Description
NO SENSE. Indicates that there is no specific sense key
information to be reported for the designated logical unit. This
would be the case for a successful command or a command that
received CHECK CONDITION or COMMAND
TERMINATED status because one of the filemark, EOM, or
ILI bits is set to one.
NOT READY. Indicates that the logical unit addressed cannot
be accessed. Operator intervention may be required to correct
this condition.
MEDIUM ERROR. Indicates that the command terminated
with a non-recovered error condition that was probably caused
by a flaw in the medium or an error in the recorded data. This
sense key may also be returned if the target is unable to
distinguish between a flaw in the medium and a specific
hardware failure (sense key 4h)
HARDWARE ERROR. Indicates that the target detected a non-
recoverable hardware failure (for example, controller failure,
device failure parity error, etc.) while performing the command
or during a self test.
ILLEGAL REQUEST. Indicates that there was an illegal
parameter in the command descriptor block or in the additional
parameters supplied as data for some commands (FORMAT
UNIT, SEARCH DATA, etc.). If the target detects an invalid
parameter in the command descriptor block then it shall
terminate the command without altering the medium. If the
target detects an invalid parameter in the additional parameters
supplied as data, then the target may have already altered the
medium. This sense key may also indicate that an invalid
INDENTIFY message was received
UNIT ATTENTION. Indicates that the removable medium
may have been changed or the target has been reset. See ANSI
SCSI-2 7.9 for more detailed information about the unit
attention condition.
ABORTED COMMAND. Indicates that the target aborted the
command. The initiator may be able to recover by trying the
command again.
