state and notifies all attached hosts of the state change. The System Summary
window is updated to indicate intervention is required.

The notification that the library is in the Intervention Required state will generate
the following console message for libraries managed under DFSMS/MVS
System Managed Tape environment: CBR3762E, Library

library-name

intervention required

The message will stay on the console as long as the library is in the intervention
required state.

3. If “Send Interventions to Host Consoles” is enabled on the Operator Intervention

screen (under the Commands Menu), a broadcast message of the operator
intervention text will be sent to all attached hosts.

For Libraries managed under DFSMS/MVS system managed tape environment,
this will result in the following message being displayed at the host console:
CBR3750I Message from Library

library-name: message. Intervention text will

be truncated at 70 characters. See Table 7 on page 216 for complete text string
based on intervention number.

For other operating systems, consult the associated supporting software
publications to determine operator notification methods.

To determine the cause of an intervention required condition and the steps required
for its resolution, the operator selects the Operator Intervention item from the
Commands pull-down menu on the library manager console. Each condition is
listed separately and also indicates the date and time that the condition occurred.

The operator intervention conditions are described in the following set of tables.
Similar conditions are grouped together in each table to make it easier to find a
specific condition. The following table provides a summary of the grouped
