Reconnection
Relinkage of an initiator to a disconnected target
when a target operation on a SCSI bus is needed
Rotational delay
Time for one rotation of a disk. Average
rotational delay is the time for half a rotation of a
disk. Average rotational delay is the average
time from positioning a head on a track to
reaching a sector.
SCSI device
A generic name for input/output devices,
input/output controllers, host adapters, and other
devices connected to a SCSI bus
SCSI ID
A physical device address which identifies a
SCSI device on a SCSI bus. A SCSI ID is
specific to each SCSI device. SCSI IDs #0 to #7
can be assigned. A SCSI ID must correspond to
the bit number of a SCSI bus.
Seek time
Time required to move a head from the current
track to a requested track. The seek time does
not include the average rotational delay.
Sense code
A 1-byte code in sense data. A sense code
identifies the type of error detected.
Sense data
Information generated by a target if an error is
detected at command end. Sense data is used to
post detailed information about the error.
Sense key
A 4-bit code in sense data. A sense key classifies
the type of error detected.
Small computer system interface (SCSI)
An input-output interface standardized by the
American National Standards Institute (ANSI)
[Standard number: ANSI X3.131-1986]
Status
One-byte information posted from a target to an
initiator when execution of each command ends.
This information indicates the end of the
command state.
Target (TARG)
A SCSI device that executes the input/output
operation that was initiated by an initiator (INIT)
Voice coil motor (VCM)
A motor excited by one or more magnets. In the
this disk drive, VCM is used to position the
heads correctly at high speed.
