Page 15: General Description
OEM MANUAL:K6602771 Preface This manual describes the specifications of the Small Computer System Interface (SCSI) functions supported by the HITACHI 3 1/2 model magnetic disk drives. GENERAL DESCRIPTION APPLICATION This manual applies to the SCSI logical interface specification and Fibre Channel logical interface of the magnetic disk drive.
Page 16: Function Outline
OEM MANUAL:K6602771 FUNCTION OUTLINE The disk drive is connected to the host computer through the Fibre Channel Interface. The word “Controller” may be substituted for the disk drive since this manual describes only Fibre Channel interface functions which are implemented by the controller in the disk drive.
Page 17 OEM MANUAL:K6602771 COMMAND QUEUING One command per initiator(host computer) is enqueued(Untagged Command Queuing) and/or maximum 128 commands as total number of commands from all host computers are enqueued(Tagged Command Queuing). COMMAND RE-ORDERING The disk drive executes the multiple tagged commands with the advanced command re-ordering algorithm.
Page 18 OEM MANUAL:K6602771 (16) SECTOR INTERLEAVE A 1 : 1 interleave is supported. (17) SELECTABLE BLOCK LENGTH A 512 bytes block length is supported as a default and other block length is also available after the disk re-format. Refer to the Product Specification for details. (18) SMART(Self-Monitoring Analysis and Reporting) The SMART(Self-Monitoring Analysis and Reporting) function is supported.
Page 19: Glossary
OEM MANUAL:K6602771 GLOSSARY Bit number A number that represents the weighted position of one byte. Bit n represents a value of 2 n . Command Descriptor Block A command block that is used to communicate requests from (CDB) : an initiator to a target. , XXh A hexadecimal representation of a number (XX with a subscript H/h represents a hexadecimal number).
Page 20 OEM MANUAL:K6602771 L_Port A port connectable with FC-AL. (In Node, it is NL_Port. In Fabric,it is FL_Port) Circuit It is built by two arbitrary ports on FC-AL. Transmission of a frame is possible only among 2 ports which built the circuit.
Page 21: Product Specification Outline
OEM MANUAL:K6602771 PRODUCT SPECIFICATION OUTLINE This chapter describes the logical subjects of Product Specification. Refer to the Product Specification for physical information which are not included herein. ADDRESSING The host computer addresses the target logical unit (controller and drive) using the methods described below.
Page 22: 2.2.2 Format Processing
OEM MANUAL:K6602771 · Control parameters (MODE SELECT, INQUIRY and LOG) · Defect list (manufacture and grown) · Control program (Downloadable Firmware) etc. The data in system area is duplicated for data integrity. The user area consists of the diagnostic cylinder, the data area. The user area, except the data area, may not be accessible from the host computer.
Page 23 OEM MANUAL:K6602771 Alternate Spare Area The controller allocates 14 local alternate cylinders per notch as an Alternate Spare Area for the defective sector. Defect Management Defect management is the assignment of alternate spare sectors for defective sectors caused by media flaws. The host computer may access the data block as defect-free media by the defect management.
Page 24: Figure 2-1 Track Skew (Skew Factor N)
OEM MANUAL:K6602771 Figure 2-1 explains the details of Track Skew. Sector Sector Number Head 0 Head 1 n sectors Figure 2-1 Track Skew (Skew Factor n) Cylinder Skew The controller implements Cylinder Skew which shifts the sector array between cylinders ( i.e., between the last track of a cylinder and the first track of the next cylinder) to avoid a rotational latency when a 1 track seek is performed.
Page 25: Figure 2-3 Sector Reallocation
OEM MANUAL:K6602771 The replacement sector is assigned to the next defective sector, to reduce rotational latency. The controller executes a verification after formatting if C scheme is specified. If an error is found, the controller identifies the error sector as defective and reformats the track and the cylinder.
Page 26: Error Retry
OEM MANUAL:K6602771 · It is suggested to specify P, G and C schemes ( i.e., to use Primary and Grown lists, and to execute verify processing ) when specifying defect management. · The D scheme of defect management is not necessary for normal operation. Since the controller automatically reads P and G lists in system area and formats medium, the host computer does not need to specify the defect.
Page 27: 2.3.3 Verify Error Retry
OEM MANUAL:K6602771 2.3.3 VERIFY ERROR RETRY The controller performs the same retry as the read error retry mentioned in section 2.3.1 READ ERROR RETRY for the verify error during the verify operation. The host computer can change the error management of the controller with the verify error recovery parameter (Page Code 7 H ) of the MODE SELECT command.
Page 28: Supported Scsi Commands
OEM MANUAL:K6602771 ·However, if the error in the data field is correctable by ECC the controller corrects the error using ECC, and terminates the recovery procedure (this is applicable when EER=1). Retry Count The host computer can select the retry count by specifying the counts to the retry count field of the error recovery parameter.

If there are not FL_Port on the loop, NL_Port with the lowest Port_Name will become the temporary loop master. When FL_Port/NL_Port received LIP, they transmits LIP of the same type as received, and transmits Idle for AL_TIME (value for AL_TIME is 15ms).After each loop port has transmitted Idle for AL_TIME, each ports begins transmitting a loop initializing frame called the LISM frame...

If it in not set to 1, the L_Port shall set the bit to 1(unless a bit was set in LIFA or LIPA); if the bit is already set to 1, the ports on the Loop may attempt a Soft Assigned AL_PA.
Page 46: 3.3.3 Arbitrated Loop Access
OEM MANUAL:K6602771 3.3.3 ARBITRATED LOOP ACCESS This controller support the access fairness algorithm. In case that each NL_Port continuously arbitrates to access the loop, the lower priority NL_Ports cannot gain access to the loop. The access fairness algorithm gives all NL_Ports an opportunity to arbitrate and win access to the loop. When an NL_Port has arbitrated for and won access to the Loop and does not detect that another NL_Port is arbitrating, that NL_Port may keep the existing circuit open indefinitely or close that circuit and retain ownership of the loop to...
