Operating the tape loader
7.1
Operator Control Panel (OCP)
7.1.1 Operating modes
There are 2 basic modes for 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 loader 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 for 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 entered.
7.1.2 OCP Philosophy
During the following discussion of the OCP operation, several functional nuances may be
clarified by defining several rules the OCP must abide by. 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 avo
ided with a reservation mechanism on a ‘first-
come, first-
served’ basis. Any reservation by the 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
Unloading a cartridge from an empty slot
Moving a cartridge from any source to a full drive
Unloading a cartridge from an empty drive
Any error detected by the library controller or the drive and not recoverable through
predetermined firmware algorithms, will be considered as fatal. An error code will
be displayed on the OCP and the error LED will become illuminated. The error code
will remain on the OCP until a push button is pressed, the OCP will return to the
Home Screen.
Numeric error codes are only used for unrecoverable, fatal errors, otherwise text
status messages are provided.
