With the TS7700 Virtualization Engine there are number of different operational states that get reported to the host that result in CBR-associated messages being issued to the console for the affected distributed library as well as the associated composite library. For some of the operational states, the composite library will also reflect this state if one or more of its associated distributed libraries are in this state and for other conditions, all of its distributed libraries have to be in this state before the composite library reflects this state. Table 1 shows the different operational states, their associated CBR message, and when the composite library will report that it is in the indicated state.
| Library Operational State | Associated CBR Message | Composite Library Reporting |
|---|---|---|
| Automated | CBR3756I | Set if any distributed library is in this state. |
| Paused | CBR3757E | Set if all distributed libraries which contain back end tape are in this state. |
