Operating the tape Library
7.1
Operator Control Panel (OCP)
There are 2 basic modes that Operator Control Panel (OCP). 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 Library 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.
7.2
OCP Philosophy
The OCP operation obeys some basic rules. These rules of operation constitute a ‘philosophy’.
Any operational conflict between commands received over SCSI or RMU and those
entered via the fro
nt 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.
