IBM TS4300 tape library
The latest library from IBM, the IBM TS4300 tape library (Model 3555), is a highly expandable IBM Ultrium library that supports LTO-6 and LTO-7 drives. Starting with one 3U base module (Model L3A), you can add up to six expansion modules (Model E3A) in the same rack, giving a maximum capacity of 272 LTO cartridges, and up to 1.6 PB of data storage. The TS4300 base module can also be used as a table top library, as long as no further capacity expansion is required.
The base unit of the TS4300 tape library can accommodate either up to three Ultrium half-high tape drives, one Ultrium full-high, or a combination of one Ultrium full-high plus one Ultrium half high tape drive. SAS and Fibre Channel drives can both be installed. It can also hold up to 40 data cartridge slots in two removable magazines, including a standard five-cartridge I/O station. Other standard features include a 240 x 128 Monochrome control panel with a front USB port, a 10/100/1000 Ethernet Port, and a high-speed bar code reader.
On its maximum configuration of one base unit and six expansions, the TS4300 tape library can accommodate up to 21 Ultrium half-high tape drives, seven Ultrium full-high tape drives, or a combination of both based on the drive form factor. The space needed for one full-height drive equals two half-height drives.
This chapter includes the following topics:

11.2 Library expansion
As described earlier in this chapter, the base library can be easily scaled up with the addition of expansion modules. The TS4300 tape library uses a single robust flow-through design robotic system to access all drives and media. The design does not use complex pass-through ports or elevator systems, which removes the need for expensive duplication of robotics and control electronics with each library expansion. It also results in more reliable library operations.
Expansion modules can be installed above or below the base module, and the process takes approximately an hour or so to complete. When multiple expansion modules are used, they can be installed around the base module, if preferred. However, keep the base module at a user-friendly access height for access to the control panel. A full TS4300 library consists of three expansion modules on the top, then a base module, and three expansion modules on the bottom. I/O station slots can be configured in both base and expansion modules, depending on your preference.
|
Note: I/O station slots and drives are dedicated to logical libraries and are not shared. It is important to consider this factor when planning logical libraries for the TS4300.
|
For more information about the preferred library configuration setup, see IBM TS4300 Tape Library Machine Type 3555 Users Guide, SC27-4629.
|
Tip: Consider leaving a minimum clearance of 6 inches above the library for Service Clearance.
|
Figure 11-3 shows the TS4300 expansion path. The addition of each expansion module provides another 40 storage slots, unless it is the lowest module for the library installed in the rack, where only 32 slots are available.
Figure 11-3 TS4300 tape library expansion path
You can configure the I/O slots in each module to operate as I/O slots or storage slots. This method provides a high degree of flexibility. For example, in a library configuration of one L3A base unit and one E3A expansion unit, the following combinations are possible:
•No I/O slots (slots will become available for storage slots)
•A total of 4 I/O slots (all in the base module)
•A total of 9 I/O slots (that use the slots in the base module and the expansion module)
Expansion of the TS4300 tape library is granular and highly configurable. Table 11-1 shows the configuration options that are available as the base module expands. The cartridge accessor mechanism cannot access the bottom row of cartridge slots in the library.

Note: It is possible to disable all I/O stations in the TS4300, and use all the I/O slots as storage slots. In this case, a bulk cartridge load of the library is required, and any subsequent imports / exports of cartridges cause the library to be taken offline for the duration of the process.
|
11.3 Front panel components
Figure 11-4 shows the front view of a TS4300 tape library with a base module and expansion module on top. The access door (top cover) is on the top of the library to allow access to the interior of the library. The expansion module is shown with its I/O station open, ready for the import of cartridges. The front panel of the base module contains the Operator Control Panel and associated buttons to the right, power button, and magazine buttons.
Figure 11-4 Front view of a TS4300 6U library configuration
11.3.1 I/O station
I/O stations are located on the right side of the front panel of the library to enable the inserting and removing of cartridges without interrupting normal library operations. An expansion module’s I/O station has a capacity of up to 5 cartridges, depending on where it is located. If it is the lowest module in the rack for the library, it has only 4 I/O slots available.
Individual I/O station elements cannot be shared between logical libraries. Importing or exporting cartridges in a logical library without an assigned I/O station requires magazine access, which takes the whole library offline.
When an operator places cartridges in the I/O station and closes it, the library scans the slots to update the library inventory. Cartridges should then be moved to storage slot locations by using the Web User Interface (Web UI) or your backup application. Using the Web UI, cartridges can be moved from one logical library’s I/O station slot to a storage slot in another logical library, but a warning alert box will be shown and the action will need to be confirmed.
As explained in section 11.9, careful planning for logical libraries, including I/O station elements and cartridge drives, should be performed before configuration of the library occurs. Consideration should be given to media import and export operations during this planning phase.
11.3.2 Access door
Each TS4300 base module and expansion module has a top cover that allows access to the internal components of the library. This top cover is released by using two screwdrivers to depress small button clips near the front of the cover.
When the top cover is removed, all in-progress motion commands stop and the library is taken offline. When the top cover is replaced, the library returns any media in the accessor to its original storage slot.
|
Attention: Do not override the top cover switch because this action might result in accessor mechanism damage.
|
11.3.3 Operator control panel
The Operator Control Panel (OCP) consists of a black and white display and buttons on the front of the base module. Library operations, configuration, and service functions are performed from this display and its associated buttons.
The OCP has a power button, an LCD display, six navigation buttons, and five LEDs. With the OCP, you can monitor, configure, and operate most library functions from the library front panel. To use the OCP, use the six navigation buttons (up/down, left/right, Enter, Back).
The Web UI offers part of the same functionality as the operator window from a web browser, which enables remote access to the library. For more information about the operator panel and the web UI, see 11.7, “Library management” on page 311.
11.3.4 Power button
Pressing the power button on the front panel of a control module turns the library on or off. However, with the power button in the “off” position, power is still applied to the power supplies. The power button is used during library shutdown and to manually restart the library.
11.3.5 Front panel LEDs
Figure 11-5 shows the row of LEDs on the front of the library to the right of the power button:
•Green: Ready LED. Steady when power is on, flashing with tape Ready drive or library robotic activity.
•Blue: Unit ID LED. The unit identification (UID) LEDs are controlled by the user through the OCP Maintenance UID LED control panel. The UIDs on the OCP and base module back panel are activated and deactivated together. In addition, UIDs on drives and expansion module back panels can be activated separately. The UIDs are helpful for locating components of the library in a Data Center.
•Amber: Clean LED. On when a tape drive clean operation is recommended.
•Amber: Attention LED. Flashing if the library has detected a condition for which user attention is necessary, but the library can still complete most operations.
•Amber: Error LED. On, if an unrecoverable tape drive or library error occurs. A corresponding error message is displayed on the LCD panel. User intervention is required as the library is not capable of completing some operations.
Figure 11-5 Front panel LEDs
11.4 Rear panel components
Figure 11-6 shows the rear view of a 6U (one base module and one expansion module) TS4300 library and its major components. On the right side of the library, you can see the expansion cable which connects the base module library controller to the expansion module. Subsequent expansion modules are also “daisy-chained” together in this way.
Figure 11-6 Rear panel view of 6U library
11.4.1 Library Controller
The Library Controller manages the entire library, including the operator panel and accessor. It is responsible for running system tests to ensure that the library functions properly. The Library Controller stores vital product data (VPD), such as library settings and the library serial number.
The Library Controller indicates status with three vertically positioned LEDs. The color of the LED identifies the area of the component that is reported. They are, from top to bottom, as follows:
•Green: Ready LED. Library in Ready Status and operating properly.
•Amber: Error LED. Library in Error Status and the controller has a hardware issue.
•Blue: Unit ID LED. The unit identification (UID) LEDs are controlled by the user through the maintenance panel. The UIDs are helpful for locating components of the library in a Data Center.
11.4.2 Tape drives
The TS4300 library supports Half-High SAS and Fibre Channel, and Fibre Channel Full-High, Ultrium 7 and 6 drives. Ultrium 5 and earlier drives are not supported in the TS4300. Tape drives are hot-addable, which mean the library power remains on and operations of the existing tape drives are still active. Drives can be removed and installed without tools. The drive sleds are customer-replaceable units (CRU).
Drives are mounted in sleds that are installed into tape drive slots in the rear of the library. If a tape drive slot is empty, a metal plate covers the empty drive slots to prevent any debris from entering the library.
|
Important: If you install Full-High Fibre Channel drives in the TS4300, they must be in the lowest drive position. In this case, another Half-High drive can be installed above it, if wanted.
|
TS4300 tape library Ultrium 7 models
The following models are available for the TS3200 tape library:
•The 3555-L3A feature AGKL specifies an IBM Ultrium 7 Full-High Fibre Channel tape drive. The Ultrium 7 Fibre Channel drive has an 8 Gbps Fibre Channel interface that can be connected to Fibre Channel host adapters. The Ultrium 7 tape drive has a native data transfer rate of 300 MBps.
•The 3555-L3A feature AGKK specifies an IBM Ultrium 7 Half-High tape drive that has an SAS interface and a native data transfer rate of up to 6 Gbps.

•The 3555-L3A feature AGKG specifies an IBM Ultrium 7 Half-High tape drive that has an SAS interface and a native data transfer rate of up to 6 Gbps. The SAS Ultrium 6 tape drive comes with dual-port Mini-SAS (SFF-8088) interfaces. The Ultrium 6 tape drive provides a sustained native data transfer rate of 160 MBps.
•The 3573-L4U feature AGKF specifies an IBM Ultrium 6 Half-High Fibre Channel tape drive. The Ultrium 6 Fibre Channel drive has an 8 Gbps Fibre Channel interface that can be connected to Fibre Channel host adapters. The Ultrium 6 tape drive has a native data transfer rate of 160 MBps.
Figure 11-7 shows the back of an LTO-7 Full-High FC tape drive.
Figure 11-7 Back side of the LTO-7 Full-High FC tape drive
|
Tip: When connecting Fibre Channel tape drives are connected to a Fibre Channel host bus adapter (HBA) on the host server, ensure that the Fibre Channel Tape Support option is enabled on the Fibre Channel HBA so that proper class 3 error recovery is performed on the Fibre Channel. For more information about hot to set this option, see the HBA manufacturer.
|
11.4.3 Power supply
The library supports single and redundant power configurations. Each TS4300 base or expansion module has an upper and lower power supply. A single power configuration has a power supply that is installed in the upper slot of each library module. A redundant power configuration has power supplies that are installed in both upper and lower slots of each library module.
When two power supplies are used in a single module, the power load is spread evenly over both power supplies. If one of the power supplies fails, the power load is drawn entirely from the functioning power supply.
The single configuration has a single AC line input and a single DC power supply. The optional redundant configuration has dual AC line input and dual DC power supplies. A power supply can be hot-swapped if the library has a redundant power supply, and a redundant power supply can be hot added.
|
Note: There are no power switches on the power supplies on the back of the modules. The library should be powered down by using the power button on the base module and following the prompts. Except in emergency situations, use the shutdown procedure before removing power to the modules.
|
The power system of the library contains the following components:
•Power Supply Unit
•An AC power cord
The power supply has two LEDs that provide status information. The LEDs, which are to the right of the power cord, are green and white and indicate the following conditions:
•White Upper LED: AC power is connected
•Green Lower LED: Module powered ON
11.5 Interior components
Storage columns and the robotic system are in the body of the library.
11.5.1 Storage columns
Storage columns within the library store the tape cartridges while they are not loaded in a drive.
Figure 11-8 shows an example of the TS4300 tape library storage columns in the base model. The library contains four storage columns and the I/O Station, when configured, is in the upper right corner of the photo. Drives are visible in the center left side of the photo.
Figure 11-8 TS4300 tape library storage columns
11.5.2 Robotic system
The TS4300 robotic system includes the Y-axis assembly that houses the Y motor, which is attached to the carrier, and the bar code scanner. The climber moves the robotic system within the library. The accessor (robotic arm) has finger-like mechanisms that it uses to grab tape cartridges and move them to and from the I/O station, storage slots, and drives.
The bar code scanner reads each cartridge bar code label and the fiducial labels that identify the types of cartridge magazines and tape drives that are installed in the library.
Figure 11-9 shows the robot accessor in the center of the photo, and the robotic lock lever for transportation at the right side. Also visible above and below the accessor are the magazines that contain storage slots, and on the upper right side are the I/O slots if configured.
Figure 11-9 TS4300 robotic accessor
11.6 Optional features
The TS4300 tape library is highly configurable and enhanced functionality is available through the provision of optional features.
11.6.1 IBM Ultrium tape drives
The TS4300 tape library allows the following tape drive options:
•UItrium LTO-6 6 Gbps SAS Half-High drive
•UItrium LTO-7 6 Gbps SAS Half-High drive
•Ultrium LTO-6 8 Gbps Fibre Channel Half and Full High drives
•Ultrium LTO-7 8 Gbps Fibre Channel Half and Full High drives
UItrium LTO-5 technology and earlier drives are not supported in the TS4300 library.
For more information, see Chapter 2, “Overview of IBM LTO Ultrium tape drives” on page 45.
The IBM Ultrium tape drive contains the electronics and logic for reading and writing data, controlling the tape drive, managing the data buffer, and handling error recovery procedures. It is a CRU and can easily be replaced if necessary.

11.6.2 Redundant power supply
The service representative can hot swap the optional redundant configuration power supplies (FC1900) without interrupting library operation. Each supply in a control module and expansion module includes its own input AC power cord. During redundant operation, each supply carries half the power load. If a power cord or power supply fails, the second supply sources the complete power load. Optionally, you can install a single power supply and power cord if redundant power is not required.
The second power supply slot is physically covered in this configuration. The library can be upgraded to redundant power later. In case the configuration consists of the base model and expansion units, if a second power supply is added to one model, it also should be added to the other model.
11.6.3 Rack mounting kit
This feature (FC7002) provides the necessary rack mount hardware to mount the TS4300 Tape Library in a standard 19-inch equipment rack. Three EIA units are required. The feature (FC9848) Rack to PDU Line Cord must be ordered with the rack mount kit.
11.6.4 Feature code previews
The July 2017 IBM TS4300 Announcement states that IBM intends to introduce Path Failover and Library-Managed Encryption capabilities including support for IBM Security Key Lifecycle Manager in the fourth quarter of 2017.
For additional information, see the Product Preview section of the IBM announcement.
LTO Lib Managed Encryption (FC5900)
Library Managed Encryption requires the use of LTO Lib Managed Encryption feature code (FC5900).
Path failover (FC1682)
The path failover feature ensures the use of a redundant communication path when the primary path fails. Two types of path failover capabilities exist: Control Path Failover (CPF) and Data Path Failover (DPF).
Control Path Failover
A control path is a logical path into the library through which a server sends standard SCSI medium changer commands to control the logical library. Other control paths reduce the possibility that failure in one control path causes the entire library to be unavailable. Use of the Control Path Failover feature further reduces that possibility.
Data Path Failover
Data Path Failover provides a failover mechanism in the IBM device driver with which you can configure multiple redundant paths in a SAN environment. If a path or component failure occurs, the failover mechanism automatically provides error recovery to try the current operation again by using an alternative, preconfigured path without stopping the current job in progress. This feature provides flexibility in SAN configuration, availability, and management.
11.7 Library management
The library includes the following interfaces for management:
•Operator Control Panel (OCP) for local management
•Web UI for remote management through the network
The operator panel is on the front of the base library module. With the Operator Control Panel, operators can work locally on the library by using the touch panel. With the web UI, you can view and perform several library functions from remote sites.
11.7.1 Operator Control Panel
The Operator Control Panel is on the front panel of the base module with its associated buttons to the right side.
To access the menus, you must first log in by using the panel and buttons. The first display that is shown is the main panel, as shown in Figure 11-10 on page 312.
The main panel provides four menu options:
•Operation menu: Consists of commands that you can use to operate the library, such as Open Magazine, Open I/O/ Station, Inventory, and Move Cartridge from Drive to Home Slot.
•Configuration menu: Consists of commands that you can use to change the mode of operations of the library, insert and remove cartridges, load and unload drives, move media, and shut down and restart the library.
•Maintenance menu: Provides submenus for Library Tests, Viewing Problem Tickets, Drive and Library Firmware Upgrades, and System Reboots.
•Status Menu: Provides submenus for viewing status of Network Settings, Library, and Drives.

User privileges
User privilege levels are manually assigned to user accounts that are created within the library. Controlling access to windows and operations within the library preserves the integrity of the library and the data that is stored in the library.
The following types of user roles are available in the library:
•Administrative: Users are allowed access to the entire physical library and all of its logical libraries. Only one administrator user can be assigned the login name admin.
•Superuser: Users have more privileges and can perform more functions than Users, but less than Administrators.
•Monitor: Users are allowed to operate a logical library, but they cannot perform actions that affect the physical library.
Lightweight Directory Access Protocol support
Local authentication control is managed on the library. An administrator sets up accounts and privileges on the library. To use local authentication, a user must enter a local user name and password.
Remote authentication is managed by a Lightweight Directory Access Protocol (LDAP) server. Enabling LDAP allows existing user accounts that are on an LDAP server to be integrated into the library’s current user account management subsystem. User account information is centralized and shared by different applications, which simplifies user account management tasks.
Administrative users can configure and enable LDAP. After LDAP is enabled, users can access the library with LDAP or local authentication. To use LDAP authentication, a user must enter a directory service user name and password and specify an LDAP domain. To use local authentication, a user must enter only a local user name and password.
Administrative users can add, delete, and modify only local user account information. The library web client and operator panel do not allow you to create, modify, or delete user account information about an LDAP server. This procedure must be done by the directory service provider. For more information about LDAP user accounts, see your server documentation.

11.7.3 Encryption
The TS4300 tape library supports Application Managed Encryption (AME) for SAS and Fibre Channel drives. Data encryption is supported by the LTO Ultrium 7 and Ultrium 6 data cartridges.
AME is available at no charge for the TS4300 library. Many backup applications now support AME, including IBM Spectrum Protect.
|
Note: The July 2017 IBM TS4300 Announcement states that IBM intends to introduce Library-Managed Encryption capabilities including support for IBM Security Key Lifecycle Manager. For additional information see the Product Preview section of the IBM announcement.
Library-Managed Encryption will be supported with LTO Lib Managed Encryption feature code FC5900 in Fourth Quarter of 2017.
|
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 or host server. A drive digital certificate is installed at manufacturing time. Each drive receives a unique serial number and certificate. The application might validate each drive instance by checking the drive's digital certificate.
For more information about how to set up encryption on the TS4300 tape library, see IBM TS4300 Tape Library Machine Type 3555 User’s Guide, SC27-4629.
Encryption requires the latest device drivers, which are available at this website:
For more information, see 2.2, “Tape encryption overview” on page 68.
11.7.4 Notifications
The TS4300 has the following options that are available for sending notifications to the host:
•Simple Mail Transfer Protocol
Simple Mail Transfer Protocol (SMTP) automatically sends an email that contains event information to the email addresses that is specified whenever an event of a certain level occurs.
•Simple Network Management Protocol
Simple Network Management Protocol (SNMP) is a set of protocols for managing complex networks. SNMP works by sending messages that are called protocol data units (PDUs) to various parts of a network. Agents, which are SNMP-compliant devices that store data about themselves in Management Information Bases (MIBs) and return this data to the SNMP requesters, such as the host’s monitoring application.
11.8 Multipath architecture
With a multipath architecture, multiple systems can share the robotics of a library without middleware or a dedicated server (host) acting as a library manager. The library is controlled through the same physical connection as the connection that is used for the tape drives. By using multipath architecture, more control paths and data paths can be configured for any one logical library.
Multipath architecture has the following benefits:
•Eliminates the need for a separate dedicated control path to the library, which removes a single point of failure.
•Allows for Control Path Failover. If one control path is lost, for example, because of a tape drive hardware failure, the library can still operate through a different path without the need for manual intervention.
•Allows for Data Path Failover. For example, if access to a drive by using one HBA is lost, a separate path can be used without the need for manual intervention.
•Allows the library to be partitioned into multiple logical libraries. Each system that is connected to the library (through the tape drives) considers that it has access to an entire library (rather than merely part of a physical library) and is unaware that the robotics are shared.
Multipath architecture is compliant with SCSI and Fibre Channel interfaces.
The library is certified for SAN solutions, such as LAN-free backup.
11.8.1 Using multiple control paths
In addition to creating multiple logical libraries, any logical library can be configured to have more than one control path. When more control paths are configured, more library sharing configurations and availability options are made possible. Access to the logical library is on a first-come, first-served basis. Each control path for a logical library can accept commands while the library is in use by another control path.
To add or remove control paths, use the Web UI. For a particular logical library, you can enable as many control paths as there are drives in that logical library.
11.8.2 Using multiple control paths for Control Path Failover
Command failures and time outs are costly. You want your library to run smoothly and efficiently. To ensure continued processing, the library offers an optional Control Path Failover feature. By using this feature, the host device driver can resend the command to an alternative control path for the same logical library.
With Control Path Failover installed, the alternative control path can include another HBA, SAN, or library control path drive. The device driver initiates error recovery and continues the operation on the alternative control path without interrupting the application. AIX, Linux, Solaris, HP-UX, and Windows hosts are supported for this feature, which can be installed by the client.
For more information about how to use the Control Path Failover feature, see IBM Tape Device Driver Installation and Users Guide, GC27-2130.
11.8.3 Using multiple data paths for Data Path Failover
Data Path Failover and load balancing support native Fibre Channel Ultrium 7 and 6 tape drives in the library by using the IBM device driver for AIX, Linux, Solaris, HP-UX, and Windows. Data Path Failover provides a failover mechanism in the IBM device driver so that multiple redundant paths can be configured in a SAN environment.
If a path or component failure occurs, the failover mechanism can automatically provide error recovery to try the current operation again by using an alternative, preconfigured path without stopping the current job in progress. The failover mechanism provides flexibility in SAN configuration, availability, and management.
When a tape drive device is accessed that was configured with alternative paths across multiple host ports, the IBM device driver automatically selects a path through the HBA that has the fewest open tape devices. It then assigns that path to the application. This autonomic self-optimizing capability is called load balancing.
The dynamic load balancing support optimizes resources for devices that have physical connections to multiple HBAs in the same machine. The device driver dynamically tracks the use on each HBA as applications open and close devices. It also balances the number of applications that use each HBA in the machine. The dynamic load balancing support can help optimize resources and improve overall performance.
Furthermore, Data Path Failover provides autonomic self-healing capabilities similar to Control Path Failover, with transparent failover to an alternative data path if a failure occurs in the primary host-side path.
11.9 Working with logical libraries
Logical libraries are virtual sections within a library that present the appearance of multiple, separate libraries for the purposes of file management, access by multiple users, or dedication to one or more host applications. You must have at least one logical library in the TS4300, even if this logical library has all storage slot, I/O station slot, and drive resources assigned to it.
|
Note: I/O station slots and drives are dedicated to logical libraries and are not shared. It is important to consider this factor when planning logical libraries for the TS4300.
|
You create logical libraries by using one of the following methods:
•Basic Mode: The Basic Logical Library Wizard allows for simplified logical library creation by auto assigning all library elements into logical libraries based on the number of logical libraries that the user elects to create.
•Expert Mode: The Expert Logical Library Wizard allows an administrative user to assign the storage slots, drives, and I/O station slots per logical library on a granular level.
Every logical library must have at least one drive and one storage slot that is assigned to it. For example, if the library has two tape drives and 12 slots available, the maximum number of logical libraries that you can create is two.
If the library has only one logical library with all resources that are assigned to it, that logical library can be deleted to free resources for reallocating them to a new logical library, or it can be modified to free resources so that they can be reallocated to the new logical library.
Multiple logical libraries require the careful planning of library resources. If, for example, you are planning three logical libraries and have only two library modules, then careful consideration must be given to I/O station resources. Otherwise, you can choose to have a logical library with no I/O slots. In this case, import and export of cartridges causes the library to go offline while the cartridges are being loaded into the magazines.

Write Once Read Many media
Certain records retention and data security applications require a WORM method for storing data on tape. To meet this data storage requirement, a WORM feature is available on IBM LTO Ultrium generation 7, 6, 5, 4, and 3 drives. You can enable the WORM feature by upgrading to WORM-capable drive firmware and by using a special WORM tape cartridge.
A specially formatted WORM tape cartridge is required because standard read/write media are incompatible with the WORM feature. Each WORM cartridge has a unique, worldwide cartridge identifier (WWCID), which comprises the unique Cartridge Memory (CM) chip serial number and the unique tape media serial number.
For more information about WORM media, see “WORM tape format” on page 51.
11.10.2 Cleaning cartridges
A specially labeled IBM LTO Universal Ultrium Cleaning Cartridge cleans the drive in your library.
The drive determines when a head needs cleaning and communicates this information to the library. When the cleaning is finished, the drive ejects the cartridge, and the picker takes the cartridge and places it back in any storage slot. To remove a cleaning cartridge, export it from the library.
The IBM Cleaning Cartridge is valid for 50 uses. The Linear Tape-Open Cartridge Memory (LTO-CM) chip of the cartridge tracks the number of times that the cartridge is used.
11.10.3 Cartridge memory chip
All generations of the IBM LTO Ultrium data cartridges include an LTO-CM chip. This chip contains information about the cartridge and the tape (such as the name of the manufacturer that created the tape), and statistical information about the use of the cartridge.
The LTO-CM also helps to determine the reliability of the cartridge by storing data about its age, the number of times it was loaded, and the number of errors it accumulated. Whenever a tape cartridge is unloaded, the tape drive writes any pertinent information to the cartridge memory. The storage capacity of the Ultrium 6 Tape Cartridge Memory Chip is 16320 bytes.
