PRIMECLUSTER Global Link Services Configuration and Administration Guide: Redundant Line Control Function 4.1 (for Solaris(TM) Operating System)

2.1.1.2 Switching function

Switching operation

A line whose failure is detected is automatically avoided, and the only normal line takes over the communication. Therefore, if at least one normal line remains, the communication can continue without rebooting the system. It is also possible to disconnect a specific line manually by using the operational command (hanetnic command).

Failback operation

If the faulty line of a physical interface is recovered, the physical interface is automatically restored for normal communication. If a line was disconnected manually, the failback of the line needs to be performed manually to restore the original status.
