PRIMECLUSTER Global Link Services Configuration and Administration Guide: Multipath Function (for Solaris(TM) Operating Environment)

8.1.3.1 Operation when disconnecting

• For the Multipath method
  

  If the communication path to disconnect is in the "active" state when disconnecting (drc -disconnect), after changing the communication path in the "standby" state to the "active" state, disconnecting processing of the applicable communication path will be performed in DR script of a Multipath function.

  If the communication path to disconnect is not the "active" state, disconnecting processing is performed as it is.

  If the communication path to disconnect is the active path, and the standby path does not exist, a warning message is displayed and an inquiry regarding processing continuation is done.

  Disconnect processing is done to all communication paths which correspond to the disconnected NIC when the connection is ATM.

  

  • With an ATM connection, do not specify -reset parameter and "-next" parameter, when disconnecting with the DR command.


• For the Multilink Ethernet method
  

  When disconnecting (drc -disconnect), the DR script of the Multipath function disconnects the communication path. If the communication path is the "active" state, the transmission path is switched to another communicating (active) path.

  If the communication path is not the "active" state, it is disconnected as is.

  If the communication path is the "active" state, and no other communicating (active) path exists, a warning message is output asking the user whether to continue or stop communication.
