The design characteristics of the drive serve to minimize radiation when installed in an enclosure that provides reasonable shield ing. As such, t he dr ive is cap able of me eting th e C lass B l imit s of the FC C Rules a nd R eg ulations of the Canadian Department of Communications when properly packaged. However, it is the user’s responsibility to assure that the drive meets the appropriate EMI requirements in their system. Shielded I/O cables may be required if the enclosure does not provide adequate shielding. If the I/O cables are external to the enclosure, shielded cabl es sh ould be u sed, wi th the shields gr ounde d to the enclosur e and to the host co ntroller.

2.1.1.1 Electromagn etic susc ept ibili ty

As a component assembly, the drive is not required to meet any susceptibility performance requirements. It is the responsibility of those integrating the drive within their systems to perform those tests required and design their system to ensure that equipment operating in the same system as the drive or external to the system does not adversely affect the performance of the drive. See Table 2, DC power requirements.

3.0 General description

Savvio drives combine Tunneling Magnetoresistive (TMR) he ads and a Fibre Channel inter face to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainf rames , and super comp uter s. Savvio dr i ves also s uppor t 2- Gbit F ib re Ch annel whi ch can tran sfer data at up to 200 Mbytes per second and 400 Mbytes per second in dual-loop configurations.

Savvio drives support the Fibre Channel Arbitrated Loop (FC-AL) and SCSI Fibre Channel Protocol as described in the ANSI specifications, this document, and the Fibre Channel Interface Manual (part number

77767496) which describes the general interface characteristics of this drive. Savvio drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard.

Never disassemble the HDA and do not attempt to service items in the sealed enclosure (heads, media, actuator, etc.) as this requires special facilities. The drive does not contain user-replaceable parts. Opening the HDA for any reason voids your warranty.

Savvio drives use a dedicated landing zone at the innermost radius of the media to eliminate the possibility of destroying or de grad i ng d at a b y l and ing in the data zone. Th e h eads autom atical ly go t o the landing zone when power is removed from the drive.

An automatic shipping lock prevents potential damage to the heads and discs that results from movement during shipping and handling. The shipping lock disengages and the head load process begins when power is applied to the drive.

The drives also use a high-performance actuator assembly with a low-inertia, balanced, patented, straight arm design that provides excellent performance with minimal power dissipation.

3.5 Formatted ca pacities

St an dard OEM mo del s ar e formatte d to 512 bytes per block. The sector size is sel ect ab le at fo rma t time. Users having the necessary equipment may modify the data block size before issuing a format command and obtain different formatted capacities than those listed.

Note. For 2 gigabit operation, sector sizes must be divisible by 8. To provide a stable target capacity environment and at the same time provide users with flexibility if they

choose, Seagate recommends product planning in one of two modes:

1. Seagate desig ns specify cap acity po i nt s at cert ain sect or si zes tha t Seagate gu ara ntees cur ren t and futu re

products will meet. We recommend customers use this capacity in their project planning, as it ensures a stable operating point with backward and forward compatibility from generation to generation. The current guaranteed operating points for this product are:

2. Seagate drives also may be used at the maximum available capacity at a given sector size, but the excess

capacity above the guaranteed level will vary between other drive families and from generation to generation, depending on how each sector size actually formats out for zone frequencies and splits over servo bursts. This added capacity potential may range from 0.1 to 1.3 percent above the guaranteed capacities listed above. Using the drives in this manner gives the absolute maximum capacity potential, but the user must determine if the extra capacity potential is useful, or whether their assurance of backward and forward compatibility takes precedence.

3.5.1 Programmable drive capacity

Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select (6) parameter list table in the Fibre Channel Interface Manu al, part number 7767496. Refer to the Parameter list block descriptor number of blocks field. A value of zero in the number of blocks field indicates that the drive shall not change the capacity it is currently formatted to have. A number in the number of blocks field that is less than the maximum number of LBAs changes the total drive capacity to the value in the block descriptor number of blocks field. A value greater than the maximum number of LBAs is rounded down to the maximum capacity.

If a recoverable error conditio n i s detect ed dur ing the sta rt seq uence, the dr i ve execu tes a re cover y proce dure and the time to become ready may exceed 20 seconds. Stop time is 30 seconds (maximum) from removal of DC power.

If the Motor Start option is enabled, the internal controller accepts the commands listed in the Fibre Channel Interface Manual less than 3 seconds after DC power has been applied. After the Motor Start command has been received, the drive becomes ready for normal operations within 20 second s (excluding the err or reco very procedure). The Motor Start command can also be used to command the drive to stop the spindle.

There is no power control switch on the drive.

Savvio FC Product Manual, Rev. D

4.4 Prefetch /m ulti-segmen te d ca ch e control

The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can enhance system performance. Cache refers to the drive buffer storage space when it is used in cache operations. To select this feature, the host sends the Mode Select command with the proper values in the applicable bytes in page 08h. Prefetch and cache operations are independent features from the standpoint that each is enabled and disabled independently using the Mode Select command; however, in actual operation, the prefetch feature overlaps cache operation somewhat as described in sections 4.5.1 and 4.5.2.

All default cache and prefetch mode parameter values (Mode Page 08h) for standard OEM versions of this drive family are given in Table 17.

4.5 Cache operation

Note. Refer to the Fibre Ch anne l Interface Manual for more detail concerning the cache bits.

Of the 8,192 Kbytes physical buffer space in the drive, approximately 7,100 Kbytes can be used as a cache. The buffer can be divi ded into log i cal segm ent s (u sing M ode S elect Pa ge 08 h, byte 13) from which data is read and to which data is written.

The drive keeps track of the logical block addresses of the data stored in each segment of the buffer. If the cache is enabled (see RCD bit in the Fibre Channel Interface Manual ), data requested by the host with a read command is retrieved from the buffer, if possible, before any disc access is initiated. If cache operation is not enabled, the buffer (still segmented with the required number of segments) is still used, but only as circular buffer segments during disc medium read operations (disregarding Prefetch operation for the moment). That is, the drive doe s not ch eck in th e buffer segments fo r the req uested read data, but go es di re ctly to th e medium to retrieve it. The retrieved data merely passes through some buffer segment on the way to the host. On a cache miss, all data transfers to the host are in accordance with buffer-full ratio rules. On a cache hit, the drive ignores the buffer -ful l rat io rul es. See the exp lanati on provide d with the infor mation about Mo de P age 02h (disconnect/reconnect control) in the Fibre Channel Interface Manual.

The following is a simplified description of the prefetch/cache operation: Case A—read command is received and the first logical block is already in the cache:

1. Drive transfers to the initiator the first logical block requested plus all subseq uent cont iguous logi cal blocks

that are already in the cache. This data may be in multiple segments.

2. When a requested logical block is reached that is not in any cache segment, the drive fetches it and any

remaining requested logical block addresses from the disc and puts them in a segment of the cache. The drive transfers the remaining requested logical blocks from the cache to the host in accordance with the Mode Select Disconnect/Reconnect parameters, page 02h.

3. If the prefetch feature is enabled, refer to section 4.5.2 for operation from this point.

Case B—A Read command requests data, and the first logical block is not in any segment of the cache:

1. The drive fetches the requested logical blocks from the disc and transfers them into a segment, and then

from there to the host in accordance with the Mode Select Disconnect/Reconnect parameters, page 02h.

2. If the prefetch feature is enabled, refer to section 4.5.2 for operation from this point.

During a prefetch, the drive crosses a cylinder boundary to fetch data only if the Discontinuity (DISC) bit is set to 1 in bit 4 of byte 2 of the Mode Select parameters page 08h. Default is zero for bit 4.

Each cache segment is actually a self-contained circular buffer whose length is an integer number of logical blocks. The wrap-around capability of the individual segments greatly enhances the cache’s overall performance, allowing a wide range of user-selectable configurations. The drive supports operation of any integer number of segments from 1 to 32. Divide the 7,100 Kbytes in the buffer by the number of segments to get the segment size in bytes; then divi de b y the sector size to get the num ber of sector s per se gmen t, any p ar tial sectors remaining are not used. Default is 3 segments.

Savvio FC Product Manual, Rev. D

Note. The size of each segment is not reported by Mode Sense command page 08h, bytes 14 and 15.

The value 0XFFFF is always reported regardless of the actual size of the segment. Sending a size specification using the Mode Select command (bytes 14 and 15) does not set up a new segment size. If the STRICT bit in Mode page 00h (byte 2, bit 1) is set to one, the drive responds as it does for any attempt to change an unchangeable parameter.

4.5.1 Caching write data

Write caching is a write operation by the drive that makes use of a drive buffer storage area where the data to be written to the medium is stored while the drive performs the Write command.

If read caching is enabled (RCD=0), then data written to the medium is retained in the cache to be made available for future read cache hits. The same buffer space and segmentation is used as set up for read functions. The buffer segmentation scheme is set up or changed independently, having nothing to do with the state of RCD. When a write command is issued, if RCD=0, the cache is first checked to see if any logical blocks that are to be written are already stored in the cache from a previous read or write command. If there are, the respective cache segments are cleared. The new data is cached for subsequent Read commands.

If the number of write dat a logical blo cks excee d the size o f the segm ent b eing wr itten into, wh en th e en d of the segment is reached, the data is written i nto the b eginning of the same cache segment, overwriting the dat a that was written there at the beginning of the operation; however, the drive does not overwrite data that has not yet been written to the medium.

If write caching is enabled (WCE=1), then the drive may return Good status on a write command after the data has been transferred into the cache, but before the data has been written to the medium. If an error occurs while writing the data to the medium, and Good status has already been returned, a deferred error will be generated.

The Synchronize Ca che command may be used to force the drive to write all cached wri te dat a to the med ium. Upon completion of a Synchronize Cache command, all data received from previous write commands will have been written to the medium.

Table 17 shows the mode default settings for the drive.

4.5.2 Prefetch operation

If the Prefetch feature is enabled, data in contiguous logical blocks on the disc immediately beyond that which was requested by a Read command are retrieved and stored in the buffer for immediate transfer from the buffer to the host on subsequent Read commands that request those logical blocks (this is true even if cache operation is disabled). Though the prefetch operation uses the buffer as a cache, finding the requested data in the buffer is a prefetch hit, not a cache operation hit.

To enable Prefetch, use Mode Select page 08h, byte 12, bit 5 (Disable Read Ahead - DRA bit). DRA bit = 0 enables prefetch.

Since data that is prefetched replaces data already in some buffer segments, the host can limit the amount of prefetch data to optimize system performance. The Max Prefetch field (bytes 8 and 9) limits the amount of prefetch. The drive does not use the Prefetch Ceiling field (bytes 10 and 11).

During a prefetch operation, the drive crosses a cylinder boundary to fetch more data only if Mode parameters page 08h, byte 2, bit 4 is set to 1 (Discontinuity--DISC bit).

When prefetch (read look-ahead) is enabled (enabled by DRA = 0), it operates under the control of ARLA (Adaptive Read Look-Ahead). If the host uses software interleave, ARLA enables prefetch of contiguous blocks from the disc when it senses that a prefetch hit will likely occur, even if two consecutive read operations were not for physically contiguous blocks of data (e.g. “software interleave”). ARLA disables prefetch when it

Savvio FC Product Manual, Rev. D

decides that a prefetch hit will not likely occur. If the host is not using software interleave, and if two sequential read operations are not for contiguous blocks of data, ARLA disables prefetch, but as long as sequential read operations request contiguous blocks of data, ARLA keeps prefetch enabled.

4.5.3 Optimizing cache performance for desktop and server applications

Desktop and server applications require different drive caching operations for optimal performance. This means it is difficult to provide a single configuration that meets both of these needs. In a desktop environment, you want to configure the cache to respond quickly to repetitive accesses of multiple small segments of data without taking the time to “look ahead” to the next contiguous segments of data. In a server environment, you want to configure the cache to provide large volumes of sequential data in a non-repetitive manner. In this case, the ability of the cache to “look ahead” to the next contiguous segments of sequential data is a good thing.

The Performance Mode (PM) bit controls the way the drive switches the cache buffer into different modes of segmentation. In “server mode” (PM bit = 0), the drive can dynamically change the number of cache buffer segments as needed to optimize the performance, based on the command stream from the host. In “desktop mode” (PM bit = 1), the number of segments is maintained at the value defined in Mode Page 8, Byte 13, at all times. For additional information about the PM bit, refer to the Unit Attention Parameters page (00h) of the Mode Sense command (1Ah) in the Fibre C hanne l Interface Product Manual, part number 77767496.

5.1 Error rates

The error rates stated in this manual assume the following:

• The drive is operated in accordance with this manual using DC power as defined in paragraph 6.2, "DC

power requirements."

• Errors caused by host system failures are excluded from error rate computations.

• Assume random data.

• Default OEM error recovery settings are applied. This includes AWRE, ARRE, full read retries, full write

retries and full retry time.

Less than 1 error in 1012 bits transferred with minimum receive eye. Less than 1 error in 1014 bits transferred with typical receive eye. See Section 9.6.3, "Differential PECL input." on page 68

5.1.1 Recoverable Errors

Recoverable errors are those detected and corrected by the drive, and do not require user intervention. Recoverable Data errors will use correction, although ECC o n-the-fly is not considered fo r purposes o f recov-

ered error specifications. Recovered Data error rate is determined using read bits transferred for recoverable errors occurring during a

read, and using write bits transferred for recoverable errors occurring during a write.

5.1.2 Unrecoverable Errors

Unrecoverable Data Errors (Sense Key = 03h) are specified at less than 1 sector in error per 1015 bits transferred. Unrecoverable Data Errors resulting from the same cause are treated are 1 error for that block.

Savvio FC Product Manual, Rev. D

5.1.3 Seek errors

A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an initial seek error, the drive automatically performs an error recovery process. If the er ror recover y process fails, a seek positioning error (Error code = 15h or 02h) will be reported with a Hardware error (04h) in the Sense Key. Recoverable seek errors are specified at Less than 10 errors in 108 seeks. Unrecoverable seek errors (Sense Key = 04h) are classified as drive failures.

5.1.4 Interface errors

An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the device port connected to the receiver. The error may be detected as a running disparity error, illegal code, loss of word sync, or CRC error. The total error rate for a loop of devices is the sum of the individual device error rates.

5.2 Reli ab ilit y and servi ce

You can enhance the reliability of Savvio disc drives by ensuring that th e drive receive s adequ ate coo ling. S ection 6.0 provides temperature measurements and other information that may be used to enhance the service life of the drive. Section 8.1 provides recommended air-flow information.

5.2.1 Mean time between failures (MTBF)

The production disc drive achieves an MTBF of 1,400,000 hours when operated in an environment that ensures the case temperatures specified in Section 6.4.1 are not exceeded. Short-term excursions up to the specification limits of the operating environment will not affect MTBF performance. Operating the drive at case temperatures above these values will adversely affect the drive’s ability to meet specifications (see Section 6.4, "Environmental limits").

Estimated power-on operating hours means power-on hours per disc drive times the total number of disc drives in service. Each disc drive must have accumulated at least nine months of operation. Data is calculated on a rolling average base for a minimum period of six months.

MTBF is based on the following assumptions:

• 8,760 power-on hours per year

• 250 average on/off cycles per year

• Operating at nominal voltages

• System provides adequate cooling to ensure the case temperatures specified in Section 6.4.1 are not exceeded.

Drive failure means any stoppage or failure to meet defined specifications caused by drive malfunction. A S.M.A.R.T. predictive failure indicates that the drive is deteriorating to an imminent failure and is considered

a MTBF hit.

5.2.2 Preventive mainte nan ce

No routine scheduled preventive maintenance is required.

5.2.3 Hot plugging the drive

Inserting and removing the drive on the FC-AL will interrupt loop operation. The interruption occurs when the receiver of the next device in the loop must synchronize to a different input signal. FC error detection mechanisms, character sync, running disp a rity, word sync, and CRC are able to detect any error. Recovery is initiated based on the type of error.

Savvio FC Product Manual, Rev. D

The disc drive defaults to the FC-AL Monitoring state, Pass-through state, when it is powered-on by switching the power or hot plugged. The control line to an optional port bypass circuit (external to the drive), defaults to the Enable Bypass state. If the bypass circuit is present, the next device in the loop will continue to receive the output of the previous device to the newly inserted device. If the bypass circuit is not present, loop operation is temporarily disrupted until the next device starts receiving the output from the newly inserted device and regains synchronization to the new input.

The Pass-through state is disabled while the drive perfo rms self test of the FC interface. The control line for an external port bypass circuit remains in the Enable Bypass state while self test is running. If the bypass circuit is present, loop oper ation m ay con tinue. If the byp ass circ uit is not pres ent, loo p ope ration will be h alted while the self test of the FC interface runs.

When the self test completes successfully, the control line to the bypass circuit is disabled and the drive enters the FC-AL Initializing st a te. The receiver on the ne xt device i n the loo p must synch ronize t o outpu t of the newly inserted drive.

If the self-test fails, the control line to the bypass circuit remains in the Enable Bypass state. Note. It is the responsibility of the systems integrator to assure that no temperature, energy, voltage haz-

ard, or ESD potential hazard is presented during the hot connect/disconnect operation. Discharge the static electricity from the drive carrier prior to inserting it into the system.

Caution. The drive motor must come to a complete s t op pri or to ch anging the pl a ne of o pera tion. T his time is

required to insure data integrity.

5.2.4 S.M.A.R.T.

S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize conditions that indicate imminent drive failure and is designed to provide sufficient warning of a failure to allow you to back up the data before an actual failure occurs.

Note. The drive’ s f irmwar e moni tor s specific attr ibutes for degr adatio n ove r tim e b ut can ’ t predi ct in sta nt a-

neous drive failures.

Each monitored attribute has been selected to monitor a specific set of failure conditions in the operating performance of the drive and the thresholds are optimized to minimize “false” and “failed” predi ctions.

Controlling S.M.A.R.T.

The operating mode of S.M.A.R. T. is controlled by the DEXCPT and PERF bits on the Informa tional Exceptions Control mode page (1Ch). Use the DEXCPT bit to enable or disable the S.M.A.R.T. feature. Setting the DEXCPT bit disables all S.M.A.R.T. functions. W hen enab led, S .M. A.R.T. collect s on -li ne d at a as the d rive p erfor ms normal read and write operations. When the PERF bit is set, the drive is considered to be in “On-line Mode Only” and will not perform off-line functions.

You can measure off-line attributes and force the drive to save the data by using the Rezero Unit command. Forcing S.M.A.R.T. resets the timer so that the next scheduled interrupt is in two hours.

You can interrogate the drive thro ugh th e host t o dete rmine the time remaining before the next schedul ed me asurement and d at a logg i ng p rocess occur s . To accomplish this, issue a Log Sense comm and to log page 0x3E. This allows you to control when S.M.A.R.T. interruptions occur. Forcing S.M.A.R.T. with the RTZ command resets the timer.

Savvio FC Product Manual, Rev. D

Performance impact

S.M.A.R.T. attribute data is saved to the disc so that the events that caused a predictive failure can be recreated. The drive measures and saves parameters once every two hours subject to an idle period on the FC-AL bus. The process of measuring off-line attribute data and saving data to the disc is uninterruptable. The maximum on-line only processing delay is summarized below:

Maximum processing delay

S.M.A.R.T. delay times

On-line only delay DEXCPT = 0, PERF = 1

60 milliseconds

Fully-enabled delay DEXCP T = 0, PE R F = 0

370 milliseconds

Reporting control

Reporting is controlled by the MRIE bits in the Informational Exceptions Control mode page (1Ch). Subject to the reporting method, the firmware will issue to the host an 01-5D00 sense code. The error code is preserved through bus resets and power cycles.

Determining rate

S.M.A.R.T. monitors the rate at which error s occur and si gna ls a predi ctive fai lure if the rat e of degrad ed err ors increases to an unacceptabl e level. To determine rate, error events are logged and com pa red to the num ber of total operations for a given attribute. The interval defines the number of operations over which to measure the rate. The counter that keeps track of the current number of operations is referred to as the Interval Counter.

S.M.A.R.T. measures error rates. All errors for each monitored attribute are recorded. A counter keeps track of the number of errors for the current interval. This counter is referred to as the Failure Counter.

Error rate is the number of errors per oper ation. The algori thm tha t S .M.A.R .T. uses to re cord rate s of err or i s to set thresholds for the number of errors and their interval. If the number of errors exceeds the threshold before the interval expires, the error rate is considered to be unacceptable. If the number of errors does not exceed the threshold before the interval expires, the error rate is considered to be acceptable. In either case, the interval and failure counters are reset and the process starts over.

Predictive failures

S.M.A.R.T. signals predictive failures when the drive is performing unacceptably for a period of time. The firmware keeps a running count of the number of times the error rate for each attribute is unacceptable. To accomplish this, a counter is incremented each time the error rate is unacceptable and decremented (not to exceed zero) whenever the error rate is acceptable. If the counter continually increments such that it reaches the predictive threshold, a predictive failure is signaled. This counter is referred to as the Failure History Counter. There is a separate Failure History Counter for each attribute.

5.2.5 Thermal monitor

Savvio drives implement a temperature warning system which:

1. Signals the host if the temperature exceeds a value which would threaten the drive.

2. Signals the host if the temperature exceeds a user-specified value.

3. Saves a S.M.A.R.T. data frame on the drive which exceeds the threatening temperature value.

A temperature sensor monitors the drive temperature and issues a warning over the interface when the temperature exceeds a set threshold. The temperature is measured at power-up and then at ten-minute intervals after power-up.

Savvio FC Product Manual, Rev. D

The thermal monitor system generates a warning code of 01-0B01 when the temperature exceeds the specified limit in compliance with the SCSI standard. The drive temperature is reported in the FRU code field of mode sense dat a. You can use this infor matio n to deter mine if the warning is due to the tem per atur e excee ding the drive threatening temperature or the user-specified temperature.

This feature is controlled by the En able W a rni ng (EWasc) bit, and the reporting mechanism is controlled by the Method of Reporting Informational Exceptions field (MRIE) on the Informational Exceptions Control (IEC) mode page (1Ch).

The current algorithm implements two temperature trip points. The first trip point is set at 68°C which is the maximum temperature limit according to the drive specification. The second trip point is user-selectable using the Log Select command. The re feren ce tempe ratur e p aram eter in the tempera ture log page (see Table 1) can be used to set this trip point. The default value for this drive is 68°C, however, you can set it to any value in the range of 0 to 68°C. If you specify a temperature greater than 68°C in this field, the temperature is rounded down to 68°C. A sense code is sent to the host to indicate the rounding of the parameter field.

5.2.6 Drive Self Test (DST)

Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a failed unit. DST validates the functionality of the drive at a system level.

There are two test coverage options implemented in DST:

1. Extended test

2. Short text The most thorough option is the extended test that performs various tests on the drive and scans every logical

block address (LBA) of the drive. The short test is time-restricted and limited in length—it does not scan the entire media surface, but does some fundamental tests and scans portions of the media.

If DST encounters an error during either of these tests, it reports a fault condition. If the drive fails the test, remove it from service and return it to Seagate for service.

5.2.6.1 DST failure definition

The drive will present a “diagnostic failed” condition through the self-tests results value of the diagnostic log page if a functional failure is encountered during DST. The channel and servo parameters are not modified to test the drive more stringently, and the number of retries are not reduced. All retries and recovery processes are enabled during the test. If data is recoverable, no fa ilure condition will be reported regardless of the number of retries required to recover the data.

The following conditions are considered DST failure conditions:

• Seek error after retries are exhausted

• Track-follow error after retries are exhausted

• Read error after retries are exhausted

• Write error after retries are exhausted Recovered errors will not be reported as diagnostic failures.

Savvio FC Product Manual, Rev. D

5.2.6.2 Implementation

This section provides all of the information necessary to implement the DST function on this drive.

5.2.6.2.1 State of the drive prior to testing

The drive must be in a ready state before issuing the Send Diagnostic command. There are multiple reasons why a drive may not be ready, some of which are valid conditions, and not errors. For example, a drive may be in process of doing a form at, or anothe r D ST. It is the responsib ility o f the ho st applic atio n to det erm ine the “ not ready” cause.

While not technically part of DST, a Not Ready condition also qualifies the drive to be returned to Seagate as a failed drive.

A Drive Not Ready condition is reported by the drive under the following conditions:

• Motor will not spin

• Motor will not lock to speed

• Servo will not lock on track

• Drive cannot read configuration tables from the disc

In these conditions, the drive responds to a Test Unit Ready command with an 02/04/00 or 02/04/03 code.

5.2.6.2.2 Invoking DST

To invoke DST, submit the Send Diagnostic command with the appropriate Function Code (001b for the short test or 010b for the extended test) in bytes 1, bits 5, 6, and 7.

5.2.6.2.3 Short and extended tests

DST has two testing options:

1. short

2. extended

These testing options are described in the following two subsections. Each test consists of three segments: an electrical test segment, a servo test segment, and a read/verify scan

segment.

Short test (Function Code: 001b)

The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within 120 seconds. The short test does not scan the entire media surface, but does some fundamental tests and scans portions of the media. A complete rea d/ver ify scan is not per formed and onl y factu al failu res will report a fault condition. This option provides a quick confidence test of the drive.

Extended test (Function Code: 010b)

The objective of the extended test option is to empirically test critical drive components. For example, the seek tests and on-track operations test the positioning mechanism. The read operation tests the read head element and the media surface. The write element is tested through read/write/read operations. The integrity of the media is checked through a read/verify scan of the media. Motor functionality is tested by default as a part of these tests.

The anticipated length of the Extended test is reported through the Control Mode page.

Savvio FC Product Manual, Rev. D

5.2.6.2.4 Log page entries

When the drive begins DST, it creates a new entry in the Self-test Results Log page. The new entry is created by inserting a new self-te st parameter block a t the beginning of t he se lf-test results log p a ram eter section of the log page. Existing data will be moved to make room for the new parameter block. The drive reports 20 parameter blocks in the log p ag e. If th ere are more than 20 p ar amet er blocks, the least r ecent p a rame ter block will be deleted. The new parameter block will be initialized as follows:

1. The Function Code field is set to the same value as sent in the DST command

2. The Self-Test Results Value field is set to Fh

3. The drive will store the log page to non-volatile memory After a self-test is complete or has been aborted, the drive updates the Self-Test Results Value field in its Self-

Test Results Log page in non-volatile memory. The host may use Log Sense to read the results from up to the last 20 self-tests performed by the drive. The self-test results value is a 4-bit field that reports the results of the test. If the field is set to zero, the drive passed with no errors detected by the DST. If the field is not set to zero, the test failed for the reason reported in the field.

The drive will report the failure condition and LBA (if applicable) in the Self-test Results Log parameter. The Sense key, ASC, ASCQ, and FRU are used to report the failure condition.

5.2.6.2.5 Abort

There are several ways to abort a diagnostic. You can use a SCSI Bus Reset or a Bus Device Reset message to abort the diagnostic.

You can abort a DST executing in background mode by using the abort code in the DST Function Code field. This will cause a 01 (self-test aborted by the application client) code to appear in the self-test results values log. All other abort mechanisms will be reported as a 02 (self-test routine was interrupted by a reset condition).

5.2.7 Product warranty

Beginning on the date of shipment to the customer and continuing for the period specified in your purchase contract, Seagate warrants that each product (including components and subassemblies) that fails to function properly under no rmal use due to defect in m ater ials or workmanship or due to nonconforma nce to the applicable specifications will be repaired or replace d, at Seag ate’s option and at no charge to the customer , if r etur ned by customer at customer’s expense to Seagate’s designated facility in accordance with Seagate’s warranty procedure. Seagate will pay for transporting the repair or replacement item to the customer.

[2] For +12 V, a –10% tolerance is allowed during initial spindle start but must return to ±5% before reaching

10,000 RPM. The ±5% must be maintained after the drive signifies that its power-up sequence has been

completed and that the drive is able to accept selection by the host initiator. [3] See +12V current profile in Figure 2. [4] This condition occurs when the Motor Start option is enabled and the drive has not yet received a Start

Motor command. [5] See paragraph 6.2.1, "Conducted noise immunity." Specified voltage tolerance includes ripple, noise, and

transient response. [6] Operating condition is defined as random 8 block reads at:

258 I/Os per second (ST973401FC at 1Gbit operation)

259 I/Os per second (ST973401FC at 2Gbit operation)

258 I/Os per second (ST936701FC at 1Gbit operation)

258 I/Os per second (ST936701FC at 1Gbit operation) [7] During idle, the drive heads are relocated every 60 seconds to a random location within the band from

three-quarters to maximum track.

General DC power requirement notes.

1. Minimum current loading for each supply voltage is not less than 1.2% of the maximum operating current

shown.

2. The +5V and +12V supplies should employ separate ground returns.

3. Where power is provided to multiple drives from a common supply, careful consideration for individual

drive power requirements should be noted. Where multiple units are powered on simultaneously, the peak starting current must be available to each device.

4. Parameters, other than spindle start, are measured after a 10-minute warm up.

5. No terminator power.

6.4 Environmental limits

Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C). Maximum wet bulb temperature is 82°F (28°C).

6.4.1 Temperature

a. Operating

The maximum allowable continuous or sustained HDA case temperature for the rated MTBF is 122°F (50°C). The maximum allowable HDA case temperature is 60°C. Occasional excursions of HDA case temperatures above 122°F (50°C) or below 41°F (5°C) may occur without impact to specified MTBF. Continual or sustained operation at HDA case temperatures outside these limits may degrade MTBF.

Provided the HDA case temperatures limits are met, the drive meets all specifications over a 41°F to 131°F (5°C to 55°C) drive ambient temperature range with a maximum temperature gradient of 36°F (20°C) per hour . Air flow may be needed in the drive enclosu re to keep within this range (see Se ction 8.3). Operation at HDA case temperatur es out side thi s ra nge m ay adve rsely af fe ct the d rives ab ility t o mee t speci ficatio ns. To confirm that the required cooling for the electronics and HDA case is provided, place the drive in its final mechanical configuration, perform random write/read operations and measure the HDA case temperature after it has stabilized.

b. Non-operating

–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification assum es th at th e dr iv e is p ackaged in the shipping cont ain er desi gne d by Seagate for use w ith drive.

6.4.4 Shock and vibration

Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is installed in an enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur internally to t he e nclosure resulting in drive m oveme nt i n excess of t he st at ed l im its. If t hi s situat i on is app ar ent, it may be necessary to modify the enclosure to minimize drive movement.

The limits of shock and vibration defined within this document are specified with the drive mounted by any of the four methods shown in Figure 11, and in accordance with the restrictions of Section 8.3. Orientation of the side nearest the LED may be up or down.

6.4.4.1 Shock

a. Operating—normal

The drive, as in sta lled for normal operation, shall op erat e er ror fr ee wh ile sub je cted to in term i ttent shock not exceeding 15 Gs at a maximum duration of 11 msec (half sinewave). The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding 20 Gs at a maximum duration of 2 msec (half sinewave). Shock may be applied in the X, Y, or Z axis.

b. Operating—abnormal

Equipment, as installed for normal operation, does not incur physical damage while subjected to intermittent shock not exceeding 40 Gs at a maximum duration of 11 msec (half sinewave). Shock occurring at abnormal levels may promote degraded operational performance during the abnormal shock period. Specified operational performance will continue when normal operating shock levels resume. Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than two times per second.

c. Non-operating

The limits of non-operating shock shall apply to all conditions of handling and transportation. This includes both isolated drives and integrated drives.

6.4.4.2 Vibration

a. Operating—normal

The drive as installed for normal operation, shall comply with the complete specified performance while subjected to continuous vibration not exceeding

5-500 Hz @ 1.0 G (zero to peak) Vibration may be applied in the X, Y, or Z axis. Operating normal translational random flat profile 10 - 500 Hz 0.5 gRMS (grams Root Mean Squared)

b. Operating—abnormal

Equipment as installed for normal operation shall not incur physical damage while subjected to periodic vibration not exceeding:

15 minutes of duration at major resonant frequency

5-500 Hz @ 1.5 G (X, Y, or Z axis) Vibration occurring at these levels may degrade operational performance during the abnormal vibration

period. Specified operational performance will continue when normal operating vibration levels are resumed. This assumes system recovery routines are available.

Operating abnormal translational random flat profile 10 - 500 Hz 1.2 gRMS (grams Root Mean Squared)

c. Non-operating

The limits of non-operating vibration shall apply to all conditions of handling and transportation. This includes both isolated drives and integrated drives.

The drive shall not incur physical damage or degraded performance as a result of continuous vibration not exceeding

5-500 Hz @ 3.00 G (zero to peak) Vibration may be applied in the X, Y, or Z axis. Non-operating translational random flat profile 10 - 500 Hz 1.2 gRMS (grams Root Mean Squared)

6.4.5 Air cleanliness

The drive is designed to operate in a typical office environment with minimal environmental control.

6.4.6 Corrosive environment

Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing cannot duplicate every potential application environment.

Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals as electr onic dr i ve comp onen t reliab i lity can be affected by the inst allation environment. The sil- ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitr ate c ont ami na nt s. S ulfur is found to be the m ost dam aging . In ad diti on, e lectron i c comp onent s should never be exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an am bient rel at ive hum idity gr eate r th an 9 5%. Mat erial s used in cabin et fa bri cation , such as vulcanized rubber, that can outgas corrosive compounds sshould be minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free alternatives.

7.0 Defect and error management

The drive, as delivered, complies with this product manual. The read error rates and specified storage capacities are not dependent upon use of defect management routines by the host (initiator).

Defect and error management in the SCSI protocol involves the drive internal defect/error management and FC-AL system error considerations (errors in communications between the initiator and the drive). Tools for use in designing a defect/error management plan are briefly outl ined in this section. References to other sections are provided when necessary.

7.1 Drive internal defects/errors

During the initial drive format operation at the factory, media defects are identified, tagged as being unusable, and their locations recorded on the drive primary defects list (referred to as the “P’ list and also as the ETF defect list). At factory format time, these known defects are also reallocated, that is, reassigned to a new place on the medium and the location listed in the defects reallocation table. The “P” list is not altered after factory formatting. Locations of defects found and reallocated during error recovery procedures after drive shipment are listed in the “G” list (defects growth list). The “P” and “G” lists may be referenced by the initiator using the Read Defect Data command.

Details of the SCSI commands supported by the drive are described in the Fibre Channel Interface Manual. Also, more information on the drive Error Recovery philosophy is presented in the Fibre Channel Interface Manual.

7.2 Drive er ror recovery procedures

When an error occurs du ri ng dr ive ope ration, the drive, if program med t o do so, pe rfor ms er ror recove ry pro cedures to attempt to reco ver the dat a. T he err or r ecover y proce dure s used depend on the options pre viously set in the Error Recovery Parameters mode page. Error recovery and defect management may involve using several SCSI commands described in the Fibre Channel Interface Manual. The drive implements selectable error recovery time limits required in video applications.

The error r ecover y sche me suppo rted by t he d ri ve p rovide s a way to contr ol th e to tal error recovery time for the entire command in addition to controlling the recovery level for a single LBA. The total amount of time spent in error recovery for a command can be limited using the Recovery Time Limit bytes in the Error Recovery mode page. The total amount of time spent in error recovery for a single LBA can be limited using the Read Retry Count or Write Retry Count bytes in the Error Recovery mode page.

The drive firmware error recovery algorithms consists of 11 levels for read recoveries and five levels for write. Each level may consist of multiple steps, where a step is defined as a recovery function involving a single reread or re-write attempt. The maximum level used by the drive in LBA recovery is determined by the read and write retry counts.

Savvio FC Product Manual, Rev. D

Table 4 equates the read and write retry count with the maximum possible recovery time for read and write recovery of individual LBAs. The times given do not include time taken to perform reallocations. Reallocations are performed when the ARRE bit (for reads) or AWRE bit (for writes) is one, the RC bit is zero, and the recovery time limit for the command has not yet been met. Time needed to perform reallocation is not counted against the recovery time limit.

When the RC bit is one, reallocations are disabled even if the ARRE or AWRE bits are one. The drive will still perform data recovery actions within the limits defined by the Read Retry Count, Write Retry Count, and Recovery Time Limit parameters. However, the drive does not report any unrecovered errors.

LBA (cumulative, msec) Write retry count

Maximum recovery time per

LBA (cumulative, msec)

[1] Setting these retry counts to a value below the default setting could result in degradation of the unrecov-

ered error rate. For example, suppose the read/write recovery page has the RC bit = 0, the read retry count set to 4, and the recovery time limit set to 450. A 4-block read command can take up to 401 msec recovery time for each block and a maximum of 450 msec recovery for all four blocks. If either of these limits is reached and a block has not ye t been r ecover ed, th e command will end with Check Cond it ion st atus and an unrecoverable read error will be reported.

7.3 FC-AL system errors

Information on the reporting of operational errors or faults across the interface is given in the Fibre Channel Interface Manual. The FCP Response returns information to the host about numerous kinds of errors or faults.

The Receive Diagnostic Results reports the results of diagnostic operations performed by the drive. Status returned by the drive to the initiator is described in the Fibre Channel Interface Manual. Status reporting

plays a role in systems err or manag ement and its use in that resp ect is d escribed in se ctions whe re t he va rious commands are discussed.

Savvio FC Product Manual, Rev. D

8.0 Installation

Savvio disc drive installation is a plug-and-play process. There are no jumpers, switches, or terminators on the drive. Simply plug the drive into the host’s 40-pin Fibre Channel backpanel connector (FC-SCA)—no cables are required. See Section 9.5 for additional information about this connector.

Use the FC-AL interface to select drive ID and all option configurations for devices on the loop. If multiple devices are on the same FC-AL and physical addresses are used, set the device selection ID s (SEL

IDs) on the backp anel so that no two devices have th e sam e select ion ID. T his is ca lled the har d assi gn ed arbi trated loop physical ad dress ( AL_PA). There are 125 AL_PAs available (see Table 25). If you set the AL_PA on the backpanel to any value other than 0, the device plugged into the backpanel’s SCA connector inherits this AL_PA. In the event you don’t successfully assign unique hard addresses (and therefore have duplicate selection IDs assigned to two or more devices), the FC-AL generates a message indicating this condition. If you set the AL_PA on the backpanel to a value of 0, the system issues a unique soft-assigned physical address automatically.

Loop initialization is the process used to verify or obtain an address. The loop initialization process is performed when pow er is applied to the drive, whe n a device is added or removed from the F ibre Cha nnel loop , or when a device times out attempting to win arbitration.

• Set all option selections in the connector prior to applying power to the drive. If you change options after applying power to the drive, recycle the drive power to activate the new settings.

• It is not necessary to low-level format this drive. The drive is shipped from the factory low-level formatted in 512-byte logical blocks. You need to refo rma t the drive only if you want to se lect a dif fer ent lo gical blo ck size.

8.1 Drive or ientat ion

The drive may be mounted in any orientation. All drive performance characterizations, however, have been done with the drive in horizontal (discs level) and vertical (drive on its side) orientations, which are the two preferred mounting orientations.

8.2 Cooling

The host enclosure must dissipate heat from the drive. You should confirm that the host enclosure is designed to ensure that the dr ive ope rate s w ithin the tempe ratu re m easur emen t guide lin es descr ibed in S ectio n 6.4. 1. In some cases, forced airflow may be required to keep temperatures at or below the temperatures specified in Section 6.4.1.

If forced air is necessary, possible air-flow patterns are shown in Figure 13. The air-flow patterns are created by fans either forcing or drawing air as shown in the illustrations. Conduction, convection, or other forced airflow patterns are acceptable as long as the temperature measurement guidelines of Section 6.4.1 are met.

8.3 Drive mounting

Use M3 x .5 metric screws to mount the drive using either side, bottom, or end mounting holes. Select a screw length that results in a minimum thread engagement of 0.12 inches when using the side-mounting holes or a minimum thread engagement of 0.10 inches when using the bottom or end mounting holes. Use a maximum torque of 4.5 +/- .45 in lbs. If the screws are torques above the specified values, threads could be stripped.

Note. Before mounting the dr ive in a ny kind of adapter frame, ver i fy tha t the drive can meet the shock and

vibration specifications while mounted in such an adapter frame.

8.4 Grounding

Signal ground (PCBA) and HDA ground are connected together in the drive and cannot be separated by the user. The equipment in which the drive is mounted is connected directly to the HDA and PCBA with no electrically isolating shock mounts. If it is desired for the system chassis to not be connected to the HDA/PCBA ground, the systems integrator or user must provide a nonconductive (electrically isolating) method of mounting the drive in the host equipment.

Increased radiated emissions may result if you do not provide the maximum surface area ground connection between system ground and drive ground. This is the system designer’s and integrator’s responsibility.

9.2 Dual port support

Savvio drives have two independent FC-AL ports. These ports may be connected on independent loops or on the same loop. Port A and Port B may be connected in any order or combination.

• If both ports ar e conn ected on i nde pend ent loo ps and h ard a ddre ssi ng is use d, the driv e in terfa ce add ress i s selected through the interface connector, both ports will seek the same loop address. If no conflict, both ports will have the same loop address.

• If both ports are connected in the same loop and hard addressing is used, at least one port will attempt taking a soft address to prevent an address conflict.

Subject to buffer availability, the Savvio drives support:

• Concurrent port transfers—The drive supports receiving transfers on both ports at the same time when the ports are on independent loops.

• Full duplex—The drive supports sending FCP_Data, FCP_RSP, FCP_XFR_RDY and ELS transfers while receiving frames on both ports.

9.3.2 Mode Sense data

The Mode Sense command provides a way for the drive to report its operating parameters to the initiator. The drive maintains four sets of mode parameters:

1. Default values

Default values are hard-coded in the drive firmware stored in flash E-PROM (nonvolatile memory) on the drive’s PCB. These default values can be changed only by downloading a complete set of new firmware into the flash E-PROM. An initiator can request and receive from the drive a list of default values and use those in a Mode Select command to set up new current and saved values, where the values are changeable.

2. Saved values

Saved values are stored on the drive’s media using a Mode Select command. Only parameter values that are allowed to be chang ed c an b e cha nged by th i s me thod. Pa ram eters in th e save d va lues l ist that are not changeable by the Mode Select command get their values from default values storage.

When power is applied to the drive, it takes saved values from the media and stores them as current values in volatile memory. It is not possible to change the current values (or the saved values) with a Mode Select command before the drive achieves operating speed and is “ready.” An attempt to do so results in a “Check Condition” status.

On drives requiring unique saved values, the required unique saved values are stored into the saved values storage location on the media prior to shipping the drive. Some drives may have unique firmware with unique default values also.

Savvio FC Product Manual, Rev. D

On standard OEM drives, the saved values are taken from the default values list and store d into the saved values storage location on the media prior to shipping.

3. Current values Current values are volatile values bei ng used by the driv e to contro l its operation. A Mod e S elect comm and

can be used to change the values identified as changeable values. Originally, current values are installed from saved or default values after a power on reset, hard reset, or Bus Device Reset message.

4. Changeable values Changeable values for m a bit mask, stored in no nvolatil e me mor y, that dictates which of the current values

and saved values can be changed by a Mode Select command. A one (1) indicates the value can be changed. A zero (0) indicates the value is not changeable. For example, in Table 17, refer to Mode page 81, in the row entitled “CHG.” These are hex numbers representing the changeable values for Mode page

81. Note in colu mns 5 and 6 ( bytes 0 4 an d 05) , th ere is 00h w hich ind ic ates th at in bytes 0 4 an d 05 none of the bits are changeable. Note also that bytes 06, 07, 09, 10, and 11 are not changeable, because those fields are all zeros. In byte 02 , hex val u e FF equates to the binary pattern 111 11111. If there is a zero in any bit position in the field, it means that bit is not changeable. Since all of the bits in byte 02 are ones, all of these bits are changeable.

The changeable values list can only be changed by downloading new firmware into the flash E-PROM.

Note. Because there are often several different versions of dr ive contr ol fi rm ware in the total population of

drives in the field , the Mode Sense values given in the followi ng ta bles m ay not exactly m atch t hose of some drives.

The following table s list the values of the dat a bytes returned by the drive in response to the Mode Sense command pages for SCSI implementation (see the Fibre Channel Interface Manual ).

Definitions: DEF = Default value. Standard OEM drives are shipped configured this way. CHG = Changeable bits; indicates if default value is changeable.

9.5.1 Physical character istic s

This section defines physical interface connector.

9.5.1.1 Physical descriptio n

FIbre Channel drives may be connected in a loop together or with other compatible FC-AL devices. A maximum of 127 devices may have addresses; however, one of the addresses is reserved for a fabric port switch device. This means 126 addresses are available for FC-AL devices. More FC-AL compatible devices may physically reside on the loop, but they will not be functional because they would not be able to obtain valid addresses.

Port bypass circuits (PBCs) allow devices to be inserted into unpopulated locations or removed from the loop with loop operation recovery after a brief interruption. These PBCs are located external to the FC-AL device. Figure 15 shows the relationship between the PBC and FC-AL device.

9.5.5 FC-AL transmitters and receivers

Receiver

Savvio drives use 100 ohm termination which makes it compatible with backplanes designed for 1, 2, or 4 Gbit Fibre Channel transfer rates. Previous generations of Seagate FC products used 150 ohm impedance for operation in host systems designed to operate in 1 or 2 Gbit transfer rate environments.

9.5.6 Power

Power is supplied through the FC-SCA with support for +5 volts and +12 volts. All of the voltage pins in the drive connector are the same length.

Four 12 volt pins provide +12 volt power to the drive. The current return for the +12 volt power supply is through the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins. The maximum current typically occurs while the drive motor is starting.

Three 5 volt pins pro vide l ogic powe r to the d riv e. Th e curr ent re turn for the +5 vol t p ower sup pl y is th roug h the common ground pins. Distribute supply and return current as evenly as possible among the voltage and ground pins.

The mating connector pins use shorter contacts to achieve power surge reductions and to aid in “hot plugging” the drives. There are longer voltage contacts in the connector to enable the drive filter capacitors to charge. Current to the drive through the long charge pins is limited by the system in which the drive operates. Three of the +12 volt pins ar e shor ter to all ow ca pa citi ve pr e-cha rging throu gh th e longe r + 12 v olt charge pi n . Two of the +5 volt pins are shorter to allow capacitive precharging through the longer +5 volt charge pin.

9.5.7 Fault LED Out

The Fault LED Out signal is driven by the drive when:

• the drive detects failure of both ports

• the drive detects an internal failure

• the drive receives the appropriate fault LED command from the host The Fault LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the proper

+5 volt supply through an appropriate current-limiting resistor. The LED and the current-limiting resistor are external to the drive.

Savvio FC Product Manual, Rev. D

9.5.8 Active LED Out

The Active LED Out signal is driven by the drive as indicated in Table 23.

T ab le 23: Active LED Out conditions

The Active LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the proper +5 volt supply through an appropriate current limiting resistor. The LED and the current limiting resistor are external to the drive.

9.5.9 Enable port bypass signals

The – Enable Bypass P ort A (– EN BYP P ort A) an d – En able By p ass Port B (– EN BYP Por t B) si gnals con trol the port bypass circuits (PBC) located external to the disc drive. The PBC allows a loop to remain functional in the event of a drive failure or removal. When these signals are active, low, the PBC bypasses the drive on the associated port. When an Enable Bypass signal is active, the corresponding Port Bypass LED signal in connector J1 is driven low by the disc drive. A pull down resistor, 1K, located with the PBC should be used to insure the bypass is enabled if the disc drive is not installed.

The Enable Bypass signal is active under failing conditions within the drive, on detection of the Loop Port Bypass primitive se quen ce, or on r emo val of t he dr ive. In the b yp ass state the drive con tinues t o re ceiv e on the inbound fibre. Enable Bypass may be deactivated by detection of a Loop Port Enable primitive sequence if the drive has completed self-test and a hardware failure is not present.

Failure modes detected by the disc drive that will enable bypass include:

• Transmitter/receiver wrap test failure

• Loss of receive clock

• Loss of transmission clock

• Drive interface hardware error

9.5.10 Motor start controls

The drive’s motor is started according to the Start_1 and Start_2 signals described in Table 24. The state of these signals can be wired into the backplane socket or driven by logic on the backplane.

Case Start_2 Sta rt_1 Motor spin function

1 Low Low Motor spins up at DC power on. 2 High Low Motor spins up only when SCSI Start command is received. 3 Low High Motor spins up after a delay of 12 seconds times the modulo 8 value of

the numeric SEL ID of the drive from DC power on.

4 High High The drive will not spin up.

9.5.11 SEL_6 through SEL_0 ID lines

The SEL_6 through SEL_0 ID lines determine drive address, and, optionally, for an Enclosure Services Interface. When the Parallel ESI line is hig h, the en closure backp anel must provide address info rma tion on th e SEL line. Refer to table 25 for a mapping of SEL to FC-AL physical addresses (AL_PA). You can think of the SEL lines as the equivalent of a backpanel logic plug. The drives does not provide pull up resistors on these lines. The backpanel is required to provide high and low inputs to the SEL_ID lines per the specifications in table 27 on page 67.

Note. Table 25 gives AL_PA values for each SEL value. The first entry in the table is SEL_ID 00. The last

entry is SEL_ID 7D. SEL_ID 7E is AL_PA 00 which is not valid for an NL_Port, so is not included in the table. Also, SEL_ID 7Fh does map to a valid AL_PA; however, this value signals the drive that physical addresses are not being assigned using the SEL lines and that a “soft” address will be determined by FC-AL loop initialization.

When the Parallel ESI line is low, the enclosure backpanel logic switches to ESI mode if supported. There are two modes of ESI, seven bits of enclosure status and a bidirectional mode. ESI support and the mode are determined by the drive using a discovery process. Refer to the Fibre Channel Interface Manual for a descrip- tion of ESI operation.

9.5.1 1.1 Parallel Enclosure Serv ices Inte rface (ESI )

The parallel ESI line is an output from the drive. This line provides the enclosure with an indication of the present function of the SEL lines. A high level, the default state, indicates the drive requires address information on the SEL lines. A low level indicates the drive is attempting an ESI transfer. The enclosure may not support ESI on any or all drive locations. It may only suppo rt the address functi on . Support of ESI is discovered by the drive. Refer to the Fibre Channel Interface Manual for a description of ESI operations.

9.5.12 Device control codes

The drive inputs a Device Control Code on the DEV_CTRL_CODE lines at power up to determine the link rate on the Fibre Channel ports. Both ports run at the same rate. If the backpanel does not connect to these lines, the drive has 10K ohm pull up resistors that default the device control code to 7 (1.0625 GHz). Table lists the supported codes.
