(1) Disconnecting a system board
When cut off using a DR command (drc -disconnect), an actual interface on the corresponding system board is automatically cut off from a virtual interface according to a DR connection script of a Redundant Line Control function.
It is not possible to disconnect a system board if a virtual interface (sha0 etc) and a physical interface have been configured on it. A DR connection script outputs a message and ends abnormally.
In this case, deactivate a virtual interface configured by a physical interface on a system board to be cut off, and execute a DR command (drc -disconnect) after deleted a definition.
(2) Connecting a system board
When connected using a DR command (drc -connect), an actual interface on the corresponding system board is automatically incorporated into a virtual interface according to a description of the configuration information file in a DR connection script of a Redundant Line Control function.
(3) Cancellation
In case the system wants to stop executing DR process due to a certain reason, or if the user requests to stop it while a DR command is executed, the system cancels execution of the DR command.
Through the DR connection script of GLS, the disconnection process can be stopped, and the environment is restored to the original state.
[Notes]
While exchanging a system board containing a physical interface that has been used to configure a virtual interface in NIC switching mode, HUB monitoring function halts temporarily since it is not possible to switch NICs even if an error occurs in a transfer route.
After replacing a system board containing a physical interface used to configure a virtual interface in NIC switching mode, monitoring of a transfer route will start normally.
