Dynamic system interchange *CALL,DSI
Function
DSI is the JES3 facility that allows a properly configured JES3 local main to assume the role of the JES3 global in the event of a catastrophic error on the current global or if complex reconfiguration is required to prepare for scheduled preventive maintenance. The installation should provide comprehensive procedures for device switching and operator action during DSI. These should be carefully reviewed before and during DSI. Operator messages are provided to guide the operator through DSI; the operator responds with the *S,DSI command.
