Chapter 1. Introduction

The IBM TotalStorage Linear Tape-Open (LTO) Ultrium 2 Tape Drive is a high-performance, high-capacity data-storage device that is designed to backup and restore Open Systems applications. The drive can be integrated into an enclosure, such as a desktop unit, tape autoloader, or tape library. The Ultrium 2 Tape Drive (called Generation 2) is the second-generation tape drive in the Ultrium series of products. It is available as Model T400 with a Small Computer Systems Interface (SCSI) or as Model T400F with a Fibre Channel interface.

The Ultrium 2 Tape Drive offers the following features: v Native storage capacity of up to 200 GB per cartridge (400 GB assuming 2:1

LTO Data Compression) v Native sustained data transfer rate of 35 MB per second (70 MB assuming 2:1

LTO Data Compression)

Table 1 gives additional features for each model of the drive.

Cartridge Compatibility

The Ultrium 2 Tape Drive (Generation 2) uses the IBM TotalStorage LTO Ultrium 200 GB Data Cartridge and is compatible with the cartridges of its predecessor, the IBM Ultrium Internal Tape Drive (called Generation 1). The Ultrium 2 Tape Drive performs the following functions:

v Reads and writes Generation 2 cartridges to Generation 2 format v Reads and writes Generation 1 cartridges to Generation 1 format v Does not write Generation 2 cartridges to Generation 1 format v Does not write Generation 1 cartridges to Generation 2 format

The Ultrium 2 Tape Drive reads tapes that have been written by other licensed Ultrium 2 drives. It also writes to tapes that can be read by other licensed Ultrium 2 drives.

In addition to using the IBM TotalStorage LTO Ultrium Data Cartridge with up to 200 GB capacity, the Ultrium 2 Tape Drive also offers read/write capability for certified LTO Ultrium tape cartridges.

Speed Matching and Channel Calibration

To improve system performance, the Ultrium 2 Tape Drive uses a technique called speed matching to dynamically adjust its native (uncompressed) data rate to the slower data rate of a server. With speed matching, the drive operates at one of five speeds when reading or writing the Generation 2 cartridge format to achieve a native data rate of 17.5, 21.9, 26.25, 30.63, or 35 MB per second (MB/s). If the server’s net (compressed) data rate is between two of the preceding native data rates, the drive calculates which of the two data rates at which to operate. (For example, if the server transfers data at 60 MB/s on the host bus, at 2:1 compression its net data rate is 30 MB/s. The drive will then dynamically choose to operate at a native data rate of 26.25 or 30.63 MB/s, whichever enables it to successfully receive the greatest amount of compressed data over the network.) Speed matching dramatically reduces backhitch, the condition that occurs when a tape stops, reverses, and restarts motion. A backhitch is usually the result of a mismatch between the data rates of the server and the drive.

System performance is further optimized by a feature called channel calibration,in which the drive automatically customizes each read/write data channel to compensate for variations in such things as the recording channel’s transfer function, the media, and characteristics of the drive head.

Sleep Mode

To conserve energy when circuit functions are not needed for drive operation, the Ultrium 2 Tape Drive features a power-management function that causes the drive’s electronics to enter a low-power mode known as sleep mode. To enter sleep mode, the drive must be inactive for a minimum of 15 minutes; to exit, the drive must receive a command across the SCSI or Fibre Channel interface, a command across the Library/Drive Interface (LDI or RS-422 interface), or a load or unload request. When in sleep mode, the drive’s response time to commands that do not require media motion increases by up to 10 microseconds. Commands that require media motion may be delayed an additional 100 milliseconds because the tape must be retensioned.

Chapter 1. Introduction 3

SCSI Attachment

To communicate with a server, the IBM TotalStorage LTO Ultrium 2 Tape Drive uses the Ultra160 LVD SCSI interface.

Physical Characteristics of the SCSI Interface

The Ultrium 2 Tape Drive contains a high-density, 68-pin, D-shell receptacle connector (HD68) for attachment to the server. The HD68 connector includes the connectors for the SCSI signal, the SCSI ID, and the drive’s power. The drive supports LVD SCSI cables with HD68 connectors.

For a list of available cables, see Appendix A, “Tools and Supplies” on page 95.

Speed

The Ultra160 LVD SCSI interface is backward compatible with older SCSI technology and is capable of data transmission at 160 MB/s. Ultra160 SCSI uses the three management features of the Ultra3 SCSI standard that specifically affect data transfer rate:

v Double transition clocking - a data-transfer technique that enables data rates

to double without increasing clock speed

v Domain validation - a procedure that detects and adjusts SCSI configuration

issues that might prevent interoperation between SCSI devices

v Cyclic redundancy check (CRC) - an error-checking technique

Because the cables, connectors, and terminators are the same for the Ultra160 and Ultra2 SCSI interfaces, devices with those interfaces can be mixed on the same bus and each device can operate at its fully rated speed.

4 IBM TotalStorage LTO Ultrium 2 Tape Drive

Address Assignments

Each device on a SCSI bus must have a SCSI identifier (ID) that identifies it to the server. When you install the Ultrium 2 Tape Drive, you can specify its SCSI ID in one of three ways:

v By attaching jumpers to the SCSI ID connector v By using your enclosure’s SCSI ID switch v If you are installing the drive into a tape library, by setting the SCSI ID through

the LDI or RS-422 interface For more information, see “Setting the SCSI ID (SCSI Drive Only)” on page 17.

Installing, Removing, or Resetting a Drive on an Active SCSI Bus

You can attach an Ultrium 2 Tape Drive to an active SCSI bus. However, the preferred and safest method of adding, removing, or resetting a drive is to power-off the system.

When adding, removing, or resetting a drive on an active SCSI bus, perform the following steps:

1. Quiesce the drive. The drive to be added, removed, or reset must not be

involved in any bus activity.

2. Disconnect power to the drive.

3. Connect or disconnect the SCSI bus cables to or from the drive’s SCSI

connector. Ensure that the SCSI bus remains intact from the server (initiator) to the terminator throughout the connection or disconnection process.

Note: Changing or moving the terminator disrupts the continuity of the SCSI

bus and interrupts any process on the bus.

Chapter 1. Introduction 5

Fibre Channel Attachment

To communicate with a server, the Ultrium 2 Tape Drive has one Fibre Channel interface (also called a port). In accordance with the standards of the American National Standards Institute (ANSI), the port runs Fibre Channel Protocol (which includes SCSI commands on the Fibre Channel) with ANSI-defined Fibre Channel Tape Support. The method by which the drive and server communicate is determined by the type of topology in which they reside and the type of connection that you choose.

Supported Topologies

The Ultrium 2 Tape Drive can be attached in a two-node configuration, either directly to a switch as a public device (switched fabric) or directly to a host bus adapter (HBA) as a private device. It can do so in a Point-to-Point topology (through an N_port or F_port) or Arbitrated Loop topology (through an L_port or FL_port).

Unless you set the drive to force an explicit configuration (by using the FC configuration/status connector; see “Step 4. Change the Link Services of the Drive (optional)” on page 24), the Ultrium 2 Tape Drive automatically configures to an L_port or an N_port when it boots. The type of port to which it configures depends on whether the drive recognizes the connection as a loop or a point-to-point connection:

v An L_port supports a Fibre Channel Arbitrated Loop connection to an NL_port or

FL_port.

v An N_port supports direct connection to another N_port or to an F_port (for

example, a director-class switch) in a point-to-point topology.

Attention: A Class I laser assembly, in the optical transceiver, is mounted on the Ultrium Fibre Channel electronics card. This laser assembly is registered with the Department of Health and Human Services and is in compliance with IEC825.

Regardless of the port to which you connect the drive, it automatically configures to a public device (through an F_port or FL_port to a switch) or to a private device (through an N_port or L_port by using direct attachment to a server).

Table 3 lists the topologies in which the Ultrium 2 Tape Drive can operate, the Fibre Channel server connections that are available, and the port (NL, N, FL, or F) through which communication must occur.

Speed

The Ultrium 2 Tape Drive’s Fibre Channel interface facilitates data at 2 Gb/s (200 MB/s). It automatically negotiates to a rate of 1 Gb/s (100 MB/s) if the system or switch to which it connects does not support the 2-Gb rate (if this is the case, you may experience performance degradation). You can force the drive to an explicit speed by placing jumpers on the Fibre Channel (FC) configuration/status connector. For more information, see “Step 4. Change the Link Services of the Drive (optional)”

on page 24.

Address Assignments

Each device on a Fibre Channel loop must have a Loop Identifier (LID) and a corresponding Arbitrated Loop Physical Address (AL_PA) to communicate with other devices in the topology. The AL_PA identifies the device on the loop. (LIDs and their corresponding AL_PAs are listed in Table 5 on page 21 and Table 6 on page 22.) You can set an AL_PA by using one of two methods known as soft addressing or hard addressing.

Soft addressing allows the drive to dynamically arbitrate the AL_PA with other Fibre Channel devices on the loop. Hard addressing allows you to choose the LID, which determines the corresponding AL_PA. The higher the AL_PA, the lower the priority of the device.

Generally, servers (initiators) require that devices use hard addressing; they do not support soft addressing. When setting addresses, assign the lowest AL_PA (and thus the highest priority) to the server; assign the highest AL_PA (and thus the lowest priority) to the drive.

To set soft or hard addressing, you must place jumpers on designated pins in the drive’s LID/status connector (see (2 in Figure 3 on page 15). The pin configuration for soft and hard addressing is defined in “Setting the Arbitrated Loop Physical Address (Fibre Channel Drive Only)” on page 19.

Chapter 1. Introduction 7

World Wide Names

Each Ultrium 2 Tape Drive has an 8-byte World Wide Node Name and an 8-byte World Wide Port Name that is assigned by IBM Manufacturing. The World Wide Node Name identifies the drive’s SCSI logical unit; the World Wide Port Name identifies the physical port on the drive. An enclosure queries the World Wide Names through the LDI or RS-422 interface; a server queries the Names through the Fibre Channel interface. The Ultrium 2 Tape Drive reports the World Wide Names to switches. You can use the World Wide Node Name or Wide Node Port Name to uniquely identify the drive on a SAN.

When your Ultrium 2 Tape Drive is installed in a tape library, you can change the World Wide Node Name and World Wide Port Name through the LDI or RS-422 interface. For instructions, refer to the documentation for your tape library.

Physical Characteristics of the Fibre Channel Interface

The Ultrium 2 Tape Drive attaches to Open Systems servers by using short-wave, multimode fiber optic cables. All cables feature LC-duplex connectors and are designated as 50/125 (50 refers to the diameter of the optical fiber and 125 refers to the diameter of the cable; both are measured in micrometers).

For a list of available cables, see Appendix A, “Tools and Supplies” on page 95.

Installing, Removing, or Resetting a Drive on an Active Fibre Channel

A Fibre Channel network supports dynamic drive attachment. When adding, removing, or resetting a drive on an active server or SAN, perform the following steps:

1. Quiesce the drive. The drive to be added, removed, or reset must not be involved in activity.

2. Connect or disconnect the Fibre Channel cables to or from the drive.

v Limit your movement. Movement can cause static electricity to build around

you.

v Always handle the Ultrium 2 Tape Drive carefully. Never touch exposed

circuitry.

v Prevent others from touching the Ultrium 2 Tape Drive. v Before you unpack and install the Ultrium 2 Tape Drive into an enclosure,

touch its static-protective packaging to an unpainted metal surface on the enclosure for at least 2 seconds. This reduces static electricity in the packaging and your body.

v When possible, remove the Ultrium 2 Tape Drive from its static-protective

packaging and install it directly into an enclosure without setting it down. When this is not possible, place the tape drive’s packaging on a smooth, level surface and place the tape drive on the packaging.

v Do not place the Ultrium 2 Tape Drive on the cover of the enclosure or on

any other metal surface.

The steps that follow describe how to install the Ultrium 2 Tape Drive into an enclosure.

Note: Depending on the type of enclosure, installation procedures may vary. Before

starting this installation, read these instructions and compare them to the drive installation instructions for your enclosure.

When installing the Ultrium 2 Tape Drive into an enclosure, refer to “Rear View of the SCSI Drive” on page 14 or “Rear View of the Fibre Channel Drive” on page 15.

Chapter 3. Installing 15

Step 1. Unpack the Drive

Unpack the Ultrium 2 Tape Drive and store the packaging. You may need the packaging if you return the unit for service.

Attention::

Acclimation time is required if the temperature of the drive when unpacked is different than the temperature of its operating environment (measured at the front of the bezel near the air intake area; see Figure 4). The recommended acclimation time is 4 hours after the drive has been unpacked or 1 hour after any condensation that you can see has evaporated, whichever is greater. When acclimatizing the drive, apply the following measures:

v If the drive is colder than its operating environment and the air contains sufficient

humidity, condensation may occur in the drive and damage it. When the drive has warmed to the operating temperature range (greater than 10°Cor50°F) and no danger of condensation is present (the air is dry), warm the drive more quickly by powering it on for 30 minutes. Use a diagnostic tape to test the drive before inserting a tape that contains data.

v If the drive is hotter than its operating environment, the tape can stick to the drive

head. When the drive has cooled to the operating temperature range (less than 40°Cor104°F), cool the drive more quickly by applying airflow for 30 minutes. Power-on the drive and use a diagnostic tape to test it before inserting a tape that contains data.

If you are uncertain about whether the temperature of the drive is within the recommended operating range or the humidity is sufficient to cause condensation, acclimate the drive for the full 4 hours.

Figure 4. Measuring the temperature of the operating environment. The temperature is measured at the front of the bezel, near the air intake area.

Step 2. Remove Power from the Enclosure

__ 1. Power-off the enclosure (or the unit that provides power to the drive) __ 2. Disconnect the power cord from both the electrical outlet and the enclosure.

16 IBM TotalStorage LTO Ultrium 2 Tape Drive

Step 3. Set the SCSI ID or Arbitrated Loop Physical Address

Perform one of the following steps: v If you are installing an Ultrium 2 Tape Drive that uses a SCSI interface (Model

T400), you must set the drive’s SCSI ID. For instructions, go to “Setting the SCSI ID (SCSI Drive Only)” on this page.

v If you are installing an Ultrium 2 Tape Drive that uses a Fibre Channel interface

(Model T400F), you must set the drive’s Arbitrated Loop Physical Address (AL_PA). For instructions, go to “Setting the Arbitrated Loop Physical Address (Fibre Channel Drive Only)” on page 19.

Setting the SCSI ID (SCSI Drive Only)

You can set the SCSI ID in one of three ways:

v By placing jumpers on the SCSI ID connector v By using a SCSI ID switch that is connected to the SCSI ID connector v By issuing a command from the library to set the SCSI ID through the drive’s LDI

interface

The sections that follow describe each method of setting the SCSI ID.

Setting the SCSI ID with Jumpers

You can set the SCSI ID on the Ultrium 2 Tape Drive by installing 2-mm jumpers on the drive’s SCSI ID connector (see 3 in Figure 2 on page 14). Your tape drive may come set to a default SCSI configuration, with jumpers already installed. To change the default SCSI configuration, contact your sales or or technical support representative. You can change the SCSI ID by rearranging, adding, or removing jumpers.

To set the SCSI ID: __ 1. Locate the SCSI ID connector (see 3 in Figure 2 on page 14). __ 2. Before attaching the SCSI bus cable to the server, decide the SCSI ID

number that you want. Make sure that the ID is not being used by another device.

__ 3. Referring to Figure 5 on page 18, find the ID number that you chose then

place jumpers on the connector pins as shown (use a pair of needle-nose pliers to connect the jumpers to the pins that are shaded).

Note: If you set the SCSI ID to 15, the drive will not necessarily be set to

that ID; instead, the drive will expect to receive the SCSI ID through a command over its LDI interface.

Chapter 3. Installing 17

Figure 5. SCSI ID settings on the SCSI ID connector

Setting the SCSI ID with a SCSI ID Switch

If your enclosure uses a SCSI ID switch (rather than jumpers), connect the switch to the drive’s SCSI ID connector (see 3 in Figure 2 on page 14). If any jumpers are pre-installed, be sure to remove them before connecting the switch. The SCSI ID switch must be compatible with the drive’s SCSI ID connector and must make an electrical connection between the same pins as the jumpers to achieve the same corresponding SCSI ID.

Setting the SCSI ID Through the LDI Interface

If you are installing the Ultrium 2 Tape Drive into a tape library, you can issue a command from the library to set the drive’s SCSI ID through the LDI interface. Make sure that the SCSI ID is set to 15 (see Figure 5). When configured to accept its SCSI ID through the LDI interface, the drive does not respond to SCSI commands until it receives a Set Configuration command through the interface.

Supplying TERMPOWER (SCSI Drive Only)

To supply TERMPOWER to the bus, locate one of the five jumpers shipped with the Ultrium 2 Tape Drive and place it on the SCSI ID connector as shown in the following figure. Place the jumper on the pins that are shaded.

Note that you must provide SCSI termination externally to the Ultrium 2 Tape Drive.

18 IBM TotalStorage LTO Ultrium 2 Tape Drive

A67E0049

Setting the Arbitrated Loop Physical Address (Fibre Channel Drive Only)

Each device on a Fibre Channel loop must have an Arbitrated Loop Physical Address (AL_PA) to communicate. The AL_PA identifies the device on the loop. To set the Ultrium 2 Tape Drive’s AL_PA, you must place jumpers on specific pins in the drive’s loop identifier (LID)/status connector. The placement of the jumpers indicates whether you want to choose the LID yourself (each LID corresponds to a specific AL_PA) or whether you want the drive to choose the AL_PA by arbitrating it with other devices on the loop. Valid LIDs and their corresponding AL_PAs are provided in this section.

Note: A Loop ID is part of a contiguous range of values; valid AL_PA values are

not in a contiguous range.

In addition to establishing the AL_PA, by moving Feature Switch 3 on the drive to ON or off you can set the drive so that it provides one of the following functions:

v Status about the Fibre Channel loop (through the use of external indicators in an

enclosure)

v Additional LIDs

The sections that follow describe how to select the AL_PA. They also describe how to set Feature Switch 3 so that the drive gives status about the loop or provides additional LIDs.

Chapter 3. Installing 19

Setting the Loop ID to Provide Status About the Loop

If Feature Switch 3 on the Ultrium 2 Tape Drive is set to OFF (see 1 in Figure 6), the LID/status connector 2 has the following definition:

v Pins 1, 2, 3, 4, 7, and 8 are inputs and are used to set the LID. v Pins 5 and 6 are used as outputs:

– Pin 5 has three states: off (ground), on (3.3 V), and alternating (between off

and on). Pin 5 will be off if the drive does not detect light on the Fibre Channel connector, if (while communicating as an L_port) the drive does not complete the Loop Initialization Protocol (LIP), or if (while communicating as an N_port) the drive does not complete logging in to the host or switch. Pin 5 will be on if the drive detects light, successfully completes the LIP process, or logs in to another port. After the drive has completed the LIP process, the pin will be alternating when the drive is receiving SCSI commands, and the pin will be on when the drive is not receiving SCSI commands.

– Pin 6 indicates that the drive detects light. If pin 6 is on but pin 5 is off, this

could indicate communication problems across the fiber cable.

– If the drive is installed in an enclosure, pins 5 and 6 may be used to support

external indicators, such as light-emitting diodes (LEDs), on the enclosure.

Note: If indicators are used on an enclosure, the drive does not report error

codes 8 and F (Fibre Channel problems) to the single-character display. Instead, pins 5 and 6 signal to the indicators that there is a problem.

v Pin 9 is ground.

Figure 6. Setting the Loop ID and the AL_PA. The feature switches are located on the bottom of the drive.

To set the AL_PA: __ 1. Determine an unused AL_PA for the drive and refer to Table 5 on page 21 for

its corresponding LID. __ 2. Locate the LID/status connector on the drive (see 2 in Figure 6). __ 3. Place jumpers on pins 1, 2, 3, 4, 7, and 8 as shown in Table 5 on page 21.

By using hard addressing, you can specify one of 62 valid AL_PAs for the

drive. If you place jumpers on the four top and bottom pins on the right (a

total of eight pins), the drive gets the AL_PA from a field in its vital product

data (VPD). (A tape library can set the AL_PA in the VPD through the LDI

interface.) If you do not place jumpers on any pins, the drive uses soft

addressing to determine the AL_PA.

Setting the Loop ID to Provide Additional Loop IDs

If Feature Switch 3 on the Ultrium 2 Tape Drive is set to ON (see 1 in Figure 6 on page 20), the LID/status connector 2 has the following definition:

v Pins 1 through 7 are used to set the LID. v Pin 8 overrides pins 1 through 7. If you place a jumper on pin 8, the drive uses

its vital product data (VPD) to set the AL_PA. A tape library can set the AL_PA in VPD through the LDI interface.

v Pin 9 is ground.

Note: Feature Switch 3 does not support LEDs on an enclosure. Therefore, when

Feature Switch 3 is set to ON, the drive can report Fibre Channel problems (error codes 8 and F) on the single-character display, but not by using the enclosure’s external indicators.

To set the AL_PA: __ 1. Determine an unused AL_PA address for the drive and refer to Table 6 for its

corresponding LID.

__ 2. Locate the LID/status connector on the drive (see 2 in Figure 6 on

page 20).

__ 3. Place jumpers on pins 1 through 7 as shown in Table 6 or on pin 8.

Step 4. Change the Link Services of the Drive (optional)

You can optionally change the link services (for example, the speed and type of topology) of your Fibre Channel drive. If you choose not to alter the link services, the drive defaults to a negotiated speed and operation in an FC-AL topology with a direct connection to the server.

In the following procedure, note that:

v Pin 5 is disconnected and is not represented in Table 7. v Pin 9 is ground.

To change the type of topology and the speed of the Fibre Channel drive: __ 1. Determine the type of topology in which you want to operate the Ultrium 2

Tape Drive and refer to Table 7 for its corresponding pin configuration.

__ 2. Determine the speed at which you want the Ultrium 2 Tape Drive to operate

and refer to Table 7 for its corresponding pin configuration.

__ 3. Locate the Fibre Channel (FC) configuration/status connector on the drive

(see 1 in Figure 7 on page 25).

__ 4. Place jumpers on the pins that you identified in steps 1 and 2.

To connect and test power to the Ultrium 2 Tape Drive: __ 1. Ensure that the enclosure (or unit that supplies power to the drive) is

powered off.

__ 2. Ensure that the power cord is disconnected from both the enclosure and the

power outlet.

__ 3. Connect the enclosure’s internal power cable to the power connector on the

drive (if you are using a SCSI drive, see 4 in Figure 2 on page 14; if you are using Fibre Channel drive, see 1 in Figure 3 on page 15). Ensure that

the connector is properly connected. __ 4. Connect the power cord to the enclosure and to the electrical outlet. __ 5. Review the location of the single-character display and the status light on

page 31 (if your drive does not have a bezel, note that the bulb of the status

light is recessed and the light is not visible until lit). To ensure that the drive

is receiving power, watch for the following while turning on the power to the

enclosure:

v The single-character display presents a series of random characters, then

becomes blank (not lit).

Note: If the single-character display does not come on, the drive

may not be getting power.

v The status light briefly becomes solid amber, then becomes solid green. __ 6. Power-off the enclosure. __ 7. Disconnect the power cord from both the enclosure and the electrical outlet.

Step 7. Connect the Internal SCSI or Fibre Channel Cable

__ 1. Perform one of the following procedures:

v If you are using a SCSI drive (Model T400), connect the enclosure’s

internal SCSI cable to the SCSI connector on the drive (see 2 in Figure 2 on page 14).

v If you are using a Fibre Channel drive (Model T400F), connect the

enclosure’s internal Fibre Channel cable to the Fibre Channel connector on the drive (see 5 in Figure 3 on page 15).

__ 2. Ensure that the connector is properly connected.

Chapter 3. Installing 27

Step 8. Connect the Internal LDI Cable (optional)

Note: Use this step only if you are installing the Ultrium 2 Tape Drive into a library

control system. The drive uses the Library/Drive Interface (LDI) to communicate with a tape library.

__ 1. Replace the cover on the enclosure. __ 2. Connect the power cord to both the enclosure and the electrical outlet, then

power-on the enclosure.

__ 3. Run one or more of the following tape drive diagnostics. If an error code

appears on the single-character display, go to Table 15 on page 67.

v Function Code 1 - Run Tape Drive Diagnostics (see page 36). v Function Code 6 - Run Wrap Test (for a SCSI drive, see page 39; for a

Fibre Channel drive, see page 40).

v Function Code 7 - Run LDI Wrap Test (see page 41).

__ 4. Power-off the enclosure, then disconnect the power cord from both the

enclosure and the electrical outlet.

Step 10. Install the Device Drivers

For information about installing device drivers, refer to the documentation for your enclosure.

Step 11. Connect the External SCSI or Fibre Channel Interface to the Server

Perform one of the following steps: v If you are using a SCSI drive (Model T400), connect the enclosure’s external

SCSI cable to the SCSI connector on the server. For instructions, go to “Connect the External SCSI Interface to the Server” on this page.

v If you are using a Fibre Channel drive (Model T400F), connect the enclosure’s

external Fibre Channel cable to the Fibre Channel connector on the server. For instructions, go to “Connect the External Fibre Channel Interface to the Server”

on page 29.

Connect the External SCSI Interface to the Server

To connect the enclosure to the SCSI bus: __ 1. Connect an external SCSI bus cable to both the enclosure and the server

(for the location of the connectors, refer to the documentation for your enclosure and server).

__ 2. Run the appropriate SCSI attachment verification procedure from your server

(for instructions, refer to the IBM Ultrium Device Drivers Installation and User’s Guide). If a SCSI error occurs, refer to “Using Sense Data” on page 71.

28 IBM TotalStorage LTO Ultrium 2 Tape Drive

If you want to power a device on or off while it is connected to the same SCSI bus as an Ultrium 2 Tape Drive, you can do so if, during the power-on cycle, you quiesce all devices (including the Ultrium 2 Tape Drive) on the bus.

Connect the External Fibre Channel Interface to the Server

To connect the enclosure to the Fibre Channel interface: __ 1. Connect an external fiber cable to both the enclosure and the appropriate

attachment (server, switch, or hub). For the location of the connectors and for information about attaching the fiber cable, refer to the documentation for your enclosure and for your server, switch, or hub.

Note: A drive with a Fibre Channel interface can be ordered with several

lengths of fiber cabling, up to 61 m (200 ft). For ordering information, see Table 16 on page 95.

__ 2. Run the appropriate Fibre Channel attachment verification procedure from

your server (for instructions, refer to the IBM Ultrium Device Drivers Installation and User’s Guide). If a SCSI error occurs, refer to “Using Sense Data” on page 71.

Step 12. Connect the External LDI Interface to the Server (optional)

Use this step only if your enclosure requires an LDI interface.

To perform a checkout of the Ultrium 2 Tape Drive, connect the enclosure’s external LDI cable to the server (for the location of the external LDI connector, refer to the documentation for the enclosure).

Step 13. Configure the Tape Drive to the Server, Switch, or Hub

Unload Button

The unload button (2 in Figure 9 on page 31) enables you to perform the following functions:

v Rewind the tape into the cartridge and eject the cartridge from the tape drive. For

more information, see “Removing a Tape Cartridge” on page 35.

v Enter or exit maintenance mode, or perform diagnostic or maintenance functions.

For more information, see “Selecting a Diagnostic or Maintenance Function” on page 36.

v Perform a panic reset of the drive. Attention: If the tape drive detected a

permanent error and displayed an error code, it automatically forces a drive dump (also known as a save of the firmware trace). If you perform a panic reset of the drive, the existing dump will be overwritten and lost. To perform a panic reset, press and hold the unload button on the drive for 10 seconds. The drive forces a dump and overwrites the existing dump. The drive then reboots to allow communication.

Single-Character Display

The Ultrium 2 Tape Drive features an LED (3 in Figure 9 on page 31) that presents a single-character code for:

v Diagnostic or maintenance functions v Error conditions and informational messages

Single Red Dot

Table 9 on page 36 lists each single-character code that is used for diagnostic or maintenance functions. Table 15 on page 67 lists the codes for error conditions and informational messages. If multiple errors occur, the code with the highest priority (represented by the lowest number) displays first. When the error is corrected, the code with the next highest priority displays, and so on until no errors remain.

The single-character display is blank during normal operation. However, if a drive dump is present while the drive is in maintenance mode, a single red dot illuminates on the display. To copy the dump to tape, see Function Code 5 in Table 9 on page 36.

The red dot turns off when you obtain the dump (by using an FMR tape a SCSI command, or a library command). If no dump is present while the drive is in maintenance mode, the single red dot does not illuminate.

Chapter 4. Operating 33

Inserting a Tape Cartridge

To insert a tape cartridge:

1. Ensure that the Ultrium 2 Tape Drive is powered-on.

2. Ensure that the write-protect switch is properly set (see “Setting the Write-Protect Switch” on page 50).

3. Grasp the cartridge so that the write-protect switch faces you (see 1 in Figure 10).

4. Slide the cartridge into the tape load compartment.

Notes:

a. If the cartridge is already in an ejected position and you want to reinsert it,

remove the cartridge then insert it again.

b. If the cartridge is already loaded and you cycle the power (turn it off, then

on), the tape will reload.

Function Code 6 - Run SCSI or Fibre Channel Wrap Test

Causes the drive to perform one of the following:

v A check of the SCSI circuitry from and to the SCSI connector v A check of the Fibre Channel circuitry from and to the Fibre Channel connector or fiber cable

To run the test, determine whether your drive uses a SCSI or Fibre Channel interface, then choose one of the following procedures.

Running a SCSI Wrap Test

This test evaluates the SCSI circuitry. A SCSI LVD wrap plug, a SCSI LVD terminator, and a Y-cable are required for this procedure. Note: You can terminate the Generation 1 drive internally while running the SCSI wrap test. Internal termination is not built into the Generation 2 drive, therefore you must run the SCSI wrap test by using a Y-cable and external termination.

Before you select this function, you must configure the drive to supply term power, terminate the SCSI bus, and attach the SCSI wrap plug. Configure the drive to supply term power by placing a jumper on pin 6 of the drive’s SCSI ID connector (as shown by the shaded area in the figure below).

Updating the Firmware

Attention: When updating firmware, do not power-off the tape drive until the

update is complete, or the firmware may be lost.

Periodically check for updated levels of drive firmware by visiting the web at http://www.ibm.com/storage/lto. You can update your drive’s firmware by:

v Obtaining the new firmware image and downloading it to the drive through the

SCSI or Fibre Channel interface

v Obtaining the new firmware image and downloading it to the drive through the

LDI or RS-422 interface

v Loading the firmware from a field microcode replacement (FMR) tape cartridge For instructions about how to obtain a new firmware image or FMR tape, visit the

preceding web site. To update the firmware, refer to the following sections.

Updating Firmware through the SCSI or Fibre Channel Interface

Attention: SCSI drives and Fibre Channel drives require different firmware

images.

When you update the tape drive’s firmware by using the SCSI or Fibre Channel interface, the procedure varies, depending on whether your server uses an IBM tape device driver or a non-IBM tape device driver (such as a driver from Sun, Hewlett-Packard, or Microsoft).

For instructions about updating firmware from a server that uses an IBM tape device driver, refer to the IBM Ultrium Device Drivers Installation and User’s Guide.

To update firmware from a server that uses a non-IBM tape device driver, refer to the documentation for that device driver.

Updating Firmware through the Library/Drive Interface

The Ultrium 2 Tape Drive includes a firmware update feature that allows a tape library to download firmware to the drive by using the Library/Drive Interface (LDI) while the drive performs normal host operations on logical unit number (LUN) 0 of the SCSI Protocol Interface. The update typically takes 63 seconds and a maximum of 140 seconds. To activate the new firmware, cycle power to the drive, or unload the drive and issue a Power-on Reset command. The command may be received by the SCSI interface or the LDI (RS-422) interface.

Note: If a Power-on Reset command is received while a cartridge is loaded in the

drive, the drive will respond with a Check Condition. It will not activate the new code level until you cycle power, or until you receive a Power-on Reset command when the drive does not contain a cartridge.

Chapter 4. Operating 45

Updating the Firmware with an FMR Tape Cartridge

Attention: SCSI drives and Fibre Channel drives require different firmware

images.

To update the Ultrium 2 Tape Drive’s firmware from an FMR tape cartridge:

1. Ensure that the tape drive is unloaded.

2. Place the drive in maintenance mode by pressing the unload button three times within a 1.5-second interval. The status light becomes solid amber, which means that the drive is in maintenance mode.

3. Press the unload button once per 1.5 seconds until 2 displays, then press and hold the button for 3 seconds. When C flashes, the drive is waiting for a cartridge.

4. Insert the FMR tape cartridge. 2 flashes, the drive loads the updated firmware from the cartridge, and the status light flashes amber. When the update completes successfully, 0 displays and the cartridge automatically ejects.

The drive resets itself and automatically activates the new firmware.

If the update fails, an error code displays. To resolve the error, locate the code in Table 15 on page 67.

Chapter 5. Using the Media

The IBM TotalStorage LTO Ultrium 2 Tape Drive uses the following cartridge types:

v IBM TotalStorage LTO Ultrium 200 GB Data Cartridge (Generation 2) v IBM LTO Ultrium Cleaning Cartridge v IBM TotalStorage Cleaning Cartridge (Ultrium LTO 2)

The Ultrium 2 Tape Drive (Generation 2) is compatible with the cartridges of its predecessor, the IBM Ultrium Internal Tape Drive (Generation 1). Cartridge compatibility for the Ultrium 2 Tape Drive is as follows:

Figure 11 shows the IBM TotalStorage LTO Ultrium 200 GB Data Cartridge and its components.

Figure 11. The IBM TotalStorage LTO Ultrium 200 GB Data Cartridge

Data Cartridge

In addition to using LTO Ultrium 2 Tape Cartridges with up to 200 GB capacity, the tape drive reads and writes to certified LTO Ultrium Tape Cartridges that have capacities of 100, 50, 30, and 10 GB. If you want to control the capacity of the cartridge (for example, if you want to limit the capacity to obtain a faster seek time) you can do so by issuing the SCSI command SET CAPACITY. For information about this command, refer to the IBM TotalStorage LTO Ultrium Tape Drive SCSI Reference.

To ensure that your tape drive conforms to IBM’s specifications for reliability, use only IBM TotalStorage LTO Ultrium Tape Cartridges. You may use other LTO-certified data cartridges, but they may not meet the standards of reliability that are established by IBM. The IBM TotalStorage LTO Ultrium 200 GB Data Cartridge cannot be interchanged with the media used in other IBM non-LTO Ultrium tape products.

The IBM TotalStorage LTO Ultrium 200 GB Data Cartridge contains 1/2-inch, dual-coat, metal-particle tape that has a native data capacity of 200 GB (400 GB at 2:1 compression). When processing the tape, the IBM TotalStorage LTO Ultrium 2 Tape Drive uses a linear, serpentine recording format, and reads and writes data on 512 tracks, eight tracks at a time. The first set of eight tracks is written from near the beginning of the tape to near the end of the tape. The head then repositions to the next set of eight tracks for the return pass. This process continues until all tracks are written and the tape is full, or until all data is written.

The IBM TotalStorage LTO Ultrium 200 GB Data Cartridge includes a Linear Tape-Open Cartridge Memory (LTO-CM) chip (1 in Figure 11 on page 47), that contains information about the cartridge and the tape (such as the name of the manufacturer that created the tape), as well as statistical information about the cartridge’s use. Whenever you unload a tape cartridge, the tape drive writes any pertinent information to the cartridge memory. The storage capacity of the LTO-CM is 4096 bytes.

The cartridge door 2 protects the tape from contamination when the cartridge is out of the drive. Behind the door, the tape is attached to a leader pin 3. When you insert the cartridge into the drive, a threading mechanism pulls the pin (and tape) out of the cartridge, across the drive head, and onto a non-removable takeup reel. The head can then read or write data from or to the tape.

The write-protect switch 4 prevents data from being written to the tape cartridge. The label area 5 provides a location for you to place a label. Affix only a bar code label. When affixing a label, place it only in the recessed label area. A label that extends outside of the recessed area can cause loading problems in the drive. The insertion guide 6 is a large, notched area that prevents you from inserting the cartridge incorrectly.

You can order tape cartridges with the bar code labels included, or you can order custom labels. To obtain tape cartridges and bar code labels, see “Ordering Media Supplies” on page 63.

The IBM TotalStorage LTO Ultrium 200 GB Data Cartridge has a nominal cartridge life of 5000 load and unload cycles. The Generation 2 cartridge is purple; the Generation 1 cartridge is black.

48 IBM TotalStorage LTO Ultrium 2 Tape Drive

Cleaning Cartridges

The Ultrium 2 Tape Drive is compatible with the IBM LTO Ultrium Cleaning Cartridge (part number 08L9124) and the IBM TotalStorage Cleaning Cartridge (Ultrium LTO 2) (part number 35L2086).

The IBM TotalStorage Cleaning Cartridge functions with Ultrium-format tape drives that are produced by compliance-verified manufacturers. The cartridge lets you buy and use a single cleaning cartridge for all of your tape drives, rather than spend time and money to support several different cleaning cartridges.

The IBM TotalStorage Cleaning Cartridge (Ultrium LTO 2) is downward-compatible with the Ultrium Internal Tape Drive (Generation 1). To enable your Generation 1 drive to use the cartridge, simply download and install the latest drive firmware (for instructions, see “Updating the Firmware” on page 45).

The drive itself determines when a head needs to be cleaned. It alerts you by displaying C on the single-character display and causing the status light to become flashing amber. To clean the head, insert the cleaning cartridge into the tape load compartment (see Figure 10 on page 34). The tape drive performs the cleaning automatically. When the cleaning is finished, the drive ejects the cartridge.

To remove a cleaning cartridge, see “Unload Button” on page 33. The IBM TotalStorage Cleaning Cartridge (Ultrium LTO 2) and the IBM LTO Ultrium Cleaning Cartridge are valid for 50 uses (the cartridge’s LTO-CM chip tracks the number of times that the cartridge is used).

Chapter 5. Using the Media 49

Setting the Write-Protect Switch

The position of the write-protect switch on the tape cartridge (see 1 in Figure 12) determines whether you can write to the tape:

v If the switch is set to v If the switch is set to unlocked (black void), data can be written to the tape.

To set the switch, slide it left or right to the desired position.

Attention: Do not insert a damaged tape cartridge into your Ultrium 2 Tape Drive. A damaged cartridge can interfere with the reliability of the drive and may void the warranties of the drive and the cartridge. Before inserting a tape cartridge, inspect the cartridge case, cartridge door, and write-protect switch for breaks. If you need to recover data from a damaged cartridge, contact your OEM Product Application Engineer (PAE).

Incorrect handling or an incorrect environment can damage the LTO Ultrium Tape Cartridge or its magnetic tape. To avoid damage to your tape cartridges and to ensure the continued high reliability of your IBM TotalStorage LTO Ultrium 2 Tape Drive, use the following guidelines.

50 IBM TotalStorage LTO Ultrium 2 Tape Drive

Provide Training

v Post procedures that describe proper media handling in places where people

gather.

v Ensure that anyone who handles tape has been properly trained in handling and

shipping procedures. This includes operators, users, programmers, archival services, and shipping personnel.

v Ensure that any service or contract personnel who perform archiving are properly

trained in media-handling procedures.

v Include media-handling procedures as part of any services contract. v Define and make personnel aware of data recovery procedures.

Ensure Proper Packaging

v When you ship a cartridge, ship it in its original or better packaging. v Always ship or store a cartridge in a jewel case. v Use only a recommended shipping container that securely holds the cartridge in

its jewel case during transportation. Ultrium Turtlecases (by Perm-A-Store) have been tested and found to be satisfactory (see Figure 13). They are available at www.turtlecase.com.

Figure 13. Tape cartridges in a Turtlecase

v Never ship a cartridge in a commercial shipping envelope. Always place it in a

box or package.

v If you ship the cartridge in a cardboard box or a box of a sturdy material, ensure

the following: – Place the cartridge in polyethylene plastic wrap or bags to protect it from dust,

moisture, and other contaminants.

– Pack the cartridge snugly; do not allow it to move around. – Double-box the cartridge (place it inside a box, then place that box inside the

shipping box) and add padding between the two boxes (see Figure 14 on page 52).

Chapter 5. Using the Media 51

Figure 14. Double-boxing tape cartridges for shipping

Provide Proper Acclimation and Environmental Conditions

v Before you use a cartridge, let it acclimate to the normal operating environment

for 1 hour. If you see condensation on the cartridge, wait an additional hour.

v Ensure that all surfaces of a cartridge are dry before inserting it. v Do not expose the cartridge to moisture or direct sunlight. v Do not expose recorded or blank cartridges to stray magnetic fields of greater

than 100 oersteds (for example, terminals, motors, video equipment, X-ray equipment, or fields that exist near high-current cables or power supplies). Such exposure can cause the loss of recorded data or make the blank cartridge unusable.

v Maintain the conditions that are described in “Environmental and Shipping

Specifications for Tape Cartridges” on page 62.

Perform a Thorough Inspection

After purchasing a cartridge and before using it, perform the following steps:

v Inspect the cartridge’s packaging to determine potential rough handling. v When inspecting a cartridge, open only the cartridge door. Do not open any other

part of the cartridge case. The upper and lower parts of the case are held together with screws; separating them destroys the usefulness of the cartridge.

v Inspect the cartridge for damage before using or storing it. v Inspect the rear of the cartridge (the part that you load first into the tape load

compartment) and ensure that there are no gaps in the seam of the cartridge case (see 4 in Figure 17 on page 56). If there are gaps in the seam (see Figure 15 on page 53), the leader pin may be dislodged. Go to “Repositioning or Reattaching a Leader Pin” on page 55.

52 IBM TotalStorage LTO Ultrium 2 Tape Drive

Figure 15. Checking for gaps in the seams of a cartridge

v Check that the leader pin is properly seated. v If you suspect that the cartridge has been mishandled but it appears useable,

copy any data onto a good cartridge immediately for possible data recovery. Discard the mishandled cartridge.

v If you must recover data from a damaged cartridge, contact your service

representative.

v Review handling and shipping procedures.

Handle the Cartridge Carefully

v Do not drop the cartridge. If the cartridge drops, slide the cartridge door back and

ensure that the leader pin is properly seated in the pin-retaining spring clips (see 2 in Figure 16 on page 55). If the leader pin has become dislodged, go to “Repositioning or Reattaching a Leader Pin” on page 55.

v Do not handle tape that is outside the cartridge. Handling the tape can damage

the tape’s surface or edges, which may interfere with read or write reliability. Pulling on tape that is outside the cartridge can damage the tape and the brake mechanism in the cartridge.

v Do not stack more than six cartridges. v Do not degauss a cartridge that you intend to reuse. Degaussing makes the tape

unusable.

Chapter 5. Using the Media 53

Examples of Cartridge Problems

Example: Improper Placement of Leader Pin

The leader pin is misaligned. Perform the following steps:

1. Look for cartridge damage.

2. Use the IBM Leader Pin Reattachment Kit (part number 08L9129) to correctly seat the pin (see “Repositioning a Leader Pin” on page 55). Then, immediately use data recovery procedures to minimize chances of data loss.

Example: Split Cartridge Case

The cartridge’s case is damaged. There is a high possibility of media damage and potential loss. Perform the following steps:

1. Look for cartridge mishandling.

3. Review media-handling procedures.

54 IBM TotalStorage LTO Ultrium 2 Tape Drive

Repositioning or Reattaching a Leader Pin

Attention: Use a repaired tape cartridge only to recover data

and move it to another cartridge. Continued use of a repaired cartridge may void the warranties of the drive and the cartridge.

If the leader pin in your cartridge becomes dislodged from its pin-retaining spring clips or detaches from the tape, you must use the IBM Leader Pin Reattachment Kit (part number 08L9129) to reposition or reattach it. (Do not reattach the pin if you must remove more than 7 meters (23 feet) of leader tape.) The sections that follow describe each procedure.

Repositioning a Leader Pin

A leader pin that is improperly seated inside a cartridge can interfere with the operation of the drive. Figure 16 shows a leader pin in the incorrect 1 and correct 2 positions.

To place the leader pin in its proper position, you will need the following tools:

v Plastic or blunt-end tweezers v Cartridge manual rewind tool (from Leader Pin Reattachment Kit, part number

08L9129)

Figure 16. Leader pin in the incorrect and correct positions. The cartridge door is open and the leader pin is visible inside the cartridge.

Chapter 5. Using the Media 55

To reposition the leader pin, perform the following steps.

1. Slide open the cartridge door (1 in Figure 17) and locate the leader pin 2 (you may need to shake the cartridge gently to roll the pin toward the door).

2. With plastic or blunt-end tweezers, grasp the leader pin and position it in the pin-retaining spring clips 3.

3. Press the leader pin gently into the clips until it snaps into place and is firmly seated. Ensure that there are no gaps in the seam of the cartridge 4.

Attention: If gaps exist, do not continue with this procedure and do not use the cartridge. Instead, contact your OEM Product Application Engineer (PAE).

4. Close the cartridge door.

Figure 17. Placing the dislodged leader pin into the correct position. The cartridge door is open to show the leader pin.

5. To rewind the tape, insert the cartridge manual rewind tool (1 in Figure 18) into the cartridge’s hub 2 and turn it clockwise until the tape becomes taut.

Figure 18. Rewinding the tape into the cartridge

6. Remove the rewind tool by pulling it away from the cartridge.

56 IBM TotalStorage LTO Ultrium 2 Tape Drive

Reattaching a Leader Pin

The first meter of tape in a cartridge is leader tape. Once the leader tape has been removed there is a possibility of tape breakage. After reattaching the leader pin, transfer data from the defective tape cartridge. Do not reuse the defective tape cartridge.

The Leader Pin Reattachment Kit contains three parts: v Leader pin attach tool (see 1 in Figure 19). A plastic brace that holds the

cartridge door open.

v Cartridge manual rewind tool (see 2 in Figure 19). A device that fits into the

cartridge’s hub and lets you wind the tape into and out of the cartridge.

v Pin supplies (see 3 in Figure 19). Leader pins and C-clips.

Attention:

v Use only the IBM Leader Pin Reattachment Kit to reattach the leader pin to the

tape. Other methods of reattaching the pin will damage the tape, the drive, or both.

v Use this procedure on your tape cartridge only when the leader pin detaches

from the magnetic tape and you must copy the cartridge’s data onto another cartridge. Destroy the damaged cartridge after you copy the data. This procedure may affect the performance of the leader pin during threading and unloading operations.

v Touch only the end of the tape. Touching the tape in an area other than the end

can damage the tape’s surface or edges, which may interfere with read or write reliability.

Figure 19. Leader Pin Reattachment Kit

Chapter 5. Using the Media 57

The following procedure describes how to reattach a leader pin.

To reattach a leader pin by using the IBM Leader Pin Reattachment Kit:

1. Attach the leader pin attach tool (1 in Figure 20) to the cartridge 2 so that the tool’s hook 3 latches into the cartridge’s door 4. Pull the tool back to hold the door open, then slide the tool onto the cartridge. Open the tool’s pivot arm 5.

Figure 20. Attaching the leader pin attach tool to the cartridge. To hold the cartridge door open, hook the tool into the door and pull the tool back.

58 IBM TotalStorage LTO Ultrium 2 Tape Drive

2. To find the end of the tape inside the cartridge, attach the cartridge manual rewind tool (1 in Figure 21) to the cartridge’s hub 2 by fitting the tool’s teeth between the teeth of the hub. Turn the tool clockwise until you see the end of the tape inside the cartridge. Then, slowly turn the rewind tool counterclockwise to bring the tape edge toward the cartridge door 3.

3. Continue to turn the rewind tool counterclockwise until approximately 12.7 cm (5 in.) of tape hangs from the cartridge door. If necessary, grasp the tape and pull gently to unwind it from the cartridge.

4. Remove the rewind tool by pulling it away from the cartridge. Set the tool and the cartridge aside.

Figure 21. Winding the tape out of the cartridge. Turn the cartridge manual rewind tool clockwise to see the end of the tape, then turn it counterclockwise to bring the tape to the cartridge door.

5. On the leader pin (1 in Figure 22), locate the open side of the C-clip 2. The C-clip is a small black part that secures the tape 3 to the pin.

6. Remove the C-clip from the leader pin by using your fingers to push the clip away from the pin. Set the pin aside and discard the clip.

Figure 22. Removing the C-clip from the leader pin. Use your fingers to push the C-clip from the leader pin.

Chapter 5. Using the Media 59

7. Position the tape in the alignment groove of the leader pin attach tool (see 1 in Figure 23).

8. Place a new C-clip into the retention groove 2 (Figure 23) on the leader pin attachment tool and make sure that the clip’s open side faces up.

9. Place the leader pin (from step 6 on page 59) into the cavity 3 (Figure 23) of the leader pin attach tool.

Attention: To prevent the leader pin from rolling into the cartridge, in the following step use care when folding the tape over the pin.

10. Fold the tape over the leader pin and hold it with your fingers (see Figure 23).

Note: Use care to ensure that the tape is centered over the leader pin. Failure

to properly center the tape on the pin will cause the repaired cartridge to fail. When the tape is properly centered, a 0.25-mm (0.01-in.) gap exists on both sides of the pin.

Figure 23. Attaching the leader pin to the tape

A67E0037

11. Close the pivot arm 4 of the leader pin attach tool by swinging it over the leader pin so that the C-clip snaps onto the pin and the tape.

12. Swing the pivot arm open and trim the excess tape 5 so that it is flush with

the reattached leader pin 6.

60 IBM TotalStorage LTO Ultrium 2 Tape Drive

13. Use your fingers to remove the leader pin from the cavity 3 in the leader pin attach tool.

14. Use the cartridge manual rewind tool to wind the tape back into the cartridge (wind the tape clockwise). Ensure that the leader pin is latched by the pin-retaining spring clips on each end of the leader pin.

15. Remove the rewind tool.

16. Remove the leader pin attach tool by lifting its end up and away from the cartridge.

Attention: Use a repaired tape cartridge only to recover data and move it to another cartridge. Continued use of a repaired cartridge may void the warranties of the drive and the cartridge.

Chapter 5. Using the Media 61

Environmental and Shipping Specifications for Tape Cartridges

Before you use a tape cartridge, acclimate it to the operating environment for 24 hours or the time necessary to prevent condensation in the drive (the time will vary, depending on the environmental extremes to which the drive was exposed).

The best storage container for the cartridges (until they are opened) is the original shipping container. The plastic wrapping prevents dirt from accumulating on the cartridges and partially protects them from humidity changes.

When you ship a cartridge, place it in its jewel case or in a sealed, moisture-proof bag to protect it from moisture, contaminants, and physical damage. Ship the cartridge in a shipping container that has enough packing material to cushion the cartridge and prevent it from moving within the container.

Disposing of Tape Cartridges

Under the current rules of the U.S. Environmental Protection Agency (EPA), regulation 40CFR261, the LTO Ultrium Tape Cartridge is classified as non-hazardous waste. As such, it may be disposed of in the same way as normal office trash. These regulations are amended from time to time, and you should review them at the time of disposal.

If your local, state, country (non-U.S.A.), or regional regulations are more restrictive than EPA 40CFR261, you must review them before you dispose of a cartridge. Contact your account representative for information about the materials that are in the cartridge.

If a tape cartridge must be disposed of in a secure manner, you can erase the data on the cartridge by using a high-energy AC degausser (use a minimum of 1200 oersted peak field over the entire space that the cartridge occupies). Degaussing makes the cartridge unusable.

If you burn the cartridge and tape, ensure that the incineration complies with all applicable regulations.

Descriptions and Corrective Actions for Errors and Messages

Table 15 gives descriptions of the errors and messages that pertain to the Ultrium 2 Tape Drive, and tells what to do when you receive them.

Attention: If the tape drive detects a permanent error and displays an error code other than 0, it automatically performs a drive dump. If you force a drive dump, the existing dump will be overwritten and data will be lost. After you force a drive dump, do not turn off the power to the tape drive or you may lose the dump data.

Table 15. Codes for error conditions and informational messages for the IBM TotalStorage LTO Ultrium 2 Tape Drive. The single-character display clears if you power-off the drive.

Code Cause and Action

0 No error occurred and no action is required. This code displays:

v When power is cycled (turned off, then on) to the tape drive. v When diagnostics have finished running and no error occurred.

Note: The single-character display is blank during normal operation of the tape drive.

1 Cooling problem. The tape drive detected that the recommended operating temperature was

exceeded. Perform the following action:

1. If a fan is present in the enclosure, ensure that it is rotating and is quiet. If not, replace the fan (for instructions about replacing the fan, see your enclosure’s documentation).

2. Remove any blockage that prevents air from flowing freely through the tape drive.

3. Ensure that the operating temperature and airflow is within the specified range (see Chapter 2, “Specifications” on page 11).

4. If the operating temperature is within the specified range and the problem persists, replace the tape drive.

The error code clears when you power-off the tape drive or place it in maintenance mode.

2 Power problem. The tape drive detected that the externally supplied power is either approaching

the specified voltage limits (the drive is still operating) or is outside the specified voltage limits (the drive is not operating). Perform the following action:

1. Ensure that the power connector is properly seated.

2. Ensure that the proper dc voltages are being applied within the tolerances allowed (see Chapter 2, “Specifications” on page 11).

3. If the proper voltages are being applied but the problem persists, replace the tape drive.

Code Cause and Action

6 Tape drive or media error. The drive determined that an error occurred, but it cannot isolate the

error to faulty hardware or to the tape cartridge. Perform the following action:

For Problems with Writing Data:

If the problem occurred while the drive was writing data to the tape, and if you know the volume serial number (located on the cartridge label) of the tape cartridge loaded in the drive when the problem occurred, retry the operation with a different cartridge: v If the operation succeeds, the original cartridge was defective. Copy data from the defective

cartridge and discard it.

v If the operation fails and another drive is available, insert the cartridge into the other drive and

retry the operation.

– If the operation fails, discard the defective cartridge. – If the operation succeeds, insert a scratch cartridge into the first drive and run the tape drive

diagnostics (see Function Code 1 in Table 9 on page 36).

- If the diagnostics fail, replace the drive.

- If the diagnostics succeed, the error was temporary.

v If the operation fails and another drive is not available, insert a scratch cartridge into the drive

and run the tape drive diagnostics (see Function Code 1 in Table 9 on page 36).

– If the diagnostics fail, replace the drive. – If the diagnostics succeed, discard the cartridge.

If the problem occurs with multiple tape cartridges or if you do not know the tape cartridge’s volume serial number, run the tape drive diagnostics (see Function Code 1 in Table 9 on page 36):

v If the diagnostics fail, replace the tape drive. v If the diagnostics succeed, run the Test Head diagnostic (see Function Code H in Table 9 on

page 36).

– If the Test Head diagnostic fails, replace the tape drive. – If the Test Head diagnostic succeeds, replace the cartridges that caused the problem.

The error code clears when you remove the tape cartridge or place the drive in maintenance mode.

For Problems with Reading Data:

If the problem occurred while the drive was reading data from the tape, and if you know the volume serial number of the tape cartridge, perform one of the following procedures: v If another drive is available, insert the cartridge into the other drive and retry the operation:

– If the operation fails, discard the defective cartridge. – If the operation succeeds, insert a scratch cartridge into the first drive and run the tape drive

diagnostics (see Function Code 1 in Table 9 on page 36):

- If the diagnostics fail, replace the drive.

- If the diagnostics succeed, the error was temporary.

v If another drive is not available, insert a scratch cartridge into the drive and run the tape drive

diagnostics (see Function Code 1 in Table 9 on page 36):

– If the diagnostics fail, replace the drive. – If the diagnostics succeed, discard the cartridge.

If the problem occurs with multiple tape cartridges or if you do not know the tape cartridge’s volume serial number, run the tape drive diagnostics (see Function Code 1 in Table 9 on page 36):

v If the diagnostics fail, replace the tape drive. v If the diagnostics succeed, run the Test Head diagnostic (see Function Code H in Table 9 on

page 36).

– If the Test Head diagnostic fails, replace the tape drive. – If the Test Head diagnostic succeeds, replace the cartridges that caused the problem.

The error code clears when you remove the tape cartridge or place the drive in maintenance mode.

Table 15. Codes for error conditions and informational messages for the IBM TotalStorage LTO Ultrium 2 Tape Drive (continued). The single-character display clears if you power-off the drive.

Code Cause and Action

7 A high probability of media error. The tape drive determined that an error occurred because of a

faulty tape cartridge. Try another tape cartridge. If the problem occurs with multiple tape cartridges, see “Resolving Media-Related Problems” on page 82.

The error code clears when you remove the tape cartridge or place the drive in maintenance mode.

8 For SCSI drive:

Tape drive or SCSI bus failure. The tape drive determined that a failure occurred in the tape drive’s hardware or in the SCSI bus. See “Fixing SCSI Bus Errors” on page 77. The error code clears 10 seconds after the drive detected the error or when you place the drive in maintenance mode.

For Fibre Channel drive:

Tape drive or Fibre Channel failure. The tape drive determined that a failure occurred in the tape drive’s hardware or in the Fibre Channel. It detects light through the fiber cable but cannot perform data communication properly. The length of the cable between the devices may exceed 500 m (1640 ft). See “Fixing Fibre Channel Errors” on page 79. The error code clears when the drive detects light and can communicate, or when you place the drive in maintenance mode.

9 Tape drive or LDI (RS-422) error. The tape drive determined that a failure occurred in the tape

drive hardware or in the LDI (RS-422) connection. Run the LDI or RS-422 wrap test (see Function Code 7 in Table 9 on page 36):

v If the diagnostic fails, replace the tape drive. v If the diagnostic runs successfully, the problem is with the enclosure or the cable to the

enclosure. Refer to your enclosure’s documentation.

The error code clears when you place the drive in maintenance mode.

o, c, b, or h No error or message assigned. There may be a problem with the single-character display. Turn the

power off, then on and determine whether all segments on the single-character display are lit. If so, you may have a down-level version of both your enclosure’s firmware and documentation (the documentation may not describe all of the available error codes). Refer to the latest version of the firmware or documentation.

A Tape drive hardware problem. The tape drive determined that a problem occurred which degraded

the operation of the tape drive, but it did not restrict continued use. If the problem persists, replace the tape drive. The drive is usable, though the single-character display continues to indicate an error and the status light flashes amber.

The error code may clear when you cycle power to the tape drive or place it in maintenance mode. B No error or message is assigned. See error code 8 in this table. C The tape drive needs to be cleaned. Clean the tape drive. See “Cleaning the Drive Head” on

page 35.

The error code clears when you clean the tape drive or place it in maintenance mode. d Fibre Channel AL_PA conflict. More than one device has the same address. Each device must

have its own unique AL_PA address. See “Setting the Arbitrated Loop Physical Address (Fibre

Channel Drive Only)” on page 19. D No error or message assigned. See error code 0 in this table. E Informational message. The tape drive’s Fibre Channel port has been placed offline by another

device or by an operator. This code is set when the Offline command is received from another

device on the Fibre Channel interface. Determine why the device at the other end of the Fibre

Channel (the server, switch, or other device) placed the drive offline.

The drive is placed online when it receives the Online command from the Fibre Channel interface.

After a reset, the drive comes online.

Table 15. Codes for error conditions and informational messages for the IBM TotalStorage LTO Ultrium 2 Tape Drive (continued). The single-character display clears if you power-off the drive.

Code Cause and Action

F The tape drive determined that no light is being received over the Fibre Channel. See “Fixing Fibre

Channel Errors” on page 79.

The error code clears when the drive detects light or when you place the drive in maintenance mode.

Using Sense Data

When a tape drive encounters an error, it makes sense data available. You can use IBM device drivers to examine the sense data and determine errors. Instructions for downloading, installing, and properly configuring the IBM device drivers are available in the IBM Ultrium Device Drivers Installation and User’s Guide. The IBM device drivers may conflict with some commercial software applications unless properly configured. To avoid conflicts on Windows operating systems, refer to your device driver’s procedures for setting the driver to manual startup mode. For applications that use Open Systems device drivers that are provided by IBM (for example, AIX, Linux, Sun Solaris, HP-UX, Windows/NT, and Windows 2000), the IBM Ultrium Device Drivers Installation and User’s Guide contains information about how to obtain sense data after an error has occurred.

If your application uses other device drivers, see the appropriate documentation for those drivers to obtain the sense data.

Raw sense data (as returned from the Ultrium 2 Tape Drive) is documented in the IBM TotalStorage LTO Ultrium Tape Drive SCSI Reference.

In addition to device drivers, other methods exist for obtaining sense data and error information. The sections that follow describe alternatives for gathering such information from the IBM AS/400, Eserver iSeries, RS/6000, and Eserver pSeries servers.

Obtaining Error Information from the AS/400 or iSeries with RISC Processor

For OS/400, sense data is provided by the System Service Tools application. To obtain error information from the AS/400 or iSeries by using the tool:

1. On the command entry line of the AS/400 Main Menu, type STRSST (Start System Service Tools) and press Enter.

2. Select Start a service tool.

3. Select Product activity log.

4. Select Analyze log.

5. On the Select System Data menu, select the Magnetic media option then specify the time period for searching the error log.

6. On the Select Analysis Report Options menu, specify a Device selection of 3580 and press Enter. Leave all other options at their default values.

7. On the Log Analysis Report menu, select the Display report option to display the desired error log. Figure 24 on page 72 shows a sample error log.

Obtaining a Drive Dump

You can obtain a drive dump by selecting a function code on the IBM TotalStorage LTO Ultrium 2 Tape Drive or by using a device driver utility (or a system tool) on the server. The sections that follow describe each method.

Using the Drive to Obtain a Dump

To obtain a drive dump directly from the IBM TotalStorage LTO Ultrium 2 Tape Drive:

1. Make sure that no cartridge is in the drive.

2. Within a 1.5-second interval, press the unload button three times. The status light becomes solid amber, which means that the drive is in maintenance mode.

3. Press the unload button once per 1.5 seconds until 5 appears in the single-character display.

4. To select the function, press and hold the unload button for 3 seconds. After you release the button, C flashes. Within 60 seconds, insert a scratch data cartridge that is not write-protected. After you insert the cartridge, 5 flashes and the drive writes the dump data to the scratch tape. When the function is complete, the drive rewinds and unloads the tape.

5. Insert the tape into a drive.

6. From the server, issue the SCSI READ command to read the dump from the tape to a file or electronic image (you may need to issue the command several times to read the complete dump).

7. To determine where to send the file for analysis, contact your OEM Product Application Engineer (PAE).

Using a Device Driver Utility to Obtain a Dump

To obtain a drive dump by using a device driver utility, determine whether your server is installed with a utility that can read files from the server’s memory. If it is, use that utility to obtain the drive dump.

For information about using IBM’s utility programs to obtain drive dumps, see the IBM Ultrium Device Drivers Installation and User’s Guide.

To determine where to send a file that contains a drive dump to be analyzed, contact your OEM Product Application Engineer (PAE).

Chapter 6. Resolving Problems 75

Viewing the Drive Error Log

The Ultrium 2 Tape Drive keeps an error log that you can use to identify and correct errors. The log contains the 10 most recent error codes, which appear (one at a time) on the single-character display.

To view the drive error log:

1. Make sure that no cartridge is in the drive.

2. Within a 1.5-second interval press the unload button three times. The status light becomes solid amber, which means that the drive is in maintenance mode.

3. Press the unload button once per 1.5 seconds until 9 appears in the single-character display.

4. Press and hold the unload button for 3 seconds to view the most recent error code.

5. Refer to Table 15 on page 67 to determine the meaning of the code and the action to take.

6. Press the unload button to view the next error code. (The codes are ordered; the most recent is presented first and the oldest (tenth) is presented last.)

7. Continue to press the unload button until the 10 error codes have been displayed. After you display the tenth error code, the drive automatically exits maintenance mode.

To redisplay the error codes, repeat steps 1 through 7.

76 IBM TotalStorage LTO Ultrium 2 Tape Drive

Resolving Problems Reported by the Server

The procedure for fixing SCSI bus or Fibre Channel errors varies, depending on whether the error is consistent or intermittent, and whether your configuration contains single or multiple Ultrium 2 Tape Drives. The sections that follow describe how to fix each type of error.

Fixing SCSI Bus Errors

Note: If you are using a Storage Area Network (SAN) Data Gateway to convert a

drive with a SCSI interface to a Fibre Channel interface, ensure that the problem is occurring between the SAN Data Gateway and the drive by running the SCSI wrap test on the drive and running the SCSI loopback test on the SAN Data Gateway. (To run the SCSI wrap test, see Function Code 6 in Table 9 on page 36; to run the SCSI loopback test, refer to the section about that test in the IBM Storage Area Network Gateway Module Setup, Operator, and Service Guide.) If you are using a Fibre Channel drive and are having problems, see “Fixing Fibre Channel Errors” on page 79.

Fixing a Consistent Error with a Single Drive on a SCSI Bus

1. Ensure that the power is on to the Ultrium 2 Tape Drive.

2. Ensure that the tape drive’s SCSI address is the same as the SCSI address assigned by the server.

3. Run the SCSI wrap test (see Function Code 6 in Table 9 on page 36). v If the test runs successfully, replace the SCSI terminator first, then the SCSI

cable and the interposer (if installed). Repeat the operation that caused the error. If you replaced the SCSI terminator or SCSI cable and the problem persists, the fault is with the server’s hardware or software. To isolate the cause of the failure, refer to the server’s service documentation.

v If the test fails, replace the tape drive (see “Removing a SCSI Tape Drive

from an Enclosure” on page 83).

Fixing a Consistent Error with Multiple Drives on a SCSI Bus

When a consistent error occurs in a configuration that has multiple tape drives on the SCSI bus, you must determine if the problem exists with more than one tape drive. If the problem is with all of the devices on the SCSI bus, the bus is stuck in a SCSI phase and cannot change to another phase or the SCSI cable from the server to the first device is defective.

1. Ensure that the SCSI cable from the server to the first device is connected.

2. Disconnect all but the first tape drive on the SCSI bus. Move the terminator to the first SCSI device.

3. Run a device driver utility (such as IBM’s ntutil or tapeutil) to determine whether the error will occur.

v If the error occurs, run the SCSI wrap test on the first tape drive (see

Function Code 6 in Table 9 on page 36). – If the test runs successfully, replace the SCSI terminator first, then the

SCSI cable and the interposer (if installed) to the first tape drive. Repeat the operation that caused the error. If you replaced the SCSI terminator or SCSI cable and the problem persists, the fault is with the server’s hardware or software. To isolate the cause of the failure, refer to the server’s service documentation.

– If the test fails, replace the tape drive (see “Removing a SCSI Tape Drive

from an Enclosure” on page 83).

Chapter 6. Resolving Problems 77

v If the error does not occur, connect one tape drive at a time back to the bus

and repeat step 3 for each tape drive until you can identify which drive is defective.

Note: Ensure that the SCSI terminator is always on the last tape drive on the

SCSI bus.

4. Determine if the problem is with only one tape drive or with two or more tape drives.

v If the problem is with only one tape drive, run the SCSI wrap test on that tape

drive (see Function Code 6 in Table 9 on page 36). – If the test runs successfully, replace the SCSI terminator first, then the

SCSI cable to that tape drive and interposer (if installed).

– If the test fails, replace the tape drive (see “Removing a SCSI Tape Drive

from an Enclosure” on page 83).

v If the problem is with two or more tape drives, locate the first tape drive that

has the error and replace the SCSI cable that connects the tape drive and the interposer (if installed).

Fixing an Intermittent Error with a Single Drive on a SCSI Bus

1. Replace the SCSI terminator on the tape drive.

2. Run the operation that caused the error. If the problem persists, the problem may be with the cable.

3. Isolate which cable is causing the problem by replacing one cable at a time and running the operation that caused the error after each replacement. If the problem persists after all cables have been replaced, the problem may be with the Ultrium 2 Tape Drive.

4. Replace the tape drive (see “Removing a SCSI Tape Drive from an Enclosure”

on page 83). If the problem persists, the problem is with your server. Consult

your server’s documentation.

Fixing an Intermittent Error with Multiples Drives on a SCSI Bus

Refer to the server’s error logs to determine which tape drive is the source of the problem:

v If only one tape drive is reporting a SCSI failure, replace that tape drive (see

“Removing a SCSI Tape Drive from an Enclosure” on page 83).

v If multiple tape drives are reporting SCSI failures, the problem may be with the

terminator or the SCSI cables: – Replace the terminator and run the operation that caused the error. If the

problem persists, the problem may be with the cables.

– Isolate which cable is causing the problem by replacing one cable at a time

and run the operation that caused the error after each replacement.

78 IBM TotalStorage LTO Ultrium 2 Tape Drive

Fixing Fibre Channel Errors

If you are connected to a Fibre Channel Storage Area Network (SAN) by using a SAN Data Gateway, use the IBM Storage Area Network Gateway Module Setup, Operator, and Service Guide to determine whether the problem is occurring between the drive and the SAN Data Gateway. If you are using a SCSI drive and are having SCSI problems, see “Fixing SCSI Bus Errors” on page 77.

Starting Problem Determination

Before starting the problem determination, perform the following steps:

1. Determine the type of Fibre Channel topology that you are using (see page 6). Ensure that the drive and the port to which it is attached are configured in compatible topologies.

2. Using this guide or the service guides of associated switch, hub, or fiber products, try to determine where the problem exists (whether in the drive, cable, or the device to which the drive and cable attach).

3. Ensure that the configuration and software levels are supported (see “Fibre Channel Attachment” on page 6).

4. Ensure that the Fibre Channel cables are installed correctly. Refer to the appropriate steps in Chapter 3, “Installing the Tape Drive” on page 13.

5. Go to one of the following procedures:

v “Fixing a Consistent Error with a Single Drive on a Fibre Channel Loop” v “Fixing a Consistent Error with Multiple Drives on a Fibre Channel Loop” on

page 80

v “Fixing a Consistent Error in a Point-to-Point Topology” on page 80 v “Fixing Intermittent Fibre Channel Errors” on page 81

Fixing a Consistent Error with a Single Drive on a Fibre Channel Loop

1. Ensure that the tape drive is powered on.

2. Verify that the tape drive’s serial number is the same as the drive serial number that the server program is using.

3. Ensure that the drive’s Fibre Channel AL_PA is set correctly, that it is on the loop, and that it is not being used by another device (see “Setting the Arbitrated Loop Physical Address (Fibre Channel Drive Only)” on page 19).

7. Obtain all errors reported by the drive to the server (see “Using Sense Data” on page 71), then contact your OEM Product Application Engineer (PAE) for error analysis.

Chapter 6. Resolving Problems 81

Resolving Media-Related Problems

To resolve problems that are related to media, the Ultrium 2 Tape Drive’s firmware includes:

v Test Cartridge & Media diagnostic that verifies whether a suspect cartridge and

its magnetic tape are acceptable for use.

v Statistical Analysis and Reporting System (SARS) to assist in isolating failures

between media and hardware. To determine the cause of failure, SARS uses the cartridge performance history that is saved in the cartridge memory (CM) and the drive performance history that is kept in the drive’s flash erasable programmable read-only memory (EPROM). Any failures that SARS detects are reported as TapeAlert flags on the server (see Appendix B, “TapeAlert Flags” on page 97).

Attention: If you insert the IBM LTO Ultrium Data Cartridge into another manufacturer’s tape drive, the SARS data in the cartridge memory may become lost or invalid.

If you encounter a media-related problem, use the following procedure:

Attention: When you run the Test Cartridge & Media diagnostic, data on the suspect tape is overwritten. Use only a scratch data cartridge to run the test.

1. If possible, run the tape cartridge in a different tape drive. If the operation in the other tape drive fails and 6 or 7 displays, replace the media. If the operation succeeds, run the Test Cartridge & Media diagnostic (see Function Code E in Table 9 on page 36).

2. If the Test Cartridge & Media diagnostic fails, replace the media. If it runs successfully, clean the tape drive and run the tape drive diagnostics (see “Cleaning the Drive Head” on page 35 and Function Code 1 in Table 9 on page 36).

3. If the tape drive diagnostics fail, replace the tape drive. If the tape drive diagnostics run successfully, perform the operation that produced the initial media error.

Manually Removing a Tape Cartridge

If problem-determination procedures identify the Ultrium 2 Tape Drive as the source of a problem, you can optionally perform one of the following:

v Replace the entire unit. For more information, contact your OEM Product

Application Engineer (PAE).

v Manually remove the cartridge (see “Removing the Cartridge”). v If you are unable to manually remove the cartridge, contact trained service

personnel for assistance. Refer the service personnel to the instructions in “Fixing an Internal Jam” on page 88.

Attention: If you are not a trained service person, do not attempt to open the drive for repairs. Attempting a repair other than the manual removal of a tape cartridge will void your warranty.

Removing the Cartridge

If a tape cartridge fails to eject from the Ultrium 2 Tape Drive, you can manually remove the cartridge. The following tools are required for the procedure:

v 2.5-mm allen wrench v Small-blade screwdriver or potentiometer-setting tool v 2-mm hex wrench v #3 Phillips screwdriver v Needle-nose pliers v Flashlight (optional)

Attention: Before performing this procedure, note the following:

v Ensure that you have attempted all normal methods of removing the tape

cartridge from the drive. Refer to “Removing a Tape Cartridge” on page 35 and the troubleshooting tips in Table 13 on page 65.

v This procedure may damage the stuck tape cartridge. If you use this procedure,

copy the data from the stuck cartridge to another cartridge. If you choose to reuse the stuck cartridge, refer to the instructions in “Repositioning or Reattaching a Leader Pin” on page 55. If you believe the cartridge has been damaged, replace it.

v Do not use a power screwdriver to perform this procedure because it can destroy

the tape.

v Never touch the head or electronic components within the drive. Touching may

cause contamination or damage by electrostatic discharge.

Chapter 7. Servicing 85

To manually remove a tape cartridge, perform the following steps:

1. Place the drive so that the front faces you, then tilt it on its left side (see Figure 30).

2. Locate the access hole at the bottom of the unit (see 1 in Figure 30).

3. Insert a 2.5-mm allen wrench into the access hole and position the wrench so that it is seated in the screw of the supply reel motor.

4. Push open the door of the tape load compartment and locate the flag 2 on the drive’s takeup reel.

Figure 30. Determining whether the tape is broken

Attention: In the following step, rotate the allen wrench clockwise, not counterclockwise. A counterclockwise motion may damage the tape.

5. To determine whether the tape is broken, watch the flag 2 on the drive’s takeup reel while you rotate the allen wrench 1 clockwise (do not let the wrench move counterclockwise): v If you feel resistance to the allen wrench while attempting to turn the supply

reel motor screw clockwise, go to step 7 on page 87.

v If the takeup reel turns when you rotate the supply reel motor screw

clockwise with the allen wrench, the tape is not broken. Go to step 6 on page 87.

v If the takeup reel does not turn when you rotate the supply reel motor screw

clockwise with the allen wrench and if supply reel motor screw rotates freely, the tape is broken. You must determine the location of the leader block. To do so, insert a small-blade screwdriver or potentiometer-setting tool into the access hole for the loader motor gear 3. Rotate the screwdriver counterclockwise. You may have to rotate for a lengthy period: – If the cartridge moves up, the tape is completely in the cartridge and the

leader block is in the home position. Continue rotating the screwdriver until the cartridge ejects. Remove the cartridge.

– If you feel resistance and the cartridge does not move up, the leader

block is not in the home position. Go to “Fixing an Internal Jam” on page 88.

86 IBM TotalStorage LTO Ultrium 2 Tape Drive

6. Continue to rotate the allen wrench until you feel resistance. The tape has been rewound as far as it can go without unthreading.

Note: The number of required rotations depends on where the beginning of

the tape is on the cartridge’s takeup reel. You may have to rotate the allen wrench for a lengthy period.

7. With the allen wrench still inserted into the bottom access hole, insert a small-blade screwdriver or potentiometer-setting tool into the access hole for the loader motor gear 3.

8. While keeping torque on the supply reel motor screw and rotating the allen wrench 1 clockwise, rotate the loader motor gear with the small-blade screwdriver 3 counterclockwise (see arrow). As you rotate the screwdriver, the allen wrench moves slightly.

9. With the small-blade screwdriver, continue to rotate the loader motor gear in the unload direction (counterclockwise):

v If you feel no resistance to the allen wrench and the cartridge slowly moves

up and out of the tape load compartment to the fully ejected position, the procedure was successful. Remove the small-blade screwdriver and go to step 10.

v If you feel resistance to the allen wrench and the cartridge does not move,

the loader mechanism is jammed or the leader block is not at the home position. Remove the small-blade screwdriver and go to “Fixing an Internal Jam” on page 88.

10. Remove the tape cartridge.

11. To ensure that the drive operates properly, refer to page 36 and select Function Code 1 - Run Tape Drive Diagnostics.

After you remove the stuck tape cartridge, copy the data on the tape to another tape. Then, if appropriate, return the stuck tape cartridge in its original packaging or in the packaging from its replacement to your reseller. If the leader pin detached from the tape in the cartridge, go to “Repositioning or Reattaching a Leader Pin” on page 55.

Chapter 7. Servicing 87
