3.0 Fixed-disk Subsystem Description
3.1 Control Electronics
The drive is electronically controlled by a microprocessor, logic modules, digital/analog modules and various drivers and
receivers. The control electronics perform the following major functions:
• Perform self-checkout (diagnostics)
• Conduct a power-up sequence and calibrate the servo.
• Monitor various timers for head settling, servo failure, etc.
• Analyze servo signals to provide closed-loop control. These include position error signal and estimated veloci ty.
• Control of the voice coil motor driver to align the actuator onto a desired position
• Monitor the actuator position and determine the target track for a seek operation.
• Constantly monitor error conditions of the servo and take corresponding action if an error occurs.
• Control starting, stopping, and rotating speed of the spindle.
• Control and interpretation of all interface signals between the host controller and the drive
• Control of read/write accessing of the disk media, including defect management and error recovery
3.2 Head Disk Assembly
The head/disk assembly (HDA) is assembled in a clean room environment and contains disks, a spindle motor, actuator assembly, and voice coil motor. Air is constantly circulated and filtered when the drive is operational. Venting of the HDA is accomplished via a breather filter.
The spindle is driven directly by a brushless, sensorless DC drive moto r. Dynamic braking is used to stop the spindle quickly.
3.3 Actuator
The read/write heads are mounted in the actuator. The actuator is a swing-arm assembly driven by a voice coil motor. A
closed-loop positioning servo controls the movement of the actuator. An embedded servo data pattern supplies feedback to the
positioning servo to keep the read/write heads centered over the desired track.
The actuator assembly is balanced to allow vertical or horizontal mounting without adjustment.
Heads are moved out from the disks (unloaded) to protect the disk data during shipping, moving, or storage. At power down,
the heads are automatically unloaded from over the disk area and the head actuator locking mechanism will secure the heads in
the unload position.

medium format and zone parameters for specific drives.
4.5 Performance characteristics
Drive performance is characterized by the following parameters:
•Command overhead
•Mechanical head positioning
- Seek time
•Data transfer speed
•Buffering operation (read ahead/write cache)
Note: All the above parameters contribute to drive performance. There are other parameters that contribute to the performance of the actual system. This specification tries to define the bare drive characteristics, not system throughput, which
depends on the system and the application.

Notes:
• Instantaneous disk-buffer transfer rate is derived by: (Number of sectors on a track) x 512 x (revolutions/sec)
• For this table, '1 MB / Sec' should be interpreted as 1,000,000 bytes per Second.
• The number of sectors per track will vary by zone because of the linear density recording.
• Sustained disk-buffer transfer rate is the average rate measured while transferring multiple cylinders of data. It differs from the instantaneous transfer rate because of the time required to change tracks (Cylinder skew and Head
skew). In addition, time is added for the occasional missed transfer.

5.0 Data Integrity
The drive retains recorded information under all non-write operations.
No more than one sector can be lost by power down during a write operation while write cache is disabled. If power down
occurs before completion of a data transfer from write cache to disk while write cache is enabled, the data remaining in the
write cache will be lost. To prevent this data loss at power off, the following action is recommended:
• Confirm successful completion of a SYNCHRONIZE CACHE (35h) command
5.1 Equipment Status
Equipment status is available to the host system any time the drive is not ready to READ, WRITE or SEEK. This status normally exists at power-on time and will be maintained until the following conditions are satisfied:
• Access recalibration/tuning is complete
• Spindle speed meets requirements for reliable operations
• Self-check of drive is complete
Appropriate error status is made available to the host system if any of the following conditions occur after the drive has
become ready:
• Spindle speed goes outside of requirements for reliable operation
• “Write fault” is detected
5.2 Error Recovery Procedure
Errors occurring with the drive are handled by the error recovery procedure.
Errors that are uncorrectable after application of the error recovery procedures are reported to the host system as non-recover-
able errors.

6.0 Physical Format
Media defects are remapped to the next available sector during the Format Process in manufacturing. The mapping from Logical Block Address (LBA) to the physical Block locations is calculated using internally maintained tables.
6.1 Shipped Format (P-List)
• Data areas are optimally used.
• All pushes generated by defects are absorbed by available tracks of the inner notch.
P-List Physical Format
Note: Defects are skipped without any constraint, such as track or cylinder boundary. The calculation from LBA to physical
is done automatically by internal table.
6.2 Reassigned Format (G-List)
• G-List has a capacity of 5000 Customer LBAs.
• Multiple reassignments of the same Customer LBA do not increase the number of G-List entries.
• A track for spare sectors is inserted after every 800 nominal customer tracks.

7.0 Electrical Interface
7.1 FC-AL Connector
The drive conforms to SFF specifications 8045, 8067 and 8451. The SFF 8045/8067 documents defines the electrical specification and SFF-8451 defines the mechanical specification. The only difference between SFF-8045 and SFF-8067 is the
Enclosure Service Interface. The drive will 'discover' the level of Enclosure Service Interface supported by the enclosure, and
use the proper level for enclosure communication. This 'discovery ' process is defin ed in the SFF-8067 specification.
The connector is expected to be used in an environment which uses a common connector structure for racking disk drives in a
cabinet. The connector allows for plugging a drive directly into a backplane by providing th e necessary electrical connection.
Mechanical stability and device retention must be provided by a mechanism outside the drive.
The signals defined in this connector include:
•Dual ported Fibre Channel In/Out control signals
• +5V and +12V power
• ID select
• Motor start control
• LED drive signals
• PBC Interlock control
• Fibre Channel link rate selection/Hard Reset
• Power control

7.1.2 Voltage and Ground Signals
The 12 V and 5 V contacts provide all of the voltages required by the drive. The two voltages share a common ground plane to
which all of the ground contacts are connected.
7.1.3 Fault LED Out
As specified in the SFF-8045 specification, the Fault LED is driven under the following conditions:
•both enable bypass signals are asserted by the drive
• an internal failure has been detected by the drive
• the drive has been instructed by the host to turn on the LED
The drive provides an open-collector TTL driver with up to 30mA of current sink capability to the drive fault LED. The cathode of the LED should be connected to this signal. The LED and the current-limiting resistor must be provided by the enclosure.
7.1.4 Ready LED Out
As specified in the SFF-8045 specification, the Ready LED Out signal has the following definition (per the Hot Plug Implementation):
• Drive not mated:
– The signal is de-asserted (i.e. high). The LED is off.
• Drive mated, motor not spinning:
– The signal is asserted (i.e. low) for a period long enough to be detected by the observer whenever a SCSI command is
received. The LED is normally off.
• Drive mated, spinning up or down:
– The signal is alternately asserted and de-asserted for a period of 1/2 second. The LED is flashing.
• Drive mated, motor spinning:
– The signal is normally asserted continuously. The signal is de-asserted for a period long enough to be detected by an
observer, whenever a SCSI command is received. The LED is usually on.
The drive provides an open-collector TTL driver with up to 30mA of current sink capability to the Ready LED Out signal. The
cathode of the LED should be connected to this signal. The LED and the current-limiting resistor must be provided by the
enclosure.

7.1.5 Start Mated Controls
The Start_X Mated signals are TTL inputs to the drive and have 10K ohm pull-up resistors.
As per the SFF-8045 specification, the 'Start_x Mated' function is implemented as in the following table. Please refer to SFF-
8045 for a more complete definition.
Table 13: Start/Mated Controls
Start_2 Mated Start_1 Mated Spin Function
Open Open Drive is not mated. No spin-up will occur.
Open Gnd The motor will spin up with the SCSI Unit Start Cmd
Gnd Open The motor will spin up after a delay of 6 times the modulo 8 of
Sel_ID (in seconds)
Gnd Gnd The motor will spin up after drive initialization
7.1.6 SEL_n and Enclosure Service Signals
These signals have different definitions depending on the state of -Parallel ESI and the level of enclosure service supported by
the backplane.
7.1.6.1 SEL_n and Enclosure Service Signals
-Parallel ESI is a TTL open-drain output from the drive. It is used to establish the definition of the SEL_n signals. When -Parallel ESI is de-asserted (high), the backplane shall preset SEL_ID information on these signals (within 1usec). When -Parallel
ESI is asserted (low), the backplane (if supported) will present enclosure service information on these signals (within 1usec).
The drive will then go through a 'discovery' phase to determine the level of enclosure services that the backplane supports (i.e.
none, SFF-8045, or SFF-8067) and behave accordingly.
7.1.6.2 SEL_ID Function
The SEL_n (TTL compatible) inputs (defined when -Parallel ESI is de-asserted) provide a binary value of loop identifier to the
drive. These 7 signals define 128 possible values and are directly translated into an 8 bit hard AL_PA via the table below . Only
AL_PA 's wi th neutral disparity are valid values. The drive will attempt to acquire this hard AL_PA for its own during the
LIHA phase of the loop initialization process (LIP).

Note: All values are in hex format. An AL_PA value of 0x00 is not valid for an NL_Port. A SEL_ID of 0x7F forces the
drive to obtain a soft address.
7.1.6.3 P_ESI_n Function
The SEL_N (TTL compatible) I/O's (defined when -Parallel ESI is asserted) provide an interface between the enclosure and
the drive. When signals are defined as outputs, they are configured as open-drain drivers with 4mA sink capability.
When the drive asserts -Parallel ESI, it goes through a 'discovery' process (see SFF-8067) to determine the level of enclosure
service supported by the backplane. The outcome of the 'discovery' process is that the backplane:
1. Does not support enclosure services or
2. Supports SFF-8045 enclosure services or
3. Supports SFF-8067 enclosure services
The definition of the signals are summarized in the table below:
Hitachi Ultrastar 15K450 (FC-AL) Hard Disk Drive Specification

Note: * level of backpl ane su pport as established in 'discovery'
** the direction is determined by the state of DSK_RD and DSK_WR
all signals are assumed valid 1 usec after -Parallel ESI changes state
7.1.6.4 SFF-8045 Enclosure Service Interface
The SFF-8045 Enclosure Service Interface defines 7 bits of enclosure status. This status is read by the drive, and presented to
the initiator, upon receipt of the appropriate SCSI RECEIVE DIAGNOSTIC command. The definitions of the status bits are
vendor specific. The drive does not try to interpret the status. The drive assumes -EFW is status and treats it as it does the other
P_ESI_n signals.
7.1.6.5 SFF-8067 Enclosure Service Interface
The SFF-8067 Enclosure Service Interface defines a bidirectional communication path between the backplane and the drive.
Read Communications are invoked by the drive upon receipt of the appropriate SCSI RECEIVE DIAGNOSTIC command.
This has the system level effect of the host reading information from the enclosure. Write Communications are invoked by the
drive upon receipt of the appropriate SCSI SEND DIAGNOSTIC command. This has the system level effect of the host writing information to the enclosure. The meaning of the information is vendor specifi c. The dri ve does not try to interpret the
information. See the SFF-8067 Specification for a detailed description of the communication protocol.
7.1.7 –ENBL_BYP CH1, -ENBL_BYP_CH2
These TTL outputs from the drive provide 4mA of sink capability. They are intended to control the state of a loop port bypass
circuit on the backplane. The drive powers up with these signals turned off. It is assumed that the backplane will provide a
1Kohm pull-down resistor that will ensure the drive is bypassed on the loop when it is not present, or when it is powering up.
After a successful power-up, the drive will attempt to enable itself on both loops (if allowed to do so via SCSI mode page 19h).
These signals are also controllable by the host with the LPB and LPE fibre channel primitives.
7.1.8 –Drive Present
This signal is connected to the drive's ground plane. The backplane can use this signal to detect the presence of the drive.
7.1.9 Dev_Ctrl_Code_x
The signals DEV_CTRL_CODE_2 through DEV_CTRL_CODE_0 provide a binary code to the drive to control functions
such as FC link rate, Power Failure W arning (PFW) and Hard Reset. The control function is either identified by a code or a
sequence of codes on the DEV_CTRL_CODE signals. The table below defines the functions and assigned codes that use a
Hitachi Ultrastar 15K450 (FC-AL) Hard Disk Drive Specification
23
Page 40
decode of the value on the DEV_CTRL_CODE signals.
The Hard Reset function uses a sequence of values on the DEV_CTRL_CODE signals. The sequence is 5, 1, 3, 2, 3, 1, 5. A
drive detecting a valid Hard Reset sequence shall perform the equivalent of a power-on-reset.
10 Kohm pull up resistors to 3.3 VOLTS are provided on the drive for both DEV_CTRL_CODE_ 2, DEV_CTRL_CODE_1
and DEV_CTRL_CODE_0 to be sure that each signal is maintained in its high state unless a low is provided from the backplane.
For more information refer to the SFF-8045 Specification.

9.2 Ripple Voltage
Table 20: Power Supply Generated Ripple at Drive Power Connector
Maximum (mV pp) MHz
+5 V DC 250 0-10
+12 V DC 250 0-10
During drive start up and seek, 12 volt ripple is generated by the drive (referred to as dynamic loading). If the power of several
drives is daisy chained, the power supply ripple plus other drive dynamic loading must remain within the regulation tolerance
of +5%. A common supply with separate power leads to each drive is a more desirable method of power distribution.
To prevent external electrical noise from interfering with the drive's performance, the drive must be held by four screws in a
user system frame that has no electrical level difference at the four screw positions. The drive enclosure must not be used in
the current return path of the drive power supply. The maximum common-mode noise current passing through the drive must
not exceed 20 mA.

No drive has more than one non-recoverable seek/ID miscompare error per 100 million seek operations (1 in 1x 10
operated at the full range of voltage and environmental conditions.
) when
10.4 Failure prediction (PFA/S.M.A.R.T)
A recoverable equipment error is an error other than a seek/ID miscompare error or read error that is detected and corrected by
the drive error recovery procedure. Examples are Write Fault, Drive Not Ready and internal drive errors.
SMART Monitoring Parameters are checked to determine if the (Read/Write/Seek) error rates exceed the drive’s threshold
value when an error occurs and a minimum amount of operation has been completed. A check is also performed for a minimum level of Spare Sector Availability.
The Head Load / Unload Count, Spin Up Time and Spin Up Retry Count parameters are checked prior to reporting a “Ready”
condition at Power On.
Non-recoverable equipment errors indicate a defective drive.
10.5 Preventive Maintenance

17.0 FC-AL attachment
This section defines some basic terminology and describes the behavior of the drive when attached to a Fibre Channel Arbitrated Loop.
17.1 Fundamentals
This section introduces some of the terminology that is used in describing Fibre Channel and FC-AL.
Fibre Channel is logically a bi-directional serial data channel between two Nodes. Nodes are physically connected by a Link;
the point of connection between the link and the node is called a Port.
Ports may be connected point-to-point by a single link or by a switching network (Fabric). If the port is part of the Fabric it is
called an F_Port, otherwise it is an N_Port.
Fibre Channel is defined in terms of a hierarchy of functions or 'protocol layers'.
• FC-0: Physical Link
• FC-1: Transmission Protocol
• FC-2: Signaling and Framing Prot ocol
• FC-3: Common Services
• FC-4: Mapping
All layers except FC-4 are defined in
• “Fibre Channel Physical and Signaling Interface (FC-PH)” - ANSI
The Arbitrated Loop is an extension of FC-1 and FC-2 that allows more than two nodes to be connected without the expense of
a Fabric. A port that connects to an Arbitrated Loop is generally referred to as an L_Port. However, the terms NL_Port and
FL_Port are also used if it is necessary to distinguish whether or not the L_Port is part of a Fabric. FC-AL is defined in:
• “Fibre Channel Arbitrated Loop (FC-AL)” -ANSI
FC-4, the Mapping layer, defines how other communication protocols (e.g. SCSI, IPI-3, HIPPI) may use Fibre Channel functions. The FC-4 used by The Drive is SCSI-FCP, which is defined in:
• “Fibre Channel Protocol for SCSI (SCSI-FCP)” -ANSI
The 'Disk Profile', recommends which features from the other documents should and should not be implemented in order to
ensure compatibility between devices from different manufacturers. The full title of the Disk Profile is:
• “Fibre Channel Private Loop SCSI Direct Attach (F C- PLDA)” -ANSI
An additional document, the ‘Public Loop Profile’, describes the additional features needed to support communication over a
FC Fabric Topology. In addition to communicating with devices on their local loop, Public Loop devices can also communicate to devices across a network through the use of a “Fabric Port.” Public Loop behavior is defined in:
• “Fibre Channel - Fabric Loop Attach (FC-FLA)” -ANSI
The Drive complies with the FC-FLA, which makes the following requirements:
1. The upper two bytes of the device’s NL_Port ID must not be zero.
2. The device must be able to communicate with the Fabric Port i.e., open AL_PA 0x00.
Hitachi Ultrastar 15K450 (FC-AL) Hard Disk Drive Specification
53
Page 70
In addition, the Drive implements FC-FLA as a super-set of the FC-PLDA. Thus, the Drive conforms to FC-PLDA except for
those behaviors explicitly defined by the FC-FLA profile. The PLDA makes the following additional requirements.
1. The FC-4 is SCSI-FCP.
2. The Drive provides a Class 3 Fibre Channel service.
- NO indication of (un)successful class 3 frame delivery is transmitted.
- Frame flow control is buffer-to-buffer only.
- Class 1 and 2 frames are ignored.
3. Direct point-to-point attachment with an N_Port is not supported.
17.1.1 Node and Port names
Every Fibre Channel Node and Port in the world must have a unique name. The Drive is a node with two L_Ports and therefore
has a Node_Name and two Port_Names.
Both the Node_Name and Port_Name are in 64-bit IEEE Registered Name format, as illustrated in Table 24.
Table 24: IEEE Registered Name format
Bit
63-60 59-36 35-24 23-2 1-0
0101 OUI in Canonical Form Block Assignment S/N Object
The Name Address Authority field (0101b) specifies the format used for the rest of the name as follows:

17.1.2 NL_Port address
An NL_Port address, as illustrated in Table 25, is a 3 byte value that uniquely identifies an NL_Port on a Fibre Channel network. The Domain and Area bytes are assigned to a NL_Port by its local FL_Port. The least significant byte in the NL_Port
address is the Arbitrated Loop Physical Address (AL_PA), and uniquely identifies a NL_Port on its local loop.
A Hard AL_PA is one which is supplied, via the Drive connector, from external switches or jumpers. A Soft AL_PA is one
which is assigned during Loop Initialization

17.1.3 Primitive signals and sequences
The fundamental unit of transfer on a Fibre Channel link is the 8b/10b encode d Transmission Character. Only 256 characters
are required to represent a byte of data so the set of valid transmission characters is sub-divided into Data Characters and Special Characters.
A Word is a group of four consecutive transmission characters.
An Ordered Set is a word that starts with a special character (to give word and byte sync) and which has special significance to
the communication protocol. Fibre Channel defines the following types of ordered sets:
• Frame delimiters
• Primitive signals
• Primitive sequences
A Frame Delimiter immediately precedes or follows the contents of a frame (see 17.1.4, “Frames” on page 56). Fibre Channel
defines the following:
•SOF Start of frame
•EOF End of frame
A Primitive Signal is an ordered set that has special meaning when received by itself. Fibre Channel defines the following:
• R_RDY Receiver Ready
• IDLE Idle
FC-AL adds the following:
• ARBx Arbitrate
• ARB(F0) Arbitrate
•OPNyx Open Full-duplex
•OPNyy Open Half-duplex
•OPNfr Open Broadcast Replicate
•OPNyr Open Selective Replicate

•CLS Close
•MRKtx
Mark

A Primitive Sequence is an ordered set that is transmitted repeatedly and continuously. Three or more of the ordered sets must
be received consecutively in order to recognize the primitive sequence. Fibre Channel defines the following:
•NOS Not Operational
•OLS Offline
2
•LR Link Reset

2
• LRR Link Reset Received2
FC-AL adds the following:
•LPByx Loop Port Bypass
• LPEyx Loop Port Enable
1. Since normal buffer-to-buf fer flow control is disabled when OPNr is used, there is no guarantee that the drive has a buffer available to receive an
in-bound frame. It is therefore, recommended that OPNr not be used.
2. Used to convey information about a dedicated connection and therefore not relevant to FC-AL. If detected during an open connection, the drive
will immediately close. Otherwise it will simply re-transmit.

17.1.4 Frames
Information transfer is achieved via frames that are constructed from words and ordered sets. All frames have the same general
format, as shown in Table 26.
Table 26: General frame format
Field name SOF Header Payload Fill bytes CRC EOF
Field size, # of bytes 4 24 0 to 2048 0 to 3 4 4
The SOF ordered set indicates the start of frame and provides word synchronization.
The Header is the first field after the SOF delimiter. It is used by the link control facility to control link operations, control
device protocol transfer, and to detect missing or out of order frames. The header is illustrated in Table 27.
FC-PH describes the content of each field except 'Parameter'. SCSI-FCP defines this field as RLTV_OFF (Relative Offset).
Table 27: Frame header
Byte
word
0 R-CTL D-ID
1 Reserved S-ID
2 TYPE F-CTL
3 SEQ-ID DF-CTL SEQ-CNT
4 OX-ID RX-ID
5 Parameter (RLTV_OFF)
The Payload follows the header and has a length between 0 and 2048 bytes, which must be divisible by 4. An additional 0-3
fill bytes are appended to the payload in order to ensure that it ends on a word boundary.
The Cyclic Redundancy Check (CRC) is a four byte field following the payload. It is used to verify the integrity of the header
and payload.
The EOF ordered set marks the end of a frame.
3210
17.1.5 Sequences
A Sequence is a set of one or more related frames that flow in one direction only. The sequence is identified by the Sequence
Identifier (SEQ_ID) field in the frame header.
Hitachi Ultrastar 15K450 (FC-AL) Hard Disk Drive Specification
56
Page 73
17.1.6 Exchanges
An Exchange is a set of one or more related non-concurrent sequences that may flow in the same or opposite directions. The
exchange is identified by an Originator Exchange Identifier (OX_ID) and a Responder Exchange Identifier (RX_ID) in the
frame header.
17.2 Basic Link Services
The Basic Link Services are all frames with no payload. The Header TYPE field is set to 00h (Basic Link Service) and R_CTL
is set to 1000xxxxb (Basic Link_Data, Code = xxxx).
Table 28: Basic link service command codes
Command Description Abbr.
0000 No Operation NOP
0001 Abort Sequence ABTS
0010 Remove Connection RMC
0100 Basic Accept BA_ACC
0101 Basic Reject BA_RJT
Others Reserved
NOP and RMC are prohibited by the Disk Profile. If the drive receives either an NOP or an RMC, it will ignore it.
Note: PLDA 2.1 specifies: “Reserved FC-PH fields are not required to be checked for zeroes. Validity bits set to 0 remove any
requirement to check the corresponding field for zeroes (e.g., if F_CTL bit 3=0, receiving N_Ports are not required to verify
that the parameter field in word 5 of the frame header contains zeroes).” As such, the drive does not validate 1) reserved FC
fields or 2) fields that are not reserved but are not valid for the current frame (as the example above with F_CTL bit 3). This
does not apply to any reserved field checking and testing within the FCP_CDB. These fields are checked as per ANSI SCSI
requirements.
17.2.1 Abort sequence (ABTS)
Although ABTS is a Fibre Channel Basic Link Service, it is used by SCSI-FCP to implement the Abort Task, Task Management function. It may only be used by a SCSI initiator to abort an entire exchange using the Recovery Abort protocol. Refer to
18.4.1, “Abort Task (Implemented as ABTS BLS)” on page 111 for a description of the Recovery Abort Protocol and the
frame payloads.
The response to ABTS is either BA_ACC or BA_RJT.

Page 74
17.2.2 Basic accept (BA_ACC)
BA_ACC indicates that a Basic Link Service Request has been completed. The drive only sends a BA_ACC in response to an
ABTS Basic Link Service.

• SEQ_ID Validity specifies whether the SEQ_ID field in the BA_ACC payload is valid or not. The drive always sets
this field to 00h.
• SEQ_ID specifies the last SEQ_ID which is deliverable to the Upper Level Protocol. Since the drive uses the ABTS
protocol to abort an entire exchange, this field is unused. The drive sets this field to 00h.
• OXID specifies the OXID of the exchange that has been aborted by the drive.
• RXID specifies the RXID of the exchange that has been aborted by the drive.
• Low SEQ_CNT specifies the last data frame of the last delivered sequence. Since the drive aborts the entire
exchange, this field is set to 0000h.
• High SEQ_CNT is only valid when an ABTS is used to abort a single sequence. Since the drive only supports abort-
ing of entire exchanges, this field is set to 0000h.

17.3 Extended Link Services
For Extended Link Service frames, the Header TYPE field is set to 01h (Extended Link Service). R_CTL is either 22h
(Extended Link Data, Unsolicited Control) for a Request, or 23h (Extended Link Data, Solicited Control) for a Reply.
The first byte of the payload is the LS_Command and encodes the Request or Reply, as shown in Table 33 and Table 34.

Note: Only lists ELSs supported by the drive. Refer to FC-PH for a complete list of ELSs.
The code '11h' for the TEST ELS (not supported by the drive) is also used by the LIPxx frames that circulate during Loop Initialization. To differentiate these from a TEST ELS, the second byte of the payload must be examined and compared with
Table 35.
Note: PLDA 1.10 specifies: “Reserved FC-PH fields are not required to be checked for zeroes. Validity bits set to 0 remove
any requirement to check the corresponding field for zeroes (e.g., if F_CTL bit 3=0, receiving N_Ports are not required to verify that the parameter field in word 5 of the frame header contains zeroes).” As such, the drive does not validate 1) reserved FC
fields or 2) fields that are not reserved but are not valid for the current frame (as shown in the example above with F_CTL bit
3). This does not apply to any reserved field checking and testing within the FCP_CDB. These fields are checked as per ANSI

If a Loop Initialization frame is received when the Port is not performing a Loop Initialization Procedure, it will be responded
to by an LS_RJT containing a reason code of “Command not supported” and a reason code explanation of “No addit ion al
explanation”. This also applies to all unsupported link services, as defined by Table 34.
17.3.1 Link Service Accept (LS_ACC)
LS_ACC is used in response to an Extended Link Service Request. It indicates that the request has been completed.
The LS_ACC payload depends upon the Extended Link Service Request and is therefore described separately for each of the
following:
17.3.3 “Port Login (PLOGI)”
17.3.4 “Logout (LOGO)”
17.3.5 “Fabric Login (FLOGI)”

Note: Refer to FC-PH for a full list. Only the explanations relevant to supported Extended Link Services are shown.
17.3.3 Port Login (PLOGI)
PLOGI is used by the Initiator to register Service Parameters with the Target if Implicit Login is not being used (see 19.10.12,
“Mode Page 19h (Fibre Channel Port Control Page)” on page 190). The Target responds with an LS_ACC that has a payload
similar to the PLOGI but which contains the Targets parameters. This exchange of parameters establishes the operating environment between the Initiator and the Target.
PLOGI can also be issued by the Target when it is operating as a Public Loop Device. In this case, the T arget uses a PLOGI to
establish the operating environment between it and the Fabric Name Server.
Bytes 1, 2, and 3, of the payload must be set to zeros. Otherwise, the drive will respond with an LS_RJT containing a reason
code of “Command not supported”, and a reason code explanation of 00h “No additional explanation”.

The BB_Credit field indicates the number of frame buffers that a port guarantees to have immediately available when a loop
circuit is opened. The drive returns 0 (zero) in this field; i.e., every Initiator is given a Login BB_Credit of 0.
The Common Features field contains flags.
• CIO - Continuously Increasing Offset
When set to one, this flag indicates that the Port supports Continuously Increasing Relative Offset within a Sequence
on a frame by frame SEQ_CNT basis. The Relative Offset is only present if bit 3 of the F_CTL field in the frame
header is set to 1b. The drive requires that an initiator support Continuously Increasing Relative Offset. If this field is
Hitachi Ultrastar 15K450 (FC-AL) Hard Disk Drive Specification
66
Page 83
not one, the drive will respond with an LS_RJT containing a reason code of 03h “Logical error”, and a reason code
explanation of 0Fh “Invalid Common Service Parameters”. The drive returns a 1b in this field.
• RRO - Random Relative Offset
When set to one, this flag indicates that the Port supports Random Relative Offset within a Sequence. The Relative
Offset is only present if bit 3 of the F_CTL field in the frame header is set to 1b. The drive returns a 0b in this field.
• VV - Valid Vendor Version Level
When set to one, this flag indicates that the Vendor Version Level field in th e frame pa yload contains valid informa-
tion. The drive returns a 0b in this field.
• N/F Port - N_Port/F_Port
When set to one, this flag indicates that the Port is an F_Port. When set to zero, it is an N_Port. The drive returns a 0b
in this field.
• ABCM - Alternate BB-Credit Model
When set to one, this flag indicates that the Port supports the Alternate BB-Credit mo del. The drive returns a 1b in
this field.
• E_D_TOV - E_D_TOV Resolution
When set to one, this flag indicates that the resolution of the E_D_TOV timer shall be 1 ns. When set to zero, the res-
olution shall be 1 ms. The flag is only applicable in a point to point topology. The drive returns a 0b in this field.
• DS - Dedicated Simplex
Only applies to class 1 service. The drive sets this field to 0b.
• DHD - Dynamic Half Duplex
When set to one, this flag indicates that the Port supports Dynam ic Half Duplex. The drive returns a 0b in this field.
•SEQ_CNT - SEQ_CNT
When set to one, this flag indicates that the Port is guaranteeing that it will transmit all frames within an Exchange
using a continuously increasing SEQ_CNT. If set to zero, normal FC_PH rules regarding SEQ_CNT usage apply. The
drive returns a 0b in this field.
• PL - Payload Length
When set to one, this flag indicates that PLOGI Payload Length shall be 256 bytes. If set to zero, the flag specifies
that the normal 116 byte PLOGI Payload specified in FC-PH-2 is used. The drive returns a 0b in this field.
The Buffer-to-Buffer Receive Data_Field Size field (word 2, bits 11-0) specifies the largest FT_1 frame Data_Field Size that
may be received by the Nx_Port supplying the Service Parameters as a Sequence Recipient for:
a) a connect-request (SOFc1),
b) a Class 2 Data frame, or
c) a Class 3 Data frame
Values less than 256 or greater than 2 112 are invalid and shall be a multiple of four bytes. An Fx_Port shall support a Data
Field size of at least 256 bytes.
The Total Concurrent Sequences field indicates the number of concurrent sequences that the Port can support for all 3
classes. The value sent must be > 0, or the drive will respond with an LS_RJT with a reason code of 03h “Logical error” and a
reason code explanation of 09h “Service Parm error - Concurrent Seq”. The drive returns a value of FFh in this field.
The Relative Offset by Information Category field is all flags. The bit position of each set (1) bit determines the Information
Category; e.g., if Relative Offset is supported for category 0001b (Solicited Data), bit 1 is set. The drive returns a value of
0002h in this field (Relative Offset supported for Solicited Data only).
Hitachi Ultrastar 15K450 (FC-AL) Hard Disk Drive Specification

Page 84
The E_D_TOV field specifies the E_D_TOV (Error Detect Timeout Value) in units of 1ns or 1ms. If the E_D_TOV Resolution bit is set to one, this field specifies E_D_TOV as a count of 1ns increments, otherwise it specifies E_D_TOV as a count of
1ms increments. It is only applicable in a point to point topology. The drive returns zero in this field. It is not interpreted or
checked.
17.3.3.2 Class Service Parameters
Since the drive only supports Class 3 service, it only checks and responds to the Class 3 Service Parameters.

17.3.5 Fabric Login (FLOGI)
FLOGI is used by the drive to register its Service Parameters with the Fabric assuming the drive exists on a Public Loop (i.e.
the loop contains an FL_Port). Once the drive has completed FLOGI, it is then permitted to use the local FL_Port as a gateway,
allowing it to communicate with other N_Ports and NL_Ports attached to the fabric. (See 21.5, “Public Loop Operation” on
page 312.)
The drive performs a FLOGI by opening a full duplex connection to FL_Port located at AL_PA 00h and sending a FLOGI
request to the well-known address of FFFFFEh. The FL-Port responds to a valid request with a FLOGI Accept frame that contains the FL_Port’s operating parameters. The D-ID field of the FLOGI Accept frame contains the fabric assigned Domain,
Area, and the AL-PA of the drive perform in g the FLOGI. The drive uses this address in all further communication with other
N_Ports and Public NL_Ports. The drive will not perform a FLOGI if the drive fails to detect an FL_Port during Loop-Initialization.

The upper byte of the FC-PH Version field indicates the highest version of FC-PH that is supported and the lower byte indicates the lowest. The code/version relationship is given by Table 42.
The BB_Credit field indicates the number of frame buffers that a port guarantees to have immediately available when a loop
circuit is opened. The drive sets this field to 0 (zero); i.e., the drive grants the FL_Port a Login BB_Credit of 0.
The Common Features field contains the following flags:
• VV- Valid Vendor Version Level
When set to one, this flag indicates that the Vendor Version Level field in th e frame pa yload contains valid informa-
tion. The drive sets this field to 0b.
• N/F Port - N_Port/F_Port
When set to one, this flag indicates that the Port is an F_Port. When set to zero, it is an N_Port. The drive checks this
field in the FLOGI_ACC and will revert to PLDA behavior if it is not set to one. The drive sets this field to 0b.
Hitachi Ultrastar 15K450 (FC-AL) Hard Disk Drive Specification

Page 90
• ABCM - Alternate BB-Credit model
When set to one, this flag indicates that the Port supports the Alternate BB-Credit model. As per the FC-AL Specifi-
cation, an L_Port and must support the Alternate BB-Credit model. The drive checks the value returned by the
FL_Port and will revert to PLDA behavior if it is not set to one. The drive sets this field to 1b.
• DHD - Dynamic Half Duplex
When set to one, this flag indicates that the Port supports the Dynamic Half Duplex. The drive sets this field to 0b.
• PL - Payload Length
When set to one, this flag indicates that FLOGI Payload Length shall be 256 bytes. If set to zero, the flag specifies
that the normal 116 byte FLOGI payload specified in FC-PH-2. The drive sets this field to 0b.
The Buffer to Buffer Receive Data Field size indicates the largest frame payload (in bytes) that the Port can receive. Sizes
less than 128, greater than 2112, or not divisible by 4 are invalid. The drive check this field in the FLOGI_ACC payload and
will revert to PLDA behavior if an invalid value is returned. The drive sets this field to 2048.
The R_A_TOV field specifies the R_A_TOV (Resource Allocation T imeout Value) supplied by the fabric in units of 1ms. The
fabric port sets this field in its FLOGI_ACC payload. This field is reserved in the FLOGI_REQ and the drive therefore sets
this field to zero. After FLOGI is complete, the drive will use this value for R_A_TOV until the drive is reset, reverts to PLDA
behavior, or performs another FLOGI.
The E_D_TOV field specifies the E_D_TOV (Error Detect Timeout Value) supplied by the fabric in units of 1ns or 1ms. The
fabric port sets this field in its FLOGI_ACC payload. This field is reserved in the FLOGI_REQ and the drive therefore sets
this field to zero. After FLOGI is complete, the drive will use this value for E_D_TOV until the drive is reset, reverts to PLDA
behavior, or performs another FLOGI.

• SD - Sequential Delivery
The drive sets this field to 1b to request that the fabric deliver all frames in the same order they were transmitted. The
fabric sets this flag to 1b if it can honor this request. Since the drive does not support out of order frame delivery, the
drive checks the FLOGI_ACC to ensure that this field is set to 1b and will revert to PLDA behavior if it is not.
• DS - Dedicated Simplex
This flag only applies to class 1 service. The drive sets this field to 0b.
• Camp On - Camp-On
This flag only applies to class 1 service. The drive sets this field to 0b.
• BufC1 - Buffered Class 1
This flag only applies to class 1 service. The drive sets this field to 0b.
• Priority - Priority
This flag does not apply to class 3 service. The drive sets this field to 0b.
The Initiator Control Flags are not meaningful for FLOGI and are therefore reserved. The drive sets this field to 00h.
The Recipient Control Flags are not meaningful for FLOGI and are therefore reserved. The drive sets this field to 00h.
The Receive Data Field Size field is not meaningful for FLOGI and is therefore reserved. The drive sets this field to 00h.
The Concurrent Sequences field is not meaningful for FLOGI and is therefore reserved. The drive sets this field to 00h.
The End-to-End Credit field is not meaningful for FLOGI and is therefore reserved. The drive sets this field to 00h.
The Open Sequences per Exchange field is not meaningful for FLOGI and is therefore reserved. The drive sets this field to
00h.
The Class 6 Multi-cast RXID field is not meaningful for FLOGI and is therefore reserved. The drive sets this field to 00h.
17.3.6 Fabric Address Notification (FAN)
The FAN ELS is sent by an FL_Port to all previously logged in (FLOGI) NL_Ports after an initialization event has occurred.
An initialization event can be a LIP or any other event that may cause a Port to change its ID. The FAN ELS is used by
attached NL_Ports to validate their operating parameters with the local FL_Port after an initialization event has occurred. The
drive does not return a response to this ELS.
(Note: When operating as a private loop device, the drive will discard the FAN ELS request.)

The Fabric Port Name is the world-wide-unique 8-byte Port_Name of the local FL_Port.
The Fabric Name is the world-wide-unique 8-byte name of the Fabric.
17.3.7 Port Discovery (PDISC)
An Initiator uses PDISC to exchange service parameters without affecting the operating environment between it and the drive.
The PDISC and corresponding ACC payloads are exactly as defined for PLOGI (see 17.3.3, “Port Login (PLOGI)” on page
63), except that byte 0 of the payload is 50h. It can be used as a means of authentication following a Loop Initialization process. If AL_PA's of the Initiator an d Target have not changed since the previous login, the Initiator and Target can continue
where they left off prior to the LIP and all open exchanges will continue. If the current AL_PA's do not match the login values,
the drive will implicitly log out the Initiator.
If some means of authentication following a LIP does not occur within RR_TOV, the drive will implicitly log out the Initiator.
Bytes 1, 2, and 3 of the payload must be set to zero. Otherwise, the drive will respond with an LS_RJT containing a reason
code of 0Bh “Command not supported” and a reason code explanation of 00h “No additional explanation”.
17.3.8 Address Discovery (ADISC)
The ADISC ELS allows communicating N-Ports to exchange addresses and port/node name identifiers. It can be used as a
quick means of authentication following a Loop Initialization process. If the AL_PA's of the Initiator and Target have not
changed since the previous login, the Initiator and Target can continue where they left off prior to the LIP, and all open
exchanges will continue. If the current AL_PA's do not match the login values, the drive will implicitly log out the Initiator.
ADISC can also be used as a means to determine if a port was able to acquire its hard AL_PA during LIP.
Bytes 1, 2, and 3 of the payload must be set to zero. Otherwise, the drive will respond with an LS_RJT containing a reason
code of 0Bh “Command not supported” and a reason code explanation of 00h “No additional explanation”.
If some means of authentication following a LIP does not occur within RR_TOV, the drive will implicitly log out the Initiator.
The following tables show the ADISC payload and the ADISC ACC payload.

Hard Address: This 3 byte identifier consists of:
• The MSB is an 8-bit domain address. If the drive is acting as a Public Loop Device, it returns the domain address
given to it by the Fabric port during login. Otherwise the drive returns 0s in this field.
• The middle byte is an 8-bit area address. If the drive is acting as a Public Loop Device, it returns the area address
given to it by the Fabric port during login. Otherwise the drive returns 0s in this field.
• The LSB is the 8-bit AL_PA that the port attempts to acquire during the LIHA sequence of LIP. For the drive, this
number is calculated from the SEL-ID pins on the SCA-2 backplane connector.
When the Hard Address field is equal to the N_Port ID field, the port was able to obtain its hard address during LIP . The drive
does not check the value sent from the originator.
Port Name: IEEE unique address assigned during the manufacturing process.
Node Name: IEEE unique address assigned during the manufacturing process.
N_Port ID: This is the 24-bit NL_Port Identifier used in the S_ID of the ADISC Accept header. The lower 8 bits are the
AL_P A the drive acquired during loop initialization, and the upper 16 bits are the domain and area addresses the drive obtained
from the Fabric port. For private devices the upper two bytes should be all 0s. When this field matches the Hard Address field,
the drive was able to acquire its hard AL_PA during LIP.

17.3.11 Read Link Error Status Block (RLS)
RLS requests the recipient to return the Link Error Status Block associated with the Port Identifier specified in the payload.
The drive implements a Link Error Status Block for each port. When a counter overflows, it wraps back to zero. The only way
to reset the Link Error Status Block is to po w e r off the drive.
Bytes 1, 2, and 3 of the payload must be set to zero. Otherwise, the drive will respond with an LS_RJT with a reason code of
“Command not supported” and a reason code explanation of “No additional explanation”.
Valid Port Identifiers are:
0 Return the Link Error Status Block for the same port on which the request was received.
1 Return the Link Error Status Block for Port A.
2 Return the Link Error Status Block for Port B.
