Abstract: During normal and exception processing within an IBM physical or virtual tape library, intervention or action by an operator or storage administrator is sometimes required. IBM tape libraries have an optional facility that causes a z/OS console message, CBR3750I, to be displayed when intervention or action is needed. The intervention or action may require immediate attention to continue library processing or may be something that can be handled at a later time. The purpose of this white paper is to list the intervention or action messages that are generated and to indicate the importance of each message in regards to how they need to be handled.

Latest update includes for TS7700 Release 4.1.1
