Operator Intervention Message Management for Tape Drive Displays

      This invention describes an improved system for managing
operator intervention messages on a magnetic tape device with an
all-points-addressable-display, an automatic cartridge loader, and a
separate cartridge loader port.

      In the proposed system, Intervention Messages are distinguished
and managed independently from other types of messages such as device
activity and status messages.  Intervention Messages appear in a
single-line of text in an "Intervention Message Window".  They are
presented in a larger font than other text information (e.g., control
menu choices, device status information, etc.)  presented in other
windows on the display panel.

      In the improved system of intervention messages, the following
categories of operator intervention messages are displayed:

o   FID 1:  FID stands for Field Replacable Unit Identifier, and FID
    1 messages are issued from the device when a hardware failure
    occurs that prevents subsequent operation of the device.  FID 1
    messages inform operators of the need for service level
    intervention.  A numeric code in the FID 1 message identifies the
    component to be replaced by service personnel.  FID 1 messages
    have priority over all other messages and persist until the error
    condition is resolved.

o   CHECK:  Check messages are issued by the device when an error
    condition occurs that customer personnel may be able to resolve.
    Check messages have priority over Routine Intervention Messages,
    FID 2 messages, and FID 3 messages.

o   Routine Intervention Messages:  Routine Intervention Messages may
    be issued from a host computer that is attached to the device or
    from the device itself.  Routine Messages direct operators to
    perform routine actions (e.g. mount tape volumes, demount tape
    volumes, clean the device, etc.).  There are subcategories of
    Routine messages and rules are defined that regulate how these
    messages are displayed (see below).  Note that these messages are
    filtered in such a way that they are displayed only when human
    intervention is required.

    Routine messages have a lower priority than FID 1 or Check
    messages.  Routine messages have a higher priority than FID 2 and
    FID 3 messages.

o   FID2:  FID 2 messages originate in the device and indicate a
    device error that permits the device to continue functioning in a
    degraded state.  FID 2 messages have a lower priority than FID 1,
    Check, and Routine messages.  FID 2 messages have a higher
    priority than FID 3 messages.

o   FID 3: FID 3 messages indicate a device error in service
    circuitry that otherwise has no effect on the operation of the
    device.  FID 3 messages have the lowest priority of all the
    message classes.
