5 Operating the tape library
5.1 Operating Modes
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 Op-Panel. The second mode is the System Driven
mode. This is the normal mode of operation. In this mode, the Op-Panel 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 Op-Panel button is pressed and
released, the Op-Panel 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 Op-Panel 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.
5.2 OCP Philosophy
OCP operation must obey 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 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.

Numeric error codes are only used for unrecoverable, fatal errors, otherwise text status
messages are provided.
