR4 Internal EIDE Tape Drive

Seagate ATAPI TapeStor 8000

IBM TR-4 4.0/8.0 GB Internal SCSI Tape Drive

IBM TR-4 4.0/8.0 GB External SCSI Tape Drive

TapeStor 8000 TR-4 4-8 GB Internal SCSI Tape Drive

TapeStore 8000 TR-4 4-8 GB External SCSI Tape Drive

Tape Capacity

A Travan TR-4 cartridge can store up to 4 GB of uncompressed data. However, the actual capacity per cartridge varies according to the number and size of the ﬁles to be stored. Because the Travan TR-4 cartridge is designed to store data from an entire hard disk, under normal conditions you should not need to insert a second tape. The large storage capacity allows the tape drive to be used in unattended mode (Remote Command Processor), which is a signiﬁcant advantage over tape drives that have smaller capacities and require user intervention to change tapes.

Low cost

Because only one cartridge is needed for most system backups, you save on tape cartridge cost. One Travan TR-4 cartridge may be cheaper than multiple smaller capacity tapes.

High Speed Data Transfer

The tape drive is capable of transferring raw data at 600 KB per second. Part of this data, Error Correction Code (ECC) data, is used to recover from read errors. The resulting throughput should be about 30 MB per minute when the tape drive is able to maintain streaming.

Buffered Data to Maintain Streaming

The tape drive’s RAM allows buffering of data in the hardware. The software in the Store Controller also has a buffer. With buffering in the hardware and the software, the number of underruns should be reduced.

Compatibility with the Floppy Drive

Because the tape drive attaches to either a SCSI or IDE cable instead of the ﬂoppy ribbon cable and does not use DMA channel 2, there is no contention with the ﬂoppy drive.

Installation Flexibility

The tape drives install in either a 5.25-inch or 3.5-inch bay inside the Store Controller.

Note: Because the TR-4 EIDE tape drive uses EIDE, it works with systems

that do not have a SCSI card.

Reliability

The Mean Time Between Failures (MTBF) is an impressive 200,000 hours. Reliability should be improved from previous tape drives because the ECC can recover up to 6 bad segments per block instead of the 3 bad segments per block.

Support

The following table shows the systems that support the TR-4 tape drive.

Description Machine Type

PC 300 6571*, 6573, 6581*, 6583, 6577, 6587, 6589 PC 700 6875, 6877, 6885, 6887

Notes:

1. The systems marked with an asterisk (*) cannot support the SCSI tape drive because

they have no PCI slot.

2. For the SCSI tape drives, a SCSI host adapter is required if one is not already in the

system.

The operating system does not support the TR-4 EIDE tape drive on IBM PS/2 (Microchannel) systems or IBM servers. However, the TR-4 SCSI tape drive is supported on the following IBM servers:

v PC Servers 310 v PC Servers 315 v PC Servers 325 v PC Servers 330

There may be additional desktop systems that support the tape drive that were not available at the time of this publication. In order for the tape drive to be supported on a system unit, all of the following conditions must be met:

v The tape drive is supported by the PC Company on a particular system. Contact

the PC Company to determine if a particular system supports the TR-4 tape drive.

v The system is supported by the operating system. To view a list of systems

supported by the operating system, see the Internet web address: http://www.raleigh.ibm.com/rds/storesys/4690/contmatx.htm.

The IBM 4690 Store System software does not support the formatting of a tape cartridge. The tapes must be preformatted.

2 TR-4 Tape Drive User’s Guide

Chapter 2. Tape Drive Installation

This chapter contains hardware and software installation instructions for the TR-4 tape drives. It contains instructions for both the EIDE tape drive and the SCSI internal and external tape drives.

Attention: Before installing this product, see “Safety” on page 25.

Attention: Tape drives are sensitive to static electricity discharge. The drives are

wrapped in a static-protective bag to prevent damage.

Installing the TR-4 EIDE Tape Drive

To install this drive, you must have the following: v An IDE controller that supports the ATA Packet Interface (ATAPI). The ATAPI

interface provides for communications between the store controller and the tape drive.

v The documentation that comes with your store controller.

Step 1. Preparing for Installation

1. Turn off the store controller and unplug the power cables from the power outlet

for the store controller and all attached peripherals.

2. Open the store controller. For speciﬁc information on opening your store

controller refer to the documentation that comes with your store controller. Become familiar with the store controller’s internal components, and determine what kind of conﬁguration you need to install.

3. Locate an available IDE connector on the secondary IDE cable in your store

controller. The tape drive only works on the secondary IDE cable. If your store controller does not have a secondary IDE cable, you must add one. Because most IBM PC computers do not include a secondary IDE cable, you must purchase an IDE cable separately. If your store controller does not have a secondary IDE cable, purchase an 18-inch, 40-pin ribbon cable at your computer dealer or electronics store.

4. Touch the static-protective bag containing the tape drive to an unpainted metal

surface on the store controller for at least 2 seconds. Remove the drive from the static-protective bag, holding the drive by the edges, and place it on the bag.

Step 2. Conﬁguring the IDE Drive

1. Set the IDE jumper ON for the setting that applies to your IDE conﬁguration.

The tape drive is preset at the factory to slave (SL). The IDE conﬁguration block pin assignments are:

7 and 8: Reserved 5 and 6:MA 3 and 4:SL 1 and 2:CS

where:

MA – Master

SL – Slave CS – Cable Select

Each of the two IDE cables (primary and secondary) normally has two connectors for attaching two IDE devices (master and slave). The C: drive must be on the primary IDE cable, and the tape drive must be on the secondary IDE cable. When choosing your conﬁguration, remember that two devices on the same IDE cable cannot be accessed at the same time. Performance is increased if you can avoid using both devices that are on the same IDE cable at the same time. A device will lock out another device on the same IDE cable until the operation is complete. Assuming that there are only two supported IDE devices, hard disks and tape drives, and that there can only be one tape drive and a maximum of two hard disks, the recommended conﬁgurations are:

Conﬁguration 1 Master on primary IDE:

C: drive

Slave on primary IDE:

none

Master on secondary IDE:

tape drive

Slave on secondary IDE:

none

In the conﬁguration above, you must conﬁgure the tape drive as the master (MA) by placing a jumper over vertical pins 5 and 6. There is no contention for the devices.

Conﬁguration 2 Master on primary IDE:

C: drive

Slave on primary IDE:

D: drive

Master on secondary IDE:

tape drive

Slave on secondary IDE:

none

In the conﬁguration above, you must conﬁgure the tape drive as the master (MA) by placing a jumper over vertical pins 5 and 6. The tape drive does not contend with other devices. The C: drive does contend with the D: drive. If a ﬁle access to one hard disk is in progress, a ﬁle access to the other hard disk must wait until the ﬁrst access is complete before starting the ﬁle access to the second hard disk.

This conﬁguration may be best when you have two hard disks and you have a need to run the tape drive while other applications are actively accessing the D: drive. There is no contention between the tape drive and the hard disks.

Conﬁguration 3

4 TR-4 Tape Drive User’s Guide

Master on primary IDE:

C: drive

Slave on primary IDE:

none

Master on secondary IDE:

D: drive

Slave on secondary IDE:

tape drive

In the conﬁguration above, you do not need to change the jumper on the tape drive, but you may need to change the jumper on the D: drive. Some hard disks have three possible jumper settings:

v master v master with a slave attached v slave

If you have one of these hard disks and it is currently a “master with no slave” and you are adding the tape drive as a “slave”, then you must change the jumpers on the hard disk from “master” to “master with a slave attached”. The C: drive does not contend with other devices. The D: drive does contend with the tape drive. If a tape operation is in progress, a ﬁle access to the D: drive must wait for the tape drive to complete a command before starting the ﬁle access. Any application waiting for the ﬁle access to complete cannot run during this time.

Alternatively, if a ﬁle access to the D: drive is in progress, the tape drive must wait for the ﬁle access to complete before a tape operation can begin. This may cause an underrun and the tape drive must stop, rewind a little, and start forward again, which impacts tape drive performance. The conﬁguration above may be best when you have two hard disks and you have no need to run the tape drive while other applications are actively accessing the D: drive. There is no contention between the C: and D: drive.

Conﬁguration 4 Master on primary IDE:

none

Slave on primary IDE:

none

Master on secondary IDE:

tape drive

Slave on secondary IDE:

none

The conﬁguration above assumes that all of your hard disks are SCSI instead of IDE. In this conﬁguration, you must conﬁgure the tape drive as the master (MA) by placing a jumper over vertical pins 5 and 6. There is no contention for the devices.

2. Refer to your store controller documentation to determine if your store

controller supports the cable select (CS) feature. With the cable select feature there is a special cable and the placement of the devices on the cable connectors determines whether a device is master or slave if the devices are set to CS. Most store controllers do not use this cable feature.

Chapter 2. Tape Drive Installation 5

Step 3. Mounting the Drive

1. Locate an available bay or space in your store controller to mount the tape

drive. The tape drive can be mounted in either a horizontal or vertical position. When mounted horizontally, the tape drive should be oriented so that the activity light is on the top left corner of the tape opening when looking at the tape drive from the front. The drive ﬁts in a 3.5-inch (1-inch high) standard bay.

Note: You can also mount the drive in a 5.25-inch (1.6-inch high) bay using the

5.25-inch mounting kit provided. When you attach the brackets to the sides of the 3.5-inch tape drive, you increase the width and height of the drive. The installation instructions are located on the mounting kit packaging.

2. Remove the cover plate from the bay selected. Slide the drive partially into the

bay. Align the drive-bay screw holes with the threaded holes in the drive housing (or bracket, if applicable).

3. Use the screws provided to secure the drive in the bay. Usually two screws are

used on each side. Some installations use the screw holes on the bottom (circuit board side) of the drive. Using the wrong size screws can damage the drive. Do not overtighten the screws. Check to ensure that the drive is securely mounted.

Step 4. Attaching the Cables

1. Locate the IDE and power connectors.

2. Locate the appropriate IDE cable and spare connector and attach it to the tape

drive. Use a 40-pin ribbon cable to connect the tape drive on the rear of the drive. The connector is keyed and ﬁts properly only one way if the ribbon is also keyed. Do not force the connector. If it does not attach easily, turn the connector around and try again. Ensure that line 1 of the IDE cable (usually color coded) aligns with pin 1 of the IDE connector. (Pin 1 is on the side closest to the power connector pins.)

3. Locate an unused power connector coming from the store controller power

supply. If all power cables are in use, purchase a dc Y-connector at your computer dealer or electronics store. Locate an available power cable and connect it to the 4-pin power connector on the tape drive . The cable connector is keyed and will ﬁt properly only one way.

Step 5. Completing the Installation

1. Be sure that the power and interface connectors are securely attached.

2. Be sure that the cables are neatly routed. They must not:

v Get in the way when the cover is replaced v Impede the power supply fan blade v Block air ﬂow paths

3. Replace the store controller cover and secure it in place.

4. Reconnect the ac power cord and cables. Turn on all attached devices; then turn

on the store controller.

5. When the Conﬁguration/Setup Utility is automatically entered, Select “Devices

and I/O Ports”.

6. Select “IDE Drives Setup...”.

7. Select each item in the list of IDE drives and verify that all of your hard disks

are deﬁned correctly. They should not be shown as “Not Installed”. To select

6 TR-4 Tape Drive User’s Guide

each item in the list, press the Enter key and use the arrow keys to move between items. Press the Enter key to select the item. Press the Esc key to return to the previous screen.

Also, make sure that the tape drive is reported as “Installed”. The order of the list is important. The drives should be deﬁned as:

Drive 0 is the master on primary IDE. Drive 1 is the slave on primary IDE. Drive 2 is the master on secondary IDE. Drive 3 is the slave on secondary IDE.

An empty item is reported as a “Hard Disk Drive” and “Not Installed”.

Note: The BIOS reports the tape drive incorrectly as a CD-ROM, but this does

not cause a problem with operation.

8. Save the conﬁguration and exit the Conﬁguration/Setup Utility.

Installing the TR-4 SCSI Internal Tape Drive

This section provides instruction for installing the SCSI internal tape drive. To install this drive, you must have the following:

v A SCSI bus adapter that is a single-ended SCSI and meets SCSI-2 (ANSI X3.T92)

or SCSI (ANSI X3.131-199X Rev.10h) standards

v The documentation that comes with your store controller

Step 1. Planning Your SCSI Conﬁguration

You must plan what SCSI ID to give the tape drive connected to the SCSI bus adapter. Each device on the adapter bus must have a unique ID. You cannot assign a device 7 because most SCSI bus adapters use that as their ID. Typically, assign the higher SCSI ID numbers to those devices that are most often used or are faster than other devices in the SCSI chain. The tape drive is preset at the factory to SCSI ID 0. Refer to your SCSI bus adapter documentation for more information.

For most Store Controllers, you can press F1 during startup to view your Store Controller and SCSI bus adapter conﬁguration. Other Store Controllers can have different procedures to view the conﬁguration. Some SCSI adapters have utility programs that allow you to view the SCSI conﬁguration, or you might have to physically inspect the installed SCSI devices to see how the IDs are set. For more information, refer to the documentation that comes with your Store Controller or SCSI bus adapter.

Step 2. Preparing for Installation

1. Turn off the Store Controller and unplug the power cables from the power

outlet for the Store Controller and all attached peripherals.

2. Open the Store Controller. For speciﬁc information on opening your Store

Controller refer to the documentation that comes with your Store Controller.

3. Touch the static-protective bag containing the tape drive to an unpainted metal

surface on the Store Controller for at least 2 seconds. Remove the drive from the static-protective bag, holding the drive by the edges, and place it on the bag.

Chapter 2. Tape Drive Installation 7

Step 3. Conﬁguring the SCSI Drive

1. Locate the SCSI conﬁguration block. The SCSI conﬁguration block pin

assignments are:

15 and 16

Enable terminator power

13 and 14

Enable termination

11 and 12

Reserved

9 and 10

Reserved

7 and 8

Enable parity

5 and 6

SCSI bit 2

3 and 4

SCSI bit 1

1 and 2

SCSI bit 0

2. Set the tape drive’s SCSI ID to the ID you selected. If you need to reset the

SCSI ID, refer to the following table, which contains SCSI ID Pin Assignments, for the ID jumper pin settings.

SCSI ID Bit 2, Pin 5, 6 Bit 1 Pin 3, 4 Bit 0 Pin 1, 2

0 OFF OFF OFF 1 OFF OFF ON 2 OFF ON OFF 3 OFF ON ON 4 ON OFF OFF 5 ON OFF ON 6 ON ON OFF 7ON ON ON

3. If the tape drive is the last device on the SCSI bus, it must be terminated. If

you need to terminate the device, place a jumper over pins 13 and 14 to enable termination. The tape drive is shipped with enable termination OFF.

4. Normally, the SCSI bus adapter supplies terminator power. Therefore, the tape

drive is shipped with enable terminator power OFF. If you need to enable terminator power, place the jumper over pins 15 and 16.

5. The parity is set to ON, enable parity, as the default (jumper over pins 7 and 8).

To disable parity, set the jumper to OFF.

Step 4. Mounting the Drive

1. Locate an available bay or space in your Store Controller to mount the tape

drive. The drive can be mounted in either a horizontal or vertical position. The drive ﬁts in a 3.5-inch (1-inch high) standard bay. When mounted horizontally, the tape drive should be oriented so that the activity light is on the top left corner of the tape opening when looking at the tape drive from the front.

8 TR-4 Tape Drive User’s Guide

Note: You can also mount the drive in a 5.25-inch (1.6-inch high) bay using the

2. Remove the cover plate from the bay selected. Slide the drive partially into the

bay. Align the drive-bay screw holes with the threaded holes in the drive housing (or bracket, if applicable).

3. Use the screws provided to secure the drive in the bay. Usually two screws are

Step 5. Attaching the SCSI and Power Cables

1. Locate the SCSI and power connectors. The tape drive connectors are:

v SCSI connector v SCSI connector - pin 1 v Power connector

2. Locate the SCSI bus cable (usually a 50-pin ribbon cable). The SCSI bus adapter

can be on the Store Controller system board or on an adapter installed in an expansion slot. If your Store Controller has a 68-pin cable, you need a 16-bit to 8-bit SCSI internal converter (IBM part number 32G3925 or equivalent).

3. There can be up to seven connectors on the cable from the SCSI bus adapter.

Locate an available SCSI connector and plug it into the tape drive. Ensure that line 1 of the SCSI cable (usually color coded) aligns with pin 1 of the SCSI connector.

4. Locate an available power cable and connect it to the 4-pin power connector on

the tape drive. If all power cables are in use, purchase a dc Y-connector at your computer dealer or electronics store. The power cable connector is keyed and ﬁts properly only one way. Do not force it. If it does not attach easily, turn the connector around and try it again.

Step 6. Completing the Installation

1. Be sure that the power and interface connectors are securely attached.

2. Be sure that the cables are neatly routed. They must not:

v Get in the way when the cover is replaced v Impede the power supply fan blade v Block air ﬂow paths

3. Replace the Store Controller cover and secure it in place.

4. Reconnect the ac power cord and cables. Turn on all attached devices; then turn

on the Store Controller.

Installing the External SCSI Drive

This section provides instructions for installing the external SCSI tape drive. The external SCSI model is essentially the internal SCSI model in a self-contained enclosure.

Chapter 2. Tape Drive Installation 9

Step 1. Planning Your SCSI Conﬁguration

Plan what SCSI ID to give the tape drive connected to the SCSI bus adapter. Each device on the adapter bus must have a unique ID. You cannot assign a device 7 because most SCSI bus adapters use this as their ID. Typically, assign the higher SCSI ID numbers to those devices that are most often used or are faster than other devices in the SCSI chain. The tape drive is preset at the factory to SCSI ID 0. Refer to your SCSI bus adapter documentation for more information.

Step 2. Preparing for Installation

1. Touch the static-protective bag containing the tape drive to an unpainted metal

surface on the Store Controller for at least 2 seconds. Remove the drive from the static-protective bag, holding the drive by the edges, and place it in a convenient space next to your Store Controller.

2. Turn off the Store Controller and unplug the power cables from the power

outlet for the Store Controller and all attached peripherals.

Step 3. Conﬁguring the Drive

The external SCSI model comes with the same defaults (termination disabled, terminator power disabled, and parity enabled) as the internal SCSI model. Refer to the instructions for the internal model, “Step 3. Conﬁguring the Drive”, if you have to open the external enclosure and adjust these settings.

The power switch is on the front panel of the tape drive. The following interfaces are on the rear panel of the external drive:

v SCSI ID-selection push switch v Two SCSI interface connectors v Power cord connector

Follow these instructions to install the tape drive:

1. The tape drive has two SCSI cable connectors. Connect the external tape drive

to your Store Controller’s SCSI bus adapter using a 50-pin ribbon SCSI cable (not provided) to one of the SCSI connectors on the back of the tape drive.

2. The end of a SCSI chain must be terminated to ensure the quality of the signal

throughout the SCSI chain. Use an 8-bit active or passive terminator. An active terminator (IBM part number 32G3919 or equivalent) provides improved signal quality. Determine if you need to terminate the tape drive:

v When the drive is the last SCSI device in the chain (or the only drive) attach

a terminator to the available SCSI connector on the back of the drive. Connect the second SCSI connector to the SCSI bus adapter cable.

v When the drive is within the chain do not terminate the tape drive. Connect

the ﬁrst SCSI connector to the cable from the previous device in the chain. Connect the second SCSI connector to the next device in the chain.

10 TR-4 Tape Drive User’s Guide

3. Locate the SCSI ID push switch on the back of the tape drive. Select the SCSI

ID for the drive by pressing the + or − button until the desired ID (0 through 7) appears in the window.

Step 4. Completing the Installation

1. Check your SCSI bus cable connections.

2. Connect one end of the power cord to the connector on the back panel of the

tape drive then the other end to a convenient wall outlet. Turn the drive ON. (The power switch is on the front panel of the tape drive.) Turn on the other attached devices; then turn on the Store Controller.

Upgrading the Firmware

You may need to apply the latest ﬁrmware to both the Store Controller and the tape drive.

Upgrading the Firmware for the Store Controller

In some cases, it may be necessary to upgrade the BIOS in the Store Controller so that it will work with the tape drive. You can ﬁnd the downloadable software to upgrade the ﬁrmware for the Store Controller at http://www.pc.ibm.com/us/ﬁles.html. Search on the model number of the Store Controller to ﬁnd all information relating to that model.

Upgrading the Firmware for the Tape Drive

If you have an early version of the tape drive hardware, you must apply the latest ﬁrmware to the tape drive. To determine if you have an early version of the tape drive, look for a chip on the tape drive with “WDC” written on it. If this chip is present, your tape drive is an early version. If you do not upgrade the ﬁrmware, the BIOS continues to give the errors 1762 and 162, and repeatedly takes you into the Conﬁguration/Setup Utility when the Store Controller is booted.

To upgrade the ﬁrmware for the tape drive:

1. Access the Internet web address: “http://www.pc.ibm.com/us/ﬁles.html”.

2. Click on “Search”.

3. Enter “tr4code” in the search ﬁeld and click on “Search”.

4. Click on “tr4code.exe”.

5. Download the ﬁle to the subdirectory of your choice.

6. Click on “tr4code.txt” and follow the installation instructions provided in this

ﬁle.

7. Follow the instructions, including rebooting the store controller.

Note: This process is automatic if you are using the SCSI tape drive. The

TAPESTRM and TAPESTRS commands are not used with the SCSI tape drive.

12 TR-4 Tape Drive User’s Guide

Chapter 3. Using the Tape Drive

This section provides information on using the tape drive features. It explains the procedures for loading and unloading tape cartridges and setting the write-protect switch.

Loading and Unloading Tape Cartridges

The front panel of the tape drive contains the cartridge opening and an activity light that indicates drive activity. When the activity light is OFF, the drive is not active.

Your tape drive has a ﬂip-up door that covers the cartridge opening when you do not have a tape cartridge in the drive. Once you insert a cartridge, the tape drive holds it in place using a positive locking mechanism.

Note: Do not remove the tape cartridge during drive operation. Complete any tape

operation and wait until the activity light is OFF before removing the

cartridge. To load a cartridge, insert it with the metal base plate down and the tape access door facing the drive.

To unload a cartridge, wait until the drive activity light is OFF and then pull the cartridge straight out.

Setting the Write-Protect Switch

Tape drive cartridges feature a write-protect switch located in the upper, left corner of the cartridge. You can set the switch to keep data from being written on the tape. Use this switch when you want to ensure that important data on the tape is not overwritten.

To return a cartridge to the unprotected write state, push the switch toward the end of the cartridge or unlocked position.

Reviewing Performance Considerations

The tape drive is ideally suited to streaming operations compared to multiple-start-and-stop tape movement. Frequent start-and-stop operations are often the result of data underruns. Start-and-stop operation can also increase the stress on both the drive and the media.

If you need to improve the performance of the tape drive, consider one or more of the following:

v Reduce the number of other applications that might be running simultaneously

with the backup application.

v For EIDE tape drives, consider moving the D: drive to the primary IDE cable if

it is on the secondary IDE cable.

Checking the Reliability of the Tape Data

After the Streaming Tape Drive Utility completes a list or restore operation, the message “Reliability: Tape drive recovered from xxx soft errors” appears, with xxx representing the number of 512-byte blocks that could not be read successfully on the ﬁrst attempt. However, the tape drive was able to recover the data successfully using either a read retry or ECC. The hardware speciﬁcations allow up to one soft error for every 102 KB of data, but testing has shown that a typical list or restore operation of 4 GB of data would only have one soft error for every 1 MB to 14 MB of data. For example, if a tape is full (it has 4 GB of data), it may have over 200 soft errors.

When the Streaming Tape Drive Utility is exited, a W660 B4/S055/E010 message is logged to record the number of soft errors encountered while the utility was running. If you format the W660 message using the Long Format Mode of the Scan System Log Data Utility in the Controller Events bucket, the following line appears:

DATA ERRORS: XXX UNDERRUNS: XXX PARITY ERRORS: XXX

The DATA ERRORS ﬁeld shows the number of soft errors that were recovered using a read retry. The UNDERRUNS ﬁeld is not used for the TR-4 Tape Drive and always shows 0. The PARITY ERRORS ﬁeld indicates the number of soft errors that were recovered using ECC.

Listing a Tape

The directory information for each ﬁle on the tape is located immediately before the ﬁle data for each ﬁle. It does not have a separate directory. Therefore, listing the data on the tape requires reading all of the data on the tape. A full tape of 4 GB of data would require about 2.5 hours to list the tape at the rate of 30 MB per minute. It is recommended to list the tape after each backup. The list can be used to verify that the data can be successfully read if required.

Erasing a Tape

Erasing a tape takes approximately three minutes. The process writes an End-of-Data marker at the beginning of the tape, winds the tape to the end, and then rewinds back to the beginning in order to retension the tape.

Use the tape drive only in equipment where the combination has been determined to be suitable by an appropriate certiﬁcation organization (for example, Underwriters Laboratories Inc. of the Canadian Standards Association in North America). Consider the following safety points:

v Install the drive in an enclosure that limits the user’s access to live parts, gives

adequate system stability, and provides the necessary grounding for the drive.

v Provide the correct voltages (+5 V dc and +12 V dc) based on the regulation

applied — Extra Low Voltage (SEC) for UL and CSA and Safety Extra Low Voltage for BSI and VDE (if applicable).

Chapter 5. Maintenance and Troubleshooting

This chapter describes several maintenance and troubleshooting procedures for the TR-4 EIDE Internal Tape Drive and the TR-4 SCSI Tape Drives.

Attention: To avoid electrical shock, unplug your store controller and all attached devices from electrical outlets before performing any troubleshooting procedure.

Maintenance

You should perform minimal maintenance to ensure that your tape drive operates in peak condition.

Caring for Tape Cartridges

The following points are guidelines for storing and using the cartridges:

v Do not open the tape access door of the cartridge or touch the tape itself. v Keep cartridges away from sources of electromagnetic ﬁelds, such as telephones,

dictation equipment, mechanical or printing calculators, motors, and bulk erasers. Do not place the cartridges on the store controller monitor or on the base unit of the store controller.

v Keep cartridges away from direct sunlight and heat sources, such as radiators or

warm air ducts.

v Keep cartridges free of moisture. Do not wet or submerge cartridges in any

liquid.

v Do not expose cartridges to temperature extremes. v Retension tape cartridges that have not been used for more than a month before

restoring or backing up data. Retensioning is the winding and rewinding of a tape cartridge. This action restores the proper tape tension to the media. The backup application software provides a function to retension a tape cartridge.

Cleaning the Tape Head

To properly maintain the drive, periodically clean the tape head. You do not need to perform any other periodic maintenance. Clean the tape head with a dry-process cleaning cartridge such as the Geneva DPCC-2000+. You can order a Geneva DPCC-2000+ cleaning cartridge directly from Geneva by calling 1-800-358-3559 and requesting part number GEN100-1 or by contacting your local Lexmark dealer.

The cleaning cartridge is good for 30 cleaning operations. Cleaning should be performed once a week. The cleaning process is simple to use; insert the cleaning cartridge into the tape drive, and the cleaning process is automatic. The entire process only takes a few seconds and is completed when the drive’s activity light stops ﬂashing.

Troubleshooting

EIDE Tape Drive

If the Store Controller is indicating an error during the boot process prior to the “IBM 4690 OS 386 V1 ...” message, the problem is not in the 4690 software. The problem is either a hardware failure, a hardware conﬁguration problem, downlevel BIOS, or downlevel ﬁrmware in the tape drive. Check for the following conditions:

v Make sure the jumpers are correct. On each ribbon cable, there must be no more

than one device jumpered as the “master” or “master with a slave attached”. If there are two devices on the ribbon cable, one, and only one, must be jumpered as the slave.

v Make sure the ribbon cable is attached correctly to both the devices and the

connector on the system board.

v Make sure the tape drive ﬁrmware is current. See “Upgrading the Firmware for

the Tape Drive” on page 11 to determine if you need to upgrade the ﬁrmware.

v Make sure the BIOS of the Store Controller is current. You can try upgrading the

BIOS to a more recent level.

If the Streaming Tape Drive Utility abends with a W639 B4/S056/E001 message, it indicates that either the TAPESTRS 5 or TAPESTRM 5 command was not executed, the Store Controller does not support the tape drive, or that the Store Controller could not detect the tape drive.

Make sure that the following conditions exist:

v The tape drive is on the secondary ribbon cable. v TAPESTRM 5 was run from Command Mode and TAPESTRS 5 was run from

the Supplemental Diskettes. After running the command, you must reboot your system.

v The Store Controller is an ISA bus system (that is, a PC 300 through PC 750

series).

v The Conﬁguration/Setup Utility accessed by pressing F1 when prompted during

the boot process can detect the tape drive. The tape drive should show as a CD-ROM and Installed. If the Conﬁguration/Setup Utility cannot detect the tape drive, check the connections and jumpers.

v The tape drive model is supported.

EIDE and SCSI Tape Drives

If the Streaming Tape Drive Utility abends with a W679 B4/S056/E157 message, it can indicate numerous problems including:

v The tape to which you are trying to write is only supported in read-only mode. v The device is not in a valid position. Make sure the drive is not upside down. v The device has a hardware problem.

If the Streaming Tape Drive Utility abends with a W679 B4/S056/E034 message, it can indicate numerous problems including:

v The tape to which you are trying to write is not supported by the tape drive.

The RHOMAT format tapes are not supported.

v The tape is not properly formatted. The tape drive only supports preformatted

TR-4 tapes.

24 TR-4 Tape Drive User’s Guide

Safety

v The device has a hardware problem.

The “Reliability: Tape drive recovered from xxx soft errors” message displayed by the Streaming Tape Drive Utility is a normal message unless the number indicated by xxx is high. The number can exceed several hundred if the tape is full (contains 4 GB of data). To determine if the number is high, divide the number into the number of MB of data on the tape. Within the hardware speciﬁcation, you can have up to 10 soft errors per 1 MB of data.

If the Streaming Tape Drive Utility logs a W660 B4/S055/E010 message, it is used for statistics and does not necessarily indicate an error.

If the Streaming Tape Drive Utility abends with read errors or if the number of soft errors becomes higher than normal, trying cleaning the tape drive. See “Cleaning the Tape Head” on page 23 for instructions.

Electrical current from power, telephone, and communication cables is hazardous. To avoid shock hazard, all cables should be disconnected before the store controller cover is opened and connected only after the store controller cover is closed. The power cord must be used with a properly grounded outlet.

Disconnecting

To disconnect your equipment:

v Turn all equipment OFF. v First, remove power cord from outlet. (In the United Kingdom, by law, the

power cord must be disconnected after the telephone line cable.)

v Remove signal cables from receptacles. v Remove all cables from devices.

Connecting

To connect your equipment:

v Turn all equipment OFF. v Attach all cables to devices. (In the United Kingdom, by law, the telephone cable

must be connected after the power cord.)

v Attach signal cables to receptacles. v Attach power cord to outlet. v Turn equipment ON.
