Glossary
access door
A door on the Base and Drive Module for service personnel to enter the library. See the section Open and Go Inside the Library.
Access Module
An optional module installed on the ends of a library that allows for bulk tape loading and redundant robotics support. One module supports bulk loading only. Two modules support bulk loading and redundant robotics. Abbreviated as "Accs" in the GUI and previously referred to in the SL3000 as an Access Expansion Module (AEM). See the section "Access Module (AEM)".
audit
The process of scanning the tape barcodes and updating the library database. The library automatically runs a full audit after initialization of one of the front access door has be opened. See the section "Audit All or Part of the Library".
Base card cage
The assembly in the Base module that houses controller cards which process commands from a host system, coordinate the activities of robots, CAPs, and tape drives, and monitors status inputs from sensors and switches. See the section "Base Module Card Cage".
Base Module
The main module in an SL4000 library that contains the card cage, power distribution units (PDUs), power supplies, and tape drives. This module is required for all libraries. Abbreviated as "Base" in the GUI. See the section "Base Module".
bulk load
Loading numerous tapes into the library using an Access Module. See also glossary term Access Module.
CAP pool
A group of CAPs that you can assign to a partition. The partition must have ownership of a CAP within the pool to use it for import/export. If a CAP pool is only assigned to one partition the partition automatically owns all CAPs in the pool. You can assign a CAP pool to multiple partitions, but each partition can only be assigned one CAP pool.
cartridge access port (CAP)
A device in the library that allows an operator to import or eject tapes. The SL4000 can contain rotational CAPs (26 slots) and AEM CAPs (234 slots). CAP is synonymous with import/export mail cell in SCSI and open system libraries. See the section "Cartridge Access Ports (CAPs)".
cartridge array
A plastic array of slots that holds multiple tapes. The number of slots per array depends on the location in the library. Arrays range from 8 to 14 slots.
Cartridge Module
Optional module in the library that adds storage capacity. Abbreviated as "Cart" in the GUI and previously referred to in the SL3000 as a Cartridge Expansion Module (CEM). See the section "Cartridge Module (CEM)".
cell
The location in the library in which a tape can be stored. See the section "View a List of All Cells in the Library".
cleaning tape
A tape that contains special material to clean the tape path in a tape drive. Has a "CLN" prefixed label. Contrast with glossary terms data tape and diagnostic tape. See the section "View a List of Cleaning Cartridges".
data tape
A tape that stores customer data. Contrast with glossary terms cleaning tape and diagnostic tape.
device
A mechanical component of the library, excluding tapes, but including all other physical components in the library (such as controllers, robots, CAPs and so on). Devices may be nested within each other. See the section "View Hardware Device Status".
diagnostic tape
A tape with a "DG" label that is used for diagnostic routines. Contrast with glossary terms cleaning tape and data tape. See the section "Run a Diagnostic Test".
drive array
A group of eight drive bays installed in the Base or Drive Module. Each bay can hold one drive tray. The Base Module holds up to three drive arrays. The Drive Module holds up to four drive arrays. See the section "Library Modules".
Drive Module
An optional library module that provides additional drive tray capacity and tape storage. Abbreviated as "Drive" in the GUI and previously referred to in the SL3000 as a Drive Expansion Module (DEM). See the section "Drive Module (DEM)".
dynamic World Wide Name (dWWN)
A feature that applies dynamic names to network devices rather than fixed names. When a dWWN-named device is replaced, it is assigned the same WWN as the one replaced, preventing reconfiguration of the network.
enter
The process of placing a tape into the cartridge access port (CAP) so that the library can insert it into a storage cell. Synonymous with import. See the section "Enter Tapes Through a CAP".
eject
The action in which the library places a tape into the cartridge access port (CAP) so that an operator can remove the tape from the library. Synonymous with export. See the section "Eject Tapes Through a CAP".
FC-SCSI
A library connection type which uses the small computer system interface over a physical Fibre Channel interface. See the section "SCSI Host Connection".
hardware activation file (feature activation file)
A .jar file that you purchase and upload to active optional feature on the library. See the section "Add or Remove Optional Library Features".
job
Some requests generate jobs which direct the library to perform some action necessary to complete the request. Some jobs can generate sub-jobs necessary to complete the parent job. See also glossary term request. See the section "View Library Requests, Jobs, and Resources".
label
An identifier associated with a tape. Labels are humanly readable, machine readable, or both. Synonymous with volume serial number (volser or vol-id). See the section "Volume Label Format".
library controller
Controls operations and communicates with the operator console and other modules. It resides in the Base card cage. See the section "Library Controller (LOC)".
magazine
A removable array that holds tapes for entering or ejecting tapes through the cartridge access port (CAP).
operator panel
A flat-panel display with a touch screen interface. This feature is attached to the front door of the Base Module. See the section "Operator Panel".
Parking Module
A converted Cartridge Module installed on the ends of a library configuration. Parking expansion modules can house a defective robot in a redundant robotics library. Robot maintenance is disruptive to the library. Abbreviated as "Park" in the GUI and previously referred to in the SL3000 as a Parking Expansion Module (PEM). Contrast with glossary term Access Module. See the section "Parking Module (PEM)".
partition
A portion of the library that presents itself to a host client as an independent library. Cells and drives in one partition cannot be seen by another partition. See the section "Partitioning".
physical capacity
The number of storage cells in the library (excludes system cells for cleaning tapes, diagnostic tapes, and the module identification block).
power distribution unit (PDU)
A device for the distribution of AC line power from one inlet to multiple outlets. Multiple PDUs provide higher availability because the power continues if one PDU (or its AC source if the PDUs use separate AC sources) loses power.
request
Every external command to the library (SCSI, SCI, GUI, SNMP, GET) and many internal actions will result in a request. A request may spawn a job to direct the library to perform the actions necessary to complete the request. See also job. See the section "View Library Requests, Jobs, and Resources".
robot
An electromechanical device that moves tapes among CAPs, storage cells, and drives. One or two robots are used in an SL4000 library. See the section "Robot".
safety door
The rolling "garage door" that separates the Access Module from the rest of the library. During service operations, the safety door lows to prevent the robot from striking someone working inside the Access Module. See the section "Access Module (AEM)".

A four-digit number that represents the addressing scheme used by hosts operating on a Fibre Channel interface. See also FC-SCSI. See the section "View the SCSI Element IDs".
service area
The space surrounding the library for service representatives to perform maintenance. See the section "Covers, Doors, and Service Clearances".
slot
A location in the library than can hold a device. Drive bays and slots in the Base card cage are examples of slots. A slot is different from a cell. Cells hold tape cartridges.
spoofed serial numbers
A feature that overrides the manufacturer's serial number of an LTO tape drive with the right most 10 characters of the drive tray serial number. See Drive Serial Number Spoofing.
StorageTek Library Control Interface (SCI)
The web services (WSDL) interface used to control the library.
system cell
Cell reserved by the library as a drop-off cell or used to store a cleaning or diagnostic tape.
tape cartridge
A container holding magnetic tape that can be processed without separating the tape from the container. The library uses data, diagnostic, and cleaning tapes. Sometimes a tape cartridge is referred to as "tape", "cartridge", or "media". See the section "Tape Cartridges (Media)".
tape drive
An electromechanical device that moves magnetic tape and includes mechanisms for writing and reading data to and from the tape. Sometimes referred to as "drive". See the section "Drives".
