Introduction a80hh015 The IBM LTO Ultrium 4 Half-High 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. It is the fourth generation in the Ultrium series of products, and is available with a Serial Attached SCSI interface (SAS). Figure 1-1. View of the drive Drive features The drive offers the following features: v Dual port 3 Gbps Serial Attached Small Computer Systems Interface (SAS) v Half height form factor v Native storage capacity of 800 GB per cartridge (1600 GB at 2:1 compression) v Maximum native data transfer rate of up to 120 MB per second v Burst data transfer rate of 300 MB per second v 256 MB read-and-write cache v Support for encryption on Ultrium 4 tape cartridges v Single Character Display (SCD) operator panel v Ready and Fault status lights v Maintenance Mode functions © Copyright IBM Corp. 2007 1-1 Front panel of the drive 1 2 3 4 a80hh014 5 Figure 1-2.

SAS drive rear panel element descriptions 1 Feature block switch (on the underside of the drive) 3 2 SAS/Power connector 4 RS-422 connector for library interfaces (LDI or ADI) selectable via Feature Switch 5 Fan SAS interface The drive has a dual-port 3 Gbps SAS (Serial Attached SCSI) host interface. A drive with a SAS (Serial Attached SCSI) interface can be linked directly to controllers. SAS is a performance improvement over traditional SCSI because SAS enables multiple devices (up to 128) of different sizes and types to be connected simultaneously with thinner and longer cables; its full-duplex signal transmission supports 3.0 Gb/s. In addition, SAS drives can be hot-plugged. 1-2 LTO Ultrium 4 Half-High Tape Drive SAS drives will auto-negotiate speed. There are no configurable topologies thus no setup is required for SAS interface. Physical Characteristics The drive contains a dual-port, SFF-8482 SAS connector. The SAS connector conforms to the Device Free (Plug) Connector form of the SFF-8482 standard “Unshielded Dual Port Serial Attachment Connector” as defined by the SFF standards body. For more information go to http://www.sffcommittee.org or see ftp://ftp.seagate.com/sff/SFF-8482.pdf for connector details. Cartridge compatibility The drive uses the IBM TotalStorage® LTO Ultrium 800 GB Data Cartridge and is compatible with the cartridges of its predecessor, the IBM LTO Ultrium 3 Half-High Tape Drive. The drive performs the following functions: v Reads and writes Generation 4 cartridges to Generation 4 format v Reads and writes Generation 3 cartridges to Generation 3 format v Reads Generation 2 cartridges v Does not write Generation 4 cartridge to Generation 3 format v Does not write Generation 3 cartridges to Generation 2 format v Does not write Generation 2 cartridges v Does not read or write Generation 1 cartridges The drive reads tapes that have been written by other licensed Ultrium 4 drives. It also writes to tapes that can be read by other licensed Ultrium 4 drives. In addition to using the IBM TotalStorage LTO Ultrium Data Cartridge with up to 800 GB capacity, the drive also offers read/write capability for certified LTO Ultrium tape cartridges. Speed Matching To improve system performance, the 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 six speeds when reading or writing the Ultrium 3 or Ultrium 4 cartridge format. Native data rates are as follows: v Ultrium 4 (Read/Write): 30, 48, 66, 84, 103, or 120 MB per second (MB/s) v Ultrium 3 (Read/Write): 30, 40, 50, 60, 70, or 80 MB per second (MB/s) v Ultrium 2 (Read only): 15, 19, 22, 26, or 30 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 the appropriate data rate at which to operate. 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. Chapter 1. Product description 1-3 Channel Calibration 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. Data cartridge capacity scaling The SET CAPACITY SCSI command enables a customer to capacity scale a data cartridge to enable faster random access. As an example, a customer could capacity scale a data cartridge to 20% of its normal length which improves the average access time by almost a factor of 5; however, it also reduces the native capacity of the tape to 80 GB. Encryption IBM LTO Ultrium 4 Half-High Tape Drive supports host Application Managed Encryption (AME), using T10 encryption methods. Data encryption is supported with LTO Ultrium 4 Data Cartridges only. The encryption enabled drive contains the necessary hardware and firmware to encrypt and decrypt host tape application data. Encryption policy and encryption keys are provided by the host application and there is no encryption setup required (or available) for this drive. A drive digital certificate is installed at manufacturing time. Each drive receives a unique serial number and certificate. The T10 Application may validate each drive instance by checking the drive’s digital certificate. Application-managed encryption is supported on AIX®, Windows Server 2003, Linux®, and Solaris. Encryption requires the latest device drivers available on the ftp down load site: ftp://ftp.software.ibm.com/storage/devdrvr/. For more details, see the IBM Tape Device Drivers Encryption Support documentation, and the IBM LTO Ultrium Tape Drive SCSI Reference documentation. Inhibit firmware down-leveling The drive provides the capability to prevent loading and installing drive microcode via a Field Microcode Replace (FMR tape) if the firmware level contained in the FMR tape is older than the code level already installed. This option is controlled by the host application. No checking will be performed if the firmware level is loaded via the host interface or the library interface. Feature Switches This drive contains eight factory-set feature switches by which the drive is configured for unique function. The feature switches are preset at the factory but are described here in case the feature switch settings need to be inspected for your application. The feature switch is located on the rear panel of the tape drive. Refer to “Rear panel of the SAS drive” on page 1-2 for the location of the switch. The switch positions are labeled 1 through 8 (see Table 1-1 on page 1-5). The on and off positions are marked on the switch. The default settings for the feature switches 1-4 LTO Ultrium 4 Half-High Tape Drive are all switches placed in the “OFF” position. Table 1-1.

Installing the drive Before starting this installation, read these instructions and compare them to the drive installation instructions for your enclosure. Avoiding drive damage To avoid static electricity damage when handling the drive, use the following precautions: v Limit your movement. Movement can cause static electricity to build around you. v Always handle the drive carefully. Never touch exposed circuitry. v Prevent others from touching the drive. v Before unpacking and installing the drive into an enclosure, touch its static-protective packaging to an unpainted metal surface on the enclosure for at least two seconds. This reduces static electricity in the packaging and your body. v When possible, remove the drive from its static-protective packaging and install it directly into an enclosure without setting it down. When this is not possible, place the drive’s packaging on a smooth, level surface and place the drive on the packaging. v Do not place the drive on the cover of the enclosure or on any other metal surface. Installation overview 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. “Unpack and acclimate the drive” “Power off the enclosure” on page 2-2 “Set the Feature switches” on page 2-2 “Install the SAS drive connector” on page 2-3 “Mount the drive into an enclosure” on page 2-3 “Connect and test power to the drive” on page 2-4 “Connect the internal LDI cable (optional)” on page 2-5 “Run drive diagnostics” on page 2-5 “Install device drivers” on page 2-5 “Connect the enclosure’s external SAS interface to the server” on page 2-5 “Connect the external LDI interface to the server (optional)” on page 2-5 “Configure the drive to the server” on page 2-6 Unpack and acclimate the drive Unpack the drive and store the packaging for future moves or shipping. 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 (1) as shown in Figure 2-1 on page 2-2). The recommended acclimation time is four hours after the drive has been unpacked or one hour after any condensation that you can see has evaporated, whichever is greater. When acclimating the drive, apply the following measures: © Copyright IBM Corp. 2007 2-1 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°C or 50°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°C or 104°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. a80hh010 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 four hours. 1 Figure 2-1. Temperature of the Half-high drive is taken near the air intake area Power off 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. Set the Feature switches The drive contains eight factory set feature switches (see 1 in Figure 1-3 on page 1-2) by which the drive can be configured for unique function. The switch positions are labeled 1 through 8. The on and off positions are marked on the switch. See Feature Switch Definitions in the following table. Table 2-1.

Feature Switch Definitions (continued) Switch ″On″ Function ″Off″ Function 7 Disable head brush ERP* Allows head brush ERP* 8 Reserved Reserved Note: The default settings for the feature switches are all switches placed in the “OFF” position. *The head brush error recovery procedure (ERP) is a last ditch effort the drive makes in some cases to recover from what would otherwise become a permanent read or write error by removing any debris which may have accumulated on the read/write head by use of the brush. To brush the head requires that the tape be unthreaded to expose the head. This forces the loader to be cycled to enable re-thread. During the loader cycling, the back of the cartridge will temporarily extend beyond the front of the bezel and this is not acceptable in some automation environments, which is why it can be disabled. Disabling the head brush ERP prevents this last ditch effort by the drive to prevent a permanent error and as a result, if the drive ever would invoke the head brush ERP (because of some error condition), it will instead immediately report that permanent error. Install the SAS drive connector Install the customer-supplied SAS drive connector to the rear panel of the drive (2 in Figure 1-3 on page 1-2). The SAS connector also includes the power connector for the drive. Mount the drive into an enclosure When mounting the drive into an enclosure: v Use an appropriate screw length. v Ensure that no objects such as screw heads, cables, or adjacent devices, are pressing against the frame. v Do not obstruct the ventilation slots at the rear of the drive. v Allow sufficient space for accessing the drive’s front panel controls. To mount the drive into an enclosure: 1. Remove the cover of your enclosure (refer to the instructions in the documentation provided with your enclosure). 2. Place the drive into the enclosure so that the tape load compartment of the drive faces the tape load compartment of the enclosure. 3. Insert two screws into the top mounting holes and two screws into the lower mounting holes (2 in Figure 2-2 on page 2-4) of the side brackets located on the left and right sides of the chassis. Attention When inserted into the drive, the length of the mounting screws must not exceed 2.5 mm (0.10 in.) for the upper mounting holes and 5.0 mm (0.20 in.) for the lower mounting holes inside the chassis. If the length exceeds this measurement, the drive may become damaged. Chapter 2. Installing 2-3 a80hh023 Figure 2-2. Mounting holes on the drive. The holes are located on both sides of the drive. The drive is shown with a front bezel. Connect and test power to the drive The drive does not contain its own power source; it must be powered externally. To connect and test power to the 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 (see 2 in Figure 1-3 on page 1-2).

For more information on ITDT, see “ITDT Firmware Update, Dump Retrieval and Library/Drive Test Tool” on page 3-23 5. Power-off the enclosure. 6. Disconnect the power cord from both the enclosure and the electrical outlet. Install device drivers For information about installing device drivers, refer to the documentation for your enclosure. Connect the enclosure’s external SAS interface to the server To connect the enclosure to the server: 1. Connect an external SAS 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 SAS attachment verification procedure from your server (for instructions, refer to the IBM Ultrium Device Drivers Installation and User’s Guide). If an error occurs, refer to “Using sense data” on page 5-8. If you want to power a device on or off while it is connected to the same bus as a drive, you can do so if, during the power-on cycle, you quiesce all devices (including the drive) on the bus. Connect the external LDI interface to the server (optional) Use this step only if your enclosure requires an LDI interface. Chapter 2. Installing 2-5 To check the 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). Configure the drive to the server To configure the drive to the server, refer to the documentation for that server. The drive is now ready for use. 2-6 LTO Ultrium 4 Half-High Tape Drive Chapter 3. Operating the Drive Operating the drive involves using the following front panel items: v Single-character Display (SCD) v SCD Dot v Status Lights v Unload Button Single-character Display (SCD) The SCD (4 in “Front panel of the drive” on page 1-2) presents a single-character code for: v Error conditions and informational messages v Diagnostic or maintenance functions (while in maintenance mode only) “Error Codes and Messages” on page 5-3 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. “Diagnostic and Maintenance Functions” on page 3-7 lists the single-character codes that represent diagnostic or maintenance functions. To initiate a function the unit must be in maintenance mode. The SCD is blank during normal operation. SCD Dot If a drive dump is present while the drive is in maintenance mode, a single red dot illuminates in the lower right corner of the SCD ( 8 ). To copy the dump, see “Function Code 5: Copy Drive Dump” on page 3-12. The SCD Dot (5 in “Front panel of the drive” on page 1-2) is on solid if the dump is in RAM memory. The SCD Dot flashes if the dump is in FLASH memory. The SCD Dot turns off when you obtain a dump (by using ITDT, a library command, or a SCSI command) or update the drive firmware. Note: If the drive dump is stored in RAM memory (SCD Dot on solid), the dump will be lost when you turn OFF the power or reset the drive. Status Lights The Status Lights (2 and 3 in “Front panel of the drive” on page 1-2) are light-emitting diodes (LEDs) that provides information about the state of the drive. The Ready status light is green and the Fault status light is amber, and (when lit) solid or flashing. Table 3-1.

Unload Button The Unload Button (1 in “Front panel of the drive” on page 1-2) performs the following functions: Table 3-3. Functions that the Unload Button performs Unload Button Function How to Initiate the Function Rewind the tape into the cartridge and eject the cartridge from the drive Press the Unload Button once. The Ready/Activity status light flashes green while the drive is rewinding and unloading. Note: During a rewind and eject operation, the drive does not accept SCSI commands from the server. Place the drive in maintenance mode Ensure that the drive is unloaded. Then, within two seconds, press the Unload Button three times. The drive is in maintenance mode when the Fault status light becomes solid amber and 0 appears in the SCD. Note: While in maintenance mode, the drive does not accept SCSI interface commands. Note: If you attempt to enter Maintenance Mode with a cartridge in the drive, the drive will rewind and eject the cartridge. Remove the cartridge and repeat the steps for entering Maintenance Mode. Scroll through the maintenance functions Exit maintenance mode Force a drive dump (part of the maintenance mode) While in maintenance mode, press the Unload Button once per second to increment the display characters by one. When you reach the character of the diagnostic or maintenance function that you want (see “Diagnostic and Maintenance Functions” on page 3-7), press and hold the Unload Button for three seconds. Press the Unload Button once per second until 0 displays. Then press and hold the Unload Button for three seconds. Maintenance mode is exited when the Ready/Activity status light becomes solid green and the SCD becomes blank. Attention: If the drive detects a permanent error and displays an error code, it automatically forces a drive dump (also known as a save of the firmware trace). 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 drive or you may lose the dump data. Choose one of the following procedures: v If the drive is in maintenance mode (Fault status light is solid amber), refer to “Function Code 4: Force a Drive Dump” on page 3-11. v If the drive is in operating mode (Ready/Activity status light is solid or flashing green), press and hold the Unload Button for ten seconds. If captured dump data exists, the drive places it into a dump area (for information about retrieving the data, see ). 3-4 LTO Ultrium 4 Half-High Tape Drive Table 3-3. Functions that the Unload Button performs (continued) Unload Button Function How to Initiate the Function Reset the drive Press and hold the Unload Button until the drive begins the reset procedure (Fault status light will be amber). Note: If a tape cartridge is loaded in the drive the drive will unload the tape. Repeat the ″Reset the drive″ procedure after the tape is unloaded. The drive saves a dump of the current drive state, then reboots to allow communication. Do not cycle power as this will erase the contents of the dump. Inserting a Tape Cartridge To insert a tape cartridge: 1. Ensure that the drive is powered on. 2. Ensure that the write-protect switch on the tape cartridge is properly set (see “Write-Protect Switch” on page 4-2). 3. Grasp the cartridge so that the write-protect switch faces you (see 1 in Figure 3-1). 4. Slide the cartridge into the tape load compartment. Note: a. If the cartridge is already in an ejected position and you want to reinsert it, remove the cartridge then insert it again. a80hh021 b. If the cartridge is already loaded and you cycle the power (turn it off, then on), the tape will reload. Figure 3-1. Inserting a cartridge into the drive Chapter 3. Operating 3-5 Removing a Tape Cartridge To remove a tape cartridge: 1. Ensure that the drive is powered-on. 2. Press the Unload Button. The drive rewinds the tape and partially ejects the cartridge. The Ready 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. Important: Always remove an ejected cartridge before reinserting. Whenever you unload a tape cartridge, the drive writes any pertinent information to the cartridge memory. Mid-tape Recovery If reset occurs while a cartridge is loaded, the drive will slowly rewind the tape and eject the cartridge. If a power cycle occurs while a cartridge is loaded, the drive will slowly rewind the tape. The drive will not automatically eject the cartridge. The Ready/Activity status light flashes during tape movement. Push the Unload Button to eject the cartridge. Cleaning the Drive Head Attention: When cleaning the drive head, use the IBM LTO Ultrium Cleaning Cartridge (see “Media Supplies” on page 6-1). You may use another LTO cleaning cartridge, but it may not meet the standards of reliability established by IBM. Clean the drive head whenever C displays on the Single-character Display and the Fault status light is flashing amber once per second. It is not recommended that you clean the drive head on a periodic basis; only when the drive requests to be cleaned. Note: In Maintenance Mode, a flashing C with the solid amber Fault status light, means to insert a cartridge, not clean the drive head. To clean the head, insert the cleaning cartridge into the tape load compartment (see “Front panel of the drive” on page 1-2). The drive performs the cleaning automatically in less than two minutes then ejects the cartridge. The drive will perform a short Load/Unload Test while ejecting the drive. Wait for the drive to finish before removing the cartridge. Note: The drive will automatically eject an expired cleaning cartridge. The IBM LTO Ultrium Cleaning Cartridge is valid for 50 uses. 3-6 LTO Ultrium 4 Half-High Tape Drive Diagnostic and Maintenance Functions The drive can: v Run diagnostics v Test write and read functions v Test a suspect tape cartridge v Update firmware v Perform other diagnostic and maintenance functions 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 commands from the server. Table 3-4 describes each diagnostic and maintenance function that the drive can perform, gives the function code which appears on the Single-character Display (SCD), and directs you to the instructions for performing the function. It is recommended that you use a customer-supplied scratch (blank) data cartridge for diagnostic testing. Note: During normal operation the fan only runs when cooling is required. The fan will be turned on/off during the POST and Run Drive Diagnostics to demonstrate the fan is operational. Table 3-4.

Updating Firmware Attention: When updating firmware, do not power-off the drive until the update is complete, or the firmware may be lost. It is the customer’s responsibility to ensure that this drive has the latest firmware. Periodically check for updated levels of drive firmware by visiting the web at http://www.ibm.com/storage/lto. Update drive firmware using: v The host interface v The LDI or RS-422 interface v The ITDT tool v A field microcode replacement (FMR) tape cartridge For instructions on obtaining a new firmware image or FMR tape, visit http://www.ibm.com/storage/lto. To update the firmware, refer to the following sections. Updating Firmware through the Host Interface When updating drive firmware by using the host 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 Tape 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 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 command may be received by the host interface or the LDI (RS-422) interface. For specific instructions about updating the drive firmware in a library, refer to the library documentation and procedures. 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 a Power-on Reset command is received and the drive does not contain a cartridge. 3-22 LTO Ultrium 4 Half-High Tape Drive ITDT Firmware Update, Dump Retrieval and Library/Drive Test Tool ITDT is a tool with multiple functional capability and is a very quick, convenient, and efficient method for drive firmware updates. As a note, drive dump retrievals can be performed by the tool as well. Below are some of the capabilities of this tool: v Firmware update capability to all IBM LTO Tape Drives. v The tool does not require any special device drivers. v The tool is available for most major platforms (Windows®, AIX®, SUN, Linux™, NetWare, AS/400). v The tool is capable of uploading drive dump files. v The tool’s primary function is thoroughly testing a drive. However, if the library is online to the server/host where the tool resides, ITDT will communicate with the drive through the library to load and unload a test cartridge thereby exercising some library functions. v The tool scans the host bus and will find and display for selection all IBM LTO devices. The tool will not display and allow for selection any non-IBM device. v Each function has ″Help″ selection which explains the required syntax as well as a brief explanation of the particular function. v A Readme text file will be posted with the .exe for a thorough explanation of initial tool download information from the web as well as explanation of tool capabilities. Refer to the ITDT Readme text file for information on tool usage. You can also refer to the web at http://www.ibm.com/storage/lto and look for information about the ITDT site. v The tool is currently a ″command line″ tool with a simple entry by keying in the executable name, itdt, from the directory where the tool is located. Updating the Firmware with an FMR Tape Cartridge Attention: A SAS drive requires a SAS firmware image. Other types of firmware images will not load on the SAS drive. To update the drive’s firmware from an FMR tape cartridge: 1. Create an FMR tape (see “Function Code 3: Create FMR Tape” on page 3-11). A single FMR tape can be used to update multiple drives if the drives are the same drive type (e.g. LTO Ultrium 4 Half-High) and host interface (e.g. SAS). 2. Update the drive firmware (see “Function Code 2: Update Drive Firmware from FMR Tape” on page 3-10). After updating the drive firmware, the FMR tape can be used as a data cartridge by using the ″Unmake FMR Tape″ function (see “Function Code 8: Unmake FMR Tape” on page 3-15). The SCD presents a series of random characters during the firmware download and update. The SCD briefly displays 8 , then becomes blank (not lit) when the firmware download and update is complete and there are no errors. An error code will be displayed if a firmware download or update error has been detected. The Ready/Activity status light is off and the Fault status light flashes amber during the firmware download and update. The Ready/Activity status light is solid green after the firmware download and update are complete. Chapter 3. Operating 3-23 3-24 LTO Ultrium 4 Half-High Tape Drive Chapter 4. Using Ultrium Media To ensure that your IBM Ultrium Tape Drive conforms to IBM’s specifications for reliability, use only IBM 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 LTO Ultrium Data Cartridge can not be used in other IBM non-LTO Ultrium tape products. Figure 4-1. The IBM LTO Ultrium Data Cartridge 1 LTO cartridge memory a chip that contains information about the cartridge and the tape, as well as statistical information about the cartridge’s use (For more information, see “Cartridge Memory Chip (LTO-CM)” on page 4-2.) 2 Cartridge door protects the tape from contamination when the cartridge is out of the drive 3 Leader Pin The tape is attached to a leader pin, behind the cartridge door. When the cartridge is inserted into the drive, a threading mechanism pulls the pin (and tape) out of the cartridge, across the drive head, and onto a non-removable take-up reel. The head can then read or write data from or to the tape. 4 Write-protect Switch prevents data from being written to the tape cartridge (For more information, see “Write-Protect Switch” on page 4-2.) 5 Label area provides a location to place a label. 6 Insertion guide a large, notched area that prevents the cartridge from being inserted incorrectly © Copyright IBM Corp. 2007 4-1 Types of Cartridges IBM Ultrium media is available in the following types: v “Data Cartridge” v “WORM (Write Once, Read Many) Cartridge” on page 4-3 v “Cleaning Cartridge” on page 4-4 Data Cartridge All generations of IBM Ultrium data cartridges contain 1/2-inch, dual-coat, metal-particle tape. When processing tape in the cartridges, Ultrium Tape Drives use a linear, serpentine recording format. Each generation of data cartridge is identified by case color, native data capacity, recording format and nominal cartridge life. Data Cartridge Native Data Capacity Case Color Ultrium 4 Green Ultrium 3 Recording Format* Nominal Cartridge Life (load/unload cycles) 800 GB (1600 GB at Reads and writes data on 896 2:1 compression) tracks, sixteen tracks at a time. 20,000 Slate Blue 400 GB (800 GB at 2:1 compression) Reads and writes data on 704 tracks, sixteen tracks at a time 20,000 Ultrium 2 Purple 200 GB (400 GB at 2:1 compression) Reads and writes data on 512 tracks, eight tracks at a time 10,000 Ultrium 1 Black 100 GB (200 GB at 2:1 compression) Reads and writes data on 384 tracks, eight tracks at a time 5,000 * The first set of tracks (sixteen for Ultrium 4 and 3; eight for Ultrium 2 and 1) 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 tracks for the return pass. This process continues until all tracks are written and the cartridge is full, or until all data is written. Cartridge Memory Chip (LTO-CM) All generations of the IBM LTO Ultrium Data Cartridges include a Linear Tape-Open Cartridge Memory (LTO-CM) chip (1 in Figure 4-1 on page 4-1), 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. The LTO-CM enhances the efficiency of the cartridge. For example, the LTO-CM stores the end-of-data location which, when the next time this cartridge is inserted and the WRITE command is issued, enables the drive to quickly locate the recording area and begin recording. The LTO-CM also aids in determining the reliability of the cartridge by storing data about its age, how many times it has been loaded, and how many errors it has accumulated. Whenever a tape cartridge is unloaded, the tape drive writes any pertinent information to the cartridge memory. The storage capacity of the LTO Generation 4 LTO-CM is 8160 bytes. LTO Generations 1, 2, and 3 have an LTO-CM capacity of 4096 bytes. Write-Protect Switch The position of the write-protect switch on the tape cartridge (see 4 in Figure 4-1 on page 4-1) determines whether you can write to the tape. If the switch is set to: v The locked position 4-2 LTO Ultrium 4 Half-High Tape Drive (solid red), data cannot be written to the tape. v The unlocked position (black void), data can be written to the tape. If possible, use your server’s application software to write-protect your cartridges (rather than manually setting the write-protect switch). This allows the server’s software to identify a cartridge that no longer contains current data and is eligible to become a scratch (blank) data cartridge. Do not write-protect scratch (blank) cartridges; the tape drive will not be able to write new data to them. If you must manually set the write-protect switch, slide it left or right to the desired position. Capacity Scaling To control the capacity of the cartridge (for example, to obtain a faster seek time) issue the SCSI command SET CAPACITY. For information about this command, refer to the IBM TotalStorage Ultrium Tape Drive SCSI Reference. WORM (Write Once, Read Many) Cartridge Certain records retention and data security applications require a Write Once, Read Many (WORM) method for storing data on tape. The LTO Ultrium generation 3 and 4 drives enable WORM support when a WORM tape cartridge is loaded into the drive. a67b0024 Because standard read/write media are incompatible with the WORM feature, a specially formatted WORM tape cartridge (see Figure 4-2) is required. Each WORM cartridge has a unique, worldwide cartridge identifier (WWCID), which comprises the unique CM chip serial number and the unique tape media serial number. See Ordering Media Supplies for information on how to choose and purchase the appropriate WORM tape cartridges for your library. Figure 4-2. Ultrium Data Cartridge on the left; WORM Cartridge on the right Type of Cartridge Case Color Native Data Capacity Recording Format* Ultrium 4 WORM Green and Silvery gray 800 GB (1600 GB at 2:1 compression) Reads and writes data on 896 tracks, sixteen tracks at a time. Ultrium 3 WORM Slate Blue and Silvery gray Reads and writes data on 704 tracks, sixteen tracks at a time 400 GB (800 GB at 2:1 compression) * The first set of tracks (sixteen for Ultrium 4 and 3; eight for Ultrium 2 and 1) 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 tracks for the return pass. This process continues until all tracks are written and the cartridge is full, or until all data is written. Chapter 4. Using Ultrium Media 4-3 Data Security on WORM Media Certain built-in security measures help ensure that the data written on a WORM cartridge does not become compromised, for example: v The format of a WORM Tape Cartridge is unlike that of standard read/write media. This unique format prevents a drive that lacks WORM-capable firmware from writing on a WORM tape cartridge. v When the drive senses a WORM cartridge, the firmware prohibits the changing or altering of user data already written on the tape. The firmware keeps track of the last appendable point on the tape. WORM Media Errors The following conditions cause WORM media errors to occur: v Information in the servo manufacturer’s word (SMW) on the tape must match information from the cartridge memory (CM) module in the cartridge. If it does not match: – a full-high tape drive will post a media Error Code 7 on the single-character display (SCD). – a library will post an error on the operator control panel v Inserting a WORM tape cartridge into a drive that is not WORM capable causes the cartridge to be treated as an unsupported medium. The drive will report a media Error Code 7. Upgrading the drive firmware to the correct code level will resolve the problem. Requirements for WORM Capability To add WORM capability to your LTO Ultrium generation 3 or generation 4 drive(s), drive firmware must be at the correct code level, and you must use either Ultrium 3 400 GB WORM tape cartridges or Ultrium 4 800 GB WORM tape cartridges (see “Media Supplies” on page 6-1). Cleaning Cartridge With each library, a specially labeled IBM LTO Ultrium Cleaning Cartridge is supplied to clean the drive head. The drive itself determines when a head needs to be cleaned. To clean the head, insert the cleaning cartridge into the tape load compartment of the drive or the Input/Output (I/O) Station of the library. The cleaning is performed automatically. When the cleaning is finished, the cartridge is ejected. Note: The drive will automatically eject an expired cleaning cartridge. IBM Cleaning Cartridges are valid for 50 uses. The cartridge’s LTO-CM chip tracks the number of times that the cartridge is used. Cartridge Compatibility Table 4-1.

Chapter 4. Using Ultrium Media 4-5 Tape cartridges can be ordered with the labels included or with custom labels. To order tape cartridges and bar code labels, see Ordering Media Supplies. The bar code for usage in IBM tape libraries must meet predefined specifications. They include (but are not limited to): v Eight uppercase alphanumeric characters, where the last two characters must be L4, L3, L2, L1, LT, or LU v Label and printing to be non-glossy v Nominal narrow line or space width of 0.423 mm (0.017 in.) v Wide to narrow ratio of 2.75:1 v Minimum bar length of 11.1 mm (0.44 in.) To determine the complete specifications of the bar code and the bar code label, visit the web at http://www.ibm.com/storage/lto (select LTO Support), or contact your IBM Sales Representative. When attaching a bar code label to a tape cartridge, place the label only in the recessed label area (see 4 in Figure 4-1 on page 4-1). A label that extends outside of the recessed area can cause loading problems in the drive. Attention: Do not place any type of mark on the white space at either end of the bar code. A mark in this area may prevent the library from reading the label. T O 1 2 3 L4 a69i0349 L Figure 4-3. Sample bar code label on the LTO Ultrium 4 Tape Cartridge. The volume serial number (LTO123), cartridge type (L4), and bar code are printed on the label. Guidelines for Using Bar Code Labels Apply the following guidelines whenever using bar code labels: v Use only IBM-approved bar code labels on cartridges to be used in an IBM tape library. v Do not reuse a label or reapply a used label over an existing label. v Before you apply a new label, remove the old label by slowly pulling it at a right angle to the cartridge case. v Use peel-clean labels that do not leave a residue after being removed. If there is glue residue on the cartridge, remove it by gently rubbing it with your finger. Do not use a sharp object, water, or a chemical to clean the label area. v Examine the label before applying it to the cartridge. Do not use the label if it has voids or smears in the printed characters or bar code (a library’s inventory operation will take much longer if the bar code label is not readable). v Remove the label from the label sheet carefully. Do not stretch the label or cause the edges to curl. 4-6 LTO Ultrium 4 Half-High Tape Drive v Position the label within the recessed label area (see 5 in Figure 4-1 on page 4-1). v With light finger pressure, smooth the label so that no wrinkles or bubbles exist on its surface. v Verify that the label is smooth and parallel, and has no roll-up or roll-over. The label must be flat to within 0.5 mm (0.02 in.) over the length of the label and have no folds, missing pieces, or smudges. v Do not place other machine-readable labels on other surfaces of the cartridge. They may interfere with the ability of the drive to load the cartridge. Handling Cartridges Attention: Do not insert a damaged tape cartridge into the drive. A damaged cartridge can interfere with the reliability of a 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. Incorrect handling or an incorrect environment can damage cartridges or their magnetic tape. To avoid damage to your tape cartridges and to ensure the continued high reliability of your IBM LTO Ultrium Tape Drives, use the following guidelines. 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. Provide Proper Acclimation and Environmental Conditions v Before using a cartridge, let it acclimate to the normal operating environment for 1 hour. If condensation is visible 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 Table 4-4 on page 4-10. 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. Chapter 4. Using Ultrium Media 4-7 v Inspect the cartridge for damage before using or storing it. v Inspect the rear of the cartridge (the part that loads first into the tape load compartment) and ensure that there are no gaps in the seam of the cartridge case (see 1 in Figure 4-4 and 4 in Figure B-2 on page B-2). If there are gaps in the seam (see Figure 4-4), the leader pin may be dislodged. Go to Appendix B, “Repairing a Cartridge,” on page B-1. Figure 4-4. Checking for gaps in the seams of a cartridge v Check that the leader pin is properly seated (see 2 in Figure B-2 on page B-2). v If you suspect that the cartridge has been mishandled but it appears usable, copy any data onto a good cartridge immediately for possible data recovery. Discard the mishandled cartridge. 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 B-1 on page B-2). If the leader pin has become dislodged, go to “Repositioning a Leader Pin” on page B-1. 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. Ensure Proper Packaging v When shipping a cartridge, use the 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 4-8 LTO Ultrium 4 Half-High Tape Drive been tested and found to be satisfactory . They are available at http://www.turtlecase.com. Figure 4-5. 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. Figure 4-6. Double-boxing tape cartridges for shipping Chapter 4. Using Ultrium Media 4-9 Environmental and Shipping Specifications for Tape Cartridges Before you use a tape cartridge, acclimate it to the operating environment to prevent condensation in the drive (the time will vary, depending on the environmental extremes to which the cartridge 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. Table 4-4.

The short term or operational storage environment is for storage durations of up to six months. 2. The long term or archival storage environment is for durations of six months up to ten years. 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 4000 oersted peak field over the entire space that the cartridge occupies). The tape should make two passes through the field at 90 degree orientation change for each pass to achieve complete erasure. Some commercial degaussers have two magnetic field regions offset 90 degrees from each other to accomplish complete erasure in one pass for higher throughput. Degaussing makes the cartridge unusable. If you burn the cartridge and tape, ensure that the incineration complies with all applicable regulations. 4-10 LTO Ultrium 4 Half-High Tape Drive Chapter 5.

The error code clears when you place the tape drive in maintenance mode. LTO Ultrium 4 Half-High Tape Drive Table 5-3. Error codes on the Single-character Display (continued) Error Code Cause and Action A Degraded operation. 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, determine whether the problem is with the drive or the media. Note: The drive is usable, though the Single-character Display continues to indicate an error and the Fault status light flashes amber. The error code may clear when you cycle power to the tape drive or place it in maintenance mode. To determine if the problem is with the drive hardware, or the tape media, perform the following procedures: 1. If possible, run the tape cartridge in a different drive. If the operation in the other drive fails and 6 or 7 displays, replace the media. If the operation succeeds, run the Test Cartridge & Media diagnostic (see “Function Code E: Test Cartridge & Media” on page 3-16). 2. If the Test Cartridge & Media diagnostic fails, replace the media. If it runs successfully, clean the failing drive and run the drive diagnostics (see “Cleaning the Drive Head” on page 3-6 and “Function Code 1: Run Drive Diagnostics” on page 3-9). Record the time it takes for the test to complete. Compare the recorded time with the ″Approximate Run Time″ above. If the test runs successfully but the execution time is significantly longer than the ″Approximate Run Time″, run “Function Code F: Write Performance Test” on page 3-17. If the Write Performance Test fails, replace the media. If the drive diagnostics run successfully, perform the operation that produced the initial drive error. 3. If the problem persists replace the drive. If it is not possible to run the tape cartridge in a different drive, perform the following procedures: 1. Clean the failing drive and run the drive diagnostics (see “Cleaning the Drive Head” on page 3-6 and “Function Code 1: Run Drive Diagnostics” on page 3-9). Record the time it takes for the test to complete. Compare the recorded time with the ″Approximate Run Time″ above. If the test runs successfully but the execution time is significantly longer than the ″Approximate Run Time″, run “Function Code F: Write Performance Test” on page 3-17. If the Write Performance Test fails, replace the media. If the drive diagnostics run successfully, run the Test Cartridge & media diagnostic (see “Function Code E: Test Cartridge & Media” on page 3-16). 2. If the Test Cartridge & Media diagnostic fails, replace the media. If it runs successfully, perform the operation that produced the initial drive error. 3. If the problem persists replace the drive. C The tape drive needs to be cleaned. Clean the tape drive. See “Cleaning the Drive Head” on page 3-6.

See Table 3-3 on page 3-4. v Refer to the error code displayed on the SCD if the drive reset and POST fails. v Retry the encryption operation if the drive reset and POST complete without errors. 3. Check the media. v Ensure the correct media is being used. Data encryption is supported with LTO Ultrium 4 Data Cartridges only. v Retry the encryption operation with the tape cartridge in another encryption enabled drive. Replace the media if the problem repeats with the same tape cartridge in multiple drives. If the problem occurred while the tape drive was running POST or diagnostics, replace the drive. The error code clears with the first attempted write/read after the encryption key is changed, or when the drive is placed in maintenance mode. E F P Fiber Port offline. NOT SUPPORTED ON THIS DRIVE. Fiber Channel Error. NOT SUPPORTED ON THIS DRIVE. Write operation to a write protected cartridge has been attempted (this includes any attempt to overwrite a WORM protected tape). Ensure the tape cartridge is the correct media type. Writes to Ultrium 2 tape cartridges are not supported in LTO 4 Half-High tape drives. If the tape cartridge is the correct media type, check the write-protect switch on the cartridge. The drive will not write to a write-protected cartridge. The error code clears when you remove the tape cartridge or place the tape drive in maintenance mode. Using sense data When a 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 2003, 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. 5-8 LTO Ultrium 4 Half-High Tape Drive Raw sense data (as returned from the 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®, System i, RS/6000®, and System p servers. Obtaining error information from the AS/400 or System i 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 System i 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.

Example of an error that suggests a SCSI bus problem Obtaining a drive dump You can obtain a drive dump by selecting a function code on the drive or by using a device driver utility (or a system tool) on the server. The sections that follow describe each method. Using ITDT For information on obtaining a drive dump using the ITDT tool, refer to “ITDT Firmware Update, Dump Retrieval and Library/Drive Test Tool” on page 3-23. Using the drive To obtain a drive dump directly from the drive, see “Function Code 5: Copy Drive Dump” on page 3-12 5-12 LTO Ultrium 4 Half-High Tape Drive Using a device driver utility 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). Viewing the Drive Error Log The 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 (SCD). To view the drive error log, refer to “Function Code 9: Display Error Code Log” on page 3-15 Resolving problems reported by the server The procedure for fixing interface bus errors varies, depending on whether the error is consistent or intermittent, and on your configuration. The sections that follow describe how to fix an error. Fixing SAS Bus Errors 1. Check that the tape drive power is on. 2. Verify the SAS cable is connected properly to the server and to the tape drive. 3. Replace SAS cable if it shows any signs of damage. Resolving media-related problems To resolve problems that are related to media, the drive’s firmware includes 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 VPD (Vital Product Data) area in NVRAM. Any failures that SARS detects are reported as TapeAlert flags on the server (see the IBM LTO Ultrium Tape Drive SCSI Reference for more information on TapeAlert flags). Attention If you insert the IBM LTO Ultrium Data Cartridge into another manufacturer’s drive, the SARS data in the cartridge memory may become lost or invalid. If you encounter a media-related problem with the drive, run the tape cartridge in a different drive, if possible. 1. If the operation in the other drive fails, replace the media. 2. If the operation succeeds, see “Function Code 1: Run Drive Diagnostics” on page 3-9. Chapter 5. Resolving problems 5-13 5-14 LTO Ultrium 4 Half-High Tape Drive Chapter 6.

Repairing a 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. 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 seven meters (23 feet) of leader tape.) The sections that follow describe each procedure. 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. Examples of Cartridge Problems Example: Split Cartridge Case (see ../commonfiles/ ltomedia_handling.dita#ltomedia_handling.dita/megap) 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. 2. Use the IBM Leader Pin Reattachment Kit (part number 08L9129) to correctly seat the pin. 3. Use data recovery procedures to minimize chances of data loss. 4. Review media-handling procedures. Example: Improper Placement of Leader Pin (see Figure B-1 on page B-2) 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. 3. Use data recovery procedures to minimize chances of data loss. Repositioning a Leader Pin 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) A leader pin that is improperly seated inside a cartridge can interfere with the operation of the drive. Figure B-1 on page B-2 shows a leader pin in the incorrect 1 and correct 2 positions. © Copyright IBM Corp. 2007 B-1 Figure B-1. Leader pin in the incorrect and correct positions. The cartridge door is open and the leader pin is visible inside the cartridge. To reposition the leader pin, refer to Figure B-2 and perform the steps below. 1. Slide open the cartridge door (1) and locate the leader pin (2) Note: If necessary, 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. 4. Close the cartridge door. 5. Ensure that there are no gaps in the seam of the cartridge Figure B-2. Placing the dislodged leader pin into the correct position B-2 LTO Ultrium 4 Half-High Tape Drive To rewind the tape, refer to Figure B-3 and perform the steps below. 1. Insert the cartridge manual rewind tool (1) into the cartridge’s hub (2) and turn it clockwise until the tape becomes taut. 2. Remove the rewind tool by pulling it away from the cartridge. 3. If you suspect that the cartridge has been mishandled but it appears usable, copy any data onto a good cartridge immediately for possible data recovery. Discard the mishandled cartridge. Figure B-3. Rewinding the tape into the cartridge 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: 1 2 A67E0042 3 Figure B-4. Leader Pin Reattachment Kit v Leader pin attach tool (1). A plastic brace that holds the cartridge door open. v Cartridge manual rewind tool (2). A device that fits into the cartridge’s hub and lets you wind the tape into and out of the cartridge. Appendix B. Repairing a Cartridge B-3 v Pin supplies (3). 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. To reattach a leader pin by using the IBM Leader Pin Reattachment Kit, refer to Figure B-5 and perform the steps below. 1. Attach the leader pin attach tool (1) to the cartridge (2) so that the tool’s hook (3) latches into the cartridge’s door (4). 2. Pull the tool back to hold the door open, then slide the tool onto the cartridge. Open the tool’s pivot arm (5). Figure B-5. Attaching the leader pin attach tool to the cartridge B-4 LTO Ultrium 4 Half-High Tape Drive To find the end of the tape inside the cartridge, refer to Figure B-6 and perform the steps below. 1. Attach the cartridge manual rewind tool (1) 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). 2. Continue to turn the rewind tool counterclockwise until approximately 13 cm (5 in.) of tape hangs from the cartridge door. If necessary, grasp the tape and pull gently to unwind it from the cartridge. 3. Remove the rewind tool by pulling it away from the cartridge. Set the tool and the cartridge aside. Figure B-6. Winding the tape out of the cartridge To remove the C-clip from the leader pin, refer to Figure B-7 and perform the steps below. 1. On the leader pin (1), 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. 2. 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. 3 2 A67E0036 1 Figure B-7. Removing the C-clip from the leader pin Appendix B. Repairing a Cartridge B-5 To attach the leader pin to the tape, refer to Figure B-8 and perform the steps below. 1. Position the tape in the alignment groove of the leader pin attach tool (1). 2. Place a new C-clip into the retention groove (2) on the leader pin attachment tool and make sure that the clip’s open side faces up. 3. Place the leader pin that was removed earlier into the cavity (3) 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. 4. Fold the tape over the leader pin and hold it with your fingers. 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. 5. 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. 6. Swing the pivot arm open and trim the excess tape (5) so that it is flush with the reattached leader pin (6). 7. Use your fingers to remove the leader pin from the cavity (3) in the leader pin attach tool. 8. 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. 9. Remove the rewind tool. 10. Remove the leader pin attach tool by lifting its end up and away from the cartridge. 2 1 4 3 6 A67E0037 5 Figure B-8.

Attention v The best solution for recovering data on a damaged cartridge is to send it to IBM for professional data recovery. v Before using this procedure, you must have exhausted all other means of removing the tape cartridge from the drive. Use this procedure only if you cannot remove the tape cartridge by using any other means. v Determine from the customer if the cartridge contains critical customer data. If the cartridge contains sensitive data that cannot leave the site, inform the customer that certain failure conditions diagnostics will be performed to test the drive for continued use. v The following removal procedures can destroy customer data! Use extreme care when handling or removing the customer’s tape cartridges to minimize tape damage and lost data. v DO NOT TOUCH the magnetic tape or tape path. Both are extremely sensitive to the oil and salt from your skin. Use clean, lint-free gloves when working around magnetic tape or the tape path components. v Electrostatic-sensitive components: Consider using an ESD Kit. v After you remove the tape cartridge, advise the customer to copy the data to another cartridge and to remove this tape cartridge from service. v Do not use power tools or magnetic tools to perform this procedure. v To avoid contamination and electrostatic-discharge damage to the drive, never touch the head or electronic components inside the drive. v If you cannot remove the cartridge from the drive using the following procedures, contact your next level of support. v The cartridge will not eject automatically at the end of a mid-tape recovery. Instead, the tape will be reloaded into the drive and may result in the loss of data. v INTERNAL COMPONENTS OF THE DRIVE ARE DELICATE AND CAN EASILY BE DAMAGED. EXERCISE EXTREME CAUTION WHEN MANUALLY REMOVING A CARTRIDGE THAT WILL NOT EJECT AFTER PRESSING THE UNLOAD BUTTON. Before You Begin 1. If you have not already done so, attempt to remove the cartridge with the device power ON and using library manager, a host application, or the unload button. When using the Unload button, press and hold the button for 12 seconds. This will cause the drive to eject the cartridge when it has completed the mid-tape recovery. 2. If you have not already done so, ensure the operator has issued the appropriate application commands to perform a rewind and unload of the cartridge. This is to ensure that the stuck cartridge is not due to a hang condition in the application. 3. If you have not already done so, attempt to remove the cartridge by power cycling the drive. Look for the drive to attempt a midtape recovery. C-2 LTO Ultrium 4 Half-High Tape Drive Note: It can take as long as five minutes for the cartridge to rewind and unload. 4. If the cartridge unloads, inform the operator that the cartridge is unloaded. If the cartridge does not unload, repeat steps 2 and 3 once before continuing with this procedure.
