The primary server cannot be switched automatically in the following case:

• If automatic switch/disconnection is disabled

• If output of messages is selected for heartbeat abnormalities during heartbeat monitoring of the operating system or server and the operating system/server crashes or becomes unresponsive

In this case, to manually switch the primary server, execute the mc_ctl command in switch mode on either the primary server or the standby server.

Example)

$ mc_ctl switch -M /mcdir/inst1
