Auto-operations interface

An auto-operations interface is provided in TDMF. The interface is a user-selected option, either as the system default, as an option within a migration session, or on a volume level. The intent of this interface is for the control of TDMF sessions. You can enable the option by using the automated operations package, as a user or operator.

If the auto-operations interface is selected, certain TDMF messages are routed to the MVS system console and the TDMF TSO monitor. Action messages can be responded to from either function. TDMF notes and displays where the response originated. All messages that can output to the MVS system console for auto-operations are referenced in documentation. See Messages for automated operations.

The messages that are output to the MVS system console include Action (GTDnnnnA), Informational (GTDnnnnI), and Error (GTDnnnE) types.

Action messages can be canceled by responding with the word CANCEL. A volume or group can stop after a cancel request from the MVS system console or TDMF TSO monitor. They can also stop after a volume pairing failure. In these cases, a GTDnnnnE message displays along with a brief explanation.
