•
While the door is opened, the library responds to the Inquiry,
Request Sense, Log Sense, and Mode Sense commands. Check
Condition is set for all other commands issued during this time
and the “Door is Opened” condition (SK=2 ASC=80 ASCQ=00) is
set in the sense data.
System Stopped Sequence
The STOP switch allows the operator to stop all power to the
actuators. The following actions occur when the system is stopped:
•
The control panel indicates that the system is stopped.
•
The library generates a “System Stop Button Was Pressed” event
(SK=6 ASC=80 ASCQ=07).
•
The system halts all library motion. Any motion command
currently in progress is aborted and Check Condition status is
returned to host. The “System is Stopped” condition (SK=2
ASC=80 ASCQ=07) is set in the sense data.
•
While the system is stopped, the library responds to the Inquiry,
Request Sense, Log Sense, and Mode Sense commands. Check
Condition status is set for all other commands issued during this
time, and the “System is Stopped” condition (SK=2 ASC=80
ASCQ=07) is set in the sense data.
On-line Initialization Sequence
The
STANDBY
switch allows the library to be placed on-line. The
on-line initialization sequence occurs only after the door is shut, the
system is not stopped and the library does not have the
STANDBY
button pressed. The following actions occur during the on-line
initialization sequence:
•
The control panel indicates that the library is performing the
on-line initialization sequence.
•
The local controller for the library performs a test to check the
operation of the library unit mechanisms.
•
The mechanisms are then homed.
•
During this time, the library responds to the Inquiry, Request
Sense, Log Sense, and Mode Sense commands. Check Condition
status is set for all other commands, and the “Logical Unit in
Process of Becoming Ready” condition (SK=2 ASC=04 ASCQ=01)
is set in the sense data.
