(1) Disconnecting a system board
When 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 commands 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, line monitoring will start normally.
The connection script does not support the disconnecting/embedding of an NIC under a redundant virtual interface comprised of an IPv6 virtual interface and a tagged VLAN interface. If disconnecting the system board using the DR command, first disconnect the NIC built into the system board from the multiplex configuration according to the following procedure. Also, after performing the system board embedding, perform embedding to the multiplex configuration.
For virtual interfaces of dual stack
Delete physical NICs of IPv6 by using the ifconfig command. If the target NIC for DR is the primary interface and the active interface, switch the NIC by using the hanetnic change command beforehand.
For virtual interfaces of IPv6 native or tagged VLAN interfaces
Disconnect NICs by using the same procedure as for the XSCF DR.
