During disconnect processing with the DR command, when the processing stops by inquiry or a situation which must stop the disconnect process according to certain factors occurs, cancellation processing of disconnecting is done.
Similarly, when connecting by a DR command, and a situation by which should case connect processing to be discontinued occurs, cancellation processing of the connection is done.
In the DR script of the Multipath function, reconnect processing is executed as the cancellation processing of disconnecting, and the path is returned to the state before the disconnecting.
- For a Multipath method
When the state before the disconnect is the "active" state or the "standby" state, it changes to the "standby" state. And, when the state before the disconnect is "fail" state or "stop" state, it changes to the "stop" state.
Occasionally, it does not return to the state before disconnecting, if there is hardware breakdown etc.In the cancellation processing of a connection, processing of the re-disconnection is done, and the state is returned to "disconnected" state.
In the case of ATM, all communication paths that correspond to NIC, which is reconnecting or re-disconnecting, are processed.
- For a Multilink Ethernet method
When the state before disconnecting is "active" state, it changes to the "active" state. And, when the state before disconnecting is "fail" state or "stop" state, it changes to the "stop" state.
Occasionally, it does not return to the state before disconnecting, if there is a hardware breakdown etc.In the cancellation processing of a connection, processing of the re-disconnection is done, and the state is returned to "disconnected" state.
