Work division Precaution Page
Assembly/installation Damage to drive
A hole or screw portion as shown in Figure 4.8 is used for adjusting air
pressure balance between inside and outside the DE. Do not fill with a
seal or label.
Seals on the DE prevent the DE inside from the dust. Do not damage or
peel off labels.
4-8
Damage
1. When dismounting the drive which is mounted on the system while
power is supplied to it.
• The drive to be dismounted must be separated from the loop.
Dismounting the drive which is not separated from the loop may
cause an unexpected error.
• If the drive is not separated from the loop, issue an LPB to the
drive from the initiator in a primitive sequence of the order set.
• It is recommended to stop the spindle motor prior to this loop
separation operation. The spindle motor can be stopped by a
START/STOP command. It takes about 30 seconds for the
spindle motor to stop completely.
• Then, dismount the drive using the drive mounting/dismounting
mechanism, etc. of the system. If the drive is dismounted while
the spindle motor is running, special care is required to avoid
excessive vibration or shock to the drive. It is recommended to
stop the operation once the SCA connector breaks off contact
and wait until the spindle motor stops (about 30 seconds) before
dismount the drive.
• When storing or transporting the drive, put it in an antistatic
bag. (Shown in Section 5.1).
2. When dismounting the drive which is mounted on the system while
power is not supplied to it
• Do not move the drive until the drive stops completely (about 30
seconds if the spindle motor was stopped by a START/STOP
UNIT command, and about 30 seconds after powering-off when
the power was simply turned off).
• Then, dismount the drive using the drive mounting/dismounting
mechanism, etc. of the system.
• When storing or transporting the drive, put it in an antistatic
bag. (Shown in Section 5.1).

When the SEND DIAGNOSTIC command terminates with the CHECK
CONDITION status, the INIT must collect the error information using
the REQUEST SENSE command. The RECEIVE DIAGNOSTIC
RESULTS command cannot read out the error information detected in
the self-diagnostics.

CHAPTER 1 GENERAL DESCRIPTION
1.1 Standard Features
1.2 Hardware Structure
1.3 System Configuration
This chapter describes the feature and configuration of the intelligent disk drives (IDD).
MAF3364FC and MAG series intelligent disk drives (IDDs) are high performance large capacity 3.5-inch
fixed disk drives with an embedded fibre-channel controller.
The interface between the MAF3364FC/MAG series intelligent disk drives and host system conforms to
the fibre channel PLDA standard [NCITS TR-19 FIBRE CHANNEL PRIVATE LOOP SCSI DIRECT
ATTACH (FC-PLDA] which covers from the fibre channel physical layer to SCSI command protocol.
A combination of the high transfer speed and long-distance transfer of the fibre channel and high function
command set of the MAF3364FC and MAG series intelligent disk drives will facilitate construction of a
high performance and highly reliable disk subsystem with large storage capacity.
With respect to data formatting, it is possible to change it to a format different from the one at the time of
shipment by performing reinitialization on the installed system.

C141-E078-02EN1 - 2
1.1 Standard Features
(1) Compactness
The IDD has the FC-AL controller which supports the Arbitrated Loop (FC-AL) of the fibre
channel modes defined by the ANSI standard, embedded in the 3.5-inch fixed disk drive form
factor.
(2) FC-AL standard
The IDD provides not only FC-AL basic functions but also the following features:
•Arbitration
•Data frame CRC function
•Command set which meets the logical specification of the SCSI CCS (Common Command
Set for Direct Access Device) requirements (Rev. 4.B)
The SCSI commands can manipulate data through logical block addressing regardless of the
physical characteristics of the disk drive. This allows software to accommodate future expansion
of system functions.
(3) Dual port support
In order to support dual ports, the IDD is equipped with two pairs of fibre channel
driver/receiver.
(4) High speed data transfer
The data transfer rate on the fibre channel loop is 106.25 MB/s maximum. In addition, the large
capacity data buffer of the IDD allows the user to make full use of the high speed data transfer
capability of the fibre channel loop.
(5) High speed spindle motor
The IDD increases the number of revolutions of the spindle motor from conventional 7,200 rpm
to 10,025 rpm. Increasing the number of revolutions of the spindle motor will make it possible to
improve the data transfer rate and reduce the rotation wait time.
(6) Continuous block processing
The addressing method of data blocks is logical block address. The initiator can access data by
specifying block number in a logically continuous data space without concerning the physical
structure of the track or cylinder boundaries.
The continuous processing up to [64K-1] blocks in a command can be achieved, and IDD can
perform continuous read/write operation when processing data blocks on several tracks or
cylinder.

C141-E078-02EN 1 - 3
(7) 4MB programmable multi-segment data buffer
Data is transferred between fibre-channel loop and disk media through the embedded 4MB data
buffer in the IDD. This buffer can be divided into maximum 32 areas. This feature provides the
suitable usage environment for users.
Since the initiator can control the disconnect/reconnect timing on the fibre-channel loop by
specifying the condition of stored data to the data buffer or empty condition of the data buffer, the
initiator can perform the effective input/output operations with utilizing high data transfer
capability of the fibre-channel regardless of actual data transfer rate of the disk drive.
(8) Read-ahead cache feature
After executing the READ command, the IDD reads automatically and stores (prefetches) the
subsequent data blocks into the data buffer (Read-ahead caching).
The high speed sequential data access can be achieved by transferring the data from the data
buffer without reaccessing the disk in case the subsequent command requests the prefetched data
blocks.
(9) Command queuing feature
The IDD can queue maximum 63 commands, and optimizes the issuing order of queued
commands by the reordering function. This feature realizes the high speed processing.
(10) Reserve and release functions
The IDD can be accessed exclusively in the multi-host or multi-initiator environment by using
the reserve and release functions.
(11) Enclosure service function
The IDD supports an enclosure service interface (ESI) compliant with the SFF-8067. This
interface provides the function of setting/readin enclosure service information using the SCSI-3
enclosure service command set (SES).
(12) Error recovery
The IDD can try to recover from errors in fibre-channel loop or the disk drive using its powerful
retry processing. If a recoverable data check occurs, error-free data can be transferred to the
initiator after being corrected in the data buffer. The initiator software is released from the
complicated error recover processing by these error recoveryfunctions of the IDD.
(13) Automatic alternate block reassignment
If a defective data block is detected during read, the IDD can automatically reassign its alternate
data block.
