The HBA sends and receives to and from the tape drive. Addressing StorageTek tape drives use: Port name, Node name, and Port ID for login validation. The StorageTek registration ID is 24 bits consisting of: •...
Page 39: Terms And Definitions
Terms and Definitions Terms and Definitions Tables throughout this chapter use the following terms for compliance with the American National Standards Institute (ANSI) Fibre Channel Tape (FC–Tape) Technical Report for the StorageTek implementation. FC–Tape Terms Allowed (A) Can be used between an initiator and a target (tape drive). For tape drives, this is typically dependent on the particular feature or parameter and its applicability to the request from an initiator.
Page 40: Loop Initialization Features
Loop Initialization Features Loop Initialization Features Arbitrated loop initialization protocol assigns up to a possible 126 addresses to different ports on the loop and builds a map of these addresses. The following pages describe some loop initialization features StorageTek tape drives perform. Loop initialization must occur before operations on the loop can begin.
Page 41: Loop Failures
Loop Initialization Features Loop Failures A loop failure is any of the following: • A loss of Signal • A loss of Synchronization for longer than R_T_TOV If a Loop Failure occurs, the L_Port which detects the failure issues a LIP(F8,AL_PS) if it has a valid AL_PA, or LIP(F8,F7) if it doesn’t.
Page 42: Loop Initialization Report Position
Loop Initialization Features Loop Initialization Report Position StorageTek tape drives support the mapping process to build a map of the AL_PA values according to their position on the loop. The temporary loop master begins the procedure to create a Loop Initialization Report (LIRP). This initialization report and map is done by using a 1-word frame identifier with an offset value of one (1).
Page 43: Fabric F_Port Attachment Initialization
Loop Initialization Features Fabric F_PORT Attachment Initialization In the absence of a loop environment the StorageTek tape drives will attempt to initialize with a fabric. This is accomplished by doing a Fabric Login (FLOGI). The FLOGI process will be attempted in each class of service that the tape drive supports. Once the FLOGI process is successful the tape drive will attempt to login (PLOGI) with the fabric attached name server, if it exists.

Sequence Management Exchange Responder The exchange responders assign unique RX_ID values or use the value of “FFFF.” The exchange responder considers an exchange open from the time it receives the first frame of the first information unit until one of the following occurs: •...
Page 60: Sequence Open
Sequence Management Sequence Open The tape drive considers a Sequence open from the time that the first frame of the Sequence (the frame with the SOFi3 delimiter) is sent until one of the following occurs: • An end-of-frame (EOF) delimiter is sent with the last sequence bit set •...
Page 61: Sequence Errors
Error Detection and Management Sequence Errors Sequence errors are managed as defined in FC–Tape with the following additions: 1. If a frame with an SOFi3 delimiter is received and the SEQ_CNT is not equal to zero or +1 from the SEQ_CNT of the last frame of the previous Sequence of that Exchange.
Page 62: 8B/10B Encoding And Decoding
Error Detection and Management • Successfully receiving write data by: • FCP Transfer Ready was received • A response was received However, FCP data and FCP responses cannot always be detected. Currently, the FCP-2 defines detection of these missing frames by using timeouts. For FCP responses, the target may request the initiator to send an FCP confirmation to confirm receipt of the response.
Page 63: Crc
Error Detection and Management Because the running disparity within a frame is variable, two different EOF delimiters are used depending on the content of the frame following the transmission of the CRC. TABLE 3-15 End of Frame Delimiters Delimiter Abbreviation Transmission Word Characters EOF Normal EOFn...
Page 64: Fibre Channel Timers
Fibre Channel Timers Fibre Channel Timers StorageTek tape drives use the timer values in TABLE 3-16. TABLE 3-16 Timer Summary Implemented By Timer Value Initiator Target StorageTek AL_TIME 15 ms R_T_TOV 100 ms E_D_TOV Private = 2 sec. (note 2) Public = supplied + 2 sec.
Page 65: Resource Allocation Timeouts
Fibre Channel Timers E_D_TOV includes the time required to gain access to the loop in addition to the actual frame transmission time. Resource Allocation Timeouts The Resource Allocation Timeout (R_A_TOV) has two components: • Sequence Qualifiers (SEQ_QUAL) defines the minimum time that an initiator waits before reusing the sequence qualifiers (SEQ_ID and SEQ_CNT).

Page 69: Command Information Unit
FCP Information Units Command Information Unit The Command Information Unit (T1) is a single-frame sequence. TABLE 3-19 FCP 8-Byte LUN Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 For all commands that transfer data to the tape drive: FCP_DL (data length) in the FCP_CMND payload always equals the number of bytes being transferred for the command.
Page 70: Data Information Unit
FCP Information Units For read operations: The FCP_XFER_RDY IU (I2) is not used during read type (data in) operations. This is indicated by setting the ‘READ XFER_RDY DISABLED’ bit during process login. Data Information Unit The Data Information Units (T6 and I3) are either single- or multiple-frame sequences.
Page 71: Table 3-20 Fcp_Rsp Payload
FCP Information Units Residual Checking Residual checking falls under the following categories: • SCSI Targets that transfer exactly FCP_DL data bytes during the FCP_DATA IUs set the FCP_RESID_UNDER to a value of ‘0’b. When FCP_RESID_UNDER is set to ‘0’b, the SCSI Initiator tries to determine if all of the expected data was transferred by comparing the FCP_DL to the actual number of bytes transferred.
Page 72: Table 3-21 Fcp_Rsp Codes
FCP Information Units Response Codes The Response Code field (FCP_RSP_INFO) contains information that describes the failures detected during the execution of an I/O Operation and conforms to the following rules: • The FCP_RSP_INFO does not contain link error information because FC-PH provides the mechanisms for presenting these errors.
Page 73: Task Management Flags And Information Units
FCP Information Units Task Management Flags and Information Units All SCSI Initiators send Task Management functions using T1. All SCSI Targets return FCP_RSP to Task Management functions using I4. The RSP_CODE in the FCP_RSP_INFO field indicates the result of the Task Management function.

Page 75: Busy
Status Byte Busy Busy (08) status occurs when the target: • Is busy performing another operation • Cannot accept a command The normal initiator recovery from a Busy status is to reissue the command. Check Condition Check Condition (02) status occurs when any error, unit exception, or abnormal condition that generates sense data occurs.
Page 76: Public Loop Scsi Target Discovery
Public Loop SCSI Target Discovery Public Loop SCSI Target Discovery The following private loop discovery is used except that discovery of SCSI Targets will be performed via the Simple Name Server or RSCN and the function performed by ADISC/PDISC will be replaced by FAN. Private Loop SCSI Target Discovery When the possibility of a configuration change exists, a SCSI Initiator may want to rediscover the new configuration.
Page 77 Private Loop SCSI Target Discovery Using this SCSI Target Discovery procedure, the SCSI Initiator has the ability to assemble a database consisting of Node name, Port name, and Port ID. There are several confirmations a SCSI Initiator can perform on that database to determine which SCSI Targets it can continue to communicate with that are not defined by this document.

Page 267: Glossary
Glossary This glossary defines terms and abbreviations used in this manual. For definitions of other Fibre Channel or StorageTek terms refer to the glossary in the appropriate document. Numbers 8B/10B A type of encoding and decoding algorithm of bytes, invented and patented by IBM, to reduce transmission errors.
Page 268 Acknowledge A response or confirmation to an address, message, or poll. Additional Sense Bytes The additional sense bytes contain data specific to either or both the command or peripheral device, and further define the nature of the FCP_SNS_INFO feature of the FCP_RSP payload.
Page 269 between more than two devices when those devices want to communicate on the bus. The sending device must arbitrate and win the connection with the receiving device before communication can begin. Arbitrated Loop Physical Address A one-byte value that identifies a port in an arbitrated loop topology. arbitration Any process by which a user of a shared resource negotiates with other users for the right to use the resource.
Page 270 Class of Service The Fibre Channel method of defining a data transmission strategy between devices. There are three FC Classes of Service currently specified in the FC-PH-1, and StorageTek’s implementation includes only one, Class 3. Class 3 The Fibre Channel Class of Service in which the initiator sends a message to a receiving device without expecting or requiring an acknowledgement.
Page 271 DF_CTL Data field control indicates optional headers in the frame. Disassembly The process of splitting out a source buffer into payloads. These payloads are then transmitted in frames. Discover Address (ADISC) The Discover Address command used in Extended Link Services. It is invokable when originated by the initiator, required as a response by the drive, and prohibited when originated by a drive.
Page 272 EOFn End of frame normal. EOFni End of frame normal invalid. EOFt End of frame terminate. Error Detect Timeout Value The minimum period of time that an L_Port can wait for the sequence to complete before initiating a recovery action. ESCON Enterprise Systems Connection.

Fiber is spelled “Fibre” in Fibre Channel. Fiber Distributed Data Interface (FDDI) An NCITS standard for transmitting data at 100 mega-baud over fiber optic cable.
Page 275 Frame An indivisible, encapsulated data structure containing a beginning-of-frame (BOF) and end-of-frame (EOF) designator, which carries a payload of both control data and user data from one FC port to another. Frame Header The first field in a frame that contains addressing information, as well as other control information, about the frame.
Page 276 host bus adapter (HBA) A circuit installed in a multi-platform host or device that interfaces between the device and the bus. HSSDC High speed serial data connectors. StorageTek tape drives use this type of connector at the interface card. A piece of hardware, separate from the actual FC interface accessible on the backplane of a device, which houses the port bypass circuitry for configurations of 8 to 16 ports per hub.
Page 277 Jitter The deviation of timing in an exchange. L_Port It is either an FL_Port or an NL_Port. Laser A term meaning Light Amplification by Stimulated Emission of Radiation. Laser devices generate coherent radiation in the visible, ultraviolet, and infrared portions of the electromagnetic spectrum.
Page 278 Login The FC-required process used by any initiating N_Port or NL_Port in an FC fabric to sign in with any other receiving N_Port or NL_Port port with which it plans to communicate. The signing in process provides the initiator with critical information about the attributes of the recipient port before it attempts to make a connection with Login_BB_Credit On an Arbitrated Loop, this signal is the value equal to the number of receive buffers...
Page 279 Mode Select Command The command used in Fibre Channel that specifies operational parameters and options for a logical unit. The fields that can be changed by the Mode Select Command and what the default values are for these fields. Most Significant Bit. multi mode A graded-index or step-index optical fiber that allows more than one bound mode to propagate.
