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 it reads or writes 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 (MBps) v Ultrium 3 (read/write): 30, 40, 50, 60, 70, or 80 MBps

2 LTO Ultrium 4 Half High Tape Drive

a80hh024

(LDI or ADI) selectable through feature switch 5

v Ultrium 2 (read only): 15, 19, 22, 26, or 30 MBps

If the net (compressed) data rate of the server is between two of the active 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.

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 transfer function of the recording channel, the media, and the characteristics of the drive head.

Encryption

The 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 no encryption setup is 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 might validate each drive instance by checking the digital certificate of the drive.

SAS interface

Application-managed encryption is supported on Windows Server 2003, Linux and Solaris. Encryption requires the latest device drivers that are available for the tape drive. To download the latest device drivers, complete the following steps.

Note: Changes are made periodically to the IBM website. The actual procedure

might vary slightly from what is described in this document.

1. Go to http://www-947.ibm.com/support/entry/portal/.

2. In the Search within all of support & downloads text field at the bottom of

the screen, type tape files and press Enter.

3. In the list of search results, click the link Tape Files (index) - Software for tape drives and libraries.

A drive with a SAS (Serial Attached SCSI) interface can be linked directly to controllers. SAS provides better performance than 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 Gbps. In addition, SAS drives can be hot-plugged.

SAS drives auto-negotiate speed. There are no configurable topologies; therefore, feature switches are associated with SAS.

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

Chapter 1. Product description 3

standards body. For more information, see http://www.sffcommittee.org or ftp://ftp.seagate.com/sff/SFF-8482.pdf for connector details.

Chapter 2. Installing the drive

Depending on the type of enclosure, installation procedures might vary. Refer to the enclosure documentation for drive installation. The following generic procedure can be used if the enclosure documentation is not available.

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 in 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.

Unpack the drive

About this task

Unpack the drive and store the packaging for future moves or shipping.

Acclimate the drive and media

About this task

Acclimation time is required if the temperature of the drive and media when unpacked is different than the temperature of its operating environment (measured at the front of the bezel near the air intake area as shown in Figure 4). 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:

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

sufficient humidity, condensation might 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.

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.

Figure 4. Temperature of the drive is taken near the air intake area [1]

Power off the enclosure

Procedure

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 Ultrium 4 Tape Drive has eight factory-set feature switches by which the drive is configured for various functions. The feature switches are preset to the Off position at the factory but are described here in case you must change the feature-switch settings for your application.

6 LTO Ultrium 4 Half High Tape Drive

a80hh010

The feature switches are on the rear panel of the tape drive. See 1 in the Figure 3 on page 2 for the location of the switches. The switches are labeled 1 through 8 and the On and Off positions are marked. The feature switches are defined in the following table.

Table 2. Feature switch definitions

Switch On function Off function

1 Library interface at 9 600 baud /

polled 2 Library interface uses two stop bits Library interface uses one stop bit 3 Reserved Reserved 4 Library interface at 115 000 baud

rate 5 Enable ADI Enable LDI 6 Reserved Reserved 7 Disable head brush ERP* Enable 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 intended to prevent a permanent read or write error by removing debris that might have accumulated on the read or write head. In order to brush the head, the tape must 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. Extension of the cartridge is problematic in some automation environments, so you have the ability to disable this function. If the head brush ERP is disabled, the drive will immediately report the permanent error instead of activating the head brush ERP.

Library interface at 38 400 baud / non-polled

Switch 1 active

Mount the drive in an enclosure or server

About this task

When you mount the drive in an enclosure, observe the following guidelines:

v Use the installation instructions for your enclosure if possible. v Use the drive rails that come with your enclosure or server, unless you have

x3400 or x3500 System x servers. Mount the drive into x3400 or x3500 System x servers using the metal rails included with your tape drive.

v Do not obstruct the ventilation slots at the rear of the drive.

Attention: When the mounting screws or drive rail prongs are inserted into the drive, they must not extend farther than 2.5 mm (0.098 in.) inside the chassis. Otherwise, they might damage 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 internal power cable to the power connector on the drive (see 2 in “Rear view of the drive” on page 2).

4. Connect the power cord to the enclosure and to the electrical outlet.

5. Review the location of the single-character display (SCD) and the status LED in

Figure 2 on page 2. To ensure that the drive is receiving power, watch for the following while turning on the power to the enclosure:

v During the power-on/initialization and POST (Power-On Self Test), the SCD

briefly displays

, then becomes blank (not lit) when POST is complete and there are no POST errors. If a POST error has been detected, an error code will be displayed in the SCD and the status LED will flash amber.

8 LTO Ultrium 4 Half High Tape Drive

Attention: If the SCD does not come on, the drive might not be getting

power.

v The status LED will be OFF during the initial power-on and initialization.

The status LED briefly becomes green and then becomes amber during the remainder of the power-on and initialization phase. The status LED becomes solid green after the power-on/initialization and POST are complete.

6. Power-off the enclosure.

7. Disconnect the power cord from both the enclosure and the electrical outlet.

Connect the internal cable

About this task

Connect the enclosure internal SAS cable to the SAS connector on the drive. Attach the host side (data and power) of the SAS cable included with your tape drive to the SAS and power connectors on your server. Then, attach the drive side to the drive connector (see 2 in Figure 3 on page 2).

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 LED v Unload button

Single-character display (SCD)

The SCD (2 in Figure 2 on page 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 46 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 16 lists the single-character codes that represent diagnostic or maintenance functions. To initiate a function, the unit must be in Maintenance Mode.

SCD dot

Status LED

The SCD is blank during normal operation.

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 ( “Function Code 5: Copy drive dump” on page 24.

The SCD Dot is on solid if the dump is in ROM 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, a SCSI command, or "Function Code 5: Copy Drive Dump) or update the drive firmware.

Note: If the drive dump is stored in ROM memory (SCD Dot on solid), the dump

will be lost when you turn OFF the power or reset the drive.

The status light-emitting diode (LED) (4 in Figure 2 on page 2) that provides information about the state of the drive. The LED can be green or amber, and (when lit) solid or flashing. Table 3 on page 12 lists the conditions of the status light and single-character display (SCD) and provides an explanation of what each condition means. The SCD dot – a small LED dot near the lower right corner of the single-character display – serves as a dump indicator. When this dot is lit, a dump file is stored in the drive and can be retrieved.

Updating the firmware with an FMR tape cartridge

About this task

To update the drive firmware from an FMR tape cartridge, complete the following steps:

Chapter 3. Operating 35

1. Create an FMR tape (see “Function Code 3: Create FMR tape” on page 23). A single FMR tape can be used to update multiple drives if the drives are the same drive type (e.g. LTO Gen4) and host interface (e.g. SCSI, SAS, fibre channel).

2. Update the drive firmware (see “Function Code 2: Update drive firmware from FMR tape” on page 22).

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 27).

Types of cartridges

Ultrium media is available in the following types:

v “Data cartridge” v “WORM (Write Once, Read Many) cartridge” on page 39 v “Cleaning cartridge” on page 40

Data cartridge

All generations of Ultrium data cartridges contain a half-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.

* 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.

Cartridge Memory chip (LTO-CM)

All generations of the LTO Ultrium Data Cartridges include a Linear Tape-Open Cartridge Memory (LTO-CM) chip (1 in Figure 7 on page 37), 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 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 7 on page 37) determines whether you can write to the tape. If the switch is set to:

v The locked position v The unlocked position (black void), data can be written to the tape.

If possible, use your server application software to write-protect your cartridges (rather than manually setting the write-protect switch). This allows the server 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.

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

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.

Because standard read/write media are incompatible with the WORM feature, a specially formatted WORM tape cartridge (see Figure 8) 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.

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 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)

Chapter 4. Using Ultrium media 39

– 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.

Cleaning cartridge

With each library, a specially labeled 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.

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 might 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 LTO Ultrium Tape Drives, use the following guidelines.

Provide training

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

gather.

40 LTO Ultrium 4 Half High Tape Drive

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

one 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 7 on page 44.

Perform a thorough inspection

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

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

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

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

compartment) and ensure that there are no gaps in the seam of the cartridge case. If there are gaps in the seam (see Figure 9 on page 42), the leader pin might be dislodged.

Chapter 4. Using Ultrium media 41

Figure 9. Checking for gaps in the seams of a cartridge

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

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

the tape 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 been tested and found to be satisfactory . They are available at

http://www.turtlecase.com.

42 LTO Ultrium 4 Half High Tape Drive

Figure 10. 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 11. Double-boxing tape cartridges for shipping

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).

Chapter 4. Using Ultrium media 43

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

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

Disposing of tape cartridges

Under the current rules of the U.S. Environmental Protection Agency (EPA), regulation 40CFR261, the LTO Ultrium Tape Cartridge is classified as non-hazardous waste. As such, it can 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.

Particulate contamination

Attention: Airborne particulates (including metal flakes or particles) and reactive gases acting alone or in combination with other environmental factors such as humidity or temperature might pose a risk to the tape drive that is described in this document. Risks that are posed by the presence of excessive particulate levels or concentrations of harmful gases include damage that might cause the tape drive to malfunction or cease functioning altogether. This specification sets forth limits for particulates and gases that are intended to avoid such damage. The limits must not be viewed or used as definitive limits, because numerous other factors, such as temperature or moisture content of the air, can influence the impact of particulates or environmental corrosives and gaseous contaminant transfer. In the absence of specific limits that are set forth in this document, you must implement practices that maintain particulate and gas levels that are consistent with the protection of human health and safety. If IBM determines that the levels of particulates or gases in your environment have caused damage to the tape drive, IBM may condition provision of repair or replacement of tape drive or parts on implementation of appropriate remedial measures to mitigate such environmental contamination. Implementation of such remedial measures is a customer responsibility.

Appendix D. TapeAlert flags supported by the drive

TapeAlert is a standard that defines status conditions and problems experienced by devices such as tape drives, autoloaders, and libraries. The standard enables a server to read TapeAlert messages (called flags) from a tape drive via the SCSI bus. The server reads the flags from Log Sense Page 0x2E.

This library is compatible with TapeAlert technology, which provides error and diagnostic information about the drives and the library to the server. Because library and drive firmware might change periodically, the SNMP interface in the library does not require code changes if devices add additional TapeAlerts that are not supported today. However, should this occur, the MIB is written to minimize impact to the SNMP monitoring station. At the time of this writing, the TapeAlert flags in this appendix correctly represent TapeAlerts that will be sent. The MIB file should not be taken to mean that all traps that are defined in the MIB will be sent by the library or that they will be sent in the future.

This appendix lists TapeAlert flags that are supported by the Ultrium Tape Drives.

Table 13. TapeAlert flags supported by the Ultrium Tape Drive

Flag

Number Flag SNMP Trap Description Action Required

3 Hard error Yes Set for any unrecoverable read,

write, or positioning error. (This flag is set in conjunction with flags 4, 5, or 6.)

4 Media Yes Set for any unrecoverable read,

write, or positioning error that is due to a faulty tape cartridge.

5 Read failure Yes Set for any unrecoverable read

error where isolation is uncertain and failure could be due to a faulty tape cartridge or to faulty drive hardware.

6 Write failure Yes Set for any unrecoverable write

or positioning error where isolation is uncertain and failure could be due to a faulty tape cartridge or to faulty drive hardware.

8 Not data grade No Set when the cartridge is not

data-grade. Any data that you write to the tape is at risk.

9 Write protect No Set when the tape drive detects

that the tape cartridge is write-protected.

See the Action Required column for Flag Number 4, 5, or 6 in this table.

Replace the tape cartridge.

If Flag 4 is also set, the cartridge is defective. Replace the tape cartridge.

If Flag Number 9 is also set, make sure that the write-protect switch is set so that data can be written to the tape (see “Write-protect switch” on page

38). If Flag Number 4 is also set, the cartridge is defective. Replace the tape cartridge.

Replace the tape with a data-grade tape.

Ensure that the cartridge write-protect switch is set so that the tape drive can write data to the tape (see “Write-protect switch” on page

38).

55 Loading Failure Yes When loading a tape into a

drive, a hardware malfunction can prevent the tape from being loaded into the drive, or the tape may actually get stuck in the drive.

Possible causes:

1. A drive hardware error that prevents the tape from being loaded.

2. A damaged tape that cannot be loaded in the drive.

Take this action if the tape cartridge will not load in the drive:

1. Remove the tape cartridge from the library and inspect it for damage. If damaged, discard it.

2. Try another cartridge in that tape drive. If it still fails, replace the drive sled.

Take this action if the tape is stuck in the drive:

1. Attempt to unload the tape from the drive using the host backup application that is currently using the drive, or using the remote or local UI.

2. If the cartridge will not unload, contact Service for assistance.

56 Unload Failure Yes When attempting to unload a

tape cartridge, a drive hardware malfunction can prevent the tape from being ejected. The tape may actually be stuck in the drive.

Possible causes:

1. A drive hardware error that prevents the tape from being unloaded.

2. A damaged tape that cannot be unloaded from the drive.

Take this action if the tape will not unload from the drive:

1. If possible, manually remove the tape cartridge from the drive and inspect it for damage. If damaged, discard it.

2. Try removing the drive sled and replacing it. This will cause the drive sled to reboot. A reboot should cause the tape cartridge to rewind and unload if possible. If the cartridge unloads, remove it from the library and inspect it. If damaged, discard it.

Take this action if the tape is stuck in the drive:

1. Attempt to unload the tape from the drive using the host backup application that is currently using the drive, or via the remote or local UI.

2. If the cartridge will not unload, contact Service for assistance.
