Operating the Tape Library
3.1
Operator Control Panel (OCP)
There are 2 basic modes that the OCP operates in. First is the User Interaction mode. This mode is employed
when a user is pushing buttons on the OCP. The second mode is the System Driven mode. This is the normal
mode of operation. In this mode, the OCP displays status associated with the actions that were caused from
commands issued via the Drive's serial interface. Actions like Loading, Rewinding or Moving tape will be
displayed. When an OCP button is pressed and released, the OCP automatically transitions to User Interaction
mode. User Interaction mode will continue until 3 minutes after a user stops pushing buttons, or the
requested robotic action stops -whichever is longer. At this time the OCP will return to System driven mode.
In case of activated User security feature the User Interaction Mode is restricted to the Information and Login
menu item, until a login with correct PIN is done.
3.1.1
OCP Philosophy
OCP operation must obey some basic rules. These rules of operation constitute a 'philosophy'.
•
Any operational conflict between commands received over RMU and those entered via the front panel will
be avoided with a reservation mechanism on a 'first-come, first-served' basis. Any reservation by OCP is
canceled by an OCP logout or the timeout, which cancels the User Interaction Mode.
•
Library firmware will not allow a user to select an impossible request. Those situations will include, but are
not limited to:
-
Moving a cartridge from any source to a full slot
-
Moving a cartridge from an empty slot
-
Loading a cartridge from any source to a full drive
-
Unloading a cartridge from an empty drive
•
Any error detected by the library or drive controller and not recoverable through predetermined firmware
algorithms will be considered as fatal. An error code will be displayed on the LCD and the error LED will
become illuminated. The error code will remain on the OCP until a push button is pressed, which will cause
the OCP to return to the Home Screen.
•
Text status messages are provided with numeric error codes used for unrecoverable, fatal errors.
