Q24/Q48 Tape Library

3 Operating Procedures

This section provides information about operating and configuring the Q24/Q48 Tape Library.
3.1

Operator control panel (OCP)

3.1.1

Operating Modes

1. User interaction mode: This mode is employed when a user is pushing buttons on the operating
The OCP operates in two basic modes:
panel.
2. System driven mode: This is the normal mode of operation. In this mode, the operating panel
displays status associated with the actions that were caused from commands issued from the host
software application. Actions like loading, rewinding or moving tape cartridges will be displayed.
Whenever an operating button is pressed and released, the operating panel automatically transitions
to user interaction mode. The user interaction mode will be active until 3 minutes after the user stops
pushing buttons, or the requested media changer activity stops – whichever is longer. At this time, the
operating panel will return to the system driven mode.
In the event that the administrator-programed user security feature is in use, the user interaction
mode is restricted to the information and login menu screens, until a login with correct PIN is entered.
3.1.2

OCP Rules

1. Any operational conflict between commands received from the host interface or RMU and those
OCP commands obey the following basic rules:
entered via the front panel will be avoided with a reservation mechanism on a 'first-come, first-
served' basis.
Any reservation by OCP is cancelled by an OCP logout or timeout, which cancels the User
Interaction Mode.
2. The library firmware will not allow a user to select an impossible request. Those situations include,
but are not limited to:
Moving a tape cartridge from any source to a full magazine slot
Moving a tape cartridge from an empty magazine slot
•
Loading a tape cartridge from any source to a full tape drive
•
Unloading a tape cartridge from an empty tape drive
•
•
3. 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 button is
pressed, which will cause the OCP to return to the home screen.
4. Numeric error codes are only used for unrecoverable, fatal errors (see Section 4.7.5, Main error
codes), otherwise text status messages are provided.
