viii IBM Ultrium Internal Tape Drive

Chapter 1. Introduction

The IBM Ultrium Internal Tape Drive Models T200 and T200F are high-performance, high-capacity data-storage devices that can be integrated into an enclosure, such as a desktop unit, tape cartridge autoloader, or tape library. The tape drives are designed to perform unattended backups, as well as retrieve and archive files. Table 1 outlines the features of the Models T200 and T200F. Figure 1 is a front view of the drive with and without a bezel.

The Ultrium Internal Tape Drive uses a data compression algorithm known as LTO-DC (LTO Data Compression). A key difference between LTO-DC and previous compression algorithms is that record boundaries and file marks are encoded as control symbols in LTO-DC. LTO-DC detects them, but it will not recompress and

| | |

test them. Another difference is that LTO-DC allows switching between compression and no compression within the data stream. This feature prevents the data from expanding when the drive compresses random or encrypted data.

IBM offers device drivers for the Ultrium Tape Drive. Device drivers enable the drive

1. 1 GB = one gigabyte or 1 000 000 000 bytes

2. 1 MB = one megabyte or 1 000 000 bytes

to interact with a variety of servers. To properly install an IBM device driver (if

required), refer to the IBM Ultrium Device Drivers Installation and User’s Guide. For applications that use other device drivers, see the application’s documentation to determine which drivers to use.

In addition to using IBM tape cartridges with up to 100 GB capacity, the Ultrium Tape Drive also offers read/write capability for certified LTO Ultrium tape cartridges that have capacities of 50 GB, 30 GB, and 10 GB.

The Ultrium Tape Drive records by using a linear, serpentine recording method on 1/2-inch, magnetic tape.

To order a cable, see “Appendix A. Tools and Supplies” on page 81.

Address Assignments

For enhanced functions in automated library systems, the SCSI drive contains an

2 IBM Ultrium Internal Tape Drive

RS-422 interface. If the drive is connected to a library, its SCSI address can be set through the RS-422 interface.

Another option to setting the SCSI address is by attaching jumpers to the SCSI ID connector (see “Step 4. Set the SCSI ID (SCSI Drive Only)” on page 14).

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

| |

Attaching a drive to an active SCSI bus is supported. 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

| |

Fibre Channel Attachment

| |

| | |

The Ultrium Tape Drive Model T200F 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. You can attach the Fibre Channel port to the following servers and SAN components. For additional information about the Fibre Channel connectivity, visit the web at http://www.ibm.com/storage/storagesmart/lto. To obtain information about adapters and operating systems, visit the web at http://www.storage.ibm.com/lto.

Chapter 1. Introduction 3

Physical Characteristics of the Fibre Channel Interface

| | | | |

The Ultrium Tape Drive Model T200F attaches to Open Systems servers by using short-wave, multimode fiber optic cables. All cables feature SC-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). All cables are for field or plant installation, and are available in the following lengths:

v 0.5 m (1.6 ft) v 13 m (43 ft) v 25 m (82 ft) v 61 m (200 ft) v Custom-length fiber cable

| | | |

You can order fiber cables for specific lengths (other than lengths with feature codes) by using part number 54G3391. The maximum length is 500 m (1640 ft). Cable length is measured from the drive’s Fibre Channel port. To order a cable, see “Appendix A. Tools and Supplies” on page 81.

Supported Topologies

The drive supports Two-node Arbitrated Loop and Two-node Switched Fabric Loop topologies.

Two-node Arbitrated Loop

The drive supports the arbitrated loop topology, but only two nodes are supported on a loop.

Two-node Switched Fabric Loop

Two or more Fibre Channel end points interconnect through a switch. These switches must have loop-attachment capability. Two nodes are supported on each fabric loop.

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 3 on page 17 and Table 4 on page 18.) 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 11). The pin configuration for soft and hard addressing is defined in “Step 6. Set the Arbitrated Loop Physical Address (Fibre Channel Drive Only)” on page 15.

4 IBM Ultrium Internal Tape Drive

World Wide Names

| |

| | | | |

Each Ultrium Tape Drive has an 8-byte World Wide Name that is assigned by IBM Manufacturing. The World Wide Name identifies physical drive ports. An enclosure queries the World Wide Name through the RS-422 interface; a server queries the Name through the Fibre Channel interface. The Ultrium Tape Drive reports the World Wide Name to switches. You can use the World Wide Name to uniquely identify the drive on a SAN.

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.

Attention:

To avoid static electricity damage when you handle the Ultrium Internal Tape

Drive, use the following precautions:

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

you.

v Always handle the Ultrium Tape Drive carefully. Handle adapters by the

edges. Never touch exposed circuitry.

v Prevent others from touching the Ultrium Tape Drive.

v Before you unpack and install the Ultrium 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 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 Tape Drive on the cover of the enclosure or on any

other metal surface.

The steps that follow describe how to install the Ultrium Tape Drive. 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 Tape Drive into an enclosure, refer to “Rear View of the SCSI Drive” on page 10 or “Rear View of the Fibre Channel Drive” on page 11.

Step 1. Unpack the Drive

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

Step 2. Power-off the Enclosure (Optional)

It is recommended (but not required) that you power-off the enclosure when you install or remove the tape drive.

Step 3. Install the Cooling Fan Assembly (Optional)

The Ultrium Tape Drive’s circuits require cooling. The drive is designed to move air

across the circuits, with air entry at the lower front of the drive (the tape path and drive head are protected from airflow and associated debris).

If the cooling fan is not attached and the temperature inside your enclosure does not meet requirements, install the IBM cooling fan assembly (see the temperature requirements in Table 2 on page 7). The procedure for installing the fan varies, depending on whether your drive uses a SCSI or Fibre Channel interface. The sections that follow describe each procedure.

Chapter 3. Installing 11

Installing the Cooling Fan onto a SCSI Drive

To install the optional cooling fan assembly onto an Ultrium Tape Drive that uses a SCSI interface:

1. Remove and discard the two cover screws from the rear of the Ultrium Tape

| | | | | | | |

Drive (see 1 in Figure 4). Use a Phillips screwdriver to remove the screws.

2. Position the fan shroud 2 at the rear of the drive and align its top with the top of the drive.

3. Attach the fan shroud to the rear of the drive by securing the two captured screws 3 with a Phillips screwdriver.

4. Connect the SCSI bus cable 4 to the connector at the rear of the SCSI drive.

5. Attach one end of the Y-cable 5 to the drive’s power connector.

6. Attach the fan cover assembly 6 to the fan shroud 2 by securing four screws 7 with a Phillips screwdriver.

7. Connect the other end of the Y-cable 8 to the fan assembly’s power connector 9.

8. Connect the Y-cable 10 to the power supply in the enclosure.

Figure 5. Installing the Cooling Fan Assembly onto a Fibre Channel Drive

Chapter 3. Installing 13

Step 4. Set the SCSI ID (SCSI Drive Only)

Notes:

1. When setting the SCSI ID, use the 2-mm jumpers that come attached to the Ultrium Tape Drive’s SCSI ID connector (four jumpers are shipped on the connector; an additional jumper is unattached, but included in the ship group). To order additional jumpers, contact your IBM marketing representative.

| | | |

2. If your enclosure uses a SCSI ID switch (rather than jumpers), do not perform the following procedure. Instead, remove the jumpers from the Ultrium Tape Drive and connect the switch (for instructions, refer to your enclosure’s documentation).

3. If you are installing the Ultrium Tape Drive into a tape library, make sure that the drive’s SCSI ID is set at 15 (see settings below). The library may issue a command to the tape drive to set the SCSI ID via the RS-422 interface.

To set the SCSI ID:

1. Locate the SCSI ID connector (see 2 in Figure 2 on page 10).

2. Before attaching the SCSI bus cable to the server, decide the number of the SCSI ID that you want. Make sure that the ID is not being used by another device.

3. Referring to the following figure, 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).

14 IBM Ultrium Internal Tape Drive

Step 5. Terminate the Drive and Supply TERMPOWER (SCSI Drive Only)

If the tape drive is the last device on the SCSI bus, you must terminate the bus

outside the enclosure or internally at the SCSI ID connector (see 2 in Figure 2 on page 10).

To terminate the bus internally, locate one of the five jumpers shipped with the Ultrium 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.

To supply TERMPOWER to the bus, locate one of the five jumpers shipped with the Ultrium 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.

A67E0049

Step 6. Set 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 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 15

Setting the Loop ID to Provide Status About the Loop

| |

| | | | | | |

| |

If Feature Switch 3 on the Ultrium 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). If the drive does not detect light on the Fibre Channel connector or has not completed the Loop Initialization Protocol (LIP), pin 5 will be off. If the drive detects light and successfully completes the LIP process, the pin will be on. 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.

To set the AL_PA:

1. Determine an unused AL_PA for the drive and refer to Table 3 on page 17 for its corresponding LID.

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

3. Jumper pins 1, 2, 3, 4, 7, and 8 as shown in Table 3 on page 17. By using hard addressing, you can specify one of 62 valid AL_PAs for the drive.

If you jumper all of the pins, the drive gets the AL_PA from a field in its vital product data (VPD). (An enclosure can set the AL_PA in the VPD through the RS-422 interface.) If you do not jumper any pins, the drive uses soft addressing to determine the AL_PA.

Step 7. Mount the Tape Drive into an Enclosure

Notes:

1. In the following procedure, you may find it easier to connect the cables to the

back of the tape drive (as described on pages 21 through 22) before you secure it to the enclosure.

2. The Ultrium Tape Drive may be shipped with or without a front bezel (see Figure 1 on page 1).

To mount the Ultrium Tape Drive into an enclosure:

1. Place the drive into the enclosure so that its tape load compartment faces the tape load compartment of the enclosure.

2. Insert two 6-32 screws into the mounting holes on the side brackets of the chassis (see 2 in Figure 7).

| | |

Attention: When inserted into the Ultrium Tape Drive, the length of the mounting screws must not exceed 2.0 mm (0.08 in.) from the outside of the chassis. If the length exceeds this measurement, the tape drive may become damaged.

< 2 mm (0.08 in.)

Figure 7. Mounting Holes on Ultrium Tape Drive. The holes are located on both sides of the drive. The tape drive is shown with a front bezel.

20 IBM Ultrium Internal Tape Drive

Step 8. Connect Power to the Tape Drive

The Ultrium Tape Drive is designed to be hot-pluggable (that is, you can physically install the drive into an enclosure without powering the enclosure off). If you install the drive in a hot-pluggable environment, watch for the indicators to behave as described in step 2.

To connect power to the Ultrium Tape Drive:

1. Connect the enclosure’s internal power cable to the power connector on the drive (if you are using a SCSI drive, see 3 in Figure 2 on page 10; if you are using Fibre Channel drive, see 1 in Figure 3 on page 11). Ensure that the connector is properly keyed.

2. Review the location of the single-character display and the status light on page 23 (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). Watch for the following while turning on the power to the enclosure:

Attention: If the single-character display does not come on, the drive may not be getting power.

v The single-character display increments, then becomes blank (not lit). v The status light briefly becomes solid amber, then becomes solid green.

After the single-character display becomes blank, the tape drive is ready for the checkout procedure in the next step.

Step 9. Perform a Checkout of the Tape Drive

To perform a checkout of the Ultrium Tape Drive:

1. Place the drive in maintenance mode (see “Placing the Drive in Maintenance Mode” on page 27).

2. Run the tape drive diagnostics (Function Code 1 in Table 7 on page 29). If an error code appears on the single-character display, go to Table 12 on page 53.

3. Run the SCSI or Fibre Channel wrap test to ensure that the interface is functional (see Function Code 6 in Table 7 on page 29).

4. Attach an RS-422 wrap plug and run the RS-422 wrap test to ensure that the serial interface is functional (locate Function Code 7 in Table 7 on page 29).

Step 10. Connect the RS-422 Interface

Note: Use this step only if you are installing the Ultrium Tape Drive into an

enclosure.

The Ultrium Tape Drive contains an RS-422 interface by which it can communicate with an enclosure.

To connect the RS-422 interface, connect the RS-422 cable to the J2 connector on

| |

the drive (see 4 in Figure 2 on page 10 and Figure 3 on page 11). Connect the other end of the cable to the enclosure.

Chapter 3. Installing 21

Step 11. Connect the Tape Drive to the SCSI or Fibre Channel Interface

To connect the Ultrium Tape Drive to a SCSI or Fibre Channel interface, choose one of the following procedures.

Connecting the Drive to a SCSI Interface

To connect the Ultrium Tape Drive Model T200 to the SCSI bus:

1. Connect the enclosure’s internal SCSI bus cable to the SCSI connector on the tape drive (see 1 in Figure 2 on page 10).

2. Run the appropriate SCSI attachment verification procedure on 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 59.

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

Connecting the Drive to a Fibre Channel Interface

| | |

To connect the Ultrium Tape Drive Model T200F to the Fibre Channel interface:

1. Connect the enclosure’s internal fiber cable to the Fibre Channel connector on the tape drive (see 3 in Figure 3 on page 11).

Note: Model T200F can be ordered with several lengths of fiber cabling, up to

61 m (200 ft). For ordering information, see Table 13 on page 81.

2. Run the Fibre Channel wrap test at the end of a cable that does not exceed 250 m (820 ft) (see Function Code 6 in Table 7 on page 29). Do not bend the cable more than a radius of 50.8 mm (2 in.) or the optical fiber may break.

3. Connect the fiber cable to an appropriate attachment (server, switch, or hub). For information about attaching the fiber cable, refer to the documentation for your server, switch, or hub.

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

22 IBM Ultrium Internal Tape Drive

To configure the tape drive to the server, or to configure the Model T200F Fibre Channel drive to a switch or hub, refer to the server’s documentation.

Chapter 4. Operating the Tape Drive

Attention: Before operating the Ultrium Internal Tape Drive, let the drive (and any

tape cartridges to be inserted) acclimate to the operating environment for 24 hours

Status Light

The status light (1 in Figure 8 on page 23) is a light-emitting diode (LED) that provides information about the state of the Ultrium Tape Drive. The light can be green or amber, and (when lit) solid or flashing. Table 5 lists the conditions of the status light and provides an explanation of what each condition means.

The status light also flashes green if the tape drive contains a cartridge during the power-on cycle. In this case, the drive completes POST and slowly rewinds the tape (the process may take approximately 13 minutes). The light stops blinking when the drive completes the recovery and is ready for a read or write operation. To eject the cartridge, press the unload button.

v If the light flashes once per second, an error occurred and the

tape drive or media may require service. Note the code on the single-character display, then go to Table 12 on page 53 to determine the action that is required.

v If the light flashes twice per second, the tape drive is updating

firmware through the field microcode replacement (FMR) tape, or the SCSI, Fibre Channel, or RS-422 interface (see “Updating the Firmware” on page 38).

v If the light flashes four times per second, the tape drive detected

an error and is performing a firmware recovery. It resets automatically.

Chapter 4. Operating 25

Single-character Display

The Ultrium Tape Drive features an LED (3 in Figure 8 on page 23) that presents a single-character code for:

v Diagnostic or maintenance functions v Error conditions and informational messages

Table 7 on page 29 lists each single-character code that is used for diagnostic or maintenance functions. Table 12 on page 53 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 of the tape drive.

Inserting a Tape Cartridge

To insert a tape cartridge:

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

2. Ensure that the write-protect switch is properly set (see “Setting the Write-Protect Switch” on page 43).

3. Grasp the cartridge so that the write-protect switch faces you (see 1 in Figure 9).

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.

Removing a Tape Cartridge

To remove a tape cartridge:

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

2. Press the unload button. The drive rewinds the tape and partially ejects the cartridge. The status light flashes green while the tape rewinds, then goes out before the cartridge partially ejects.

3. After the cartridge partially ejects, grasp the cartridge and remove it.

If you are unable to remove the cartridge, see “Manually Removing a Tape Cartridge” on page 73. Whenever you unload a tape cartridge, the tape drive writes any pertinent information to the cartridge memory.

Cleaning the Drive Head

Attention: To clean the drive head, use the IBM LTO Ultrium Cleaning Cartridge

or an IBM-approved cleaning cartridge. Clean the drive head whenever C displays on the single-character display and the

status light is solid green. To clean the head, insert the cleaning cartridge into the tape load compartment (see Figure 9 on page 26). The drive performs the cleaning automatically. When the cleaning is finished, the drive ejects the cartridge. The IBM LTO Ultrium Cleaning Cartridge is valid for 50 uses.

Placing the Drive in Maintenance Mode

The Ultrium Tape Drive can run diagnostics, verify write and read operations, verify

| | |

| |

a suspect tape cartridge, update its own firmware, and perform other diagnostic and maintenance functions listed in Table 7 on page 29. The drive must be in maintenance mode to perform these functions.

Attention: Maintenance functions cannot be performed concurrently with read or write operations. While in maintenance mode, the tape drive does not accept SCSI or Fibre Channel commands from the server. The tape drive does accept RS-422 interface commands.

To place the drive in maintenance mode:

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

2. Within a 1-second interval, press the unload button three times. The status light becomes solid amber, which means that the drive is in maintenance mode.

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/storagesmart/lto. You can update your drive’s firmware by:

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

SCSI, Fibre Channel, 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, Fibre Channel, or RS-422 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 code from a server that uses an IBM tape device driver, refer to the IBM Ultrium Device Drivers Installation and User’s Guide.

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

To update code from the RS-422 interface, see your library’s documentation.

Chapter 5. Using the Media

The IBM Ultrium Internal Tape Drive Models T200 and T200F use the following cartridge types:

v IBM LTO Ultrium Data Cartridge v IBM LTO Ultrium Cleaning Cartridge

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

In addition to using LTO Ultrium Tape Cartridges with up to 100 GB capacity, the tape drive reads and writes to certified LTO Ultrium Tape Cartridges that have capacities of 50 GB, 30 GB, and 10 GB.

Figure 10 shows the IBM LTO Ultrium Data Cartridge and its components.

1 Cartridge door 4 Label area 2 Leader pin 5 Insertion guide 3 Write-protect switch

Figure 10. The IBM LTO Ultrium Data Cartridge

Data Cartridge

The IBM LTO Ultrium Data Cartridge contains 1/2-inch, metal-particle tape that has a native data capacity of 100 GB. When processing the tape, the Ultrium Internal Tape Drive uses a linear, serpentine recording format, and reads and writes data on 384 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 LTO Ultrium Data Cartridge includes a Linear Tape-Open Cartridge Memory (LTO-CM) chip, which 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 cartridge door (1 in Figure 10 on page 41) protects the tape from contamination when the cartridge is out of the drive. Behind the door, the tape is attached to a leader pin 2. 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 3 prevents data from being written to the tape cartridge. The label area 4 provides a location for you to place a 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 5 is a large, notched area that prevents you from inserting the cartridge incorrectly.

The IBM LTO Ultrium Data Cartridge has a nominal cartridge life of 5000 load and unload cycles.

Cleaning Cartridge

The drive itself determines when a head needs to be cleaned. It alerts you by displaying C on the single-character display. To clean the head, insert the IBM LTO Ultrium Cleaning Cartridge into the tape load compartment (see Figure 9 on page 26). 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 25. The IBM LTO Ultrium Cleaning Cartridge is valid for 50 uses. The cartridge’s LTO-CM chip tracks the number of times that the cartridge is used.

42 IBM Ultrium Internal Tape Drive

Setting the Write-Protect Switch

The position of the write-protect switch on the tape cartridge (see 1 in Figure 11) 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.

(solid red), data cannot be written to the tape.

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

Chapter 5. Using the Media 43

Reattaching a Leader Pin

If the leader pin detaches from the tape in your cartridge, you must use the IBM Leader Pin Reattachment Kit (part number 08L9129) to reattach it. (Do not reattach the pin if you must remove more than 7 meters (23 feet) of leader tape.)

The first meter of tape 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 12). A plastic brace that holds the

cartridge door open.

v Cartridge manual rewind tool (see 2 in Figure 12). 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 12). 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 12. Leader Pin Reattachment Kit

A67E0042

44 IBM Ultrium Internal Tape Drive

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 13) 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 13. 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.

Chapter 5. Using the Media 45

2. To find the end of the tape inside the cartridge, attach the cartridge manual rewind tool (1 in Figure 14) 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 14. 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 15), 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.

7. Position the tape in the alignment groove of the leader pin attach tool (see 1 in Figure 16).

8. Place a new C-clip into the retention groove 2 (Figure 16) 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 46) into the cavity 3 (Figure 16) 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 16). 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.

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.

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

Chapter 5. Using the Media 47

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.

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.

Handling the Cartridges

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 Ultrium Internal Tape Drive, use the following guidelines:

v Before you use a cartridge, let it acclimate for at least 24 hours to the normal

operating environment.

v Ensure that all surfaces of a cartridge are dry before inserting it. v Do not insert a damaged tape cartridge into your Ultrium Tape Drive. A damaged

cartridge can interfere with the reliability of the drive. Before inserting a tape cartridge, inspect the cartridge case, cartridge door, and write-protect switch for cracks or breaks. If you need to recover data from a damaged cartridge, contact your nearest Customer Assistance Center (see “Getting Help” on page 90).

v Do not open the cartridge case at any time. The upper and lower parts of the

case are welded; separating them destroys the usefulness of the cartridge.

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. Although cartridges are shipped and

should be stored with the reel in the vertical position, you can temporarily lay the cartridges flat when moving them.

v Do not expose the tape cartridge to moisture or direct sunlight. v Do not degauss a tape cartridge that you intend to reuse. Degaussing makes the

tape unusable.

v Do not perform bulk erasure of the tape. Bulk erasure makes the cartridge

unusable.

| | | | |

v Do not expose recorded or blank tape 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 49.

48 IBM Ultrium Internal Tape Drive

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 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.

Chapter 5. Using the Media 49

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

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 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.

operating systems, refer to

| | | |

Raw sense data (as returned from the Ultrium Tape Drive) is documented in the

IBM Ultrium Internal Tape Drive Models T200 and T200F and IBM 3580 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 alternative ways for gathering such information from the IBM AS/400, Eserver iSeries, RS/6000, and Eserver pSeries servers.

Obtaining a Drive Dump

| |

You can obtain a drive dump by selecting a function code on the Ultrium Internal 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 Ultrium Internal Tape Drive:

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

2. Within a 1-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 second 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 nearest Customer Assistance Center (see “Getting Help” on page 90).

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. Open the tool and select the options to force the dump, read it, and write it to a file for analysis.

| | | |

| |

| | | |

| |

There are many device driver utilities and system tools that read data from a tape cartridge. For AIX-attached drives, the dd command or tapeutil (the IBM device driver utility) can be used. For Windows NT and Windows 2000, ntutil (another IBM device driver) can be used, but NT Backup cannot be used.

Note: After starting ntutil and opening the tape drive, select option 47: restore

data.

For more information about capturing and reading drive dumps, visit the web at http://www.storage.ibm.com/techsup/tapetech/tapedumps.htm.

For information about using IBM and non-IBM device driver utilities with Windows NT, Windows 2000, AIX, Sun Solaris, and HP-UX, see the IBM Ultrium Device Drivers Installation and User’s Guide. To learn about other facilities that read data from a tape, refer to your operating system’s documentation.

To determine where to send a file that contains a drive dump to be analyzed, contact your nearest Customer Assistance Center (see “Getting Help” on page 90).

Chapter 6. Resolving Problems 63

Viewing the Drive Error Log

The Ultrium 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-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 second 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 12 on page 53 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.

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 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

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

1. Ensure that the power is on to the Ultrium 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 7 on page 29).

v If the test runs successfully, replace the SCSI terminator first, then the SCSI

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

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 7 on page 29; 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.)

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.

on page 71).

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 7 on page 29). – 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 the SCSI Tape

Drive” on page 71).

Chapter 6. Resolving Problems 65

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 7 on page 29). – 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 the SCSI Tape

Drive” on page 71).

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 Tape Drive.

4. Replace the tape drive (see “Removing the SCSI Tape Drive” on page 71). 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 the SCSI Tape Drive” on page 71).

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.

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 “Supported Topologies” on page 4).

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 3).

4. 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 65.

5. Ensure that the Fibre Channel cables are installed correctly. Refer to the appropriate steps in “Chapter 3. Installing the Tape Drive” on page 9.

6. Go to one of the following procedures:

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 “Step 6. Set the Arbitrated Loop Physical Address (Fibre Channel Drive Only)” on page 15). The tape drive must be able to detect light and communicate with the server.

4. Run the Fibre Channel wrap test at the drive’s Fibre Channel connector (see Function Code 6 in Table 7 on page 29).

v If the test fails, replace the tape drive. v If the test is successful, go to step 5.

5. Run the Fibre Channel wrap test at the end of the fiber cable (see Function Code 6 in Table 7 on page 29).

v If the test fails, replace the fiber cable. v If the test is successful, go to step 6.

6. Check the Fibre Channel cable connection at the server.

7. Using a device driver utility such as ntutil or tapeutil, verify that the drive is properly configured and available at the server.

8. If the problem persists, the fault may be with the server’s hardware or software. Refer to your server’s service manual.

9. When the problem is corrected (or determined to be a server problem), restore all of the fiber cables to their correct position.

Fixing a Consistent Error with Multiple Drives on a Fibre Channel Loop

Use the following procedure to determine if all of the drives on the Fibre Channel have the problem:

1. Use a device driver utility (such as ntutil or tapeutil) to verify that the drive is available and properly configured at the server.

2. Determine the type of Fibre Channel topology that you are using (see “Supported Topologies” on page 4).

3. Using this guide or the service guides of associated switch, hub, or fiber products, try to isolate which part of the Fibre Channel Storage Area Network (SAN) is experiencing problems.

4. Perform one of the following: v If the problem exists on a small number of drives, go to “Fixing a Consistent

Error with a Single Drive on a Fibre Channel Loop” on page 67.

v If the problem exists with a large number of drives, perform the following

steps: a. Disconnect all except one failing drive on the Fibre Channel. b. Run the Fibre Channel wrap test to determine if a failure occurs on that

drive (see Function Code 6 in Table 7 on page 29). If it does, perform the procedure in “Fixing a Consistent Error with a Single Drive on a Fibre Channel Loop” on page 67.

c. Continue to connect one drive at a time to the Fibre Channel loop.

5. When the problem is corrected, restore all of the Fibre Channel cables to their correct position.

Fixing Intermittent Fibre Channel Errors

1. Determine the type of Fibre Channel topology that you are using (see “Supported Topologies” on page 4).

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

3. Check that each Fibre Channel cable does not exceed 500 m (1640 ft).

4. Ensure that all Fibre Channel cables are installed correctly. Refer to the appropriate steps in “Chapter 3. Installing the Tape Drive” on page 9.

5. Using this guide or the service guides of associated switch, hub, or fiber products, determine that a problem exists between the drive, drive cable, and the device to which they attach. Try to isolate which part of the Storage Area Network (SAN) is experiencing problems.

6. Using this guide or the service guides of associated switch, hub, or fiber products, verify that the SAN configurations are correct (such as switch zoning for drive sharing).

7. Obtain all errors reported by the drive to the server (see “Using Sense Data” on page 59), then contact your nearest Customer Assistance Center for error analysis (see “Getting Help” on page 90).

68 IBM Ultrium Internal Tape Drive

Resolving Media-Related Problems

| |

To resolve problems that are related to media, the Ultrium 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 83).

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 7 on page 29).

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 27 and Function Code 1 in Table 7 on page 29).

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.

| | |

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

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

Attention: Before performing this procedure, note the following:

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

replace the stuck tape cartridge after removing it and copying its data to another cartridge. If you choose to return the drive and the stuck tape cartridge to your reseller for maintenance, the tape cartridge will be scrapped.

v The use of a power screwdriver to perform this procedure 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 73

| |

| | |

| |

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 23).

2. Locate the access hole at the bottom of the unit (see 1 in Figure 23).

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 (the screw is not visible).

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

Figure 23. 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 cartridge’s takeup reel while you rotate the allen wrench 1 clockwise (do not let the wrench move counterclockwise): 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 75.

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. 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.

Continue rotating the screwdriver until the cartridge ejects. Remove the cartridge.

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

broken or the leader block is not in the home position. Go to “Fixing an Internal Jam” on page 76.

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, the procedure was successful. Go to step 10.

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

the loader mechanism is jammed. Go to “Fixing an Internal Jam” on page 76.

10. Remove the tape cartridge. 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 “Reattaching a Leader Pin” on page 44.

4. Place the tape drive so that the front faces you, then tilt it on its left side (see Figure 25).

5. At the bottom of the drive, locate the access hole (1 in Figure 25).

Attention: In the next step, do not let the leader-pin block touch the head. Damage may result to the head.

6. 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 (the screw is not visible).

7. With clean needle-nose pliers, grasp the end of the leader pin and pull it out of

the cartridge so that you can grip it with your fingers (see 2 in Figure 25).

8. While keeping the tape taut with your fingers, rotate the allen wrench clockwise

1 to wind the excess tape into the cartridge. Guide the leader pin toward the cartridge and drop it inside the cartridge door. Ensure that no tape is left outside of the cartridge. Remove the allen wrench.

Note: Do not attempt to seat the leader pin into the cartridge’s clips; this will

interfere with the motion of the leader-pin block.

Appendix B. TapeAlert Flags

| | |

TapeAlert is a patented technology and standard of the American National Standards Institute (ANSI) that defines conditions and problems that are experienced by tape drives. The technology enables a server to read TapeAlert flags from a tape drive through the SCSI, Fibre Channel, or RS-422 interface. The

server reads the flags from Log Sense Page 0x2E. This appendix lists the TapeAlert flags that are supported by the Ultrium Internal Tape Drive.
